PURPOSE The aim of this study was to answer the question: For patients requiring apicoectomy (apicectomy/root-end resection) and retrograde (root-end) obturation (filling), which retrograde obturation (root-end filling) material(s) is/are the most effective, as determined by reduction in periapical radiolucency and elimination of signs and symptoms? MATERIALS AND METHODS A MEDLINE and a Cochr...
The objective of the present study was to evaluate the efficiency of dental amalgam as retrograde filling material compared to gutta-percha. A prospective and comparative observational study was carried out on 30 patients at Khyber College of Dentistry, Peshawar from October 2004 to October 2009 with or without retrograde amalgam filling and the success was determined at the end of the year bot...

A dispersed amalgam showed significantly better resistance to two-body abrasion than the spherical amalgams tested. The wear amalgam was determined by resistance to penetration and by a ductile mode of surface failure over the load range studied. Differences in the wear of amalgam a...
