Comparative analysis of effect of fruit juices on surface roughness of bulk fill and flowable composite material

Abstract

Resin-based composites have been widely used to reconstruct anterior and posterior teeth, as dentistry has progressed and there has been an increasing interest in the creation of suitable materials to replace damaged tooth tissue. The aim of the study is to compare the effect of fruit juices on the surface roughness of bulk fill and flowable composite restorative material. A total of 8 bulk fill composite and flowable composite resin disc samples were made. These eight samples were tested for surface roughness following immersion in three juices which were pineapple juice, lime juice, orange juice, and distilled water as the control group. They were immersed at room temperature for 7 days. Surface roughness was evaluated by the Mitutoyo SJ-310 contact profilometer. It showed that there was a decrease in the Ra value of flowable composite when compared to bulk fill composite. Rq and Rz values were more for the flowable composite resin group. Flowable composite resin samples had more surface roughness than bulk fill dental composite restorative material after exposure to pineapple, lime, and orange juices.
