Evaluation of Different Finishing/Polishing Systems of a NanoHybrid Resin Based Composite Restorations
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 5
Abstract
Objectives: This study was conducted to evaluate quantitavely and qualitatively the effect of different Finishing/Polishing systems of a nano-hybrid resin-based composite. Materials and Methods: Forty cylindrical split molds (10 mm diameter and 2 mm thick) were constructed from Teflon. Three groups of a nano-hybrid resin-based composite specimens were prepared; ten per each Finishing/Polishing systems (n=10) and ten unpolished as a control. The specimens were tested quantitatively by profilomerty and qualitatively by atomic force microscope. Results: a significant difference was observed among polishing procedures (P<.0001). The highest roughness values were recorded for all the restorative material polished with one step system. There was no any polishing system could produce smooth surface similar to Mylar strip. Conclusions: Liquid polisher exhibited the least surface roughness among the tested polishing systems but still worse than Mylar strip.
