چکیده
Objective: The present in vitro study aimed to evaluate the effect of a ۹۸۰ 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=۱۲): In group ۱, root canal dentin was subjected to diode laser irradiation (۹۸۰ nm, ۱W, continuous wave) whereas group ۲ 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=۰.۰۵).Results: The average fracture strength of the laser-irradiated group (۹۰.۰۴ ± ۳۰.۴۵ MPa) was significantly higher than the control group (۶۲.۹۵ ± ۲۲.۰۹ MPa; P = ۰.۰۲۱).Conclusions: Diode laser irradiation to the root canal can increase the bond strength of fiber posts to intraradicular dentin.کلیدواژه ها
