Background and Objectives: Increased bacterial (streptococcal) biofilm aggregation on the surface of resin composite restorations in comparison with amalgam and glass ionomer restorations makes the composite restorations susceptible to secondary caries next to the restorations.  In this study, the anti-Streptococcus mutans properties of resin composites containing silver nanoparticles were inve...

Introduction: To date, surgery has been the treatment of choice for hydatid cyst, with regard to danger of leakage of hydatid cyst contents into viscera and production of secondary cysts, after spread of protoscolices.
