Abstract
The purpose of this study was to evaluate the surface free energy of composite resin with different surface
treatments. Six commercially available composite resin (Z250, P60, Metafil CX, Heliomolar, Grandio, and
Supreme XT) were tested. The surface free energy of composite resin after various surface treatments was
measured, and correlation between the types (microhybrid, microfilled, and nanohybrid) of composite resin and
the surface free energy was evaluated. The surface of specimen was polished with SiC paper in order of #2000,
#1000, and #600, respectively, and sandblasted with alumina (50 ㎛). Using 3 different liquids (deionized water,
formamide and 1-bormo-naphathlene), the contact angles of resin were measured with Image analyzer, including
the non-treated surface (control). The surface free energy of each specimen was calculated using
Li fshi tz-van der waals/aci d-base (LW/AB) method. Results were stati sti cally analyzed usi ng Turkey multi ple
comparison test (p=0.05). The surface free energy of composite resin was increased significantly compared to
the energy before the surface treatment (p<0.05). The surface free energy of nanofilled composite resin showed
significantly lower value compared to resin with other types of fillers, in non-treated surfaces. When the surface
was treated, the surface free energy of nanofilled composite resin showed higher tendency than other resins
with different types of fillers.
