Item Análise de vídeos do Youtube relacionados a aparelhos ortodônticos fixos e alinhadores ortodônticos(Centro Universitário do Estado do Pará, 2024) Silva, Vitor Costa da; Pinheiro Júnior, Jesus Maués; http://lattes.cnpq.br/0590122765693339In this study, we aimed to assess the accuracy and quality of information presented in YouTube videos related to fixed orthodontic appliances and aligners. YouTube is acknowledged as a powerful source of information on the internet, especially in the realm of health, hosting a variety of orthodontic content. The analysis involved 80 videos reviewed by two orthodontic specialists, focusing on correlating specific data about these orthodontic devices. To evaluate the quality and educational value of the videos, the Video Information Quality Index (VIQI) and the Global Quality Scale (GQS) were employed. Statistical methods such as Kruskal-Wallis and Mann-Whitney U tests were applied for group comparisons, while Spearman's correlation was used, with a significance level of p<0.05. Results revealed that approximately 41.25% of the analyzed videos exhibited moderate usefulness. Interestingly, older videos scored higher in VIQI and usefulness (0,115 and 0,272, respectively), despite having a relatively lower average daily view count (-0.108). The videos available on YouTube regarding this topic are predominantly older and of moderate quality, underscoring the importance of orthodontists updating their content with more recent and engaging material. The lack of popularity might be linked to language usage or lack of appeal, suggesting the need for more captivating approaches to enhance audience engagement.Item Influência do tipo de escova e da força de escovação no desgaste dental erosivo(Centro Universitário do Estado do Pará, 2019) Souza, Cíntia de Melo Silva; Esteves, Renata Antunes; Carneiro, Paula Mendes Acatauassú; http://lattes.cnpq.br/7375951134055063; http://lattes.cnpq.br/0001642348652061; Loretto, Sandro Cordeiro; http://lattes.cnpq.br/6988325260181483; Alves, Eliane Bemerguy; http://lattes.cnpq.br/3442162475756349The objective of this study was to evaluate, in vitro, the influence of manual toothbrushes with different characteristics and two brushing load on microhardness and surface loss of bovine enamel after erosive and abrasive cycling. Specimens of bovine enamel (n = 10) were made in 3x3mm dimensions, where initial erosive lesions were made by citric acid cycling and randomly distributed in 10 experimental groups: A1- Colgate Slim Soft with 1.5N load; A2- Colgate Slim Soft with 3N load; B1- Curaprox 5460 with 1.5 N load; B2- Curaprox 5460 with 3N of load; C1- Oral B Indicator with 1.5N load; C2- Oral B Indicator with 3N load; D1- Johnson & Johnson Professional with 1.5N load; D2- Johnson & Johnson Professional with 3N load; E1- Sensodyne Repair & Protect with 1.5N load; E2- Sensodyne Repair & Protect with 3N load. Microhardness evaluation was performed after abrasive challenge. Surface loss was assessed by non-contact optical profilometry after 5 days erosive and abrasive cycling. Results were evaluated by analysis of variance (ANOVA) and Tukey test, with a significance level of 5%. It was concluded that the microhardness was influenced by the load, where the higher load showed increased hardness when removing the softened enamel layer.? Surface loss was influenced by brush characteristics and load, and soft brushes promoted less surface loss.Item Impacto das soluções irrigadoras na suscetibilidade à fratura de dentes tratados endodonticamente e com lesões cervicais não cariosas(Centro Universitário do Estado do Pará, 2024) Vasconcelos, Alessandra Silva de; Rodrigues, Patrícia de Almeida; http://lattes.cnpq.br/7995657020175355; Brandão, Juliana Melo da Silva; http://lattes.cnpq.br/0139871747607033; Moura, João Daniel Mendonça de; http://lattes.cnpq.br/4761510364570610Endodontically treated teeth are more susceptible to fractures due to tissue loss, moisture reduction, and structural changes caused by intracanal irrigants and medications. Non-carious cervical lesions (NCCLs) also increase dental fragility, making teeth more prone to fracture when treated endodontically. Objective: To evaluate the impact of different irrigating solutions on the fracture resistance (FR) of human teeth with NCCLs treated endodontically. Materials and Methods: Artificial wedge-shaped NCCLs were created on forty-five human premolars with a single root and two canals. Teeth were instrumented using the Wave One Gold “Medium” reciprocating system and divided according to the irrigating solution used: LCNC+NaCl 0.9%, LCNC+NaOCl 2.5%, and LCNC+Test Solution (detergent). All groups received final irrigation using Passive Ultrasonic Irrigation (PUI) with 2.5% NaOCl and 17% EDTA. The canals were obturated and restored, and specimens underwent a compression test. Fracture modes were categorized as favorable and unfavorable. Statistical analysis included the Shapiro-Wilk test for normality, ANOVA, and Tukey’s post hoc test for intergroup comparisons (p<0.05) using Jamovi 1.8.4 software. Results: The highest mean FR was observed in the control group (LCNC+NaCl 0.9%) at 697 N, followed by the LCNC+Test Solution group at 601 N, while the LCNC+NaOCl 2.5% group showed the lowest mean FR at 585 N. Favorable fracture percentages were higher in the LCNC+NaCl (40%) and LCNC+Test Solution (26%) groups, while the LCNC+NaOCl group had a high rate of unfavorable fractures (93%). No significant statistical difference was found between tests groups regarding FR or fracture types observed. Conclusion: Within the limitations of this in vitro study, both 2.5% NaOCl and the detergent solution were viable alternatives to saline control, with no significant compromise in FR in endodontically treated teeth with NCCLs.Item A utilização de um dispositivo para a localização e padronização de imagens ultrassonográficas do coxim adiposo bucal no planejamento cirúrgico de bichectomia(Centro Universitário do Estado do Pará, 2024) Santos, Ana Carolina Bentes dos; Tuji, Fabrício Mesquita; http://lattes.cnpq.br/8122254353290848; Couto, Ana Paula Guerreiro Rodrigues; http://lattes.cnpq.br/2692351198150978; Frazão, Marco Antônio Gomes; http://lattes.cnpq.br/2644040557079748Objective: To locate the Buccal Fat Pad using the UStransfer device for anatomical study and the development of an ultrasonic mapping protocol to assist in the surgical planning of Bichectomy. Methodology: Sixteen patients of both genders, with no prior aesthetic procedures and with the presence of the Buccal Fat Pad, were evaluated. The UStransfer device was used to locate and demarcate the study area, which was subsequently analyzed by ultrasonography (Siemens ACUSON S3000™, HELX™ ultrasound model) on both the right and left sides, using a linear dermatological transducer (Siemens 18L6 HD with a frequency of 6.0 MHz - 18.0 MHz) positioned transversely and longitudinally. Volume measurements were taken at two different times, with a 15-day interval, by the same operator. Additionally, the accuracy rate in identifying the anatomical structure, a descriptive analysis of the volume measurements, and the intraclass correlation (evaluator) were assessed. The BioEstat 5.2 software was used for data analysis, followed by a literature review to deepen the study on the topic. Results: The Buccal Fat Pad was identified in 100% of patients, on both sides and at both time points. The intraclass correlation demonstrated excellent replicability (p<0.0001). There was no significant variation in the volume measurements between the two moments, both on the right side (standard deviation time 1: 0.39; time 2: 0.39) and on the left side (standard deviation time 1: 0.32; time 2: 0.29). An ultrasonic protocol for the Buccal Fat Pad was established to aid in the surgical planning of Bichectomy, using the UStransfer device as a localization method. Conclusion: The mapping using the UStransfer device facilitated the identification of Buccal Fat Pad in ultrasonography, providing an alternative that offers greater safety for the professional performing the surgical intervention and more efficiency for the radiologist in conducting the ultrasound examination.Item Efeito anti-erosivo de géis experimentais a base de própolis sobre lesões iniciais em dentina cervical radicular bovina(Centro Universitário do Estado do Pará, 2024-09-24) Ribeiro, Breno Bevilaqua e Silva; Carneiro, Paula Mendes Acatauassú; http://lattes.cnpq.br/7375951134055063; Alencar, Cristiane de Melo; http://lattes.cnpq.br/4783175034033264; Araújo, Jesuina Lamartine Nogueira; http://lattes.cnpq.br/4860837494466416; Oliveira, Roberta Pimentel de; http://lattes.cnpq.br/6689993037436832Objective: The aim of this study was to evaluate the preventive potential of na experimental propolis-based gels on the inorganic structure of initial dentin erosion lesions. Materials and Methods: Forty bovine cervical dentin samples (4x4x2 mm) were obtained and pre-eroded in a 1% citric acid solution, pH 2.0, for 10 minutes. The samples were then randomized into four groups based on the anti-erosive treatment: G1 – experimental gel without active component; G2 – experimental gel with 0.5% propolis; G3 – experimental gel with 1% propolis; G4 – Ultra EZ desensitizing gel (Ultradent, Indaiatuba, SP, Brazil). Erosion cycling and treatment were performed for 3 days. After cycling, the samples were subjected to 3D profilometry testing to map the surface topography and measure the tooth structure loss (TSL). Scanning electron microscopy (SEM) was then performed for qualitative analysis to assess the surface morphology of the specimens. The One-way ANOVA test, followed by the Tukey post-test, was used to analyze the data. Results: The lowest roughness values were observed in the experimental group G3 (p < 0.05). Additionally, TSL was significantly lower in group G3 compared to the other groups (p < 0.05). The experimental groups G2 and G3 showed obliteration of dentinal tubules. Furthermore, in G3, a high coverage of precipitates on the surface of the samples was observed. Conclusion: Thus, the experimental propolis-based gel at 1% showed promising performance on initial dentin erosion lesions.Item Avaliação de um novo método para estimativa de idade dentária utilizando a cronologia de erupção de Nolla(Centro Universitário do Estado do Pará, 2024) Soares, Igor Pereira; Tuji, Fabrício Mesquita; http://lattes.cnpq.br/8122254353290848; Guimarães, Douglas Magno; http://lattes.cnpq.br/6439076195866691; Oliveira, Clarissa Mendes Lobato de; http://lattes.cnpq.br/6918464982524558; Celestino Júnior, Aluísio Ferreira; http://lattes.cnpq.br/6186863425175415Obtaining an estimate of the dental age of individuals is a matter of great social interest, as it plays an important role in civil and criminal proceedings, as well as in endocrinology, orthodontics and pediatric dentistry. Several studies aim to validate the methods developed in different populations worldwide, while other studies propose new methods. Methods that use the development of atlases as a way of estimating age are also well known, as they provide a direct and more simplified comparison of images. Objective: A study was carried out to evaluate the pattern of dental eruption, based on a modification of the Nolla method using a Brazilian population sample, in order to determine the dental age of these patients. Materials and methods: This was a retrospective cross-sectional study. The total sample required consisted of 572 participants, 286 for each sex and for each gender, in the age ranges from 6 years to 18 years with a 6-month interval. First, intra-examiner and inter-examiner calibration was performed to determine the reliability calculated using Kappa. Stages of dental development of the left hemiarch of the mandible and maxilla of each radiograph were identified. After evaluating the stages of development, the median for each stage and for each tooth was identified. They were tabulated in Excel spreadsheets and statistics were performed to compare with Nolla, demonstrating that there was no statistically significant difference between genders. Based on the results, a more simplified and faster method was proposed to estimate age that can be interpreted by halving the sum of scores covering the age range of 6 to 18 years and 6 months. An age estimation atlas was created, in electronic format (eBook), for estimating age using panoramic radiography in order to offer potential improvements in the workflow of professionals.Item Elaboração e validação de fluxograma de atendimento do paciente com necessidades especiais vinculado à rede de atenção em saúde bucal municipal de Belém(Centro Universitário do Estado do Pará, 2024) Silva, Larissa Lobato; Melo, Ceci Baker de; http://lattes.cnpq.br/8991798067175548In the context of dentistry, a person with a disability (PWD) is someone who faces long-term impairments of a physical, mental, intellectual, or sensory nature, which may hinder their full participation in society, including making conventional dental treatment impossible. These individuals are considered "Patients with Special Needs" (PSN). The objective of this study was to develop and validate a dental care flow for PSN, outlining the roles and responsibilities of Primary Health Care (PHC), the Dental Specialty Centers (DSCs), and hospitals specializing in PSN care. The target audience includes dentists and coordinators involved in the oral health care network of the city of Belém, aiming to promote reception, equal, and high-quality access to dental services for PSN, ensuring inclusion and proper referral for these individuals. The study is divided into three stages: the first stage involved an integrative literature review, the second stage consisted of the development of the flowchart itself, and the third stage focused on its validation through a questionnaire based on a Likert scale, administered by a calibrated researcher to nine expert judges, selected using the Fehring model with adaptations. A Content Validity Index (CVI) was calculated, with a percentage of 70% or higher considered excellent.Item Impacto da manipulação de resinas compostas com luvas de procedimento sobre suas propriedades mecânicas: uma revisão sistemática(Centro Universitário do Estado do Pará, 2024-09-27) Manzoli, Lorâine Perez; Alencar, Cristiane de Melo; Takeuchi, Elma Vieira; http://lattes.cnpq.br/0868780137414166; http://lattes.cnpq.br/4783175034033264; Carneiro, Paula Mendes Acatauassú; http://lattes.cnpq.br/7375951134055063; Silva, Aryvelto Miranda; http://lattes.cnpq.br/0419320072195966Objectives: To perform a systematic review to evaluate the impact of handling composite resin with a procedure glove on the mechanical characteristics of direct restorations. Materials and methods: The PRISMA guidelines for systematic reviews were followed. Experimental studies that evaluated the effect of glove-based composite resin manipulation on the mechanical characteristics of direct restorations were selected. The literature search was performed on September 11, 2024, in the following databases: MEDLINE via PubMed, SCOPUS, Cochrane Library, VHL Regional Portal, and Open Grey Literature. To analyze the risk of bias, this study followed a scoring system adapted from systematic reviews focusing on in vitro studies. Materials and methods: A total of 105 studies were found (94 were removed after removing duplicates and reading the title and abstract). Only 8 articles were selected for qualitative analysis, of which 1 was excluded because it met one or more exclusion criteria. Through a manual search, 2 more studies were included, resulting in 10 articles evaluated at the end of this systematic review. No meta-analysis was performed in this systematic review due to the high heterogeneity between the studies, greater than 50% (I2 = 86%). Conclusion: Most studies have shown that handling composite resins with procedure gloves can cause damage to mechanical characteristics related to surface microhardness, roughness, shear bond, bond strength, compressive strength and adhesive strength of direct restorations. However, cleaning with 70% alcohol appears to partially reverse this process. On the other hand, future research is needed to demonstrate the limited confidence in the estimated effects in this investigation.Item Implementação da clínica de semiologia em um centro universitário do norte do Brasil – relatório técnico científico(Centro Universitário do Estado do Pará, 2024) Freitas, Maurício Sousa de; Carneiro, Marcelo Newton; http://lattes.cnpq.br/7057645859780221Semiology is the science dedicated to the study of signals, during dental care, clinical examination, anamnesis and physical examination are the basis for a correct diagnosis. To this end, every dentist needs to develop some fundamental skills for a correct diagnosis. Among the competencies that govern dental training, the National Curricular Guidelines (DCNs) for the Dentistry course, the dentist must be able to collect, record, organize, analyze and interpret data, clinical and epidemiological information in order to diagnose diseases and oral health problems, in addition to relating them to the individual's systemic conditions in order to incorporate technological innovations during the exercise of the profession. The association between the psychological changes caused by the pandemic and its relationship with Temporomandibular Dysfunction (TMD) resulted in an increase in the incidence and worsening of preexisting conditions. Furthermore, factors such as alcohol and smoking, also aggravated by the pandemic, have resulted in an increase in several lesions that affect the oral cavity. The difficulty in diagnosing them results from the lack of information on the part of the professional or the patient. Furthermore, oral lesions can be divided into benign and malignant, making their investigation important to obtain the most appropriate treatment for each type of lesion. The product started from the idea of a project to create a semiology clinic to initially treat patients with temporomandibular dysfunction and some type of pathology in the orofacial region and was presented to the coordination of the dentistry course. In operation since February 2022, 60 students from two different classes have been trained and more than 300 patients have been treated. Through this technical and scientific report, it was possible to confirm the importance of implementing the semiology clinic, not only for the academic community, but also for society in general. In addition to the treatments offered, there is enormous potential in disseminating information to patients. Therefore, it is suggested that partnerships be formalized and the integrated clinic be separated, so that multidisciplinary care can be provided.Item Estudo de caso sobre coworking odontológico(Centro Universitário do Estado do Pará, 2024-04-29) Santos, Paulo André de Melo; Rodrigues, Patrícia de Almeida; http://lattes.cnpq.br/7995657020175355; Rothbarth, Cláudia Pires; http://lattes.cnpq.br/4295465613640243; Pessoa, Oscar Faciola; http://lattes.cnpq.br/9576667373951387There is a gap in understanding how professionals perceive and use these shared coworking spaces for dentists, as well as the challenges and benefits associated with them. The general objective of this study is to investigate the consumer behavior of self-employed professionals regarding the use of shared space for dental work. This study was conducted in two stages. In the first stage, an interview was conducted with the owner-partners of a dental coworking space to understand its operation, challenges, and opportunities. Based on the information obtained in the interview, a structured questionnaire was developed and applied to dentists through the Google Forms platform. The questionnaire addressed themes such as practical experience with the dental coworking model, motivations for joining or not joining coworking, concerns, and expectations regarding the shared environment, among other aspects. 264 responses were collected over a period of 24 days. The results revealed that most participants are familiar with the concept of dental coworking, although few have practical experience with this model. Cost savings, schedule flexibility, and access to modern technologies were identified as the main attractions of this model, while concerns about privacy, security, and equipment availability still represent challenges to be overcome. This study contributes to understanding the role of dental coworking in the dental workforce in Brazil. By highlighting the benefits and challenges associated with this model of work, it offers valuable insights for professionals, entrepreneurs, and institutions interested in innovating and developing sustainable strategies for the dental sector.Item Fotobiomodulação com led e parâmetros laboratoriais no contexto de mucosite oral após altas doses de metroextrato em pacientes infanto-juvenis(Centro Universitário do Estado do Pará, 2021-04-16) Ferreira, Isabella Melo Brito; Guimarães, Douglas Magno; http://lattes.cnpq.br/6439076195866691; Tuji, Fabrício Mesquita; http://lattes.cnpq.br/8122254353290848; Lima, Rafael Rodrigues; http://lattes.cnpq.br/3512648574555468Cancer is a major cause of death among children and adolescents; and chemotherapy is the most used modality. Among the oral complications developed during chemotherapy treatment, oral mucositis (OM) is the most observed and its treatment is extremely necessary. Photobiomodulation is capable of exerting an analgesic and healing effect on the patient, where it becomes a viable alternative for prevention and treatment in all stages of OM. Objective: to stipulate the effectiveness of LED in the prevention of OM during the treatment of children and adolescents. Method: retrospective analysis of 123 medical records of patients undergoing a photodynamic therapy protocol with LED for treatment and / or prevention of the main oral manifestations related to chemotherapy using the SALUX software (Porto Alegre, RS, Brazil). Results: The LED phototherapy protocol for the treatment and / or prevention of oral mucositis related to chemotherapy was applied in all 118 patients, where 28 patients (23.8%) evolved with OM, of which 10 (35.7% ) were classified as grade 1; 12 (42.9%) classified as grade 2 and 6 (21.4%) as grade 3, with no cases classified as grade 4. It was observed that patients without the prophylactic protocol with LED develop OM 35 times more than patients who received the protocol (p <0.0001). Patients who developed OM presented changes in blood indexes, mainly in hemoglobin, hematocrit, TGP and TGO. Conclusion: photodynamic therapy is effective in preventing OM in juvenile children undergoing chemotherapy, with laboratory values of hemoglobin, urea, TGO and TGP and clinical picture of febrile neutropenia as risk factors for the development of oral mucositis.Item Estudo comparativo do índice de agradabilidade na análise facial para fins de diagnóstico e tratamento ortodôntico(Centro Universitário do Estado do Pará, 2021-03-21) Figueiredo, Luciana Corrêa de; Pinheiro Júnior, Jesus Maués; http://lattes.cnpq.br/0590122765693339; Tuji, Fabrício Mesquita; http://lattes.cnpq.br/8122254353290848; Carneiro, Marcelo Newton; http://lattes.cnpq.br/7057645859780221Orthodontists have the ability to change the facial characteristics of their patients and, consequently, affect their lives. Therefore, it is necessary for them to understand the aesthetic standards for an attractive face. The Subjective Facial Analysis allows the study of aesthetic evaluation performed routinely by society. Through this analysis we classify individuals, according to aesthetic pleasantness, in aesthetically pleasing, aesthetically acceptable and aesthetically unpleasant, according to their personal opinion. One of the objectives of this analysis is to facilitate communication between the patient and the professionals involved in the treatment. In this context, the objective of this study was to verify whether the visualization of two- dimensional (2D) or three-dimensional (3D) images had any effect on the classification of facial attractiveness, seeking to establish a harmonious dentition that is healthy and aesthetically pleasing. The sample of the present study consisted of 50 adult individuals, female and male, with a minimum age of 18 years. In order to determine the subjective aesthetic facial analysis, a group of two orthodontist evaluators, with more than 5 years of experience in the specialty and calibrated in the method, were asked to rate the individuals' facial profile, classifying them as aesthetically unpleasant (1, 2 or 3), aesthetically acceptable (notes 4, 5 or 6) and aesthetically pleasing (notes 7, 8 or 9) in two moments interspersed within 15 days. The evaluations were performed following two forms of image acquisition: the first using standardized photographic images of the face in 2D and the second using standardized images of the face in 3D with the scanner33 SenseTM (3D Systems, Canada). The order of presentation started with 2D images, followed by 3D images, which were presented using the Power PointTM Office 365 software. In order to assess the intra-examiner and inter-examiner agreement in the subjective aesthetic and morphological assessment, the 50 individuals in the sample were evaluated and submitted to the same classification with a 15-day interval between the two assessments. For the analysis of the error, the Kappa coefficient was used, which analyzes the agreement between two non-parametric variables. The Kappa coefficient for intra-examiner agreement between the first and the second evaluation of 2D photographic images was 0.65, whereas for 3D scanned images, the Kappa coefficient was 0.82, demonstrating a high confidence index for this assessment. The evaluation of 3D images also demonstrated a superior result in the confidence level of the same examiner (Kappa 0.67) in relation to 2D photographs. Analyzing all the data of the study together, we verified a greater intra and inter examiner agreement, in the analysis of the 3D stepped images, for the Facial Pleasure index.Item Manual de orientações gerais para atendimento de traumas dentais(Centro Universitário do Estado do Pará, 2021-03-24) Rosales, Pedro Philippe da Silva; Rodrigues, Patrícia de Almeida; http://lattes.cnpq.br/7995657020175355; Celestino Júnior, Aluísio Ferreira; http://lattes.cnpq.br/6186863425175415; Silva, Luciana Jorge Moraes; http://lattes.cnpq.br/2796172853961907Dental trauma is defined as the result of thermal, chemical, or mechanical aggressions caused to teeth and their adjacent structures. These injuries can occur at any age, being common between 8 and 12 years old, affecting permanent dentition, with a higher incidence in boys. This work had as objective the construction of a material of institutional character, directed to dentists and undergraduates of Dentistry, containing the main conducts for the care of dental traumas. For the elaboration of this product, a literature review was carried out in the virtual health library (MEDLINE, LILACS, SCIELO, BBO) using the DECS: Dental Avulsion, Trauma-Dislocation, Dental Trauma, Application of Epidemiology and Brazil. In PubMed the MESH terms: Avulsion, Luxation, Tooth fracture, Epidemiology was used. As inclusion criteria, articles in English and Portuguese, published in the period from 2011 to 2021, of the literature review, case report, epidemiological survey and systematic review type were selected. Papers in other languages and prior to 2010 were discarded. The proposed technical manual disc aims to streamline and optimize the diagnosis and treatment of patients with dental trauma, and is aimed at any dental surgeon, regardless of their specialty and sphere of activity, or undergraduate in dentistry. After the construction of this material, a survey was carried out with 112 participants, for the validation, adjustments, and evaluation of the acceptance of the product in question. Regarding the results obtained, the predominant presence of females and the position of dental surgeons in the private sector was noted, most of the interviewed participants reported having treated more than one patient with dental trauma (61.3%) and that they would use the proposed disc (92.9%), 92% of the participants in this research said they had never seen any material similar to the disc, 86.6% found the disc very useful, 93.8% reported not having difficulty handling it, 92% stated that the disk has all the necessary information and 85.7% would recommend this product to other professionals. The results demonstrate that the instrument created was well accepted by the researched target audience, fulfilling its purpose of optimizing the diagnosis and treatment procedures for patients with dental trauma.Item Resinas bulk fill vs resinas convencionais na sensibilidade pós-operatória: uma revisão sistemática com meta-análise(Centro Universitário do Estado do Pará, 2020-08-10) Giubilei, Fernanda Bernardes; Esteves, Renata Antunes; Alencar, Cristiane de Melo; http://lattes.cnpq.br/4783175034033264; http://lattes.cnpq.br/0001642348652061; Loretto, Sandro Cordeiro; http://lattes.cnpq.br/6988325260181483; Silva, Cecy Martins; http://lattes.cnpq.br/3349622952425723Objective: To compare restorations performed with bulk fill resins vs. conventional resins in relation to postoperative sensitivity, through a systematic review of randomized clinical studies (RCT). Sources: Five electronic databases were searched: Pubmed, Cochrane, Web of science, Scopus and Open gray. Study selection: RCTs that compared the postoperative sensitivity observed in teeth restored with conventional resins vs bulk fill resins were included. Studies that used cavity and / or desensitizing liners were excluded from the study. The risk of bias was classified by the Cochrane guidelines. Two meta-analyzes were performed to assess the postoperative sensitivity of restorations made with bulk fill and conventional resin in the periods of 7 and 180 days. Results: Five RCTs with a low risk of bias were included in the meta-analysis. The evaluation after 7 days was performed in Non-Carious Cervical Injury and in Black classes I and II. Patients who used Bulk fill resins (n = 143) had lower postoperative sensitivity when compared to the use of conventional composite resin (n = 142) (-0.06 [-0.11, -0.01], p = 0.03). The second evaluation, after 180 days, was performed in class V cavities. There was no significant difference in postoperative sensitivity between patients who used Bulk fill resins (n = 125) compared to the use of conventional composite resin (n = 121) in the 180-day period (-0.02 [-0.11, 0.08], p = 0.73). Conclusions: Restorations with bulk fill resins showed lower postoperative sensitivity when compared to restorations using conventional resins up to seven days after restoration and there was no difference in postoperative sensitivity in the 180-day evaluation. However, due to the relatively limited amount of evidence to support this conclusion, more RCTs with a low risk of bias should be performed. Clinical significance: Postoperative sensitivity is very recurrent after restorative treatment, which has led to the development of new materials to circumvent this complication. The restorative treatment using bulk fill resins had a positive effect on postoperative sensitivity when compared to conventional resins within 7 days.Item Desenvolvimento de enxaguante bucal contendo extrato de folhas de Psidium guajava (Myrtaceae) e avaliação da ação antifúgica sobre Candida albicans(Centro Universitário do Estado do Pará, 2020-12-14) Vasconcelos Neto, Raimundo de Souza; Brito, Mileide da Paz; http://lattes.cnpq.br/3493897351649944; Almeida, Fabrício Anderson Carvalho; http://lattes.cnpq.br/0946781923631085; Celestino Junior, Aluísio Ferreira; http://lattes.cnpq.br/6186863425175415Candida spp colonize the skin, gastrointestinal and genitourinary tract and live in our microbiota as commensals, assisting in various functions in the innate defense. On the other hand, these microorganisms can cause cutaneomucosal and systemic infections in humans. Brazil has a wide variety of plants and among them we can find red guava or Psidium guajava. Studies have revealed that P. guajava leaf extract has antifungal activity on Candida spp and concluded that the use of its extract is easy to access and low cost to the population, however it is still being neglected when it comes to oral health. The aim of the present study was to obtain a mouthwash containing extract of leaves of P. guajava on Candida spp. As a result, it was observed the antimicrobial activity described in the literature for the extract, as well as for the proposed formulations, however, some aspects still need to be improved in the formulation, with the product’s flavor and pH.Item Influência erosiva do tucupi na resistência da união ao esmalte e dentina(Centro Universitário do Estado do Pará, 2020-12-16) Carneiro, Reginna Vyctoria da Trindade Souza de Melo; Loretto, Sandro Cordeiro; Ribeiro, Mara Eliane Soares; http://lattes.cnpq.br/5959446285132739; http://lattes.cnpq.br/6988325260181483; Carneiro, Paula Mendes Acatauassú; http://lattes.cnpq.br/7375951134055063; Souza Junior, Mário Honorato Silva e; http://lattes.cnpq.br/9220706169410814The present study evaluated the erosive influence of tucupi on the resistance of the adhesive bond to enamel and dentin. 168 healthy bovine incisors teeth were used, divided into 12 groups (n = 14). For erosive cycling, distilled water (negative control), cola-based soft drink (positive control) and tucupi were used. The adhesive strategies used were: (1) total acid conditioning (conventional) and (2) self-conditioning. All specimens were subjected to cycling with the drinks described above for 5 days and, after 24h of the 5th day, composite resin cylinders were made for the micro shear resistance test. The data showed normal distribution and were analyzed by two-way ANOVA, followed by the Tukey post-test (p≤0.05). There were no significant differences in enamel (p>0.05). In dentin, only the groups exposed to cola-based soft drink showed significant differences (p<0.01). The erosive challenge with tucupi did not influence the bond strength to enamel and dentin, independent of the adhesive strategy used.Item A influência do acesso minimamente invasivo na instrumentação de canais ovais: análise em microtomografia computadorizada e teste de resistência à fadiga flexural(Centro Universitário do Estado do Pará, 2019) Miranda, Ana Raquel Lopes dos Santos; Rodrigues, Patrícia de Almeida; http://lattes.cnpq.br/7995657020175355; Porpino, Mariana Teixeira Maneschy; http://lattes.cnpq.br/5993772430326444; Pessoa, Oscar Faciola; http://lattes.cnpq.br/9576667373951387Purpose: The present study evaluated the type of endodontic access cavity would result in greater or lesser touch on the canal walls during instrumentation, and the influence on the instrument's resistance to cyclic flexural fatigue. Methods: Extracted human mandibular incisors with oval-shaped canals were scanned by Micro-computed tomography for sample selection and distribution in two experimental groups (n = 19), according to the test cavity: Group I, minimally invasive endodontic access (MIA) and Group II, conventional endodontic access (CEA). The canals were instrumented with WaveOne Gold Medium system and irrigated with 2.5% NaOCl and 17% EDTA. After rescanning, the untouched areas were measured and analyzed by reconstructing and overlapping the images. Endodontic instruments were subjected to static flexural cyclic fatigue testing using a stainless-steel artificial canal (60° angle and 5mm radius) located 5 mm from the tip. The instruments (n= 7) were rotated to fracture, and the time in seconds to fracture was recorded using a digital timer. The number of cycles to fracture (NCF) was calculated and statistically analyzed. The data obtained in Micro–computed tomography was analyzed by the T test, Mann-Whitney and Wilcoxon tests. For cyclic fatigue data, Tukey's post-test ANOVA was used. A significance level of 5% was adopted for all analyzes. Results: There was no statistical difference between the groups regarding the walls touched and walls untouched by the endodontic instrument in relation to the variation of the access cavities (p> 0.05). The cyclic fatigue resistance test showed no statistical differences between the groups. Conclusion: Within the limitations of the research, the use of minimally invasive cavities did not interfere in the instrumentation of lower incisors with straight and oval canals, and there was no difference in the resistance to flexural fatigue of the instruments against different accesses.Item Biometria dentária em pacientes padrão I braquifaciais e padrão face curta(Centro Universitário do Estado do Pará, 2019-04-25) Gonçalves Júnior, Carlos Alberto; Pinheiro Júnior, Jesus Maués; http://lattes.cnpq.br/0590122765693339; Pinheiro, Lucas Rodrigues; http://lattes.cnpq.br/9533599258533263; Corrêa, Adriano Maia; http://lattes.cnpq.br/6062379402457289Introduction: Based on studies of the facial morphology of short face (PFC) patients, there is little evidence in the literature to characterize the static and functional occlusion as well as the dimensions of the arches in this pattern of facial growth (PFC). In this perspective, the study aims to compare the results obtained through the measurements in digitized models in brachyfacial I standard individuals and standard short face individuals; to evaluate the transverse and sagittal dimensions of the lower arches in both groups delineated through a trained and calibrated examiner; Observe and discuss whether the results obtained between the two groups outlined and the literature are statistically different or similar. Development: A cross-sectional study was carried out on pre-existing orthodontic documentation selected in the collection of the Specialization Course in Orthodontics of the University Center of the State of Pará (CESUPA). With 40 models of the volunteers of the sample being 20 standard brachyfacial I and 20 standard short face, were scanned optical 3D scanner and the scanned measurements performed through the nemocast® program, randomly and identified by groups and numbered, the measurements were fed into the excel program in The results were submitted to tables with mean, minimum, median and maximum values, standard deviations, the Kolmogorov-Smirnov test evaluated the normal distribution of all variables presented, the t test was performed 'Student and Person's correlation analysis. Conclusion: Based on the measurements performed on the transverse and sagittal dimensions of the lower arch of the two groups Standard I and the Short Face Pattern, the inter-canine, premolar and molar distances of standard Brachifacial I individuals were statistically significant between them , greater than the measurements of individuals Short Face Pattern. The arch length also showed differences in the clinically observed PI> PFC measurements in both groups of the samples. Thus, it was observed that the study showed statistically significant differences between the analyzed groups, corroborating the study of the facial pattern morphology between the patterns analyzed favoring the data specialist of extreme relevance for orthodontic treatment.Item Dexametasona versus laserterapia de baixa intensidade: os efeitos na dor, edema e qualidade de vida após cirurgia de bichectomia: um ensaio clínico(Centro Universitário do Estado do Pará, 2019-09-27) Silva, Diego Assunção Calixto da; Guimarães, Douglas Magno; http://lattes.cnpq.br/6439076195866691; Menezes, Silvio Augusto Fernandes de; http://lattes.cnpq.br/5394614146901551; Carneiro Júnior, José Thiers; http://lattes.cnpq.br/4964530958369814In current study, we aimed to compare the effects of low-level laser therapy and dexamethasone in the pain, swelling and quality of life in patients submitted to buccal fat pad removal. About the methodology, it was surveyed 20 patients who pseudo-herniation of buccal fat pad or aesthetic complaint. The patients were randomly separated into two groups: low-level laser therapy group (LLLT, 660nm, 100mW, 6s, 2J/cm2) and dexamethasone group (DXM, 4mg each 8 hours for 3 days after the procedure). The pain was evaluated through visual analogic scale (VAS) at day 2 and 4 post surgically, to edema evaluation was measured the distance between six reference points: tragus (Trag), pogonion of soft tissues (Pog), lateral corner of the eye (EC), the angle of the mandible (Gon), wing nose (WN) and mouth commissure (MC) at day 2, 4, 7, 15, 30, 60 and 90. To quality of life was applied the Oral Health Impact Profile (OHIP-14) questionnaire at day 2 and 4 after the surgery. It was observed from the results there were no differences between LLLT and DXM at pain and edema. About the quality of life, the LLLT group were more comfortable to chew than DXM (p< 0,05). It was therefore concluded the utilization of LLLT at the parameters of 100mW of power and 2J/cm2 per point demonstrated similar effects of DXM orally in the control of pain and edema, as well as quality of life, except in masticatory function, which LLLT showed better effects.Item Influência do tucupi na rugosidade superficial, microdureza, ultramorfologia e variação de massa do esmalte dental(Centro Universitário do Estado do Pará, 2019) Sousa, Naama Waléria Alves; Loretto, Sandro Cordeiro; http://lattes.cnpq.br/6988325260181483; Esteves, Renata Antunes; http://lattes.cnpq.br/0001642348652061; Souza Junior, Mário Honorato Silva e; http://lattes.cnpq.br/9220706169410814The study evaluated the influence of tucupi on surface roughness, microhardness, ultra morphology and variation of dental enamel. Ninety healthy bovine incisor teeth of the species Bos taurus indicus were used. After the specimens were made, they were divided into the following groups: G1- tucupi, G2- cola-based refrigerant, G3-istilled water, all evaluated at times T0 (before any intervention), T10 (10 days after the proposed treatments), T20 (20 days after the proposed treatments) and T30 (after 30 days of the proposed treatments). In order to evaluate the properties of the treated enamel, microhardness, surface roughness, scanning electron microscopy (SEM) and mass variation analyzes were performed at the 4 times mentioned above. After confirming the normality of the data (Shapiro-Wilk test) of microhardness, roughness and mass variation analyzes, a 2-factor analysis of variance for repeated measures (α = 5%) was performed, followed by Sidak post-test. , with results described as mean and standard deviation. The roughness means increased for all groups tested, with no statistical difference only in G3 for all evaluated times. Regarding microhardness, all groups had loss with the lowest average observed in G1 in T30. In the evaluation of enamel mass variation, the lowest average was in G2 at time T3, with no statistical difference between T10 and T20 for the group in question. Regarding MEV, all groups treated with acid media G1 and G2 showed disorganization of the enamel surface layer. It was concluded that tucupi has low pH and high titratable total acidity, being able to gradually decrease enamel microhardness, increasing surface roughness and causing loss of dental enamel.
