Popis: Aim: The objective of the present study was to evaluate the microleakage of composite restorations alone orwith amalgam base in proximal box of class ? cavity preparation.Methode: Eighty proximal cavities (Mesio-occlusal and disto-occlusal) were prepared in 40 premolarswith carbide bur and randomly divided into four groups. Group A restored with composite resin; the otherthree groups restored with combined amalgam-composite restoration as follows. Group B the compositeinserted immediately after insertion of amalgam, group C the composite inserted after 5 minutes of amalgaminsertion while in group D the composite inserted after two days of amalgam insertion. Marginal adaptationwas evaluated at the following interfaces: tooth-amalgam(T-A), tooth-composite resin (T-C) and amalgamcomposite (A-C). Microleakage was evaluated by means of methylene blue infiltration after 21 days waterstorage and thermocycling aging. Microleakage was assessed by measuring the depth of horizontal dyepenetration. Image J analysis software was used to measure the penetration of dye in the tooth- fillinginterface and in the amalgam- composite interface. One-way ANOVA and post-hoc Tukey HSD tests (?=0.05) were used statistically for analyzing gather data.Results: There were a significant statically showed by ANOVA test between teeth -fillings interface,according to Tukey’s test there were a significant difference between teeth-composite interface and teethamalgam interface (p
