Effect of finishing and polishing direction on the marginal adaptation of resin-based composite restorations in vitro

Abstract

for believing in me and giving me the opportunity to fulfill my professional goal. Finally, I thank the faculty, the staff and my precious classmates in the Department of Operative Dentistry and the Department of Family Dentistry at the University of Iowa. You are all truly wonderful.

A comparison of gingival marginal adaptation and surface microhardness of class II resin based composites (conventional and bulk fill) placed in layering versus bulk fill techniques

“…Filler particles are coated with silane before mixing them to the unreacted organic matrix. The purpose of the coupling agent is to transfer stresses to the particles in order to improve strength and mechanical properties of RBC's (Pierre 2011). RBC's are supplied in many consistencies and viscosities.…”
