[Problems of overhanging approximate amalgam fillings].
The authors summarize findings pertaining to overhanging approximate amalgam fillings and associated problems. They describe the most frequent causes of incorrect preparation of amalgam fillings, Black's class II, and their incidence in common dental practice. From data in the literature ensues that overhanging fillings on molars and premolars are an important secondary factor in inflammation of the periodontium. Insertion of an adequate approximate amalgam filling and its finish after hardening is one of the basic preventive measures in marginal periodontopathies.
