ABSTRACT
Objective:
To evaluate the effect of different polishing instruments on the microstructure of composite resin.Methods:
Specimens of 5 kinds of resins were randomly divided into three groups and were polished with Astropol(group A),Sof-Lex(group B) and Super-snap(group C)respectively(n=3 for each resin).Specimens of natural enamel surface were used as the controls(group D).The surface roughness(Ra)and microstructure of the specimens were evaluated by an atomic force microscope(AFM).Results:
Ra value in group A was lower than that in group B(P=0.015);Z350 XT resin obtained the lowest Ra value among the 5 kinds of resin specimens(P0.05).Conclusion:
Astropol polishing instrument is better than Sof-Lex;Z350 XT has better polish performance.The three polishing instruments are ef-fective in polishing the 5 composite resins.
