Abstract：
BACKGROUND: To evaluate whether the prevalence of traumatic dental injuries (TDIs) in permanent anterior teeth among school children is associated with sleep behaviours and disorders.
METHODS: A cross-sectional study was carried out with a representative sample of schoolchildren aged 8 to 10 years (n = 1402) from Florianopolis, Brazil. Clinical examinations for TDIs were performed according to the classification proposed by Andreasen. Parents/caregivers completed a questionnaire addressing sociodemographic characteristics and sleep behaviours/disorders (sleep duration, insomnia, sleep rhythmic movement, snoring, and signs of sleep apnoea). Descriptive analysis and Poisson regression were performed.
RESULTS: The prevalence of TDIs was 10.9%. Insomnia was observed in 3.0% of the children, snoring in 42.8%, sleep rhythmic movement in 27.9%, and signs of obstructive sleep apnoea in 33.6% of the schoolchildren. Most children (75.2%) slept less than eight hours a day. The prevalence of TDIs was higher among schoolchildren with an increased overjet (PR: 1.65; 95% CI: 1.15-2.35; P < 0.01), after adjusting for monthly family income, caregiver\'s schooling, and sleep behaviours. The prevalence of TDIs was not associated with sleep behaviours/disorders.
CONCLUSIONS: Parent-reported sleep disorders such as insomnia, sleep rhythmic movement, snoring and signs of sleep apnoea were not associated with the prevalence of TDIs in schoolchildren. © 2024 Australian Dental Association.

摘要：
背景：评估学龄儿童恒牙前牙创伤性牙损伤（TDI）的患病率是否与睡眠行为和障碍有关。
方法：对来自Florianopolis的8至10岁（n=1402）的代表性学童进行了横断面研究，巴西。根据Andreasen提出的分类进行TDI的临床检查。父母/护理人员填写了一份涉及社会人口统计学特征和睡眠行为/障碍的问卷(睡眠持续时间，失眠,睡眠有节奏的运动，打鼾,和睡眠呼吸暂停的迹象)。进行描述性分析和泊松回归。
结果：TDI的患病率为10.9%。在3.0％的儿童中观察到失眠，打鼾占42.8%，睡眠有节奏的运动占27.9%,33.6%的学童出现阻塞性睡眠呼吸暂停的迹象。大多数儿童（75.2%）每天睡眠不足8小时。在过度喷射增加的学童中，TDI的患病率较高（PR：1.65；95％CI：1.15-2.35；P<0.01），调整家庭月收入后，照顾者的学校教育，和睡眠行为。TDI的患病率与睡眠行为/障碍无关。
结论：家长报告的睡眠障碍，如失眠，睡眠有节奏的运动，打鼾和睡眠呼吸暂停的迹象与学童TDI的患病率无关。©2024澳大利亚牙科协会。
