Date not reportedComposite resins are presently among the most popular esthetic restorative materials in dentistry. These materials offer excellent esthetic appearance, allow for conservative cavity preparation and are now becoming widely accepted for clinical use in primary molars 1-23. Despite the improvement of their properties, achieved with better materials and incremental placing techniques, composite resin restorations appear to have still several drawbacks: although similar to amalgam in short terms studies, they have a high long term failure rate, mainly due to discoloration, loss of retention and secondary caries3,11,19, are time-consuming and technique sensitive, lack anti-cariogenic potential and can be amenable to secondary caries at the cervical dentin margins 1, 2. Continued interest in providing advance in restorative esthetic materials led to the development of new generations of composites. Among the newest material developed is the use of minute amount of nanoparticles which convert composites to possess permanent antibacterial properties. It is of great interest to observe the clinical behavior of this new material when utilized in clinical practice. Thus the aims of the present in-vivo study are:
