Assessment of fracture resistance of stainless steel post, Carbon fiber post and ceramic post in endodontically treated teeth: A comparative study

AUTHOR(S): Sanjeev Chauhan and Tanuj Singh
ABSTRACT:Background: Endodontically treated teeth present a high-risk of biomechanical failure due to the loss of tooth substance resulting from pre-existing decay and endodontic therapy itself. Many non-metallic prefabricated posts have been introduced such as fiber based posts with excellent physical properties. Hence; the present study was undertaken for assessing and comparing the fracture resistance of stainless steel post, Carbon fiber post and ceramic post in endodontically treated teeth.
Materials & methods: A total of 45 freshly extracted maxillary canines were enrolled in the present study. Biomechanical preparation was done in all the specimens followed by obturation with lateral condensation technique. After preparation of post space, all the specimens were broadly divided into three study groups depending upon type of post used- Stainless steel post, Carbon fiber post and Ceramic post. By using adhesive resins, cementation of the posts was done using adhesive resins. After cementation, all the specimens were stored in normal saline for 24 hours followed by mechanical testing under universal force testing machine. All the results were recorded in Microsoft excel sheet and were analysed by SPSS software.
Results: Mean force required for fracturing specimens of stainless steel post group was 523.86 N. Mean force required for fracturing specimens of Carbon fiber post group and Ceramic post group was found to be 459.12 N and 376.67 N respectively. In the present study, while analysing statistically, it was seen that stainless steel posts had highest fracture resistant followed by Carbon fiber posts. Fracture resistance was found to be minimum for ceramic post.
Conclusion: Stainless steel posts exhibit maximum resistance to fracture in comparison to carbon fiber posts and ceramic posts.
