Microleakage Comparison of Amalgam-Composite Interface and Dentin-Composite Interface, the Two Surfaces Formed During the Defective Amalgam Margin Repairs with Bulk-Fill Resin Composite
Abstract
Objective: To compare micro leakage of amalgam-composite and tooth-composite interfaces, two surfaces formed and bonded during defective amalgam repair using Bulk-fill composite. Materials and methods: 25 extracted human molars were used for this research project: Prepared for two occlusal(O) cavities each has approximately2.7mm(W)X2.7mm(L)X2.7mm(H) dimension ; first cavity was prepared and filled with amalgam initially; one day later, the second cavity was prepared and filled to simulate a clinical repair using two different resin composite materials: 13 Bulk-fill composite(SDR) restoration sample as test group vs. 12 packable resin composite(TPH) restoration sample as a control group. All samples were stored in the distilled water at 25 degree Celsius for 60 hours, then they were placed in methylene blue dye solution for one hour; the samples were sectioned with slow speed isomet saw, and dye penetrations were assessed and compared at amalgam-composite interface and tooth-composite interface for both test and control groups.
