Abstract

Abnormal orofacial functions such as lip incompetency in the period of growth and development can cause morphological anomalies of the craniofacial complex. Therefore, it is crucial to make an early diagnosis based on the evaluation of the myofunctional conditions, and to make appropriate treatment plans. The objectives of this study were to quantitatively evaluate the standard lip closing force (LCF) of each age in the elementary school children, and to evaluate the relationships between LCF and affecting factors. The sample consisted of 765 children who were 7 - 12 years old in Jeonju city. Clinical examination about occlusal conditions and lip competency, and LCF measurement were performed by a single examiner. LCF was measured three times for each children with the LCF measuring device. The LCF was correlated positively with age in both sexes. The distribution of LCF groups was correlated significantly with Angle's classes and lip competency (p = 0.016, 0.004). The proportion of children with high LCFs was greater in the "competent lip" group, whereas the proportion of those with low LCFs was greater in the "incompetent lip" group.

성장기 어린이에게서 나타나는 구순폐쇄 부전은 구강기능 및 구강 주위 조직의 구조적 발달 이상을 초래하게 되며, 이는 구강안면 근기능 이상으로 발전된다. 이처럼 입술을 다무는 것은 필수적이고 중요한 행동이므로, 입술을 다무는 힘을 측정하는 것은 구강 감각 및 운동 이상이 있는 환자를 평가함에 있어서 매우 유용할 수 있다. 이 연구의 목적은 학령기 어린이의 연령, 성별에 따른 평균 구순폐쇄력을 측정하고, 이에 영향을 주는 요인들과의 상관성을 분석하는 것이다. 전주시에 소재한 초등학교 5곳의 7 - 12 세 어린이 765명을 대상으로, 교합상태, 구순폐쇄 여부에 대한 임상 검사와 구순폐쇄력 측정을 시행하였다. 구순폐쇄력은 3회 측정하였고, 측정값의 평균을 대상자의 구순폐쇄력으로 활용하였다. Angle 분류법 및 안정시 구순폐쇄 여부는 구순폐쇄력 고저군 분포와 통계적으로 유의한 상관관계를 나타냈다(p = 0.016, 0.004). 완전 구순폐쇄 군에서는 높은 구순폐쇄력 군의 비율이 높았던 반면, 불완전 구순폐쇄 군에서는 낮은 구순폐쇄력 군의 비율이 더 높게 나타났다.
