Abstract

QLF-D system composed with DSLR(digital single-lens reflex) camera, and the images of natural enamel caries and artificial caries was developed from 2 days to 14 days captured by QLF-D system. The correlation between lesion depth of the polarized microscope and luminosity ratio of QLF-D image was analyzed and the results were summarized as follows: 1. The Pearson correlation value between the lesion depth of polarized microscope images and luminosity ratio of QLF-D images was 0.969(p<0.01). 2. From Regression analysis of lesion depth from polarized image by demineralized period, the equation was y = 8.67x - 1.16(p<0.05). 3. From Regression analysis of luminosity ratio from QLF-D image by demineralized period, the equation was y = 3.53x + 6.42(p<0.05). From the results, QLF-D system can detect the enamel caries at the very early stage and can monitor the progression of demineralization and remineralization. For the convenient use of QLF-D system in the laboratory, the image analysing software was needed to analyze of interest site of enamel caries lesion.

저자는 DSLR(digital single-lens reflex) 카메라를 이용한 QLF-D 시스템을 고안하여, 사람의 유구치에 자연 발생된 법랑질 초기 우식증을 관찰하고, 유구치 법랑질 시편을 대상으로 2일부터 14일까지 인공 탈회시킨 후 탈회 기간에 따른 상관관계를 편광 현미경 소견과 비교 분석한 결과 다음과 같은 결과를 얻었다. 1. 탈회 기간에 따른 편광 현미경 상의 병소 깊이와 QLF-D 영상의 광밀도 값 비율 간의 피어슨 상관 계수는 0.969였다(p<0.01). 2. 편광현미경에서 측정된 병소 깊이의 탈회 기간에 대한 회귀분석 결과 y=8.67x-1.16의 회귀 방정식이 산출되었다(p<0.05). 3. QLF-D 영상에서 측정된 광도값 비율의 탈회 기간에 대한 회귀분석 결과 y=3.53x+6.42의 회귀 방정식이 산출되었다(p<0.05).
