摘要

The goal of this study was to evaluate the demineralization status at different acid-etch time based on fluorescence spectrum. Human molars in vitro of yellow race were cut into tooth sections and then they were immersed in 0.3% citric acid to simulate the oral natural demineralization. According to the acid-etch time, samples were randomly divided into three groups: Ⅰ:20 min, Ⅱ:40 min, and Ⅲ:60 min. The normal untreated specimen was set as control group. The fluorescence spectra before and after treatment were measured and analyzed. The result showed that fluorescence spectrum could be efficiently used to monitor the demineralization status of human dental tissue. The relative fluorescence intensities of dental tissue excited respectively with 260, 330 and 400 nm decreased with the increase of acid-etch time, though there was no new constituent formed after demineralization.
