Abstract:
OBJECTIVETo evaluate the effect of light irradiation intensity on bond durability of dual-cured resin luting agents to silanized ceramics.
METHODSLinkmax HV (LMHV), Nexus 2 (NX2), Variolink II HV (VL II HV) as dual-cured resin luting agents were bonded to silanized GN-I glass ceramics, and irradiated by 800, 310 and 80 mW x cm(-2) light intensity to form micro-shear test specimens. After 1, 90 d water storage, micro-shear bond strength of silanized resin/ceramic luting agent were measured. Data of each resin luting agent were analyzed by one-way ANOVA.
RESULTS90 d water storage decreased significantly the bond strength of all test groups, and the weak of irradiation intensity did not deteriorate this reduction of bond strength of luting resin/cermaic, oppositely in which LMHV irradiated by 310 mW x cm(-2) light intensity and NX2 irradiated by 80 mW x cm(-2) showed the higher bond strength than that irradiated by 800 mW x cm(-2).
CONCLUSIONThe weak of irradiation intensity does not affect the bond durability of dual-cured resin luting agents to silanized ceramics.
