青年顳顎功能障礙之盛行率與咬合、心理人格特質之相關性

The Prevalence of Temporomandibular Disorder and Its Relation to Occlusal Factors, Psychological Stress and Personality in Youths

摘要


一般認為異常咬合以及心理壓力是引起顳顎功能障礙的兩項主要因素。本研究將探討顳顎功能障礙在青年人中的盛行率,以及與異常咬合、心理壓力人格的相關性。針對南部地區義守大學802名新生進行臨床檢查與問卷調查。口內的檢查包含牙周組識,齒列的擁擠程度,水平覆蓋(overjet),垂直覆蓋(overbite),中線,咬合分類及牙齒磨耗程度等。問卷題目包含,1.CESD憂鬱量表。2.TMD相關症狀問題。本研究顳示盛行率達72.8%。其中男性的盛行率69.6%,遠低於女性的盛行率78.0%,達統計學上的顳著差異(p=0.0093)。從咬合因素來看,中線偏移與顳顎功能障礙具有顳著相關(p=0.0115)。在心理因素方面,隨著憂鬱程度的提高,具有TMD症狀的比例也逐步上升,統計上呈現顳著的相關性(p=0.0002)。

It is considered that persons exposed to malocclusion and stress are under increased risk of the occurance and progression of Temporo-mandibular disorders (TMD). The aim of this study was to evaluate the prevalence of signs and symptoms of TMD in youths, and the relationship among malocclusion, psychological stress, personality and TMD. There were 802 subjects aged from 17 to 22 years old. The oral examination consisted of inspection, palpation, evaluation of occlusion type, overbite, overjet, crowding, midline, periodontal condition, bruxism condition, articular sound. The content of questionnaire was designed to evaluate the degree of TMD, psychological factors (degree of depression) in the volunteers of this study. In the examined population of 802 students, the prevalence of TMD was 72.8% (584 subjects). Statistical analysis show a significant higher prevalence of female in TMD group (P=0.0093). In the examination of occlusal factors, some type of malocclusion seemed to be associated with TMD. For example, in midline deviation evaluation, the association was statistically significant (p=0.0115). In the examination of psychological factors, the chi-square test revealed that depression (tested by CES-D) and TMD were statistically significantly associated (p=0.0002).
