The aims of this study were to perform an exploratory analysis of probable awake (AB) and sleep bruxism (SB) prevalence using of different diagnosis criteria based on the International Consensus; evaluate the associations between self-report and clinical signs/symptoms in adolescents. Participated in this cross-sectional study 403 adolescents aged 12- to 19-years-old enrolled in public and private schools from Belo Horizonte, Brazil. Parents/caregivers answered a questionnaire about sociodemographic status and adolescents' health status. Adolescents answered a questionnaire evaluating AB (e.g., grinding and clenching) and SB (e.g., grinding, bracing, and thrusting) activities and frequent headaches. A clinical examination was performed on adolescents to evaluate bruxism clinical signs/symptoms (pain upon palpation on masseter and temporal, linea alba, indentation on the tongue and attrition wear severity). Descriptive statistics and Pearson's Qui-square test were performed (P≤0.05). Adolescents mean age was 14.3±1.5 years, and 58.1% were female. Self-report of SB was identified in 31% of participants and self-report of AB in 51.6%. Almost all adolescents (99%) presented at least one tooth with attrition wear (98.5% on enamel and 0.5% on dentin), with a mean number of 12.4±5.7 teeth. Depending on the diagnosis criteria, the prevalence of probable SB and AB varied from 0- 99% and 0.2- 99%, respectively. A high inconsistency was found for the prevalence of probable AB and SB in adolescents, which were influenced by the different clinical sings/symptoms used as diagnosis criteria. Frequent headaches and pain upon palpation on masseter and temporal muscle were associated to self-report of AB and SB among adolescents.
本研究的目的是使用基于国际共识的不同诊断标准对可能的觉醒（AB）和睡眠磨牙症（SB）的患病率进行探索性分析；评估青少年自我报告与临床体征/症状之间的关联。本横断面研究共纳入了 403 名年龄在 12 至 19 岁的青少年，他们来自巴西贝洛奥里藏特的公立和私立学校。家长/照顾者回答了一份关于社会人口统计学状况和青少年健康状况的问卷。青少年回答了一份问卷，评估 AB（例如，磨牙和紧咬牙）和 SB（例如，磨牙、咬牙切齿和推力）活动以及频繁头痛。对青少年进行临床检查以评估磨牙症的临床体征/症状（咀嚼肌和颞肌触诊时疼痛、白线、舌部压痕和磨损程度）。进行了描述性统计和 Pearson's Qui-square 检验（P≤0.05）。青少年的平均年龄为 14.3±1.5 岁，58.1%为女性。参与者中有 31%自我报告有 SB，51.6%自我报告有 AB。几乎所有青少年（99%）至少有一颗牙齿有磨损（98.5%在牙釉质上，0.5%在牙本质上），平均有 12.4±5.7 颗牙齿。根据诊断标准，可能的 SB 和 AB 的患病率差异很大，分别为 0-99%和 0.2-99%。青少年中可能的 AB 和 SB 的患病率存在高度不一致性，这受到不同的临床体征/症状作为诊断标准的影响。频繁头痛和咀嚼肌及颞肌触诊时疼痛与青少年的 AB 和 SB 自我报告有关。
