Abstract

Taurodontism is an anomaly characterized by a long and broad pulpal cavity and consumed apical location of the furcation area. This study aimed to determine the prevalence of taurodontism in deciduous molars based on digital panoramic radiographs of children. The study was performed on a sample of panoramic radiographs taken from 2,473 Korean children who visited the department of pediatric dentistry, Yonsei University Dental Hospital between Nov. 2005 and Mar. 2018. Taurodontism was mainly categorized by Daito's method. Using panoramic radiographs, taurodontism was also categorized into mesotaurodontism, hypotaurodontism, and hypertaurodontism. Mesotaurodontism was the most prevalent type. A total of 2,473 panoramic radiographs were evaluated. The prevalence of taurodontism was 5.7% in general, 51.5% in the left quadrant, 48.5% in the right quadrant, 6.3% in the maxilla, and 93.7% in the mandible. The distribution of taurodontism stratified by gender showed a higher prevalence in males. This is a comprehensive study on the prevalence of taurodontism in children using the largest sample size to date.

우상치는 수직적으로 긴 치수강과 근첨부에 위치하는 치수저를 특징으로 가지는 발육성 형태 이상이다. 이 연구의 목적은 어린이의 유구치에서 우상치의 유병률과 특징을 알아보기 위한 것이다. 이 연구는 2005년부터 2018년까지 연세대학교 치과대학병원 소아치과에 내원하여 파노라마 방사선 사진을 촬영한 만 5세에서 10세 사이의 환자 2,473명을 대상으로 시행되었으며 총 19,784개의 유구치가 평가되었다. 우상치의 유병률은 약 5.7%었고 남아에서 더 호발하였다. 또한 상악에서 6.3%, 하악에서 93.6%로 하악에서 현저히 높은 유병률을 보였다. 좌우에 따른 유병률의 차이는 나타나지 않았다. 우상치의 세부 유형으로 Daito의 방법을 적용하여 Hypertaurodontism, Mesotaurodontism, Hypotaurodontism으로 분류하였으며 각 유병률은 11.9%, 78.2%, 7.8%로 Mesotaurodontism이 가장 높은 유병률을 보였다.
