背景:布鲁克斯病是一种在个人生活中具有多种后果的行为,尤其是在童年开始的时候。然而,磨牙症可能是一个潜在的保护因素,这是一种减少负面健康结果机会的属性。
目的:评估儿童和青少年睡眠磨牙症(SB)和牙齿磨损的发生率。
方法:这项纵向研究始于2014年和2016年(基线),最初的1816名儿童随访5年和3年。分别。后续数据收集工作于2019年开始。由于每个阶段的年龄组,SB的诊断是父母报告(基线)和自我报告(随访),并收集与SB症状相关的问题。五个校准的检查者(κ>0.7)收集临床数据。临床变量是牙齿侵蚀和牙齿磨损。上下文,个人,收集行为和临床特征。使用多水平逻辑回归模型来调查上下文,个人,与SB的行为和临床特征。对重复测量进行泊松回归以评估SB和牙齿磨损的发生率(发生率比率-IRR和置信区间-95%CI)。
结果:二百五十三名儿童和青少年回答了问卷并接受了临床检查。2019年随访的平均年龄为11.25岁(±2.19)。SB的发生率没有增加(95%CI:0.74-1.35)。儿童/青少年的牙齿佩戴风险高2.2(95%CI:1.89-2.60)。随访中的SB与上下文变量相关联,耳痛,侵蚀和清醒磨牙症。
结论:在这个人群中,患有SB的儿童仍然具有这种行为,并且多年来表现出较高的牙齿磨损。
BACKGROUND: Bruxism is a behaviour that has several consequences in an individual\'s life, especially when it starts in childhood. However, bruxism can be a potential protective factor, which is an attribute that reduces the chance of a negative health outcome.
OBJECTIVE: To evaluate the incidence of sleep bruxism (SB) and dental wear in children and adolescents.
METHODS: This longitudinal study began in 2014 and 2016 (baseline) with initial 1816 children followed for 5 and 3 years, respectively. The follow-up data collection started in 2019. The diagnosis of SB was parents report (baseline) and self-report (follow-up) due to age groups of each phase, and questions related to symptoms of SB were collected. Five calibrated examiners (kappa >0.7) collected the clinical data. The clinical variables were dental erosion and dental wear. Contextual, individual, behaviour and clinical characteristics were collected. A multilevel logistic regression model was used to investigate the association of contextual, individual, behaviour and clinical characteristics with SB. Poisson regression for repeated measures was performed to evaluate the incidence of SB and dental wear (incidence rate ratio-IRR and confidence interval-95% CI).
RESULTS: Two hundred and fifty-three children and adolescents answered questionnaires and were clinically examined. The mean age of the follow-up in 2019 was 11.25 years old (±2.19). There was no increase in the incidence of SB (95% CI: 0.74-1.35). Children/adolescents had a 2.2 higher risk to present dental wear (95% CI: 1.89-2.60). SB at the follow-up was associated with the contextual variable, earache, erosion and awake bruxism.
CONCLUSIONS: In this population, children with SB remained with this behaviour and showed higher dental wear over the years.
