title: Marginal fracture of amalgam: effect of type of tooth and restoration class and size.
abstract: In this study of the marginal fracture of clinical amalgam restorations, it was found that restoration class or size did not influence fracture behavior, and a contralateral pair design was not found to be necessary. However, a slight effect was found for tooth type.
