Abstract

Background: Mandibular instability during primary tooth eruption has been suggested as a factor associated with parent-reported awake bruxism (PRAB) in early childhood, but this relationship remains unclear.

Objective: To evaluate the association between PRAB frequency and the number of erupted primary teeth by dental groups, as well as signs and symptoms of tooth eruption, oral habits, and sociodemographic characteristics.

Methods: This cross-sectional study included 144 Brazilian children aged 4-36 months. Parents/caregivers completed an interview-based questionnaire covering sociodemographic characteristics, oral habits, signs and symptoms of tooth eruption, and PRAB frequency. A single-trained dentist performed oral examinations to record erupted primary teeth. Descriptive analysis, chi-square, and Kruskal-Wallis tests were conducted (p < 0.05).

Results: The prevalence of PRAB was 16.7%. No significant association was found between PRAB frequency and sex, age, oral habits, or signs and symptoms of tooth eruption. However, more erupted primary molars (p = 0.038) and canines (p = 0.022) were associated with a lower PRAB frequency.

Conclusion: The number of erupted primary molars and canines was associated with the frequency of PRAB in early childhood, supporting the hypothesis that AB during this stage may represent an adaptive behaviour.

幼儿期父母报告的醒着磨牙与牙齿萌出的关系。

背景：乳牙萌出期间的下颌不稳定被认为是儿童早期父母报告的清醒磨牙症（PRAB）的一个因素，但这种关系尚不清楚。目的：探讨PRAB频率与各牙组乳牙萌牙数量、萌牙体征、症状、口腔习惯、社会人口学特征之间的关系。方法：本横断面研究纳入144名4-36个月的巴西儿童。家长/照顾者完成了一份基于访谈的问卷，内容包括社会人口统计学特征、口腔习惯、出牙的体征和症状以及PRAB频率。一名受过单一训练的牙医进行口腔检查，记录乳牙的爆发情况。进行描述性分析、卡方检验和Kruskal-Wallis检验(p)。结果：PRAB患病率为16.7%。PRAB频率与性别、年龄、口腔习惯或牙齿萌出的体征和症状之间没有明显的关联。然而，更多的乳牙（p = 0.038）和犬齿（p = 0.022）与较低的PRAB频率相关。结论：乳牙和犬齿的爆发数量与儿童早期发生PRAB的频率有关，支持了这一阶段的AB可能代表一种适应行为的假设。

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
