The effects of acid-etching duration on the surface of a glass ionomer cement designed for use as an intermediary layer between composite resin and dentine were investigated. Cement topography changes occurred which could be related to etch duration. When compared with enamel etched for a similar period, undue loss of cement substance was not observed for any of the etch times used.
研究了酸蚀时间对一种用作复合树脂与牙本质中间层的玻璃离子水门汀表面的影响。水门汀的形貌发生了变化,这可能与蚀刻时间有关。与蚀刻相似时间的牙釉质相比,在所使用的任何蚀刻时间下,均未观察到水门汀物质过度流失。
