Abstract

The purpose of this study was to find out prevalence of peg-laterals and to evaluate the frequency of dental anomalies in Korean children with peg-laterals. For this study, panoramic radiographs of 3,278 patients (aged 7 to 15 years) from the Department of Pediatric Dentistry admitted from January, 2008 to January, 2013 were selected for an investigation on peg-laterals distribution. The prevalence of peg-laterals was 2.62% (86 subjects). Among the peg-laterals children, the distribution of associated dental anomalies were as follows: congenitally missing teeth (29.1%), dens invaginatus (19.8%), impacted teeth (12.8%), supernumerary teeth (9.3%), and transposition (4.7%). Due to this study showing frequent occurrences of peg-laterals with other dental anomalies, one suggestion is to consider such relationships before deciding on a diagnosis and treatment plan.

이 연구는 2008년 1월부터 2013년 1월까지 전북대학교 치과병원 소아치과에 내원한 만 7~15세 사이 환자 중 파노라마 방사선사진을 촬영한 3278명(남자 1814명, 여자 1464명)의 환자를 대상으로 상악 왜소측절치의 유병률 및 상악 왜소측절치와 연관된 치아발육장애의 발생빈도에 관하여 조사하였다. 상악 왜소측절치의 유병률은 2.62%(86명)로 나타났고 남자 47명, 여자 39명으로 남자에서 약간 높았다. 상악 왜소측절치를 가진 환자 중 발생빈도가 높게 나타난 치아발육장애는 선천성 치아결손 29.1%, 치내치 19.8%, 매복치 12.8%, 과잉치 9.3%, 전위 4.7% 순으로 나타났다. 이로서 상악 왜소측절치는 다른 치아발육장애와 동반되어 나타나는 경우가 많았으므로 진단 및 치료계획 수립 시 이를 고려해야 할 것으로 생각한다.
