Introduction The purpose of this study was to assess the influence of a thin layer of amalgam placed on gingival floor of class II composite restorations in primary molars. The clinical and radiographic findings and esthetic appearance of these restorations were also studied. Materials & Methods In this study 30 class II cavities were prepared in primary molars of 18 patients aged 6 to 8 years old (14 restorations in control group and 16 restorations in case group). In control group all cavities were filled with posterior composite resin incrementally after total etching and using Scotchbond MP as dentin bonding. In the study group, a layer of 1 mm thick amalgam was condensed on the gingival floor of the proximal box and then composite material was inserted. The restorations were evaluated at the base line , one week, one month and six months later and also bitewing radiograms were taken at the base line and six month later . Results Success rate of restorations regarding anatomical form, marginal discoloration, and color match was 100 in both groups. With regard to marginal adaptation after six months the rate was 84/6 in control group and 86/6 in study group. None of the patients complained of any pain or discomfort. No secondary caries and no radiographic pathological evidence were observed. Conclusion It is concluded that long term in-vivo and in-vitro studies should be carried out in order to prove the success rate of the class II combined amalgam- composite restorations.
