Abstract

Background: Following root canal treatment a tooth becomes brittle and weak, and most of the time is at a loss of significant tooth structure. Due to these factors, a post is indicated to aid in the retention of the core and overall final restoration. A post is a dental material placed in the root of a structurally compromised tooth. There are many types of posts available, also there are numerous factors to consider when choosing a post, based on what the clinician and the patient prefer.

Aims: The aim of our study was to compare the fracture resistance of endodontically treated teeth (ETT) restored with glass fiber posts, with those restored with composite posts, and using ETT with gutta-percha as the control group.

Materials and methods: A total of 15 extracted mandibular premolars were used in this study, divided into three equal groups (A, B, and C); five cases for each group. The teeth were sterilized, disinfected and root-treated. Their corresponding fracture resistance was then tested using the universal testing machine. The fracture load of each tooth was recorded and the data was preserved for analysis. Results: The findings of this study indicate that there was no statistically significant difference in fracture resistance values among the three study groups. The mean fracture resistance for group A was 388.25 kgf, group B 442.33 kgf and that of group C was 316 kgf. Conclusion: The placement of a fiber post system or a composite post does not strengthen a tooth structure or increase its fracture resistance.
