초록
입술은 사람의 인상을 결정하는 중요한 부분중의 하나이다. 본 연구는 두부계측방사선사진을 이용하여 구호흡자와 비호흡자의 입술두께를 비교하여 구호흡과 하순 두께 변화와의 연관성을 알아보았다. 8세~18세인 아동 및 청소년 436명을 대상으로 두부방사선계측사진을 조사하였다. 전체 조사대상자를 구호흡 그룹과 비호흡 그룹으로만 나누어서 평균과 표준편차를 구한 결과 구호흡 그룹의 하순/상순 비율은 1.13±0.14, 비호흡 그룹의 하순/상순 비율은 1.02±0.14로 나타났다. Skeletal class에 따라 구분한 그룹의 각각의 평균과 표준편차를 살펴보면 skeletal class I은 1.05±0.09, skeletal class II는 1.20±0.12, skeletal class III는 0.97±0.11로 나타났다. 호흡양상에 따라 비교하였을 때 비호흡을 하는 그룹보다 구호흡을 하는 그룹에서 하순/상순 비율이 더 큰 값을 나타내어 하순의 두께가 더 두꺼운 양상을 보였다. Skeletal class에 따라서 비교하였을 때는 skeletal class II 그룹에서 하순/상순 비율이 가장 큰 값을 나타내어 하순의 두께가 가장 두꺼운 양상을 보였다
Abstract
As attractive lips are important component of appealing faces, the study was conducted to investigate the association of mouth-breathing and thickness of lower lips in mouth-breathers and nasal-breathers. The subjects were 436 adolescent patients aged 8 ~ 18 years who took cephalometrics. The results were as follows. The ratio of lower lip thickness to that of upper lip thickness in mouth breathing and nasal breathing groups were 1.13±0.14, 1.02±0.14,respectively. According to subjects skeletal pattern, the ratio in Class I sample was 1.05±0.09. Class II subjects showed 1.20±0.12, and Class III showed 0.97±0.11. Mouth - breathers had higher lower / upper lip ratio than nasal breathers meaning their lower lips were thicker. Skeletal Class II patients group showed the most thickest lower lips among Class I, II, III subgroups.
