초록
본 연구의 목적은 초기 우식 병소에서 광원에 따른 형광효과를 비교하는 것으로 정량 분석형 laser/light 형광법(Quantitative laser/light-induced fluorescence, QLF)을 이용하여 아르곤 레이저광, 할로겐광, 발광다이오드광(LED), 플라즈마광의 형광효과를 비교하였다. 발거된 60개의 치아를 선정한 후, 인공우식용액에 노출되지 않을 부분에 nail varnish를 도포하였고 치아는 24, 48, 72 시간 동안 인공우식용액에 보관되었다. 건조 후 QLF영상으로 초기 우식 부위의 광밀도 차이에 의한 탈회정도가 기록되었다. 또한 조영제를 이용하여 동일한 방법으로 실험하였고 다음과 같은 결과를 얻었다. 염료를 이용하여 같은 방법으로 실험하여 또 다른 결과를 얻었다.1. 각 군의 평균 광밀도를 볼 때, 플라즈마광이 세 군 모두에서 다른 광원들 보다 높았다 (p<0.05).2. 세 군 사이에서 평균 광밀도를 비교해 볼 때, 플라즈마광과 할로겐광이 차이를 보였다(p<0.05).3. 조영제를 사용하였을 경우 평균 광밀도를 비교해 볼 때, 플라즈마광이 세 군 모두에서 다른 광원들 보다 높았고(p<0.05), 발광다이오드광(LED)와 아르곤 레이저광을 제외한 모든 광원이 차이를 보였다(p<0.05).4. 조영제를 사용하지 않은 경우와 사용한 경우 평균 광밀도를 비교해 볼 때, 사용한 경우에 모든 광원의 평균 광밀도 차이가 컸다.
Abstract
The aim of this study was to apply the quantitative light-induced fluorescence(QLF) and use of fluorescein-enhanced QLF method for quantitative assessment of early enamel demineralization in vitro, comparing effectiveness of light sources : argon laser, halogen lamp, light emitting diode (LED) and plasma arc lamp. Sixty extracted teeth were used, prepared by gentle pumicing and coating in an acid-resistant nail-varnish, except for an exposure to a demineralizing solution. Teeth were removed at regular intervals(24, 48 and 72hrs), air-dried and QLF image were taken. Mineral loss, as measured by difference of optical density, was recorded. For dye-enhanced QLF a 0.075% sodium fluorescein dye was applied after QLF examination and mineral loss was recorded. The following result were obtained : 1. Comparing with mean difference of optical density, plasma arc lamp was higher than other light sources in all group(p<0.05). 2. Comparing each group with mean difference of optical density, there was significant different using plasma arc lamp and halogen lamp. 3. For use of dye-enhanced QLF, comparing with mean difference of optical density, plasma arc lamp were higher than other light sources in all group (p<0.05). 4. With this model dye-enhanced QLF compared with QLF in optical nsity, dye-enhanced QLF was higher than QLF in optical density. From the results presented in this paper, it was concluded that plasma light source was more effective compared with other light source for the detection and the quantification of early enamel caries.
