Abstract

The purpose of this study was to evaluate the prevalence of symptoms and signs of temporomandibular joint dysfunction (TMD) and malocclusion in 10-12 year old children and to determine if a relationship exists between symptoms and signs of TMD and malocclusion. The subjects were composed of 465 school children (233 boys and 232 girls). Each subject was evaluated with simplified questionnaire and clinical examination to measure symptoms and signs of TMD and malocclusion. The results showed an elevated prevalence of headache (34.6%), which were more frequent in girls than boys. The most common cardinal sign of TMD was clicking (32.9%), which increased with age. TMJ lateral tenderness was present in 18.1% of the subjects and had a tendency to increase with age. Masseter muscle tenderness was found to be sensitive in 15.1%of the subjects and had a tendency to increase with age. Restriction of mandibular mobilitywas present in 30.3% of the subjects and had a tendency to increase with age. There was no significant difference in the prevalence of TMD signs between sex. The occlusal status showed Class I malocclusion in 73.3%, Class III in 12.9%,Class II division 1 in 11%, Class II division 2 in 2.8%. There was no significant difference in malocclusion traits between sex. There was statistically significant relationship between TMD signs and symptoms and class II division 1 and Class III malocclusion(p<0.05). The results indicate that the prevalence of TMD symptoms and signs in children is high, and the evaluation of TMD in children seems to be important.

본 연구의 목적은 10-12세 성장기 아동에서 측두하악장애의 증상과 징후 및 부정교합의 유병율과 이의 상관관계에 대해 알아보고자 하였다. 연구를 위해 강릉시에 위치한 6개 초등학교의 10-12세 아동 465명(남자 233명, 여자 232명)을 대상으로 간이병력조사와 간이임상검사를 시행하였다. 조사 결과, 측두하악장애 증상 중 두통의 유병율(34.6%)이 가장 높았으며, 여자(40.4%)가 남자(28.8%)보다 유의성 있게 높았다. 그 밖의 측두하악장애 증상은 연령 증가에 따라 혹은 성별에 따라 유의한 차이가 없었다. 측두하악장애 징후 중 단순관절음의 유병율(32.9%)이 가장 높았으며, 연령 증가에 따라 유의한 증가를 보였다. 악관절 촉진시 측방 압통의 유병율은 18.1%이었으며, 연령 증가에 따라 유의한 증가를 보였다. 근육 촉진시 압통에서 교근의 유병율(15.1%)은 전측두근과 후측두근 보다 높았으며, 연령 증가에 따라 유의성 있는 증가를 나타냈다. 개구제한의 유병율은 30.3%를 차지하였으며, 연령 증가에 따라 유의성 있는 증가를 보였다. 모든 측두하악장애 징후의 유병율은 성별에 따른 유의한 차이를 보이지 않았다. Angle's I급 부정교합(73.3%)이 가장 흔하였으며, 다음으로 III급 (12.9%), II급 1류 (11%), II급 2류 (2.8%) 순을 보였다. 각각의 교합상태의 유병율은 성별에 따라 유의성 있는 차이는 없었다. 측두하악장애 증상 및 징후에 관련된 교합상태는 II급 1류와 III급 부정교합이었다 (p<0.05). 본 연구결과는 성장기 아동에서 측두하악장애 증상 및 징후가 높은 유병율을 나타내, 성장기 아동의 측두하악관절 평가가 중요함을 시사한다.
