Background and objectives: Etching of a fiber post is necessary for enhancing its adhesion to both the core and the root canal dentin. Many surface treatments are recommended for this purpose. The purpose of the present study was to evaluate the efficacy of silanization on the push-out bond strength of H2O2-etched fiber posts to a root canal dentin using different luting agents.
Materials and methods: Sixty maxillary central incisors and fiber posts were taken and grouped, based on surface treatment posts received, as group I (control); group II and group III—etched with 24% H2O2, and sub-grouped (Ia Ib; IIa IIb; IIIa IIIb) based on the luting agent used. Group III received an additional treatment with silane before cementation and after etching. Each tooth was sectioned into three slices of 2 mm representing coronal, middle, and apical section of the tooth and subjected to a push-out test and the values obtained are statistically analyzed using two-way ANOVA and Tukey\'s post hoc tests.
Results: Among all the groups, group III irrespective of sub-groups showed the highest bond strength values followed by group II and then group I. Coronal region showed higher values than middle and apical.
Conclusion: Both the H2O2 etched groups (II and III) showed higher values than control group (group I). Silane treated groups (IIIa, IIIb) showed higher values than non-silanated group (IIa, IIb). There was no significant difference between the sub-groups (a, b) in all individual groups. In all groups, bond strengths were higher in coronal root region followed by middle and then apical.
