title: [The marginal leakage of amalgam and Vitrebond restorations after an occlusal load test].
abstract: The use of adhesive liners in amalgam fillings and restorations is a recent form of conservative dentistry. The aim of our study was to assess marginal microleakage in amalgam and Vitrebond restorations after occlusal load test. Using extracted teeth, we prepared 16 class II amalgam restorations, (Valiant ICQ, Caulk). Adhesive liner, (Vitrebond, 3M USA), was used in half of these. The samples then had first a cyclic load test, (27 kg per 7,000 cycles), followed by a microleakage test, (sample immersed in 2% erythrosin solution for 24 hours). The results showed that, in samples with adhesive liner, color penetrated to a statistically lesser extent than in the control group without Vitrebond.
