Short and long effects of the COVID-19 context on oral health-related quality of life of adolescents.

AIM: To assess the immediate and late effects of the COVID-19 pandemic on the oral health-related quality of life (OHRQoL) of adolescents. DESIGN: This is a longitudinal study performed with adolescents (11-15 years old) from Southern Brazil who were evaluated before the COVID-19 outbreak, and 3 (T2) and 15 (T3) months after the beginning of the pandemic. OHRQoL was assessed using the CPQ11-14. Sociodemographic and clinical variables were also collected. Changes in OHRQoL before, 3 and 15 months after the start of the pandemic were analyzed through multilevel Poisson regression models for repeated measures. RESULTS: A total of 290 adolescents were evaluated at T1, 207 were re-evaluated at T2, and 204 at T3. Overall CPQ11-14 scores over follow-ups were 11.0 (SD 8.0) at T1, 8.3 (SD 7.8) and 12.8 (SD 8.8) at T3. Compared to T1, adolescents presented 29% lower overall CPQ11-14 scores (IRR 0.71 95% CI 0.66-0.75) at T2, and 11% higher scores at T3 (IRR 1.11 95% CI 1.05-1 0.17), especially for the emotional and social well-being domains. CONCLUSION: COVID-19 pandemic impacted the adolescents' OHRQoL differently over time, indicating a reduction in impacts immediately after the beginning and worsening over long term exposure to this scenario.

Impact of the COVID-19 pandemic on sleep bruxism among adolescents in Brazil: A longitudinal study.

AIM: To evaluate the immediate and late impact of the COVID-19 pandemic on the occurrence of possible sleep bruxism (SB) among adolescents in Brazil. DESIGN: This is a longitudinal study performed with adolescents (11-15 years old) from Southern Brazil. Baseline data were collected before the Brazilian COVID-19 outbreak (T1). Posteriorly, data were collected after 3 (T2) and 15 months under the Brazilian COVID-19 outbreak. The possible SB was evaluated by the question: 'Do you grind your teeth during your sleep?'. Sociodemographic, psychosocial and clinical variables were also collected. Changes in SB were evaluated by multilevel logistic regression models for repeated measures. RESULTS: Of the 290 adolescents assessed at T1, 182 were reassessed at both follow-ups. The prevalence of possible SB was 13% at T1, 11% at T2 and 22% at T3. There were no immediate effects of the COVID-19 pandemic on the occurrence of possible SB (T2). Adolescents had odds 2.77 times greater of presented possible SB after 15 months (T3) of COVID-19 pandemic scenarios when compared to T1. CONCLUSION: There was a considerable and late increase in the possible SB in adolescents in Brazil during the COVID-19 pandemic.

Tracionamento de incisivo central superior impactado utilizando a tomografia linear como método auxiliar de diagnóstico: relato de caso / Linear computed tomography as auxiliar method for diagnosis and treatment of impacted maxillary central incisor: a clinical case report

A impactação dentária é um distúrbio de erupção e, por conseqüência, um dos problemas ortodônticos observados na rotina clínica. O tratamento usualmente envolve o desafio de procedimentos cirúrgicos, ortodônticos e periodontais. Um bom diagnóstico do caso dependerá do diagnóstico precoce e da avaliação da posição e angulação dentária no alvéolo, dentre outros fatores. A apresentação deste caso clínico relata a importância do dente 21, devido a uma grave dilaceração de raiz, diagnosticada por meio de uma tomografia linear. O tratamento proposto combinou a expansão do arco superior, a técnica cirúrgica e de erupção fechada e a tração ortodôntica, além da aplicação de aparelhagem ortodôntica fixa, para o correto alinhamento do dente. Os procedimentos permitiram restabelecer com sucesso a estética e a oclusão do paciente
