Abstract

The goal of this study was to analyze prevalence and distribution of congenitally missing teeth in 3302 patients from 7 to 15 years old, who had visited and taken panoramic radiographs at the Department of Pediatric Dentistry, from January 2008 to December 2012. The prevalence of hypodontia in the males (5.9%) was slightly higher than in the females (4.7%). In the affected patients, the mean number of congenitally missing teeth in the mandible was statistically higher than in the maxilla (p < 0.05). However, there was no significant difference in the number of congenitally missing teeth between left and right dentitions (p > 0.05). Excluding the Mn. third molars, the most frequent congenitally missing teeth site was the Mn. second premolars. In contrast, the most infrequent congenitally missing teeth sites were the Mx. and Mn. first premolars, and Mx. central incisors. The bilateral combination or antagonistic quadrants combination of congenitally missing teeth in hypodontia patients was 80.3%. The result of this study will contribute to clinicians to make accurate diagnosis and establish favorable treatment plans, by offering invaluable data about the number and distribution of congenitally missing teeth.

이 연구는 2008년 1월부터 2012년 12월까지 소아치과에 내원한 7~15세 사이 아동 중, 파노라마방사선사진을 촬영한 3302명을 대상으로 하여 치아결손증의 유병률 및 선천적 결손치의 분포에 대해 분석하기 위함이었다. 치아결손증의 유병률은 남자(5.9%)가 여자(4.7%)보다 약간 높게 나왔으며, 남자에서 평균 선천적 결손치 수는 3.58개, 여자는 2.43개였다. 평균 선천적 결손치 수는 상악보다 하악에서 통계적으로 유의하게 높은 비율을 보였고(p < 0.05), 좌측과 우측치열간의 선천적 결손치 수의 차이는 통계적으로 유의하지 않았다(p > 0.05). 선천적 결손치가 가장 많이 분포하는 부위는 하악 제2소구치였으며 반대로 선천적 결손치가 가장 적게 분포하는 부위는 상 하악 제1대구치, 상악 중절치였다. 치아결손증 환자들에서 선천적 결손치의 악궁 내 대칭성 혹은 악궁 간 대칭성은 80.3%로 높게 나타났다. 이 연구의 결과는 임상의에게 선천적 결손치의 수와 위치에 대한 가치 있는 정보를 제공하여 정확한 진단을 내리고 바람직한 치료계획을 수립하는데 기여할 것이다.
