[Amalgam, composites and compomers: comparative histologic study of effects on the periodontal tissues].
Amalgam, composite resin and compomer are frequently used in operative dentistry today. Earlier studies have shown the periodontal consequences induced by these materials if they have intracrevicular restorative margins. This study was performed on dogs where Class V cavities with apical margin located at the alveolar bone crest were prepared and restored with these materials. Three months later, the experimental and control sites were prepared for histological analysis. Mean bone loss was significant only with compomer. The mean length of the supracrestal connective tissue was almost the same with the three fillings. The length of epithelial attachment was the highest with composites. There was a decrease in the length of the biologic width from Day 0 to Day 90.
