WebJun 1, 2015 · Substantial surface microhardness of the restoration is one of the main requirements especially in posterior stress-bearing areas [23]. One of the most important factors that affect dental restoration is that it undergoes wear during function or whereas being cleaned [30]. As wear is due to abrasion, surface hardness is an essential property.
