Sažetak
The use of resin composite restorations might require repairs to prolong the service life of such restorations. The aim of this study was to evaluate the effect of 3 surface treatment methods on the shear bond strength (SBS) of a particulate filler resin composite (PFC) to 5 PFC substrates, namely Targis (Ivoclar), Sinfony (3M ESPE), Tetric (Vivadent), Gradia (GC), Sculpture (Jeneric Pentron)
in dry and thermocycled (TC) conditions. PFC substrates were fabricated according to each manufacturer’s recommendations and the oxygen inhibition layer was removed by grinding. The substrates in each group (n=6) were randomly assigned to each of the following 3 treatment conditions: (1) Etching for 90 sec with 9.5% HF (Ultradent® Porcelain Etch, USA) (2) Sandblasting (50μm Al2O3), (3) Tribochemical silicacoating (CoJet, 30μm SiOx, 3M ESPE). Each surface treatment was followed by silanization and bonding agent application. The repair resin (Sinfony, 3M ESPE) was bonded to the conditioned substrates using teflon tubes (3.6 x 5 mm). TC was
applied for 6000 cycles (5-55oC, 30 sec). The SBS were measured in a universal testing machine with a cross-head speed of 1mm/min. The ANOVA showed that SBS values before TC differed significantly (P<0.001) between the acid etched specimens (7.5-14.5 MPa) and those treated with either Al2O3 (15.9-20.8 MPa) or silicacoating
(25.8-42.2 MPa). After TC, the silicacoating process resulted in the highest values in all material groups (17.3- -30 MPa). The results indicate that composite resin repair strengths are dependent on the brand of the composite. This could be due to the differences in chemical composition of the polymer.
