Effects of Immediate Coating on Unset Composite with Different Bonding Agents to Surface Hardness.

Objectives:  This study evaluated the surface microhardness of composite, affected by surface coating with different dental adhesive systems.

Materials And Methods:  A total of 100 composite discs were divided into five groups. Group 1 was uncoated (control group C), and groups 2 to 5 were coated with different adhesive systems (OptiBond FL: FL, OptiBond SOLO Plus: SOLO, OptiBond XTR: XTR, and OptiBond All in one: AIO, respectively).
