Abstrakt: The article presents a study that aims to clarify the impacts of thermo-cycle testing on prosthetic composite resin surface texture. Macroscopic observation showed a rough mat surface, and the pigment penetrations were raised on the thermo-cycled specimens. Furthermore, scanning electron microscopic (SEM) observation showed partial peeling and cracking of the thermo-cycled resin surface.
