초록
본 연구는 기존의 DIFOTITM 시스템의 문제점을 개선하고자 LED와 디지털 카메라를 결합한 발전된 형태의 prototype DIFOTI 시스템을 만들고, 이를 기존 시스템과 비교 평가하기 위하여 인공 우식 용액으로 탈회시킨 법랑질 시편에 대하여 1 일부터 7일까지 영상을 촬영하고 분석하여 다음과 같은 결과를 얻었다. 1. 실험 기간에 따라 두 시스템 모두 우식 법랑질의 광투과도(index of transillumination)가 감소하는 양상을 보여 주었다. 2. DIFOTITM 시스템에 비해 prototype DIFOTI 시스템에서 건전 법랑질과 탈회 법랑질 간의 발광도(intensity of luminance) 차이가 더 적게 나타나는 양상을 보였다. 이상의 결과를 종합해보면 prototype DIFOTI 시스템은 전류 소모량이 적은 LED를 사용하여 배터리를 사용한 무선 시스 템으로의 개발 가능성을 보여 주었고, 디지털 카메라는 디지털 영상 기술의 발달과 함께 무선 전송 시에도 매우 높은 화질을 기대할 수 있어 차후에 보다 작고 사용이 편리한 DIFOTI 시스템을 개발할 수 있는 가능성이 크다 할 수 있다.
Abstract
This study was performed to improve the conventional DIFOTITM system(EOS Inc., USA) by developing the prototype of DIFOTI system which consists of light emitting diode(LED) and digital camera. The images of enamel surfaces treated under Carbopol 907 de-mineralizing solution were taken daily during 7 days of experimental periods by both DIFOTI systems. The results of comparative analyses of obtained images can be summarized as follows: 1. Trans-illumination indices of images taken from sample enamel surfaces were decreased with time in both systems. 2. The difference of intensity of luminance between sound and de-mineralized enamel surface in prototype DIFOTI system was shown to be relatively smaller than conventional DIFOTITM system. The application of LED light source in prototype DIFOTI system could possibly reduce the amount of current consumption and that could ultimately lead us to the successful development of wireless model with battery. The innovative development of digital camera is undoubtedly expected to create much clearer image despite of wireless transfer. LED and digital camera can be combined into a smaller size but a very important task of improving image manager and analyzing program into a simpler and easier one to manipulate has to be solved.
