Abstract : [Introduction] Due to the rapidly increasing demand for aesthetic dentistry and progress in basic and clinical research in composite materials, resin composite has become a major aesthetic restorative material. One disadvantage of composite restoration, however, has been the tendency of the resin to stain with time. The cause of the staining is attributed to the adherence of micro particles to the solid surface brought about by a physicochemical interaction. In general, silane coupling agents to promote surface modification and/or adhesion are the most familiar example of the RnSiX4-n (n=1, 2 and 3) class of organosilane materials. These have two types of substituents where R is a nonhydrolyzable organic group that may be relatively inert in one case such as a hydrocarbon radical, or may be reactive to a particular organic system in another case. The X functionality is a hydrolyzable group, often an alkoxyl group. Silane coupling agents containing fluorocarbon chains exhibit the following properties : water and oil repellency, prevention of contamination, high lubricity, high abhesion, thermal and chemical stability, and less toxicity.
