The aim of this study was to investigate the association between symptoms of temporomandibular disorders (TMD), quality of life, and malocclusion.
A cross-sectional observational design study was utilized among 248 schoolchildren aged 12 years old. Symptoms of TMD were assessed using the Orofacial Pain and Temporomandibular Disorders Triage Questionnaire, and subjects were further evaluated as oral-health-related quality of life (CPQ), tooth clenching/grinding and malocclusion (Dental Aesthetic Index). Chi-square for independence, Odds Ratio and Mann-Whitney test were used (p = 0.05) statistically.
Statistically, association was detected between TMD symptoms with pain and worse quality of life (p < 0.0138), and pain with quality of life and clenching/grinding (p = 0.0120 and 0.0007).
The symptoms of TMD are associated with pain and teeth clenching, causing a negative impact on schoolchildren's quality of life; thus, a study of the TMD impact on quality of life is justified.
本研究旨在调查颞下颌关节紊乱病（TMD）症状、生活质量和错牙合之间的关联。
对248名12岁学童进行了一项横断面观察性设计研究。使用口面部疼痛和颞下颌关节紊乱病分诊问卷评估TMD症状，并进一步评估受试者的口腔健康相关生活质量（儿童口腔健康影响程度问卷）、紧咬牙/磨牙情况和错牙合（牙齿美学指数）。采用独立性卡方检验、优势比和曼-惠特尼检验进行统计学分析（p = 0.05）。
在统计学上，TMD疼痛症状与较差的生活质量之间存在关联（p < 0.0138），疼痛与生活质量以及紧咬牙/磨牙之间也存在关联（p = 0.0120和0.0007）。
TMD症状与疼痛和紧咬牙有关，对学童的生活质量产生负面影响；因此，研究TMD对生活质量的影响是有必要的。
