ABSTRACT
AIMS: The people with intellectual disabilities have been reported to be a vulnerable population in terms of oral health. This study was carried out to determine the oral health condition and treatment needs of Special Olympics athletes in Brazil. METHODS: This study is a retrospective review of oral health data collected from athletes participating in Healthy Athletes Program Special Olympics in Brazil, between the years 2015 and 2019. About 1241 athletes from the Brazil Special Olympics program were screened in the cities of São Paulo, Jundiai and Belo Horizonte (located in southeastern Brazil) and Recife (in northeastern Brazil). At each of these events, volunteer dental professionals performed an oral health screening for each athlete, All oral health assessments were done visually; and extra lighting were available if needed. The examinations were performed with the aid of a wooden spatula of the tongue depressor type and under natural light. The following parameters were recorded: mouth pain, untreated tooth decay, missing teeth, gingival signs, urgency and mouth hygiene habits. Data was analyzed using the STATA 14.0 program. Frequency tables were used for descriptive analyses. Categorical variables were compared between the different years of the event using the Chi-Square or Fisher's Exact test. Continuous variables were compared between different event years using the Kruskal-Wallis test followed by Dunn's post-hoc analyses. Simple logistic regression was used to assess the effect of age on dental assessment results. For all tests, a p-value was considered significant when less than or equal to .05. RESULTS: No statistically significant differences were observed in the frequencies of Mouth Pain and Missing Teeth over the years (p > .05). In relation to Untreated Tooth Decay, there is a higher frequency in the years 2016 and 2018 and a lower frequency in the year 2015 (p = .048). Regarding Gingival Signs of inflammation, there is a higher frequency in the years 2016 and 2018 and a lower frequency in the year 2017 (p < .001). In relation to cases of urgency (in need of treatment (Urgent treatment need, Non-Urgent or Maintenance)), there was a higher frequency (no urgency) in 2016 (p = .007). Finally, in relation to mouth hygiene habits, there is a higher frequency of participants with irregular habits in the years 2017 and 2019 (p < .001). CONCLUSION: The dental condition of Brazilian athletes Special Olympycs Brazil reported in this study from 2015 to 2019 showed us that athletes have a high prevalence of dental diseases and these needs could contribute to health damage. The athletes have many unmet dental treatment needs and these needs are similar in different regions of the country and in the years reported.

The aim of this study was to evaluate the fracture resistance of 2 different types of all-ceramic crown using immediate dentin sealing (IDS), obtained using a CAD/CAM system on molars with different preparations. Forty extracted lower molars were endodontically treated and divided into four groups (n = 10) according to the dental preparation. Group 1 (SP0) was prepared without filling the pulp chamber and crown-root junction was located at the cementoenamel junction (CEJ). Group 2 (SP1) was prepared without filling the pulp chamber and crown-root junction was located 1-mm above the CEJ. Groups 3 and 4 contained a flat preparation surface with no axial wall height. Group 3 (CP0) was made IDS with complete filling of the pulp chamber with composite resin and crown-root junction was located at the CEJ. Group 4 (CP1) was prepared with complete filling of the pulp chamber and crown-root junction was located 1-mm above the CEJ. All groups were restored with CAD/CAM lithium disilicate ceramic crowns. Specimens were subjected to the fracture test and statistically analyzed using analysis of variance (ANOVA). Fracture mode was determined using a stereoscopic microscope, classified as repairable or nonrepairable, and analyzed using Fischer's exact test. Results indicated that there were no significant differences between the groups in terms of fracture resistance or fracture pattern (p >0.05). Fracture resistance was the lowest in the SP0 group, followed by the SP1 group (1634.38 N) of CP0 (1821.50 N), and it was the highest in the CP1 group. There was a predominance of nonrepairable fractures and there were no significant differences in the fracture resistance and fracture mode of CAD/CAM lithium disilicate molar all-ceramic crowns. Endodontically treated molars teeth might be restored with endocrowns or all-ceramic crowns on flat preparation; however tooth fracture failures that affect reliability of these types of restorations should be considered.
ABSTRACT
Este trabalho mostra uma técnica de preparo dental denominada de "Técnica de Referência para Preparo Dental Inoue & Zanetti". Esta técnica foi inspirada no desgaste através da confecção de sulcos de orientação e ao contrário da maioria das técnicas de preparos que utilizam sulcos verticais, nesta técnica os sulcos são horizontais. Foi idealizado um kit de pontas diamantadas especiais de uso sequencial (kit Inoue/Zanetti/Feltrin - kg - Sorensen- ref. 6727) e foram desenvolvidas pontas específicas para espessura de desgaste desejada em função do tipo de coroa selecionada. Os instrumentos cortantes rotatórios foram idealizados para que o desgaste seja mínimo sem prejudicar a estética na região cervical. Consequentemente terá um menor dano ao periodonto de proteção facilitando a moldagem e a cinta metálica das coroas metalocerâmicas poderá ser menor, facilitando à estética. Os tipos de terminações marginais também são analisados, conferindo ao degrau inclinado 1350 a terminação ideal para coroas metalocerâmicas em dentes anteriores.
The paper presents a tooth preparation technique called "Inoue & Zanetti Dental Preparation Technique". This technique was inspired in the confection of orientation sulci. A special diamond burs points was created (The Inoue/Zanetti/Feltrin diamond points kit - KG - Sorensen- ref. 6727) specific for the obtainment of the desired amount of wear, for each kind of tooth preparation. Cutting rotatory instruments were developed in order to demand less dental waste without damage in the periodontal tissues. The kit enables the operator to confect aesthetic restorations with the amount of wear and marginal endings of 1350, specific for metalloceramic crowns in anterior teeth..
ABSTRACT
O tratamento de remanescentes radiculares, muitas vezes é inviável pelas suas características clínicas e radiográficas, havendo necessidade de extração. Apesar do advento dos implantes, este relato de caso clínico discute o tratamento por meio de uma prótese parcial fixa alternativa após a extração de um remanescente radicular anterior. O resultado do tratamento demonstrou sucesso funcional e estético. Foi preservado um dos elementos de suporte pela utilização de sistema de encaixe adesivo CWB como um dos retentores, e no outro dente suporte foi indicada uma coroa metaloplástica veneer de confecção retrógrada, uma vez que a mesma é retentor indireto de uma prótese parcial removível recém confeccionada. É descrito também o condicionamento tecidual pós-exodontia, com prótese provisória para receber o pôntico oval

Este trabalho mostra uma técnica de preparo dental inédita denominada de "Técnica de Preparo Dental Inoue & Zanetti". A técnica foi inspirada na confecçäo de sulcos de orientaçäo. Por isso, a equipe de Prótese Parcial Fixa da UNICID criou pontas diamantadas especiais, específicas para a espessura de desgaste desejada para cada tipo de preparo. O kit de pontas diamantadas Inoue-Zanetti-Feltrin (ref. 6727) foi confeccionad em parceria com a KG Sorensen. Com esse kit, o operador pode realizar restauraçöes estéticas ("inlays", "onlays" e facetas laminadas), coroas parciais (MOD, 4/5) e coroas totais (metálicas, metaloplásticas e matalocerâmicas), com quantidade de desgaste e terminaçöes marginais específicas para cada tipo de preparo
