| Abstract | ||||
| Objective: This study was conducted to analyze the interfacial micromorphology of three commercially available bioactive restorative materials to dentin. Materials and methods: Three different bioactive restorative materials were utilized: Surefill One (self-adhesive hybrid composite), Cention Forte (Alkasite-based restorative material), and Fuji II LC (resin-modified glass ionomer). A total of fifteen sound permanent molars were collected and randomly divided into three groups (n=5) according to the restorative material used. Following exposure of mid-coronal dentin of teeth through occlusal grinding, the restorative materials were applied according to manufacturer instructions. Specimens were prepared for SEM analysis through vertical sectioning with a diamond saw, polishing, acid-base challenge exposure, and final cleaning and drying. Scanning electron microscopy examination was conducted at 2000x magnification in secondary electron mode. Results: Regarding the interfacial micromorphological analysis of the three tested materials using SEM, there was a significant difference between the tested groups; The hybrid layer and acid resistance layer were observed in alkasite-based restorative material and resin-modified glass ionomer groups but the interfacial gaps were observed in self-adhesive hybrid composite group. Conclusion: Alkasite-based restorative material bonded most effectively and demonstrably to dentin compared to the other materials. | ||||
