Abstract
The aim of this study was to compare the surface gloss and micro hardness of two types of tooth colored restorative materials (Ketac Universal Aplicap glass ionomer and Vertise Flow self adhesive resin composite), after the exposure to in-office bleaching agent.
Materials and methods: A total of twenty discs were divided into two equal groups of two tested restorative materials; Ketac Universal Aplicap Glass ionomer and Vertise flow self adhesive flowable resin composite. In-office teeth whitening gel was applied on each specimen surface. Measurement of the surface gloss and micro-hardness was done to all the specimens before and after the bleaching procedure.
Results: The surface gloss of both tested materials showed lower mean value after bleaching than before bleaching and was statistically significant. On the other hand, the micro-hardness of both tested materials showed lower mean value after bleaching than before bleaching and was statistically significant.
Conclusion: the surface configuration and micro-hardness of both tested materials were negatively influenced when subjected to in-office bleaching.
