초록

본 연구는 QLF-D를 이용하여 와동 내벽에 형성된 초기 이차우식증을 탐지가 가능한지 평가해보고, 표면에서 관찰한 우식병소와 실제 와동 내벽에 발생한 병소 간에 차이가 있는지 확인해보고자 시행하였으며, 다음과 같은 결과를 얻었다. 시간의 흐름에 따라 시편의 표면에서 관찰되는 이차우식병소가 점점 진행되었다. 수복물 변연의 우식병소 부분이 수복물에 가려지거나 형광에 의해 우식부분을 육안으로 판단하기에 어려운 부분들이 보였으며, 수복물이 있는 경우의 ${\Delta}F$값은 $-14.20{\pm}3.24$, 와동만 있는 경우의 ${\Delta}F$값은 $-11.56{\pm}3.94$ 로 수복물이 있는 경우의 ${\Delta}F$값이 유의하게 높게 나타났다(p<0.001). 또한 수복한 표면에서 측정한 병소의 ${\Delta}F$값은 $-14.20{\pm}3.24$, 횡단면에서 측정한 병소의 ${\Delta}F$값은 $-18.64{\pm}3.75$로 횡단면보다 표면에서 측정한 병소의 ${\Delta}F$값이 약 1.31배 가량 유의하게 크게 나타났으며, correlation은 0.026으로 낮게 나타났다(p<0.001). 하지만 수복하지 않은 표면과 횡단면의 ${\Delta}F$값 간의 correlation값은 0.613으로 높게 나타났다. 이를 통해 QLF-D를 이용하여 표면에서도 이차우식병소의 탐지가 가능하다는 것을 알 수 있었다. 다만, 수복물에 의한 간섭이 있을 수 있고, 병소의 특성상 실제 병소의 심도보다 적게 측정될 수 있으므로 이에 대한 고려를 통한 탐지가 이루어져야 할 것이다.

The purpose of this study was to evaluate the detection ability of secondary caries using qunatitative light-induce fluorescence-digital (QLF-D) device. Twenty bovine teeth with cavity on surface were demineralized during 21 days for secondary caries lesion of cavity wall. After 21 days, cavity was filled using composite resin and cut the specimen in half with disc. Fluorescence loss of lesion on surface by time flow, cross sectional lesion, and lesion of filled or unfilled surface were analyzed using analysis software. ${\Delta}F$ (value of fluorescence loss) of the lesion on surface assessed by the QLF-D increased significantly over time up to 21 days. And ${\Delta}F$ value of lesion of filled surface is significantly lower than that of unfilled surface (p<0.001). ${\Delta}F$ of filled surface is 1.31 times of cross section lesion. The correlation of between ${\Delta}F$ of filled surface lesion and ${\Delta}F$ of cross section lesion was showed low agreement (0.026) and correlation of between ${\Delta}F$ of unfilled surface lesion and ${\Delta}F$ of cross section lesion was showed high agreement (0.613). In conclusion, secondary caries can be detected on surface using QLF-D. However, interference of fluorescence of filling material is the points to be especially considered for exact analysis of secondary caries lesion.
