To assess the effectiveness of the REFIX technology in the remineralization process of initial caries simulated on bovine enamel. The assessment involved the analysis of backscatter intensity, which was determined from laser speckle images.
Twenty-one bovine teeth were divided into three groups: G1 and G7 were submitted to treatment with the REFIX technology for 1 and 7 days, respectively. The control group was treated with deionized water.
A significant difference in backscatter was found between the carious and sound areas in all groups (p = 0.0038, p < 0.0001, and p = 0.0002 for the control group, G1, and G7, respectively). The intergroup comparison revealed no significant difference among the groups studied.
REFIX technology did not alter the optical properties of the samples of bovine teeth with simulated initial caries lesions after 1 and 7 days of treatment.
评估 REFIX 技术在模拟牛牙釉质早期龋再矿化过程中的效果。该评估涉及激光散斑图像确定的背散射强度分析。
将 21 颗牛牙分为三组：G1 和 G7 分别接受 REFIX 技术处理 1 天和 7 天。对照组用去离子水治疗。
所有组的龋损区和正常区之间的背散射差异均有统计学意义（对照组、G1 组和 G7 组分别为 p=0.0038、p<0.0001 和 p=0.0002）。组间比较显示，各组之间无显著差异。
在治疗 1 天和 7 天后，REFIX 技术未改变模拟有早期龋损牛牙样本的光学性质。
