[Clinical problems of microleakage of restorative materials in primary teeth].

Abstract

The purpose of this research is to evaluate the clinical problems associated with microleakage of different restorative materials. We have compared the microleakage when we restore Class II cavities in primary molars with amalgams and with posterior composite resins. The results of this study suggest that posterior composite resins present more frequently pulp inflammation, necrosis, marginal discoloration and secondary marginal caries. This factors mus to be considered when we choose a material for temporary restoration.
