Abstract
Background. The aim of this study was to analyze the effect of G-Bond and Z-PRIME Plus on the bond strength between prefabricated zirconia posts and the root canal wall. Methods. The study was carried out on 21 premolar teeth with similar conditions. The samples were cut at the CEJ. After root canal treatment of the roots, the post space was prepared up to a length of 10mm. The samples were randomly assigned to two groups of 10. G-Bond was used in one group and Z-PRIME Plus in the other to prepare the posts’ surfaces. After cementation and mounting the samples in polyester, the post was cut from the apical area into three equal sections. The bond strength of the samples was tested using the push-out test on a universal testing machine. Data wereanalyzed using t-test. Results. The meanpush-out bond strengths in the control,G-Bond and Z-PRIME Plus groups were 14.3, 27.6±11.8 and 27.4±13.4N, respectively. There was no statistically significant difference between the two groups (P<0.9). Both methods of surface treatment increased bond strength. The bond strengths were different in different sections such as coronal, middle and apical in each group. Conclusion. There was no significant differencebetween the G-Bond and Z-PRIME Plus groups and both products in-creased the bond strength of prefabricated zirconia posts.
Highlights
The bond strength of non-metallic posts to root walls is one of the most important factors in choosing the best technique for repairing endodonti-JODDD, Vol 12, No 2 Spring 2018 cally treated teeth that have lost most of their coronal structure
This study was carried out on 21 premolars, 10 prepared with G-Bond and 10 with Z-PRIME Plus and one control tooth with no surface treatment
The bond strengths in the G-bond and Z-PRIME Plus groups were almost twice that of the control sample
Summary
The bond strength of non-metallic posts to root walls is one of the most important factors in choosing the best technique for repairing endodonti-JODDD, Vol 12, No 2 Spring 2018 cally treated teeth that have lost most of their coronal structure. The bond strength of non-metallic posts to root walls is one of the most important factors in choosing the best technique for repairing endodonti-. Use of posts to distribute torqueforces along the long axis of the root andprotect against the forces within the oral cavity in restoring endodontically treated teeth has always been a prominent issue.[1]. Many advantages have been listed for these posts such as their tensile strength, elastic modulessimilar to that of dentin, conservative canal preparation due to chemical bond to the canal and easier removal process in case of treatment failure and need for retreatment.[3,4,5]. The aim of this study was to analyze the effect of G-Bond and Z-PRIME Plus on the bond strength between prefabricated zirconia posts and the root canal wall
