Abstract
[한글] 저자는 1965년부터 1983년까지 연세대학교 치과대학 부속병원과 서울대학병원에서 치근단 낭종으로 진단된 6세에서 70세사이의 남자 167명과 여자 139명의 환자에 발생한 319예의 치근단 낭종을 임상 방사선학적으로 분석하였다. 본 연구는 이 319예의 치근단 낭종을 촬영한 여러 유형의 방사선사진과 총 306명의 환자중에서 임상 기록 검토가 가능하였던 60명의 환자의 60예의 임상 기록부가 사용되었으며, 또한 환자의 연령 및 성별, 환자의 주소, 부위, 방사선학적 양상, 치아 변화, 병소에 의해서 침범된 해부학적 구조등에 따르는 치근단 낭종의 빈도와 분포를 분석하여 다음과 같은 결론을 얻었다. 1. 치근단 낭종의 발생 연령은 환자의 20대에서 가장 호발하였으며, 69.9%가 11세에서 40세 사이에서 발생하였다. 통계학적 분석은 성별 분포에서 유의의 차이를 나타내지 않았다(P>0.05). 2. 치근단 낭종의 호발 부위는 상악 전치 부위(44.9%), 하악 전치 부위 (15.9%), 상악 소구치 부위(14.8%)및 하악 소구치 부위(11.0%) 순이었으며, 상악과 하악의 비는 약 7:3이었다. 통계학적 분석은 좌우측 부위별 분포에서 유의의 차이를 나타내지 않았다(P>0.05). 3. 치근단 낭종의 침범은 치근단 부위를 포함한 경우가 전체의 92.2%로 가장 많았으며, 난형 및 타원형인 원형의 치근단 낭종이 전체의 88.7%이었고, 치근단 낭종을 둘러싸고 있는 완전한 과골 변연이 있는 경우가 전체의 66.8%이었다. 4. 치근단 낭종에 의해서 침범된 하나 또는 그 이상의 치근 흡수가 있는 경우가 전체의 55.2%이었으며, 침범된 하나 또는 그 이상의 치아 이동이 있는 경우가 전체의 23.1%이었다. CLINICO-RADIOLOGICAL STUDY OF RADICULAR CYST OF THE JAW Sung Youn Choi, D.D.S. Department of dental science, Graduate School, Yonsei University (Directed by Associate Prof. Han Pyong Kim, D.D.S., M.S.D., Ph.D.) The author analysed clinically and radiologically 319 radicular cysts which were proven histologically in Infirmary College of Dentistry Yonsei University and Seoul National University Hospital from 1965 to 1983, and which occurred in 167 males and 139 females between the ages of 6 and 70. This analysis was undertaken to discover the frequency and distribution of the radicular cysts with regard to the age and sex, the chief complaints of the patients, the regions, the radiographical appearances, the tooth changes, and the anatomical structures involved by the lesions. The obtained results were as follows: 1. The most frequently involved age group for the radicular cysts was the third decade of the patients, and the greatest number 69.9 per cent occurred between the ages of 11 and 40 years. The statistical analysis did not show any significant difference between male and female(P>0.05). 2. The frequently involved region for the radicular cysts was orderly the maxillary anterior region(44.9 per cent), the mandibula. anterior region(15.9 per cent), the maxillary premolar region(14.8 per cent), and the mandibular premolar region(11.0 per cent). The maxillo-mandibular ratio of the radicular cysts was about 7:3. The statistical analysis did not show any significant difference between right and left sides(P>0.05). 3. The greatest number was 92.2 per cent, which were involved in apical portions of the radicular cysts, 88.7 per cent of the radicular cysts were found in the round shapes which were oval and elliptical, and 66.8 per cent of the radicular cysts were observed with the completely hyperostotic borders. 4. The radicular cysts caused the root resorption in 55.2 per cent and the migration of the involved tooth or teeth in 23.5 per cent respectively.
