Abstract


Background:  The purpose of this study is to evaluate and compare the efficacy of microbiostatic property of 2% Tea tree oil (TTO) with 1% sodium hypochlorite (NaOCl) on thermally activated polymethylmethacrylate acrylic resin plate exposed to Candida albicans, Staphylococcus aureus and Streptococcus mutans.  Materials and Methods: 60 of 30x10x2mm standardized acrylic resin plates of uniform surface were divided into 2 groups of 30 each for 2% TTO and 1% NaOCl. Ten from each group were colonised by 106 viable cells per millilitre of respective microorganisms and were disinfected for 10 minutes. The remnant adhered microorganisms were dispersed, diluted and plated onto culture media to determine the number of colonyforming units.  Result: 1% NaOCl showed complete retardation for all the organisms whereas 2% TTO was effective against streptococcus mutans. Isolated samples of Candida albicans, Staphylococcus aureus showed no retardation with 2% TTO.  Conclusion: The results suggest that 2% TTO is effective against all tested microorganisms.
