摘要

这项体外研究的目的是评估修复体周围的脱矿。在每颗牙齿的颊面和舌面进行V类预备。将TPH(1组)、Fuji II LC(2组)、Tetric(3组)、Dyract(4组)、GS 80(5组)和Chelon Fil(6组)随机放置在等量牙组中。牙齿被提交到与热循环模型相关的ph循环模型中。切片并在偏振光显微镜下检查标本是否存在脱矿。此外，在第2、4和5组中也观察到类似的抑制脱矿发展的作用。

In vitro-evaluation of secondary caries formation around restoration.

The objective of this in vitro study was to evaluate demineralization around restorations. Class V preparations were made on the buccal and lingual surfaces of each tooth. TPH (Group 1), Fuji II LC (Group 2), Tetric (Group 3), Dyract (Group 4), GS 80 (Group 5) and Chelon Fil (Group 6) were randomly placed in equal numbers of teeth. The teeth were submitted to a pH-cycling model associated with a thermocycling model. Sections were made and the specimens were examined for the presence of demineralization under polarized light microscopy. Demineralization was significantly reduced with Chelon Fil (Group 6). Furthermore, a similar inhibitory effect on the development of demineralization was observed in Groups 2, 4 and 5.
