Psychological and financial impact of the COVID-19 pandemic during the first stages of the pandemic: Brazilian orthodontists´ perspective.

INTRODUCTION: Brazil faced a catastrophic situation in the coronavirus pandemic. Due to the high risk of contamination and spread of COVID-19, dentist have been attending only urgency and emergency services in Brazil at the beginning of the pandemic. OBJECTIVE: This research aimed to evaluate the psychological and financial impacts caused by the coronavirus pandemic in Brazilian orthodontists. METHODS: This population-based cross-sectional study collected demographic data and mental health measurements from 404 orthodontists. Depression, anxiety, insomnia, and distress were evaluated through Brazilian versions of the 9-item Patient Health Questionnaire (9-PHQ), the 7-item Generalized Anxiety Disorder scale and Mini-Tracking (GAD), the 7-item Insomnia Severity Index (ISI), and the 22-item Impact of Event Scale-Revised (IES-R), respectively. The demographic data of the sample was described using descriptive statistics. The data was analyzed according to sex, professional status, and economic income. Comparisons were performed using Chi-square tests, Mann-Whitney U tests, and Kruskal-Wallis followed by post-hoc tests. RESULTS: Females, graduate students, and lower incomes subgroups showed higher levels of depression, anxiety, insomnia, and distress. Most orthodontists showed moderate to extreme financial and professional concerns during the pandemic. CONCLUSION: The coronavirus pandemic negatively affected the psychological health and increased the financial concerns of the Brazilian orthodontists, mainly female, graduate students, and with income below 10k participants.

RESUMO Introdução: O Brasil enfrentou uma situação catastrófica durante a pandemia do coronavírus. Devido ao alto risco de contaminação e disseminação do vírus da COVID-19, os cirurgiões-dentistas passaram a realizar apenas atendimentos de urgência ou emergência no início da pandemia. Objetivo: O presente estudo teve como objetivo avaliar o impacto financeiro e psicológico causado pela pandemia do coronavírus nos ortodontistas brasileiros. Métodos: Este estudo transversal de base populacional coletou os dados demográficos e o impacto da pandemia em 404 ortodontistas. Depressão, ansiedade, insônia e angústia foram avaliadas, respectivamente, por meio da versão em português do Questionário de Saúde do Paciente (PHQ-9), do módulo de transtorno de ansiedade generalizada (GAD) do Mini-Tracking (GAD/Mini-Tracking), do Índice de Severidade de Insônia (ISI) e o do Impact of Events Scale-Revised (IES-R). As características demográficas da amostra foram apresentadas por meio de estatística descritiva. Os dados foram analisados de acordo com o sexo, situação profissional e renda econômica. As comparações foram realizadas utilizando os testes de Qui-quadrado, Mann-Whitney U e Kruskal-Wallis, seguidos de testes post-hoc (p<0,05). Resultados: Mulheres, estudantes de pós-graduação e profissionais com menores rendas apresentaram níveis mais altos de depressão, ansiedade, insônia e angústia. A maioria dos ortodontistas mostrou preocupação financeira e profissional moderada a extrema durante a pandemia. Conclusão: A pandemia do coronavírus afetou negativamente a saúde psicológica dos ortodontistas brasileiros e aumentou as preocupações financeiras desses profissionais. As mulheres, os estudantes de pós-graduação e os participantes com renda mensal menor que R$10 mil foram os grupos mais afetados.

Effects of Class II elastics in the treatment of Class II malocclusion / Alterações dentoalveolares e esqueléticas consequentes ao uso de elásticos para tratamento da má-oclusão de Classe II

Introduction: The objective of this study was to compare the effects of Class II malocclusion correction with Class II elastics with those produced by Class II malocclusion correction with extraoral headgear associated with multibracket appliances. Methods: A sample of 53 patients with Class II malocclusion was divided into two groups. The elastic group (EG) consisted of 26 patients who were treated with fixed appliances associated with Class II elastics. The control group (CG), consisted of 27 patients treated with fixed appliances and extraoral headgear. The groups were matched regarding initial age, treatment time, initial severity of Class II molar relationship and sex distribution. Pre- and posttreatment lateral cephalometric radiographs were evaluated. T tests were performed to compare the initial status and the treatment changes of the groups. Results: There was occlusal plane clockwise rotation in the EG. The maxillary incisors presented greater palatal tipping and retrusion and the mandibular incisor experienced smaller extrusion in the elastic than in the control group. Conclusion: Despite these small differences in treatment effects, they cannot be considered generally clinically unfavorable in every situation. (AU)

Introdução: O objetivo deste trabalho foi comparar as alterações resultantes do tratamento da má-oclusão de Classe II com o uso de elásticos intermaxilares de Classe II com as alterações resultantes do tratamento do mesmo tipo de má-oclusão com o uso do aparelho fixo associado ao aparelho extrabucal. Métodos: Uma amostra composta de 53 pacientes com má-oclusão de Classe II foi dividida em dois grupos. O Grupo Elástico (GE) foi composto por 26 pacientes tratados com aparelho fixo associado aos elásticos de Classe II. O Grupo Controle (GC) foi composto por 27 pacientes tratados com aparelho fixo associado ao aparelho extrabucal. Os grupos foram compatibilizados de acordo com a idade inicial, o tempo de tratamento, a severidade da má-oclusão de Classe II inicial e a distribuição por sexos. Telerradiografias laterais iniciais e finais do tratamento foram avaliadas. O teste t foi utilizado para comparar a condição inicial e as alterações do tratamento dos grupos. Resultados: Ocorreu uma rotação horária do plano oclusal no GE. Os incisivos superiores apresentaram uma maior inclinação palatina e maior retrusão, e os incisivos inferiores mostraram uma menor extrusão no GE que no GC. Conclusão: Apesar das pequenas diferenças nos efeitos dos tratamentos, eles não podem ser geralmente considerados como clinicamente desfavoráveis em todas as situações. (AU)

Is the presence of Simonart's band in patients with complete unilateral cleft lip and palate associated with the prevalence of missing maxillary lateral incisors?

INTRODUCTION: The aim of this study was to compare the prevalence of agenesis of the maxillary lateral incisors in the cleft area of patients with unilateral cleft lip and palate with and without Simonart's band. METHODS: A sample of panoramic radiographs of 121 patients with a mean age of 7 years was divided into 2 groups: group 1 included 60 patients with Simonart's band, and group 2 included 61 patients without Simonart's band. Patients with syndromes were not included. Chi-square tests were used for intergroup comparisons (P <0.05). RESULTS: In the pooled subgroup, the prevalences of maxillary lateral incisor agenesis, supernumerary maxillary lateral incisors, 1 maxillary lateral incisor mesial to the cleft, and 1 maxillary lateral incisor distal to the cleft were 40.5%, 12.5%, 8.2%, and 38.8%, respectively. In group 1, these frequencies were 35%, 10%, 6.7%, and 48.3%; in group 2, they were 45.9%, 13.1%, 11.5%, and 29.5%. There was a statistically significant difference between the groups for the prevalence of a maxillary lateral incisor distal to the cleft. CONCLUSIONS: The presence of Simonart's band is associated with a higher frequency of maxillary lateral incisor development in the maxillary process.
