目的
比较三种玻璃离子水门汀（高填充玻璃离子水门汀、复合体、树脂改性玻璃离子水门汀）和树脂复合物（对照）对早期人工邻间龋的矿化作用。
方法
通过将牙齿样本和各种玻璃离子粘固剂放置在含有人工唾液的密闭容器中，在37 ℃和pH 7.0下持续30天，并持续循环，来模拟近端牙列。在90、180和270天用微型CT扫描仪获得断层图像，并使用密度测量软件计算标本中人工龋病变的微密度。比较各组的平均密度变化，以评估再矿化的影响。使用单因素方差分析和事后Tukey多重比较检验在P < 0.05下分析所有数据。
结果
而人工龋病变的密度增加的所有治疗，增加的三个玻璃离子组显着高于树脂组在每个3个月的时间。随着时间的增加，玻璃离子组的密度也增加，玻璃离子组的再矿化效果之间存在显著差异。显微CT被证明是一种有效的评价方法。
PURPOSE
To compare the remineralization of incipient artificial interproximal caries in the presence of three glass-ionomer cements (highly-filled glass-ionomer cement, compomer, resin-modified glass-ionomer cement) and a resin composite (control).
METHODS
Proximal restorations were simulated by placing tooth specimens and the various glass-ionomer cements in closed containers with artificial saliva at 37 degrees C and pH 7.0 for 30 days with constant circulation. Tomographic images were obtained with a micro CT scanner at 90, 180, and 270 days, and density-measuring software was used to calculate the micro-density of artificial caries lesions in the specimens. The mean density changes were compared between groups in order to evaluate the effects of remineralization. All data were analyzed using one-way ANOVA and the post-hoc Tukey multiple comparison test at P < 0.05.
RESULTS
While the density of artificial caries lesions increased for all treatments, the increases for the three glass-ionomer groups were significantly higher than that for the resin group in each 3-month period. As time increased, the amount of density also increased for the glass-ionomer groups, and significant differences were found between the remineralization effects of the glass-ionomer groups. The micro CT proved to be an effective evaluation method.
