Introduction: Disinfection of the cavity preparation after caries excavation can lead to the elimination of bacterial remnants that can be responsible for recurrent caries, postoperative sensitivity, and failure of the restoration. The purpose of this study was to evaluate the effects of two disinfectants on microleakage of composite restorations in primary teeth. Metho...

background and aims. increasing the temperature of sodium hypochlorite (naocl) enhances its dissolution and antibacterial properties. however, the high resistance of multi-species biofilms could restrict the effect of the solution regardless of its temperature, enabling the long-term recovery of the surviving bacteria. the aim of this study was to investigate if the increase of temperature of n...

introduction: this in vitro study compared the antibacterial efficacy of 2.5% sodium hypochlorite gel and 2.5% and 5.25% sodium hypochlorite solutions on enterococcus faecalis ( e. faecalis ) biofilm. methods and materials: the root canals of 60 extracted human single-rooted teeth were contaminated with e. faecalis and incubated for 6 weeks. the samples were randomly assigned to three experimen...

introduction: sodium hypochlorite (naocl) is an effective antimicrobial irrigant, however its toxic effects and deterrent odor are not ideal. carvacrol is an edible plant extract with anti-inflammatory and anti-bacterial properties that is effective against enterococcus ( e ) faecalis . the aim of this study was to evaluate carvacrol's antibacterial efficacy against e. faecalis bacteria as a fi...

INTRODUCTION One of the uses of white mineral trioxide aggregate (MTA) is as an apical barrier in immature teeth. Although this treatment has been reported to have high success rates, a number of cases of discoloration have been noted. The aim of this research was to investigate the color stability of white MTA in contact with various solutions used in endodontics. METHODS The change in color...

A 12-year-old girl, with a previous history of bronchial reaction and contact dermatitis to sodium hypochlorite, was referred for root canal treatment. Complete immunologic evaluation revealed a mild hypersensitivity condition, as it was assessed by the RAST investigation to different allergens and the DTH reactivity expressed though migration inhibition test. The absence of a serious immunolog...
