A digital imaging analysis (DIA) procedure for recording and assessing erosive changes on teeth was developed and evaluated against an older subjective method. Results after exposure of rats' teeth to various soft drinks showed that the DIA system was superior to the conventional method, with improved precision. The system provided a direct and highly sensitive means of quantifying the erosion of dental hard tissues by three different soft drinks, showing that it could be used to evaluate erosiveness and other dental damage. After 6 weeks' exposure to soft drinks in the diet, the area of intact enamel on the lingual surface of the first mandibular molar averaged 47% on apple juice, 27% on still orange and 6% on carbonated orange. The greatest exposure of dentine (36%) was on the still orange drink. Eroded enamel accounted for 72.5% of the tooth surface on the carbonated drink.
开发了一种用于记录和评估牙齿侵蚀性变化的数字成像分析（DIA）程序，并与一种较旧的主观方法进行了对比评估。将大鼠牙齿暴露于各种软饮料后，结果表明DIA系统优于传统方法，精度有所提高。该系统提供了一种直接且高度灵敏的手段，可量化三种不同软饮料对牙齿硬组织的侵蚀情况，表明它可用于评估侵蚀性和其他牙齿损伤。在饮食中接触软饮料6周后，第一下颌磨牙舌面完整牙釉质的面积在苹果汁组平均为47%，在无气橙汁组为27%，在碳酸橙汁组为6%。牙本质暴露最多（36%）的是无气橙汁饮料。碳酸饮料组牙釉质侵蚀占牙齿表面的72.5%。
