PURPOSE
To evaluate the effect of Carisolv solution on the topography and surface hardness of dentin.
METHODS
Two separate studies were carried out. Atomic force microscopy (AFM) was employed to visualize dentin surface topography on slices of previously extracted non-carious and carious teeth following the passive application of Carisolv gel for 30- and 60-second periods. A Wallace hardness instrument was used to measure the dentin surface hardness following active caries removal with Carisolv gel and the specially designed instruments. Conventional caries removal with dental burs and non-carious dentin acted as controls for the latter study.
RESULTS
AFM revealed that the passive application of Carisolv gel resulted in smoother surfaces than observed on carious and non-carious dentin. There was a statistically significant difference between the mean hardness values for non-carious and Carisolv-treated dentin (P< 0.05). There was no statistically significant difference between the non-carious and bur-treated dentin nor the Carisolv and bur-treated dentin.
目的
评估伢典溶液对牙本质表面形态及硬度的影响。
方法
进行了两项独立研究。在先前拔除的非龋和龋坏牙齿切片上被动涂抹伢典凝胶30秒和60秒后，采用原子力显微镜（AFM）观察牙本质表面形态。使用华莱士硬度仪测量用伢典凝胶及专门设计的器械主动去除龋坏后牙本质表面的硬度。用牙科车针常规去除龋坏及非龋牙本质作为后一项研究的对照。
结果
AFM显示，被动涂抹伢典凝胶后的表面比龋坏及非龋牙本质表面更光滑。非龋牙本质与经伢典处理的牙本质的平均硬度值之间存在统计学显著差异（P<0.05）。非龋牙本质与经车针处理的牙本质之间以及伢典处理的牙本质与经车针处理的牙本质之间均无统计学显著差异。
