| 摘 要： | 目的:验证数码照相牙色度分析法进行体内乳牙脱矿与再矿化研究的可行性。方法:选取58例平均年龄为4岁的儿童,以左上中切牙为实验牙,先染色、数码拍照,然后对实验牙面进行酸蚀、染色、数码拍照,最后在口腔环境内自然再矿化24h和1周后再染色、拍照,运用图像分析软件进行牙色度R、G、B值分析,比较酸蚀脱矿及再矿化前后牙色度的变化。用SPSS 19.0软件包对数据进行方差分析。结果:酸蚀脱矿后及再矿化24h后的色值(R、G、B)与基值有显著差异(P<0.05);在1周时间点上,只有B值与基值有显著差异(P<0.05);再矿化24h及1周后,牙色度值与酸蚀后相比有显著差异。结论:数码牙色度分析法可识别乳牙脱矿及再矿化前后牙色度的变化,可用于原位乳牙脱矿与再矿化研究。

| Abstract: | PURPOSE:The aim of this in vivo study was to detect the different ability of deciduous teeth in absorbing stain after de-or re-mineralization by color value analysis of digital photographs.METHODS:Fifty-eight children aging from 3.5 to 4.5 years old were recruited in this study.After clinical examination,the labial surface of an incisor was stained with 2% aqueous methylene blue and digitally photographed.Then an area of the deciduous tooth was etched with 37% phosphoric acid gel for 1 min.Immediately after... |
