To evaluate the immediate and late impact of the COVID-19 pandemic on the occurrence of possible sleep bruxism (SB) among adolescents in Brazil.
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.
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.
There was a considerable and late increase in the possible SB in adolescents in Brazil during the COVID-19 pandemic.
评估 COVID-19 大流行对巴西青少年中可能发生的睡眠磨牙症（SB）的即时和后期影响。
这是一项在巴西南部青少年（11-15 岁）中进行的纵向研究。在巴西 COVID-19 爆发之前（T1）收集基线数据。之后，在巴西 COVID-19 爆发后 3（T2）和 15 个月时收集数据。可能的 SB 通过以下问题进行评估：“您在睡眠时磨牙吗？”。还收集了社会人口学、心理社会和临床变量。通过重复测量的多级逻辑回归模型评估 SB 的变化。
在 T1 评估的 290 名青少年中，有 182 名在两次随访中均进行了评估。T1 时可能发生 SB 的患病率为 13%，T2 时为 11%，T3 时为 22%。COVID-19 大流行对可能发生的 SB 的发生没有即时影响（T2）。与 T1 相比，COVID-19 大流行 15 个月（T3）后青少年发生可能的 SB 的几率增加了 2.77 倍。
在 COVID-19 大流行期间，巴西青少年中可能发生的 SB 显著增加且呈后期趋势。
