Comparative Evaluation of Smart Dentin Replacement and its Combination with Fiber in Reinforcing Endodontically Treated Teeth: An In-vitro Study
Introduction: Root canal treatment is essential for addressing pulp damage caused by decay or trauma. However, it significantly weakens the tooth structure, especially in posterior teeth, which endure strong chewing forces. The resulting susceptibility to fracture necessitates careful selection of r...

| description | Introduction: Root canal treatment is essential for addressing pulp damage caused by decay or trauma. However, it significantly weakens the tooth structure, especially in posterior teeth, which endure strong chewing forces. The resulting susceptibility to fracture necessitates careful selection of restorative materials that can both protect and reinforce the remaining tooth structure. The present study explores novel restorative approaches using Smart Dentin Replacement (SDR) alone and in combination with Polyethylene Fiber (PEF) to potentially enhance the fracture resistance of endodontically treated mandibular molars, addressing the ongoing challenge of post-endodontic restoration.
Aim: To compare SDR and combination of SDR and fiber in reinforcing endodontically treated lower molars.
Materials and Methods: The present in-vitro study was conducted at the Department of Conservative Dentistry and Endodontics, Bharati Vidyapeeth (Deemed to be University) Dental College and Hospital, Pune, Maharashtra, India, from June 2023 to February 2024. It included a total of 27 extracted human mandibular posterior teeth, which were collected and embedded in acrylic blocks in groups of three, with nine teeth in each group (n=9). Teeth in the experimental groups (Groups 2 and 3) underwent access cavity preparation. Group 1 consisted of intact teeth. In Group 2, the access cavities were reinforced using SDR material. Group 3 involved reinforcing the inner circumference of the access cavities with a combination of PEF and SDR. The fracture resistance of all the teeth was then evaluated using a universal testing machine. One-way Analysis of Variance (ANOVA) and post-hoc Tukey’s test for intragroup comparison were used to calculate the statistical results of the present in-vitro study (p-value<0.05).
Results: The control group showed the highest fracture resistance (2178.20 N), followed by SDR+PEF (1872.57 N) and SDR (1740.40 N). The differences between all groups were statistically significant (p-value<0.001).
Conclusion: The combination of PEF and SDR material demonstrated superior fracture resistance in endodontically treated teeth compared to SDR alone. This reinforcement technique could potentially provide better clinical outcomes by enhancing the structural integrity of treated teeth, thereby reducing the risk of fracture and improving long-term success rates. |
