عنوان انگلیسی Effects of 980 nm diode laser irradiation on bond strength of fiber posts to root canal dentin
چکیده انگلیسی مقاله Objective: The present in vitro study aimed to evaluate the effect of a 980 nm diode laser irradiation on the bond strength of fiber posts to intracanal dentine.Methods: Twenty-four extracted human maxillary central incisors were obtained. After root canal treatment, the samples were randomly divided into two groups (n=12): In group 1, root canal dentin was subjected to diode laser irradiation (980 nm, 1W, continuous wave) whereas group 2 was considered the control group and was not irradiated. Fiber posts were cemented using resin cement. The pull-out bond strength of the fiber posts was assessed with a universal testing machine. The data were analyzed by an independent samples t-test (α=0.05).Results: The average fracture strength of the laser-irradiated group (90.04 ± 30.45 MPa) was significantly higher than the control group (62.95 ± 22.09 MPa; P = 0.021).Conclusions: Diode laser irradiation to the root canal can increase the bond strength of fiber posts to intraradicular dentin.
