Nanotechnology in Dentin Disinfection: Can We Preserve the Bond?

AIMS

The aim of this study is to evaluate the effect of cavity disinfection with 2% chlorhexidine (CHX) and Ag-Au nanoparticles on microleakage and resin tag penetrability of composite restoration under conditions.

MATERIALS AND METHODS

Twenty-five human permanent molars extracted for therapeutic reasons were used in the study. Class V cavity of standard dimension was prepared on the buccal and lingual surfaces of the teeth. The teeth were randomly allocated into two groups based on the cavity disinfectant used: group I being 2% CHX gluconate (chlorhexidina Friedrich and Bianca Mittelstadt (FGM)) and group II being cavity disinfectant containing Ag-Au nanoparticles (nanocare gold). In both the groups, the dentin was etched with 37% phosphoric acid and cavity disinfectants were applied following which dentine bonding agent and composite resin were applied and cured. The specimens were then viewed under a stereomicroscope and a scanning electron microscope for microleakage and resin tag formation, respectively.

RESULTS

The results were statistically analyzed using an independent "" test. No significant difference was seen between the two groups with respect to both microleakage and resin tag penetration values ( > 0.05).

CONCLUSION

The cavity disinfectant containing Ag-Au nanoparticles did not affect the sealing ability and resin tag penetrability of composite resin in permanent molars when compared with 2% CHX.
