Abstract

For the purpose of evaluating the prevalence of malocclusion and self-esteem in adolescents, 1,380 middle-school students in the Yangsan area were surveyed by oral examination and questionnaires and the obtained results were as follows: The distribution of 1st molar occlusion by Angle's classification was 69.0, 19.4, 10.6% for Class I, II and III respectively. In the horizontal relationship, the prevalence of normal overjet and crossbite was 86.9% and 5.6% respectively whereas larger and extremely larger overjet was found in 6.6% and 0.8%. In the vertical relationship of anterior teeth, normal, deep overbite and openbite was shown in 94.1%, 4.7%, and 1.2%. For the midline discrepancy, the distribution of groups with 0~1 mm, 2~4 mm and over 5 mm was 98.2%, 1.4%, and 0.4%. Crowding only in the maxilla was found in 9.6%, while that only in the mandible and in both arches was 14.1% and 24.1% respectively. Spacing only in the maxilla was seen in 3.0%, while that only in the mandible and in both arches was 2.4% and 1.7% respectively. Significant difference in self-esteem was revealed in female and malocclusion groups of crossbite and openbite(p < 0.05).

본 연구는 청소년을 대상으로 부정교합 요소들의 유병률을 조사하고 각 요소와 자존감의 연관성을 평가할 목적으로 시행되었다. 양산시 소재 3개 중학교에 재학 중인 1,380명을 대상으로 부정교합 요소별 유병률과 자존감 상태를 조사 분석하여 다음과 같은 결과를 얻었다. Angle 분류에 의한 제1대구치 관계는 I, II 및 III급 교합이 각각 69.0%, 19.4%, 10.6%로 나타났다. 수평피개는 정상 86.9%, 반대교합 5.6%, 큰 수평피개 6.6%, 극심히 큰 수평피개 0.8%로 나타났다. 수직피개는 정상 94.1%, 과개교합 4.7%, 개방교합 1.2%였다. 정중선 불일치는 0~1 mm는 98.2%, 2~4 mm는 1.4%, 5 mm 이상은 0.4%였다. 총생은 상, 하악에 총생이 있는 경우가 각각 9.6%, 14.1%, 양악 모두의 경우가 24.1%였으며, 치간공극은 상, 하악에만 있는 경우가 각각 3.0%, 2.4%, 양악 모두의 경우는 1.7%였다. 부정교합 요소별 자존감의 차이는 여자의 경우, 반대교합과 개방교합 그룹에서 자존감 지수가 낮은 값을 보였다(p < 0.05).
