Aim: comparing the fracture resistance of roots obturated with gutta-percha using two different sealers.
Materials and methods: Forty human single-rooted mandibular premolars teeth were decoronated and standardized to 16 mm length. Instrumentation was done using PLEX-V system rotary file system up to PLEX-V 40.04. Samples were randomly classified into two equal experimental groups according to the type of sealer used for obturation of root canals (Adseal and Ceraseal). The roots were aligned vertically along their long axis in self-curing acrylic blocks and mounted on the universal testing machine to measure the fracture resistance. Data was collected and statistically analyzed.
Results: The fracture resistance values of the Adseal group were higher than the Ceraseal group. A statistically significant difference was found between Adseal group (I) and Ceraseal group (II) where (p<0.001).
Conclusion: Within the limitation of this study, it can be concluded that the obturation using Adseal resin sealer combined with gutta-percha points significantly increases the fracture resistance of endodontically treated teeth compared to Ceraseal bioceramic sealer combined with gutta-percha points.
