Aims and Objectives: To examine adaptation of lining materials to dentin and resin under scanning electron microscope in Class V restorations. Materials and Methods: Seventy-five caries-free extracted maxillary and mandibular molars were selected, and Class V restoration cavities prepared. The cavities were filled with Dycal as liner, resin-modified glass ionomer (Vitrebond [VT]) as base and restored with composite in different combinations. The statistical software SPSS version 11.0 and Systat 8.0 were used for the analysis of the data. Results: Microgaps were seen when Dycal and VT were used as liners and bases under composite resin restorations. Conclusion: Hybridization of dentin significantly reduced microgaps, especially after adhesive was applied. |
