Abstract

The purpose of this study was to examine the relationship between the physique of 147 dental hygiene students and the size of their dental arch. A survey was conducted, and impression taking was carried out at the same time to measure the arch length and width of the students. The findings of the study were as follows: 1. 74.8 percent of the students got a dental checkup over the past year. 86.4 percent breathed through the nose. 18.4 percent had ever received orthodontic treatment, and 49.7 percent had ever had their tooth extracted. 94.6 percent were fond of refined food, and 52.4 percent had a liking for hard food. 2. There were no statistically significant differences in arch length and width according to all the variables that related the size of dental arch. 3. Out of the physique variables, weight was identified as a variable to make a statistically significant difference to arch length and width. A heavier weight led to larger mandibular inter-canine width and larger maxillary inter-molar width. 4, A heavier weight had a weaker positive correlation to inter-canine width and inter-molar width. Arch length and width were most closely linked to maxillary inter-molar width and mandibular inter-molar width. The above-mentioned findings show that weight exerted an influence on the form of dental arch among the physique variables. In the future, sustained research efforts should be made to keep track of the relationship between the change of physique and the change of dental arch to improve the stability of occlusion and promote oral health.

본 연구는 치위생과 학생 147명을 대상으로 체격에 따른 치열궁 크기의 관련성을 조사하고자 실시하였다. 연구를 위해 설문지 작성과 치열궁 장 폭경 계측을 위한 인상채득이 동시에 실시되었으며, 다음과 같은 결론을 얻었다. 1. 1년 이내에 구강검진 경험이 있는 경우는 74.8%, 코로 숨을 쉬는 경우는 86.4%, 교정과 발치경험이 있는 경우는 각각 18.4%, 49.7%로 조사되었다. 정제된 음식은 94.6%가 좋아한다고 응답하였으며, 단단한 음식은 52.4%가 좋아한다고 응답하였다. 2. 치열궁 크기의 관련 요인에 따른 치열궁 장 폭경은 모든 변수가 통계적으로 유의한 차이를 보이지는 못했다. 3. 체격에 따른 치열궁 장 폭경 중 통계적으로 유의한 차이를 나타낸 변수는 신장과 체중이었으며, 신장이 클수록 상악 치열궁 장경이 크게, 체중이 많이 나갈수록 하악 견치간 폭경과 상악 구치간 폭경도 큰 것으로 나타났다. 4. 체중이 많이 나갈수록 상, 하악 견치간 폭경과 상, 하악 구치간 폭경이 약한 양의 상관관계를 보였으며, 상하악 치열궁 장경과 견치간 폭경, 구치간 폭경에서는 상악 구치간폭경과 하악 구치간 폭경이 가장 높은 관련성을 보였다. 이상의 결과로 보아 체격요건 중 체중이 치열궁 형태에 영향을 주었다. 앞으로도 체격변화에 따른 치열궁의 변화를 지속적으로 조사함으로써 안정적인 교합과 구강건강을 위한 자료로 활용할 수 있도록 해야 할 것이다.
