Abstract

본 연구는 韓國人의 乳齒保有者 1895명과 永久齒保有者 2167명을 대상으로 한
Pantomogram 사진을 이용하여 taurodontism의 발생빈도 및 호발 부위, 이와 함께 발생한
崎形齒牙를 조사하여 다음과 같은 결론을 얻었다.
1. 乳齒와 永久齒에서의 taurodontism의 발생빈도는 각각 3.59%, 1.8%이었다.
2. 乳齒에서는 中等度의 형태가 가장 많았으며,永久齒에서는 輕度의 형태가 가장 많았다.
3. 齒牙別 발생빈도는 乳齒에서는 下顎第一乳臼齒永久齒에서는 下顎第二大臼齒가 가장
높았다.
4. 複數齒에서 발생한 경우가 乳齒에서는 98.5%, 永久齒에서는 82%이었으며, 乳齒에서는
95.6%, 永久齒에서는 82%에서 양측성으로 발생되었다.
5. 乳齒와 永久齒에서 공히 남녀간 성차는 없었다.
#초록#
The incidence and associated dental abnormalities of taurodontism were studied
radiographically (panoramic view) in 1895 patients of deciduous dentition and 2167
patients of permanent dentition who had visited to the Department of Oral Radiology,
Kyung Hee University in Korea. The obtained results were as follows :
1. The prevalence of taurodontism was 3.59% in the deciduous dentition group, and
1.8% in the permanent dentition group.
2. There was no definite sex difference in the deciduous dentition, and the permanent
dentition group.
3. The type of mesotaurodontism was predominent in the deciduous dentition group,
and hypotaurodontism in the permanent dentition group.
4. The vast majority of this abnormalities had occurred in the mandibular 1st
deciduous molar in the deciduous dentition group, and mandibular 2nd permanent molar
in the permanent dentition group.
5. Of the cases with taurodontism, the deciduous dentition group revealed 95.6%
bilaterally, and 82% bilaterally in the permanent dentition group.
6. multiple teeth occurance, not single tooth only, were involved in 98.5% of the cases
in the deciduous dentition group, and 82% in the permanent dentition group.
