ABSTRACT Objective: To assess the influence of perceived stress during the COVID-19 pandemic over awake bruxism (AB) and sleep bruxism (SB). Material and Methods: Observational web-based research carried out in a state in the Brazilian Northeast. The sample was composed of dental students from seven faculties, divided into three groups: beginning (1-4 semesters), middle (5-7), and end (8-10). An online questionnaire was constructed: Socio-demographic, Perceived Stress Scale (PSS-10), Self-reported AB and SB, and COVID-19 Fear Scale. Data were collected from April to June 2021 by sending the questionnaire through WhatsApp®, e-mail, and Instagram®. After bivariate analyses, a multiple logistic regression model was performed to discriminate variables for perceived stress and AB and SB. Hosmer and Lemeshow and chi-square tests were used to check the model's goodness of fit. Results: A total of 391 dental students participated in this research - most women (69.8%), unmarried (69.8%), family income less than three minimum wages (60.9%), self-reported physical activity (63.3%). Perceived stress was low to moderate (72.1%), SB was 39.6%, AB was 49.6%, and low COVID-19 fear was 81.1%. COVID-19 fear (3.03), being female (2.47), and using psychotropic (2.53) increases the chance of being stressed. Perceived stress can predict AB in models 1 (p=0.008) and 4 (p=0.039). There was no significance for perceived stress and SB. Conclusion: Perceived stress during the COVID-19 pandemic influenced awake bruxism. Objective COVID19 COVID 19 COVID-1 (AB .

Introduction: The COVID-19 pandemic brought changes in all segments of society, including with impact on dental education. Objective: To evaluate the fear of COVID-19 in dental students. Methodology: Cross-sectional study composed of 40 dental students from a private university. Data were collected regarding sociodemographic issues and the Fear of COVID-19 Scale (FCV-19S) was applied. The data were tabulated using the IBM SPSS software and analyzed descriptively (absolute and percentage frequencies, measures of central tendency and variability). Results: Most students were female (60.0%), between 16 and 20 years old (50.0%) and 45.0% had a monthly family income of more than one and less than three minimum wages. The average of the total score on the FCV-19S was 18.45 (SD = 6.08), with a minimum score of 7 and a maximum of 30. Most students showed “little fear” of COVID-19 (55.0 %). The items “I am very afraid of COVID-19”, “I am afraid of dying because of COVID-19”, and “I get nervous or anxious when I see news in the newspapers and on social media about COVID-19” obtained the highest average values. Conclusion: Most students showed little fear of COVID-19, despite the items “I am very afraid of COVID-19”, “I am afraid of dying because of COVID-19” and “I get nervous or anxious when I see news in newspapers and social media about COVID-19” having obtained the highest average values.

Introdução: A pandemia da COVID-19 acarretou mudanças em todos os segmentos da sociedade, inclusive com impacto na educação odontológica. Objetivo: Avaliar o medo frente à COVID-19 em estudantes de Odontologia. Metodologia: Estudo transversal composto por 40 estudantes de Odontologia de uma universidade privada. Foram coletados dados referentes a questões sociodemográficas e aplicada a Escala de Medo da COVID-19 (EMC-19). Os dados foram tabulados utilizando-se o software IBM SPSS e analisados descritivamente (frequências absoluta e percentual, medidas de tendência central e de variabilidade). Resultados: A maioria dos estudantes era do sexo feminino (60,0%), tinha entre 16 e 20 anos (50,0%) e 45,0% possuía renda familiar mensal de mais de um e menos de três salários mínimos. A média do escore total na EMC-19 foi de 18,45 (DP = 6,08), com escore mínimo de 7 e máximo de 30. A maior parte dos estudantes apresentou “pouco medo” da COVID-19 (55,0%). Os itens “Eu tenho muito medo da COVID-19”, “Eu tenho medo de morrer por causa da COVID-19”, e “Eu fico nervoso ou ansioso quando vejo notícias nos jornais e nas redes sociais sobre a COVID-19” obtiveram os maiores valores médios. Conclusão: A maioria dos estudantes apresentou pouco medo da COVID-19, apesar dos itens “Eu tenho muito medo da COVID-19”, “Eu tenho medo de morrer por causa da COVID-19” e “Eu fico nervoso ou ansioso quando vejo notícias nos jornais e nas redes sociais sobre a COVID-19” terem obtido os maiores valores médios.
