Evaluation of Fracture Resistance of Endodontically Treated Maxillary Premolars Restored with Different Restorative Materials - An In Vitro Study

Objectives The aim of this study was evaluated longitudinally evaluate, after a 6-months period, the clinical performance of an alkasit- based material (Cention N, Ivoclar) in molars with root canal treatment. Methods The project was registered in the Brazilian Registry of Clinical Trials – REBEC (RBR-97kx5jv) on 19/01/2023. This randomized clinical trial that included 33 patients with an endodontically treated mandibular molar requiring restoration. Patients were randomly assigned according to the restorative treatment: control: restoration with Bulk-fill resin (Ivoclar - n = 17) and restoration with alkasite-based material (Ivoclar - n = 16). A self-etching adhesive was applied. Three calibrated professionals used the United States Public Health Service (USPHS) criteria to evaluate retention, secondary caries, marginal adaptation, restoration color, marginal pigmentation, and anatomical shape at seven days (baseline) and six months. The radiographic analysis assessed the presence of a radiolucent line adjacent to the restoration, the lack or excess of the material, contact point, and caries recurrence in both periods. Data were analyzed by Friedman, Kruskall-Walis, and Wilcoxon tests (α = 0.05). Results After 6 months of follow up, the Alksite-based demonstrated greater wear of the anatomical shape (p = 0.022), and a greater color difference compared to natural tooth (p = 0.0332), both with a statistically significant difference. All other criteria did not show significant differences between the materials or the analysis periods. Conclusion The use of Alkasite-based material on endodontically treated teeth influenced the color and anatomical shape performance, however did not influence the longevity and success of the composite restorations after six months. Clinical Relevance Alkasite Based material may be an alternative for the restoration of endodontically treated teeth
