Fracture Resistance Behavior of Endodontically Treated Teeth Obturated with Bioceramic versus Gutta-Percha Systems

Abstract

This study investigates the fracture resistance behavior of endodontically treated teeth obturated with bioceramic and gutta-percha systems. The research aims to evaluate the mechanical performance and durability of these two obturation materials, which are critical to the long-term success of root canal therapy. Thirty extracted human teeth with standardized root canal preparation were divided into two groups: one obturated using a bioceramic sealer and the other with a conventional gutta-percha system. The specimens were subjected to compressive loading using a universal testing machine until fracture occurred. The results demonstrated that teeth filled with bioceramic-based materials exhibited higher mean fracture resistance compared to those treated with gutta-percha, suggesting superior bonding and reinforcement properties. These findings indicate that bioceramic obturation systems enhance the structural integrity of endodontically treated teeth, potentially improving their clinical performance and longevity.
