초록

최대개구량은 측두하악관절과 저작계의 임상 기능 평가에 유용한 진단 도구이다. 이 연구는 한국 유치열기 어린이의 정상최대개구량을 측정하고 관련 인자들 간의 상관관계를 조사함으로써, 소아 악관절 장애의 진단 및 치과치료시 안전한 개구 범위 정립에 기여할 수 있는 기초 자료를 마련하고자 하였다. 악관절장애가 없는 건강한 어린이(만2-6세) 151명을 대상으로 최대개구량을 측정하고, 성별, 연령, 신장, 체중과 입의 너비를 기록하였다. 평균 최대개구량은 37.72 ± 5.10 mm였고 성별에 따른 유의한 차이는 없었으나, 연령, 신장, 체중, 입의너비 증가에 따라서는 유의하게 증가하였다(p < 0.05). 최대개구량과 관련 요인들 간의 상관관계 분석 결과, 신장에서 가장높은 상관관계가 관찰되었다. 결론적으로 한국 유치열기 어린이의 정상 최대개구량에 관한 자료를 얻을 수 있었고, 이 연구는 소아 악관절장애의 진단및 안전 개구 범위에 관한 기초 지식을 제공할 수 있을 것이다.

Abstract

Maximum mouth opening is regarded as an important tool used to evaluate the clinical function of temporomandibular joint and the masticatory system. It has been reported that children can also exhibit severe dysfunction or pain in some cases of temporomandibular disorder. The purpose of this study was to measure the normal maximum mouth opening in Korean children and to analyze the correlations between mouth opening and the associated factors. Maximum mouth opening was measured from 151 healthy children between the ages of 2 and 6 years old. Age, height, weight, and mouth width were also recorded. As a result, the mean maximum mouth-opening was 37.72 ± 5.10 mm. While the values were greater in boys than in girls without statistical significance, the increases of maximum mouth opening based on age, height, weight, and mouth width were significant (p < 0.05). In children, positive correlation coefficients were observed between maximum mouth opening and the associated factors and height showed the highest correlation. In conclusion, we collected data of the normal range of maximum mouth opening in Korean children, and this study can be utilized as a basis in diagnosing pediatric temporomandibular disorder and safety standard of mouth opening during dental procedures.
