title: Sensitivity answers sought in amalgam alloy microleakage study.
abstract: Sensitivity often occurs shortly after an amalgam restoration is placed. This phenomenon has been related in part to microleakage at the amalgam/tooth interface. When microleakage characteristics of a large number of commercially available dental amalgams were examined, results showed wide variation in the amount of microleakage.
