Abstract
This research aimed to study the effect of organic fillers on the surface microhardness of restorative resin composites. Forty resin composite specimens in the dimension of 4x4x2 mm3 were divided into four groups (n=10) according to the filler type: Fantasista V, Clearfil AP-X ES2, Clearfil AP-X, and Filtek Z350XT. Vicker hardness test (VHN) was carried out in all specimens with eight indentations, each with 100 g of loading for 15 s. The data were analyzed with one-way ANOVA and the Games Howell test. There were statistical differences between the groups of specimens (p<0.05) except Fantasista V and Clearfil AP-X ES2 (p>0.05). The maximal surface microhardness value was found in Clearfil AP-X, comprising of glass-based inorganic fillers. While the organic-filler based composites (i.e. Fantasista V and Clearfil AP-X ES2), had the lowest surface microhardness. However, they showed the better filler retention compared to the inorganic filler groups. In conclusion, organic fillers lessen the microhardness value but minimize filler dislodgement compared with inorganic fillers.
