초록

최근 새로 개발된 DIFOTI(Digital Imaging Fiber-Optic Transillumination) 시스템의 초기 법랑질 우식증 진단 능력을 평가하고 임상 적용의 가능성을 타진해 보고자 본 연구를 시행하였다. 임상 연구는 유치 탈락 시기에 근접한 학령기 아동 23명을 대상으로 DIFOTI 이미지 촬영을 시행하고 자연 탈락된 유치 20개를 수거하여 CLSM 촬영 결과를 바탕으로 민감도(sensitivity)와 특이도(specificity)를 산출하였으며, 실험실 연구에서는 수거된 40개의 유치를 대상으로 Carbopol 인공 우식 용액으로 1, 2, 4 그리고 8일간 탈회시킨 후 각각 방사선 사진, DIFOTI 이미지 그리고 CLSM와 비교 분석하여 다음과 같은 결론을 얻었다. 1. 구내에서 촬영한 DIFOTI 이미지의 민감도는 0.61이었고, 특이도는 0.63이었다. 2. 실험실에서 인공 탈회시킨 유치의 협설면 초기 우식증에 대한 DIFOTI 이미지의 민감도는 0.71 였고, 특이도는 0.75 였다.

Abstract

The purpose of this study were to evaluate the efficacy of the newly developed Digital Imaging Fiber-Optic Trans-Illumination(DIFOTI) system in detecting carious lesions in in vivo as gold standard with confocal laser scanning microscopy and compared the efficacy of traditional radiography and DIFOTI system in in vitro as gold standard with confocal laser scanning microscopy, too. For the in vivo study, the subject pool consisted of 23 grammar school age patients just prior to entering the mixed dentition phase. Each patient was given a DIFOTI examination of the anterior and posterior teeth. During 6 ～ 8 months, the naturally expire primary teeth were collected and the efficacy of DIFOTI system was compared with confocal laser scanning microscopy. For in vitro study, 40 primary teeth were collected and decalcified by Carbopol decalcification solution for 1, 2, 4 and 8 days. Every experiment period, all teeth were DIFOTI examined and sectioned to take an image of confocal laser scanning microscopy. Sensitivity and specificity were calculated from the result of DIFOTI examine and confocal laser scanning microscopy analysis. The results are as follows: 1. From the in vivo study, the sensitivity of DIFOTI examine was 0. 61 and specificity was 0.63. 2. From the in vitro study, the sensitivity of DIFOTI examine was 0. 71 and specificity was 0.75.
