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.Item Efeitos comparativos da fotobiomodulação utilizando laser de baixa intensidade ou diodo emissor de luz na mucosite oral em pacientes pediátricos que receberam altas doses de metroextrato: estudo prospectivo, randomizado e controlado(Centro Universitário do Estado do Pará, 2019) Ota, Tâmara Melo Nunes; Guimarães, Douglas Magno; http://lattes.cnpq.br/6439076195866691; Tuji, Fabrício Mesquita; http://lattes.cnpq.br/8122254353290848; Ribeiro, André Luis Ribeiro; http://lattes.cnpq.br/9899528924354409Purpose: The objective of this study was to compare the efficacy of photobiomodulation using low-level laser therapy (LLLT) or light emitting diode therapy (LEDT) devices for the prevention of oral mucositis in pediatric patients diagnosed with acute lymphoblastic leukemia undergoing chemotherapy with high doses of methotrexate (MTX). Methods: 80 patients were randomly divided into two groups: LLLT and LEDT. Both protocols were applied with the same energy and radiant exposure. The protocols started in the beginning of high doses MTX and finished when the patients were discharged from the hospital or there was oral mucositis resolution. The oral mucositis was assessed during each session in accordance to the World Health Organization (WHO) score. The patients self-assessed pain was scored on a visual analog scale (VAS). Results: the incidence of oral mucositis was similar to LLLT and LEDT, 10% and 12,5% respectively. Both groups required the same number of days to reach score of zero for mucositis and pain (p > 0.05) and there was no significant difference in mean VAS between the groups. Conclusions: These findings suggest that LEDT has similar effects to LLLT and can be a low cost and easy application tool to avoid and treat oral mucositis.Item Prevalência e perfil de resistência dos principais agentes microbianos bucais associados à pneumonia nosocomial de um hospital púbico do estado do Pará entre 2014 e 2017(Centro Universitário do Estado do Pará, 2018) Araújo, Andreia de Fátima de Souza; Celestino Júnior, Aluísio Ferreira; http://lattes.cnpq.br/6186863425175415; Menezes, Silvio Augusto Fernandes de; http://lattes.cnpq.br/5394614146901551; Tuji, Fabrício Mesquita; http://lattes.cnpq.br/8122254353290848The multiresistance of antimicrobial drugs is an increasingly worrying phenomenon in anti-infective therapy, especially in critical patients such as those receiving health care in Intensive Care Units (ICUs). This becomes even more problematic when it comes to patients admitted to these units as they are more vulnerable to opportunistic infections. The absence of oral care in these patients can lead to the spread of infections to the rest of the body, among them Nosocomial Pneumonia, of recognized high prevalence and lethality. This study aims to identify the prevalence of oral infectious agents in patients treated at ICUs on a public hospital, in the state of Pará, between 2014 – 2017, and to assess the sensitivity and resistance profile of the main microorganisms associated with these infections in 489 patients of this hospital. Pseudomonas aeruginosa and Acinetobacter baumannii were the most prevalent agents (p<0.05) among patients with VAP, and Carbapenens (47.62%) and Cephalosporins of the 3rd and 4th generation (14.29%) the antibiotics that showed more resistance for Pseudomonas. Carbapenens were also more resistant to Acinetobacter (55.5%), followed by 3rd and 4th generation Cephalosporins, Imipenem, Meropenem, Quinolones and Ampicillin + Sulbactam (6%). PAV was the most frequently found infection site in the studied sample, with Pseudomonas aeruginosa and Acinetobacter baumannii being the most prevalent bacteria, and the antibiotic Carbapenens presented the highest resistance to both.Item O efeito da miliamperagem na detecção do canal mesiopalatino de molares superiores em tomografia computadorizada de feixe cônico(Centro Universitário do Estado do Pará, 2018) Ribeiro, Camila Ribeiro; Rodrigues, Patrícia de Almeida; http://lattes.cnpq.br/7995657020175355; Pessoa, Oscar Faciola; http://lattes.cnpq.br/9576667373951387; Tuji, Fabrício Mesquita; http://lattes.cnpq.br/8122254353290848Introduction: This study tested the accuracy of the Cone Beam Computed Tomography (CBCT) on the detection of the mesiopalatine canal (MPC) treatment of the first permanent molars after the instrumentation and obturation of the root canals with a variation on the milliamperage (mA) values. Methods: The first twenty first permanent molars were divided, initially, in two groups: I) teeth which had three root canals and II) teeth which had four root canals. The canals were prepared with the Protaper Next system until the instrument X3, irrigated with a sodium hypochlorite solution at 2,5% and endodontically treated by the only beam technique and the AH Plus cement. The MPC of group II was not instrumented nor endodontically treated. The images were acquired using the Pax-I 3D tomograph in two distinct moments, after instrumentation and endodontic treatment applying different mA values: 3mA, 5mA and 10mA. The criteria for the analysis of the images were the CBTC images versus the gold standard (tooth). It was attributed a scale of five points: 1) there is no mesiopalatine canal surely; 2) there is no mesiopalatine canal probably; 3) incertitude; 4) there is a mesiopalatine canal, probably; 5) there is a mesiopalatine canal surely. The agreement inter and intra observer was calculated using the Kappa ratio. The responses were analyzed by the calculation of the curve of characteristic of operation of the receptor (ROC), determining the values of sensibility, specificity and accuracy of the images’ modality. The obtained values were compared by the ANOVA test, adopting 5% as the level of significance. Results: The obtained Kappa values indicated good and excellent agreement intra and inter observer, the area below the ROC curve (ASC) varied from 0.91 to 0.97, sensibility from 8% to 95%, specificity from 70% to 90% and accuracy from 77,5% to 90%. There was no statistic difference between the tested protocols. Conclusion: Within the limits of this study, all the protocols can be applied to the detection of MPC in teeth endodontically treated or nor endodontically treated., being recommended the protocols of a minor dose of radiation.Item Caracterização e análise do potencial antimicrobiano do óleo essencial da Lippia thymoide frente a Fusobactérium nucleatum(Centro Universitário do Estado do Pará, 2018-12-06) Tanaka, Erich Brito; Rodrigues, Tânia Maria de Souza; http://lattes.cnpq.br/4924941383324071; Tuji, Fabrício Mesquita; http://lattes.cnpq.br/8122254353290848; Melo, Mauro André Damasceno de; http://lattes.cnpq.br/9472853779075122This study aimed to discover the chemical components and to analyze the antimicrobial activity of Lippia Thymoide essential oil on the Fusobacterium Nucleatum (FN) strain. Based on the information that this anaerobic bacterium is highly pathogenic to the oral cavity, the essential oil was obtained by the hydrodistillation method and its chemical composition was discovered using gas-liquid chromatography coupled to mass spectrometry (GC- MS). Responses to the sensitivity test (15 mm) and the minimum inhibitory concentration (1.6 μg / ml), compared to the control test using the antibiotic Vancomycin sensitivity (34 mm) and MIC (0.16 μg / ml) its high antimicrobial potential against FN and a possible weapon to combat serious periodontal diseases.Item Avaliação da presença de frenestrações e deiscências em pacientes classe I e III por meio de tomografia computadorizada de feixe crônico: estudo transversal(Centro Universitário do Estado do Pará, 2018) Oliveira, Juliana de Souza; Pinheiro, Lucas Rodrigues; http://lattes.cnpq.br/9533599258533263Fenestrations and dehiscences are bone resorptions that require great care by the orthodontist at the time of orthodontic movement. Cone – beam computed tomography scans are the best option for the correct diagnosis of such defects. The aim of this research was to verify the presence of fenestrations and dehiscences in patients with Class I and III from the second molar to the second molar on the opposite side, upper and lower, by cone – beam computed tomography of the particular collection of a radiological clinic. The samples were divided into 25 class I and 25 class III patients, than an orthodontist and a radiologist, in agreement, performed the scans to determine the presence or absence of bone defects, 15 days later 30 % of the sample was reevaluated. The reproducibility of the analysis was tested using the Kappa test and the null hypothesis with test χ2 resulting in a statistically significant difference between the class I and III groups, a higher prevalence of dehiscences in the maxilla of class I patients and a greater presence of fenestrations in the maxilla of patients class III.Item Conhecimento dos ortodontistas de Belém-PA sobre a síndrome da apneia obstrutiva do sono(Centro Universitário do Estado do Pará, 2018) Cristino, Márcio Ruffeil; Pinheiro Júnior, Jesus Maués; http://lattes.cnpq.br/0590122765693339; Ribeiro, André Luis Ribeiro; http://lattes.cnpq.br/9899528924354409; Guimarães, Douglas Magno; http://lattes.cnpq.br/6439076195866691Introduction: Obstructive Sleep Apnea Syndrome (OSAS) is a sleep disorder characterized by repetitive episodes of upper airway obstruction that occur during sleep. The treatment of OSAS is multidisciplinary, being the dentist, especially the orthodontist, one of the members of this team that plays a very important role in the treatment of OSAS. Objective: To evaluate the level of knowledge of orthodontists regarding different aspects of the OSAS, its diagnosis and treatment. Material and Methods: Fifty-two professionals specialized in orthodontics and a questionnaire was applied containing 11 questions related to the knowledge about OSAS, each question with 7 possible alternatives. After getting the data, the answers were analyzed and grouped into three groups that classified the level of knowledge about SAOS: low (0, 1 and 2), medium (3 and 4) and high (5 and 6). Results: 82.69% of the participants had previous knowledge of OSAS; 75% had no information during the undergrad course and 34.62% did not get any information during the orthodontics training; 42.31% have a high level of knowledge for the signs of OSAS, 40.38% reported to know the symptoms and how to make the diagnosis of OSAS; only 34.62% of participants reported knowing how to treat the OSAS. Conclusion: It was concluded that most of the specialists did not have undergraduate and postgraduate information about the OSAS, suggesting a deficient curriculum. However, the level of knowledge of signs, symptoms and the diagnosis of OSAS grows after undergraduation/orthodontics training, suggesting that these professionals acquired complementary knowledge by other means (e.g. readings, courses, and so on). Most orthodontists reported low knowledge about how to treat OSAS.Item Avaliação da alteração de cor e rugosidade superficial de resinas bulk fill após escovação mecânica e envelhecimento(Centro Universitário do Estado do Pará, 2018) Balla, Mariana Vieira; Esteves, Renata Antunes; http://lattes.cnpq.br/0001642348652061The objective of this study was to evaluate, in vitro, the color stability (ΔE) and the surface roughness (Ra) of bulk fill (Filtek Bulk Fill e Tetric N-Ceram Bulk fill) and conventional (Filtek Z350XT e Filtek Bulk fill) composites, after mechanical brushing and aging. Specimens were made (n=5), with rounded bipartite matrix (8mm diameter x 4mm thickness). They were evaluated for color change (Spectrophotometer, Color Guide, BYK Gardner) and surface roughness (PROSCAN 2100 3D optical profilometer; Scantron), initially and after the tests. They were divided into 3 groups according to the tests: A-brushing (14,600 cycles, mechanical brushing machine, Elquip); B-thermocycling (5,000 cycles, 5-55°C, 30 seconds, Thermocycler, New Ethics-Scientific Equipment S.A.); C- thermocycling followed by brushing (same protocol). After all evaluations, the means were calculated and compared by means of analysis of variance (ANOVA) and Tukey's test. The level of significance was 5%. It was concluded that all resins were influenced by brushing and thermocycling. But the resin that suffered the most changes in color and roughness after mechanical brushing and thermocycling was Tetric N-Ceram Bulk fill resin.Item Análise da IL-10 em pacientes portadores do HIV-1 com periodontite crônica no norte do Brasil(Centro Universitário do Estado do Pará, 2018-03-09) Fonseca, Ricardo Roberto Souza; Menezes, Silvio Augusto Fernandes de; http://lattes.cnpq.br/5394614146901551; Celestino Júnior, Aluísio Ferreira; http://lattes.cnpq.br/6186863425175415; Rodrigues, Tânia Maria de Souza; http://lattes.cnpq.br/4924941383324071Aim: The objective of this study was to investigate the levels of IL-10 in the gingival crevicular fluid in HIV-1 positive patients with chronic periodontitis and to compare with HIV-1 negative patients with chronic periodontitis, also to correlate clinical periodontal parameters, viral load and count of CD4+ and CD8+ lymphocytes (LTCD4+ and LTCD8+). Methods: 33 patients were selected and splitted into two groups: 16 HIV-1 positive patients and 17 HIV-1 negative patients and all with chronic periodontitis. The clinical periodontal parameters recorded were: Probing Depth (PD) and Clinical Attachment Level (CAL); the sistemical parameters LTCD4+, LTCD8+ and viral load were analized by the gingival crevicular fluid collected from all patients. Enzymelinked immunosorbent assay (ELISA) was used to determine the concentrations of Interleukin (IL)-10. For the statistical analysis the Student t, Mann-Whitney and Spearman tests were performed. IL-10 levels were significantly lower in both patients groups. Results: There was statistical difference betwen groups for probing depth (p=0.015) and clinical attachment level (p=0.011), no significant correlation was found among the analyzed variables. Conclusion: The IL-10 levels in HIV-1 positive patients had no influence in periodontal and immonological parameters.Item Análise da atividade microbiana do extrato de Lippia thymoide, frente a cepa de p. intermediária(Centro Universitário do Estado do Pará, 2018) Carvalho, Tábata Resque Beckmann; Menezes, Silvio Augusto Fernandes de; http://lattes.cnpq.br/5394614146901551; Brito, Mileide da Paz; http://lattes.cnpq.br/3493897351649944; Carvalho Junior, Raul Nunes de; http://lattes.cnpq.br/5544305606838748Lippia Thymoide (LT) is used in Western medicine to treat respiratory infections, periodontal diseases and periodontal diseases, anti-inflammatory, antibiotic, among others that are related in the literature, the objective of this study is to evaluate the chemical composition of essential oil of Lippia Thymoide and its antimicrobial activity against Prevotella Intermediate (PI) strains and the prevalence of the diagnosis of periodontal diseases. Methodology: the hydrodistilation process was identified and tested through a Minimum Inhibitory Concentration (MIC) test and resistance test against a bacterium. Results: The essential oil of an anti-inflammatory diet relative to pre-medial periodontopathogenic interactions is 6.5 μg / ml and a positive capacity test. Conclusion: the results found in our research demonstrated that the oil of LT, dependent on seasonality, are promising, are a great bacterial potential and becomes a great ally for the manufacture of products that complement the treatment of periodontal diseasesItem Avaliação do padrão de crescimento facial e da má oclusão em uma população de indivíduos em dentadura mista e uma proposta de gestão para saúde pública(Centro Universitário do Estado do Pará, 2022-01-31) Silva, Adriana Viana Martins da; Pinheiro Júnior, Jesus Maués; http://lattes.cnpq.br/0590122765693339; Celestino Júnior, Aluísio Ferreira; http://lattes.cnpq.br/6186863425175415; Corrêa, Adriano Maia; http://lattes.cnpq.br/6062379402457289Malocclusion is the set of changes in bite relationships, which can have consequences on adjacent structures of the masticatory system and orthodontic problems, which can be dental or skeletal. Malocclusion is considered a public health problem and ranks third among oral pathologies. It can cause several changes in an individual’s life, such as imparing the quality of life, social interaction, psychological well-beign and even resulting in functional limitations in more severe casas. During mixed dentition, arch changes occur and normal changes may also occur. In this context, the current study aimed, through the analysis of the medical records of the Clinic of the Specialization Course in Orthodontics, CESUPA-Center for Higher Studies of the State of Pará, of 655 children, aged between 9 and 11 years, develop the epidemiological assessment of patients to later describe the facial growth pattern, determine the need for orthodontic treatment plan for each patient and, mainly, prepare a spreadsheet with the costs for each treatment. The results showed: growth pattern, facial pleasantness index, facial typology, molar relationship, deep bite, open bite, anterior and posterior crossbite, diastema, crowding and early tooth loss. With these results, together with the spreadseet with the costs of each case, it is expected that they will be used fir the implementation of orthodontics in municipal ans state dental speciality centers, so that more people have acess to this type of treatment.
