초록
이 연구는 2008년 1월부터 2013년 1월까지 전북대학교 치과병원 소아치과에 내원한 만 7~15세 사이 환자 중 파노라마방사선사진을 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.
Abstract
The purpose of this study was to find out prevalence of peg-laterals and to evaluate the frequency of dentalanomalies in Korean children with peg-laterals. For this study, panoramic radiographs of 3,278 patients (aged 7to 15 years) from the Department of Pediatric Dentistry admitted from January, 2008 to January, 2013 wereselected for an investigation on peg-laterals distribution. The prevalence of peg-laterals was 2.62% (86 subjects). Among the peg-laterals children, the distribution ofassociated 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 isto consider such relationships before deciding on a diagnosis and treatment plan.
