Abstract

Congenitally missing teeth are one of the most prevalent dental anomalies in the oral cavity. In this study, the prevalence, distribution, and symmetry of congenitally missing permanent teeth among 1,865 patients aged 7 to 15 years who visited the Pediatric Dentistry Department of Wonju Severance Christian Hospital from March 2011 to May 2021 and took panoramic radiographs were investigated and analyzed. Most of the patients had one or two congenitally missing teeth, mainly in the second premolars and lateral incisors. Congenitally missing teeth occurred more in the mandible than in the maxilla, and there was no significant difference in prevalence between the left and right sides. Congenitally missing teeth tend to occur symmetrically on the left and right sides and in the maxilla and mandible, depending on the tooth. Early oral examination and radiological examination are required to prevent complications due to congenitally missing teeth, and appropriate interdisciplinary treatment is required.

선천성 치아결손은 구강 내에서 가장 호발하는 치아 이상 중 하나이다. 이 연구에서는 2011년 3월 11일부터 2021년 5월 31일까지 연세대학교 원주세브란스기독병원 소아치과에 내원하여 파노라마 방사선 사진을 촬영한 7 - 15세 환자들 1865명에 대한 선천성 치아결손의 발생빈도, 분포 및 대칭성에 대해 조사 및 분석하였다. 대부분의 환자들은 1 - 2개의 선천성 치아결손을 가지고 있었으며, 주로 제2소구치와 측절치에서 발생하였다. 선천성 치아결손은 상악에 비해 하악에서 더 많이 발생하였고, 좌/우측 간에는 유의한 발생빈도의 차이를 보이지 않았다. 선천성 치아결손은 치아에 따라 좌/우측 및 상/하악 대칭적으로 발생하는 경향을 보였다. 선천성 치아결손으로 인한 합병증을 예방하기 위하여 조기 구강검진과 방사선 검사가 요구되며, 다학제 진료를 통한 적절한 치료가 제공되어야 한다.
