shabeel pn

The document discusses common failures of dental amalgam restorations. It identifies several factors that can lead to restoration failure, including faulty case selection, cavity preparation, matrix adaptation, and amalgam manipulation. Specifically, it notes that inadequate cavity preparation is the greatest single factor for failure, accounting for 56% of cases. Failure can occur due to factors like insufficient extension, overextension, line angles not being rounded off, and contamination during the restoration process. The document provides details on proper cavity preparation and amalgam placement techniques to help minimize failures.
