An In Vitro Evaluation of the Use of Resin Liners to Reduce Microleakage and Improve Bond Strength of Amalgam Restorations
Abstract
Dental amalgam serves as an effective restorative material. Although new restorative systems are continually being developed and employed for the purpose of rebuilding damaged and diseased teeth, amalgam has remained the most commonly used posterior restorative material. In large part, amalgam's constancy has been a result of its many advantages which include ease of manipulation, high strength, and low cost. Amalgam has certain disadvantages which prevent it from being considered the ideal restorative material. Amalgam allows leakage in the microgap that is always present between it and the cavity margin and is also incapable of forming an adhesive bond with tooth structure. Recently, adhesive resin systems have been used as cavity liners in an attempt to reduce microleakage between amalgam and tooth structure. The resins' ability to adhesively bond amalgam to cavity preparations has also been investigated.
