Item Abordagem estética integrada das más oclusões a partir da ortodontia digital: relato de caso(Centro Universitário do Estado do Pará, 2019) Campos, Luís Paulo Almeida; Santos, Nayara Cardoso; Pinheiro Júnior, Jesus Maués; http://lattes.cnpq.br/0590122765693339Dental anomalies are a frequent condition in dentistry. When these malformations are associated with altered dental positioning, they affect aesthetics and function, necessitating an integrated approach between orthodontics and restorative dentistry. In this sense, the present study seeks to report the clinical case of an adolescent patient with malformation in the crown of the upper lateral incisors, diastema in the upper arch and facial growth pattern II, with Class II malocclusion. After evaluation of the clinical condition of the patient, it was verified that a satisfactory outcome of the clinical case would not be obtained if the restorative dentistry procedures were performed alone, as well as those of orthodontics alone. The leveling and alignment of the upper and lower arches was initially planned, using fixed apparatus in the straight arch technique; after the redistribution of spaces, the orthodontic appliance was removed and the patient was referred to perform the restorative procedures. After the clinical intervention, a satisfactory result was obtained for patients and professionals, being made possible by the integration between orthodontics and dentistry. The orthodontics associated to a digital tool can aid in the aesthetic rehabilitation of a patient with dental anomaly in a fast, precise and practical way.Item Abordagem odontológica em mulheres vítimas de violência doméstica: uma revisão de literatura(Centro Universitário do Estado do Pará, 2019-06-03) Martins, Carolina Vitória de Souza; Moreira Júnior, Mário Tavares; http://lattes.cnpq.br/7567611710717172; Miranda, Dóris Kós Burlamaqui de; http://lattes.cnpq.br/1848188497171812; Silva, Clélia Alice Tourinho de Melo e; http://lattes.cnpq.br/2300027513439562Violence against women has serious impacts on the quality of life of these patients, due to physical injuries, besides the psychic and social repercussions. With the purpose of repressing these cases and acting on the violence practiced against the woman that arises the Maria da Penha Law (Law 11.340 / 06). A literature review was conducted to evaluate the knowledge and positioning of dental surgeons in these cases and to analyze how the dental class has behaved in the face of domestic violence in women. It was observed that the CD does indeed act in front of these events, needing to seek more knowledge about the legal issues of the exercise of its profession going beyond the code of odontological ethics, since there are deeper spheres in the Brazilian justice that regulate the actions of the dental surgeons in these cases. The subject covered in this study still presents a lack of data, further research on the subject is required. However, despite the lack of some information and observed that the available literature promotes a good initial foundation on which professional needs to know, although there is disinterest on the part of the category.Item Análise da resistência de união em novas cimentações de laminados cerâmicos após remoção com laser Er:YAG ou ponta diamantada(Centro Universitário do Estado do Pará, 2025-06-02) Rosendo, Alana Mouzinho; Soares, Amanda Celina Pires; Carneiro, Paula Mendes Acatauassú; Alencar, Cristiane de Melo; https://lattes.cnpq.br/4783175034033264; https://lattes.cnpq.br/7375951134055063; Vasconcelos, Bianca Nicoli Lopes de; https://lattes.cnpq.br/9767085206335324The longevity of ceramic laminate veneers can be affected by several factors, which may necessitate their removal. With the advancement of minimally invasive approaches in restorative dentistry, the Er:YAG laser has gained prominence as an effective tool for clinical retreatments. In cases such as fractures, aesthetic alterations, poor adaptation, or patient dissatisfaction, the removal of previously placed ceramic veneers may be required. In such scenarios, laser-assisted removal enables controlled debonding of restorations without significantly compromising the underlying dental structure, allowing for the conservative and safe placement of new ceramic restorations in the same location. Although laser removal appears to be a promising technique to facilitate this process, its effects on tooth structure and influence on subsequent adhesive procedures have been under investigation. The objective of this in vitro study was to evaluate and analyze the bond strength of lithium disilicate ceramic veneers cemented onto bovine dentin, where the previous veneer had been removed using either an Er:YAG laser or a diamond bur. Thirty bovine incisor crowns were used and randomly divided into the following groups (n = 10): G1 – Cementation of ceramic veneer without prior removal (control); G2 – Cementation after veneer removal with Er:YAG laser; G3 – Cementation after veneer removal with a diamond bur. All veneers were bonded using a conventional adhesive system and light-cured resin cement. The veneers were removed following the protocol for each group, and new veneers of the same material were bonded using the same adhesive technique. Subsequently, shear bond strength testing and fracture pattern analysis were conducted. Data were analyzed using oneway ANOVA with a significance level of 0.05. No statistically significant difference in shear bond strength was found among the groups (F(2, 27) = 0.79; p = 0.466), and the predominant fracture pattern in all groups was cohesive (Type 3 – within the resin cement). These findings indicate that the method used for removing the previous ceramic veneer—either diamond bur or highpower laser—did not affect the bond strength of the newly bonded veneer.Item Extrato antioxidante natural do cacau (Theobroma cacao L.) em diferentes veículos reduz a erosão dentinária in vitro?(Centro Universitário do Estado do Pará, 2025-06-05) Bentes, Maria Eduarda Martins; Alencar, Cristiane de Melo; https://lattes.cnpq.br/4783175034033264; Daher, Sandra Chaves; https://lattes.cnpq.br/6353400984683298; Caracas, George Clay dos Santos; https://lattes.cnpq.br/0243457123378494This study aimed to develop and evaluate the anti-erosive potential of a solution and an experimental toothpaste enriched with natural antioxidants derived from cocoa (Theobroma cacao L.) on eroded dentin in vitro. The cocoa beans went through a process of fermentation, drying, roasting and grinding, followed by freeze-drying and obtaining aqueous cocoa extract. The extract was analyzed for total polyphenols and antioxidant potential using the DPPH (2,2-Diphenyl-1-Picrylhydrazyl) assay. After, an active ingredient-free toothpaste was developed and enriched with the concentrated cocoa-based polyphenol solution. The antioxidant potential of toothpaste enriched by DPPH. Eighty bovine dentin samples were pre-eroded in citric acid solution and randomized into three groups (n=20): G1 (Negative control) – toothpaste without active ingredients; G2 – concentrated cocoa-based polyphenol solution; G3: experimental toothpaste enriched with a concentrated cocoa-based polyphenol solution; and G4 (Positive control) – Elmex Protect anti-erosive commercial toothpaste (Colgate). After applying the materials, the erosive challenges were performed for 3 days, the eroded dentine surface loss (dSL-eroded) was determined by optical profilometer. The amount of degraded collagen (dColl) was calculated as the difference between (dSL-eroded) and (dSL-total - by immersing them individually in a saline solution containing type VII collagenase). Total calcium release (CaR) were evaluated by atomic absorption spectrometer. Additionally, qualitative surface analysis was performed using scanning electron microscopy (SEM). Data were analyzed using one-way ANOVA followed by Tukey's post hoc test (α = 0.05). The results showed that the cocoa extract presented a higher value of total polyphenols when compared to the toothpaste enriched with cocoa extract (p = 0.037). The antioxidant activity data showed a significant decrease when the toothpaste was manipulated (p = 0.025). Group G2 exhibited the lowest values for total dSL-eroded, dColl, and dSL-total when compared to other groups (p< 0.05). Group G2 exhibited the lowest values for calcium released to the citric acid (p< 0.05). In the SEM images, G3 showed dentine surface topography pattern with the presence of partially or total occluded dentinal tubules after treatments. This study demonstrated that the cocoa extract exhibited a higher total polyphenol content compared to the toothpaste enriched with cocoa extract. The proposed experimental solution showed an anti-erosive effect, preventing both organic and inorganic wear of dentin and promoting partial obliteration of dentinal tubules.Item Restabelecimento da dimensão vertical de oclusão em paciente com overbite acentuado: relato de caso(Centro Universitário do Estado do Pará, 2019) Saraiva, Edimara da Costa; Nascimento, Francisca Sarah Moreira; Corrêa, Davi Lavareda; http://lattes.cnpq.br/1363928397942822Objective: To report a case of oral rehabilitation of a patient with severe loss of vertical dimension of occlusion caused by posterior dental element loss. Case report: A 62-year-old female patient presented to the clinic of the University Center of the State of Pará (CESUPA). The patient reported dissatisfaction with her smile. Clinical examination showed marked midline diastema and alteration of the vertical dimension of occlusion caused by the absence of posterior dental elements. Conclusion: This report illustrates another case of oral rehabilitation in which it was possible to increase the patient’s vertical dimension of occlusion, through semi adjustable articulator with intra oral registration protruding the jaw, bringing facial harmony, aesthetics, and chewing function.Item Tratamento da má oclusão de classe II divisão 1 em duas fases utilizando splint maxilar e aparelho autoligado(Centro Universitário do Estado do Pará, 2019-06-04) Rocha, Amanda Cruz; Pinheiro Júnior, Jesus Maués; http://lattes.cnpq.br/0590122765693339; Penin, Thaís Buenaño; http://lattes.cnpq.br/9954742909174950; Gonçalves, Carlos Alberto; http://lattes.cnpq.br/2412791031421616To carry out a review of the literature on the treatment of Pattern II by maxillary protrusion and Class II, Division 1 malocclusion and its different possibilities of approaches, and present a case report in two phases. The databases BIREME, Google Academic and Pubmed were used to obtain articles in English and Portuguese. For the search strategy we used the terms Boolean AND, AND NOT and OR to order the key words and delimit the object of study. It has been verified in the literature that the two-stage treatment can be performed using the "Maxillary splint" device in the mixed dentition, to approach the maxillary protrusion and in the sequence in the young permanent denture period the fixed self-ligating device for the refinement of static and functional occlusion. The approach of Class II malocclusion in Pattern II by maxillary protrusion can be performed in two phases, a fact corroborated by the successful treatment performed and by the literature evaluated in this study.
