| Abstract | ||
| Background: Bioactive resin composites are aimed to discharge remineralizing ions, raise pH levels, and precipitate hydroxyapatite, thereby enhancing effectiveness of restorations. Aims: this study focused on evaluate and compare element analysis of restoration /dentin interface by SEM/EDX of conventional and bioactive bulk fill composite. Materials and Methods: A total of sixty extracted maxillary premolars was used. Teeth were divided into three groups based on the composite type: Group A (Tetric Power Fill), Group B (Predicta Bioactive), and Group C (Cention Forte). Each group was further subdivided into two subgroups: one without storage and one stored in artificial saliva for 30 days. The occlusal dentin exposed by sectioning 2 mm below the deepest occlusal point, and restorations was placed using the bulk-fill technique. Then the samples sectioned vertically in a mesiodistal way, and restoration–dentin interface was analyzed by SEM/EDX for elemental composition. Results: Cention Forte (storge group) exhibited highest Ca/P ratio (4.01±1.98), followed by its (non-storge) (1.97±0.38) while Predicta Bioactive showed high value in (storge group) (2.71±0.34). There was significant difference of Tetric power fill with both Cention Forte and predicta bioactive between nonstorage and storage groups at (p≤0.05). Conclusion: The SEM /EDX analysis exhibited an increase the Ca/P ratio in dentin area corresponding to both Cention Forte and Predicta Bioactive. Consequently, based on current study outcomes, these materials may be designated as bioactive bulk fill resin restorative materials. | ||
