Abstract

The purpose of this study was to examine the size, form of dental arch and occlusion type in college students in our country and the relationship of the factors. The subjects in this study were 210 selected dental hygiene students. The collected data were analyzed by a statistical package PASW 18.0. When their size, form and occlusion of dental arch were analyzed, the inter-canine width of the maxillary was 34.38 mm, and the inter-first molar width was 52.05 mm. The canine depth was 8.60 mm, and the first molar depth was 28.69 mm. As for the mandibular, the inter-canine width was 26.42 mm, and the inter-first molar width was 44.83 mm. The canine depth was 5.54 mm, and the first molar depth was 24.38 mm. Concerning the form of dental arch, the percentage of normal dental arch in the maxillary stood at 29.0, and that of crowding stood at 60.5. The percentage of spacing stood at 10.5. In the case of the mandibular, the percentage of normal dental arch stood at 29.0; crowding, 55.7; and spacing, 15.2. In relation to occlusion, the percentage of normal occlusion stood at 16.7. As to malocclusion, class I that accounted for 55.7 was most common, and class II and class III respectively accounted for 20.5 and 7.1. When the size of dental arch was compared according to the form and occlusion of it, dental arch was largest (45.95 mm) in size when the form of dental arch in the inter-first molar width of the mandibular was spacing. The size of dental arch was 44.73 mm when its form in the same region was normal, and that was 44.58 mm when its form in the same region was crowding (p=0.032). Regarding the relationship between the form and occlusion of dental arch, crowding was most common when there were class I, II and III of malocclusion both in the maxillary and mandibular.

본 연구는 우리나라 여대생의 치열궁의 크기 및 형태와 교합유형을 조사하고 이들의 관련성을 알아보고자 치위생과 여학생 210명을 대상으로 실시하였다. 수집된 자료는 PASW 18.0 프로그램을 이용하여 통계분석하였으며, 결과는 다음과 같다. 치열궁의 크기 및 형태와 교합을 산술평균 및 빈도를 분석한 결과 상악의 견치 간 폭경은 34.38 mm, 제1대구치 폭경은 52.05 mm였으며, 견치 장경은 8.60 mm, 제1대구치장경은 28.69 mm였다. 하악은 견치 간 폭경이 26.42 mm, 제1대구치 폭경이 44.83 mm였으며, 장경은 견치가 5.54 mm, 제1대구치가 24.38 mm였다. 치열궁의 형태는 상악에서 정상이 29.0%, 협착이 60.5%, 공극이 10.5%였으며, 하악은 정상이 29.0%, 협착이 55.7%, 공극이 15.2%였다. 교합은 정상이 16.7%였으며, I급 부정교합이 55.7%로 가장 많았고, II급은 20.5%, III급은 7.1%였다. 치열궁의 형태와 교합에 따른 치열궁의 크기를 비교한 결과 하악의 제1대구치 폭경이 치열궁의 형태가 공극인 경우에 45.95로 가장 컸으며, 정상이 44.73, 협착이 44.58을 기록하였다(p=0.032). 치열궁 형태와 교합관계는 상 하악 모두 I, II, III급 부정교합에서 협착이 71.8%, 76.7%, 60.0%와 69.2%, 60.5%, 60.0%로 가장 높았다(p<0.001). 이상의 결과를 종합해보면 과거에 비해 여러 원인으로 치열궁의 장 폭경이 줄어들고 있으며, 협착으로 인한 부정교합이 증가하고 있다. 따라서 정기적인 치과검진과 구강악습관의 관리가 필요할 것으로 보인다.
