ABSTRACT

Background:

Teeth that have undergone endodontic treatment are more likely to fracture because of the remarkable loss of tooth structure. Various post systems, like prefabricated carbon fiber posts, customized glass fiber posts, have been used to restore endodontically treated teeth (ETT). However, the effectiveness of these in enhancing fracture resistance remains a subject of debate.

Objective:

To evaluate and compare the fracture resistance of endodontically treated teeth restored using 3 different post types: prefabricated carbon fiber post, custom-made glass fiber post, and SFRC-relined fiber post.

Methods:

A total 30 extracted human teeth would undergo endodontic treatment and will be segregated into 3 groups based on the post type 1: Pre-fabricated carbon fiber posts 2: Customized glass fiber posts 3: SFRC-relined fiber posts The samples would be subjected to a universal testing machine to assess their fracture resistance. Data will undergo statistical analysis using ANOVA and post-hoc test.

Results:

Mean fracture resistance is expected to be highest in the SFRC-relined fiber post group, followed by customized glass fiber post group, and lowest of prefabricated carbon fiber post group. Statistically significant differences are anticipated among groups (p < 0.05). The SFRC-relined fiber posts are also expected to demonstrate more favorable failure modes compared to the other groups.

Conclusions:

The study suggests that SFRC-relined fiber posts provide superior fracture resistance and more favorable failure modes in comparison with prefabricated carbon fiber and custom-made glass fiber post. This finding highlights potential clinical benefits of using SFRC-relined fiber post. Clinical Trial: Since this investigation will be conducted entirely as an in vitro study, registration with the Clinical Trials Registry - India (CTRI) will not be applicable and therefore not required.
