COMPARATIVE EVALUATION OF SIX DIFFERENT BRANDS OF 3% SODIUM HYPOCHLORITE USED IN DENTISTRY TO ASSESS THE AMOUNT OF CHLORINE RELEASE AT DIFFERENT TEMPERATURES

Abstract

Sodium hypochlorite is widely used in dentistry as an irrigant at a concentration of 0.5-6%. In this study we have compared six different brands of 3% sodium hypochlorite at different temperatures to assess the amount of chlorine level. Six different brands of 3%sodium hypochlorite were subjected to physiochemical test to assess the free chlorine at different temperatures i.e. 27, 32, 37, 42,47,52,60 and 70 degrees. Comparisons of 6 brands of sodium hypochlorite were done at different temperatures by using one way anova. Multiple comparisons were made using Posthoc Tukeys test. Repeated measures anova was done to see if the release is different according to the temperature. None of the brands of sodium hypochlorite show any increase in chlorine content at different temperatures. Out of six brands used, the chlorine present in brands, i.e. Vishal, VIP, Novo and Deor was in accordance with the prescribed amount. The other brands, i.e. Deor and Chemedent lacked the proper amount of chlorine required.
