Metallic dental restorations. A performance survey

A radiographic survey was conducted to assess professional performance in restorative dentistry. Analysis of 629 proximal metallic margins of restorations revealed a significant level of imperfection. The discrepancies at the gingival margins were measured on a tracing of the restoration using a grid and a Boley gauge. The results were consistent with other data. Contributing factors which explain this phenomenon are offered as well as considerations for the profession regarding the review of care quality.
