Abstract

Background and aim: Inadequate bond strength of RESIN CEMENTs to dentin appears to be a typical cause of failure in retention of fiber posts. In restoring endodontically treated teeth with fiber posts the cement-dentin interface is the weakest link. This study aims to compare the effect of self-etch and self-adhesive RESIN CEMENTs on shear bond strength of fiber posts to dentin.Materials and methods: This in vitro experimental study included 40 mandibular premolars with a single canal. All samples received standardized endodontic treatment after meeting the inclusion criteria. They were randomly divided into four groups and a post space was prepared in each sample. A size two Match post RTD fiber post was cemented into each sample using CoreCem (RTD) in group A, Panavia F2 (Kuraray) in group B, Bis Cem (Bisco) in group C and Maxcem Elite (Kerr) in group D as cementing agents. All samples were then cut into two pieces. Each specimen was loaded with equal force using a Universal Testing Machine. The load was applied from the apical to the coronal portion of each sample until fracture occurred. The mean shear bond strength for two each group was recorded and statistically analyzed with ANOVA (one way) and Dunnett’s tests using SPSS.Results: The mean shear bond strength was found to be as follows: Group A: (12.66 ±3.77) MPa Group B: (14.61±4.18) MPa Group C: (7.26±2.49) MPa Group D: (6.68±3.17) Mpa, Significant difference was demonstrated between shear bond strength of four groups (P=0.001). Mean bond strengths of RESIN CEMENTs in group A and B were not statistically different. Same results were shown when comparing cements in group C and D. However, cements in group A and B (self-etch) provided stronger bonds to dentin compared to group C and D (self-adhesive), the difference being statistically significant (P<0.05).Conclusion: The use of self-etch RESIN CEMENTs results in higher shear bond strength to dentin compared to self-adhesive RESIN CEMENTs.
