ABSTRACT The gingival contour, the color of the teeth and the presence of interincisal diastema are seen as unsightly factors, being highly harmful from a social point of view. The present study aimed to report a comprehensive and conservative esthetic treatment executed with a multidisciplinary approach in a 20-year-old female patient that presented darkened teeth with poor spacing and excessive gingival display while smiling, as well as present a brief literature review on multidisciplinary approach in esthetic dentistry. After clinical examination and diagnosis, a treatment plan was elaborated to meet the patient’s expectations with a conservative approach. After patient consent, therapy began with supervised home-based tooth whitening with 22% carbamide peroxide applied one hour/daily for 14 days, followed with gingival recontouring surgery and, after a healing period of 30 days, diastemas closure with direct composite resin technique, occlusal adjustment, finishing, and polishing. The multidisciplinary approach was fundamental for the accomplishment of the proposed treatment, achieving satisfactory esthetic and functional results.

RESUMO O contorno gengival, a cor dos dentes e a presença de diastemas interincisivos são vistos como fatores antiestéticos, sendo altamente prejudicial do ponto de vista social. O presente estudo teve como objetivo relatar um tratamento estético conservador executado com abordagem multidisciplinar em uma paciente do sexo feminino de 20 anos que apresentava dentes escurecidos com pouco espaçamento e exposição gengival excessiva ao sorrir, bem como apresentar uma breve revisão de literatura sobre à abordagem multidisciplinar em odontologia estética. Após exame clínico e diagnóstico, foi elaborado um plano de tratamento para atender as expectativas do paciente com abordagem conservadora. Após consentimento do paciente, foi iniciada o clareamento dental supervisionado com peróxido de carbamida 22% aplicado uma hora/dia por 14 dias, seguido de cirurgia de recontorno gengival e, após um período de cicatrização de 30 dias, fechamento de diastemas com técnica de resina composta direta. Neste caso, a abordagem multidisciplinar foi fundamental para a realização do tratamento proposto, alcançando resultados estéticos e funcionais satisfatórios.

Abstract Objective: To evaluate the barriers to access and oral health care faced by children and adolescents with Cerebral Palsy (CP) according to their motor impairment through the perception of caregivers. Material and Methods: A case series study was carried out at three health institutions in Pernambuco, Brazil. The study sample consisted of 94 caregivers of 5-to-18-year-old patients with CP, according to GMFCS (The Gross Motor Function Classification System). Data were collected using a semi-structured form to evaluate the barriers to access and analyzed statistically by the chi-square and Fisher exact tests, adopting a 5% level of significance. In addition, binary logistic regression was performed to determine the weight of the variables in explaining the outcome variable. Results: There were major difficulties involving transportation (p=0.04) and structural accessibility to dental services (p<0.01) among children and adolescents with severe CP. In addition, the more severe the CP, the greater the difficulty of accessibility (OR=4.09,) and the lower the income (OR=8.80), the greater the motor impairment. Conclusion: Despite the availability of access to dental services, low-income families have more severe CP patients, contributing to the daily difficulties already faced by them in oral health care.

Aim This study aimed to analyze the influence of finishing and polishing (F/P) protocols on resin surface through roughness (Ra) values and laser scan microscopy observations. Methods Forty-eight (n=48) resin specimens were sorted into four groups (n=12), according to the type of resin used: Filtek Z250 (Z250), Filtek Z350 (Z350), Filtek One Bulk Fill (BF), Filtek P60 (P60). The specimens were sorted into six groups according to the type of F/P system used (n=2/group): Control group, Diamond bur (KG Sorensen), Soflex Pop-On Discs (3M ESPE), Soflex Spiral (3M ESPE), Dura Gloss (American Burs), and Praxis (TDV). Results The highest roughness values (Ra) were attributed to BF group for all F/P systems, except for the Soft-Lex PopOn discs. The Soft-Lex PopOn, Spiral, and Praxis discs presented a better performance for the surface treatment of the tested composite resins. Regardless of the restorative material, the use of diamond bur or single-step abrasive rubber (Dura Gloss) were associated with the highest Ra values. Conclusion The effect of F/P systems on Ra is material-dependent and instrument or system-dependent.

Abstract Objective: To analyze the self-reported need of patients compared to professional indications for tooth whitening. Material and Methods: Initially, 58 undergraduate students responded to a form that highlighted the question: "Do you think you need to have your teeth whitened?" Among those who answered positively to the previous question, ten individuals were photographed with their smiles. In addition, they were asked to point out, on the Vita 3D-Master scale, which color they believed their teeth had, a value that was compared to the actual color obtained by a spectrophotometer. Finally, the photographs were presented to dentists, who were asked about the indication or not of the whitening treatment. Results: Most interviewees (63.8%) self-reported the need for whitening, as well as there was a greater incidence of a positive indication among professionals (53.9%). Pearson's Chi-square test revealed a relationship between patient gender and the training course on the desire to have teeth whitened. Among the professionals, the specialty, as well as time since graduation, interfered in the indication for whitening. Conclusion: Professionals and patients share the aesthetic ideal directly related to light teeth; most patients self-perceive the color of their teeth darker than it actually is; the opinion about the color of the teeth has an extremely subjective character and varies greatly from one professional to another.

Objective: To assess the impact and correlation of socioeconomic vulnerability on COVID-19 outcomes and social distancing in Brazil. Methods: The Gini Coefficient (GC), the Social Vulnerability Index (SVI), epidemiological data on COVID-19 epidemic in Brazil, and the Social Distancing Index (SDI) were retrieved from online databases and assessed for each Brazilian state. Data was statistically analyzed through non-parametric tests and multiple linear regressions. Results: The mean values for the GC and SVI were 0.495 and 0.261, respectively. A positive statistically significant correlation between the socioeconomic indicators and the three variables related to the COVID-19 outbreak was found. States with very low social vulnerability presented fewer deaths per 100 thousand inhabitants due to COVID-19 than states with moderate social vulnerability. SVI was a predictor of accumulated cases, confirmed deaths, and social distancing in Brazilian states during COVID-19. Conclusions: The COVID-19 outcomes and SDI in Brazilian states are correlated to the socioeconomic condition. The pandemic impacts are more severe in less favored communities.

Objetivo: Avaliar o impacto e a correlação da vulnerabilidade socioeconômica nos desfechos da COVID-19 e no distanciamento social no Brasil. Materiais e Métodos: O Coeficiente de Gini (CG), o Índice de Vulnerabilidade Social (IVS), dados epidemiológicos sobre a epidemia da COVID-19 no Brasil e o Índice de Distanciamento Social (IDS) foram obtidos a partir de bases de dados online e avaliados para cada estado brasileiro. Os dados foram analisados estatisticamente através de testes não-paramétricos e de regressão logística linear. Resultados: Os valores médios para o CG e IVS foram 0.495 e 0.261, respectivamente. Uma correlação estatística positiva foi encontrada entre os indicadores socioeconômicos e as três variáveis relacionadas à epidemia de COVID-19. Os estados brasileiros com menores índices de vulnerabilidade social apresentaram uma quantidade menor de mortes pela COVID-19, para cada cem mil habitantes, quando comparados com estados com vulnerabilidade social moderada. O IVS foi um preditor para o acumulado de casos, mortes confirmadas e distanciamento social nos estados brasileiros durante a pandemia da COVID-19. Conclusão: Os desfechos da COVID-19 e o IDS nos estados brasileiros estão correlacionados com a condição socioeconômica. Os impactos da pandemia são mais severos nas localidades mais vulneráveis.
