The aim of the study was to test the efficacy of 3% & 5% sodium Hypochlorite gel as compared to 3% and 5% sodium hypochlorite solution_ for deproteinization and also to assess the nanoleakage following deproteinization of dentin by an indigenous sodium hypochlorite gel, of varying concentrations with different tunings, using a conjocal laser scanning microscope. Seventy non-carious maxillary premolars were taken and Class V cavities were prepared on the cervical aspect with the cervical margin in dentin. The cavities were etched, rinsed with water and blot dried. Sodium hypochlorite was used at a concentration of 3 % and 5% both in the solution form and gel form for the study. Prime & bond NT was applied as per manufacturer's instructions and the cavities were restored with TPH spectrum composite resin. Teeth were immersed in 50% alcoholic solution of 1 % wt Rhodamine B fluorescent dye for 24hrs. After rinsing they were sectioned longitudinally and dentin / adhesive interface were examined under confocal laser scanning microscope. Dye leakage was measured in micrometers. Results suggest, Sodium hypochlorite gel is as effective as the solution form for deproteinization procedures and provides better handling and control. Efficacy of .sodium hypochlorite in reducing nanoleakage increases with increase in concentration and time. |
