ABSTRACT

Aim: To assess the tensile strength of non-precious gold, cobalt-chromium (Co-Cr), and fiber posts cemented with Panavia F2 resin cement in root canals of endodontically-treated teeth.

Methods: This in vitro, experimental study evaluated 30 extracted single-rooted, single-canal maxillary central incisors. The post space was prepared and the teeth were randomly divided into 3 groups (n=10) of fiber post, non-precious gold, and Co-Cr post. All posts were cemented using Panavia F2 resin cement. The tensile bond strength was measured using a universal testing machine. Data were analyzed using SPSS version 18 via ANOVA.

Results:The mean tensile bond strength was 127.05±28.96 N in fiber post, 122.62±52.80 N in Co-Cr post, and 127.48±42.62 N in non-precious gold post group. The three groups had no significant difference regarding the mean tensile bond strength (P=0.996).

Conclusion: Considering the lack of a significant difference in tensile bond strength of the three types of posts as well as the optimal esthetics, easy application, and similar modulus of elasticity of fiber posts to dentin, fiber posts cemented with Panavia F2 resin cement would be ideal for use in endodontically-treated teeth.
