Abstract
[한글] 교정진단분석의 목적으로 개발된 돌핀영상장치(Dolphin Imaging System)를 기존에 사용하고 있는 방사선계측법과 비교하기 위하여 정상교합을 가진 한국인 성인남자 26명, 성인여자 24명을 선별하여 측모두부 방사선사진을 촬영하고, 돌핀영상장치의 Digigraph Work Station을 이용하여 digitizing 하였다. 연세분석법과 Ricketts 분석법, Burstone 분석법으로 분석하고 비교가 가능한 계측항목을 상호 비교하여 다음과 같은 결과를 얻었다. 1. 비교가 가능한 세 가지 분석법외 64개 계측항목 중 13개 계측항목에서 통계적 유의 차가 없었다(p>0.05). 2. FH Plane을 기준으로 한 계측치들 중 유의차를 보이지 않은 항목이 3개인데 비해 SN Plane을 기준으로 한 계측치들은 모두 통계적 유의 차를 보였다(p<0.05). 3. 유의 차를 보이지 않은 항목은 대부분 비교적 짧은 거리의 거리계측항목이었고 각도계측항목은 대부분 통계적 유의 차를 보였다(p<0.05). COMPARISONS OF MEASUREMENTS OBTAINED FROM LATERAL CEPHALOMETRIC RADIOGRAPHS AND DIGIGRAPHS OF DOLPHIN IMAGING SYSTEM Hae Joon Park, D.D.S. Department of Dental Science, Graduate School, Yonsei University (Directed by Prof. Young Chel Park, D.D.S., M.S.D., Ph.D.) The purpose of this study was to compare the differences in measurements between cephalometric radiographs and digigraphs of Dolphin Imaging System. 26 Korean adult males and 24 adult females with normal occlusions were selected. For each subject lateral cephalogram was taken. Digitizing with Digigraph Work Station of Dolphin Imaging System was performed as well. 50 tracings and 50 digigraphs were analyzed with Yonsei, Ricketts, Burstone analyses. The Comparable measurements between tracing group and digigraph group were statistically analyzed. The results were as follows : 13 of 64 comparable measurements did not show any statistically significant difference(p>0.05) between tracing group and digigraph group. Three of the measurement with FH plane as a reference plane did net show any stastically significant difference. All measurement with SN plane as a reference plane lowed statistically significant difference(p<0.05). The measurement which showed no statistically significant difference were mostly short distance linear measurements while most of the angular measurements showed statistically significant difference(7< 0.05).
