Background: Different Ex vivo and in vivo studies show that mere mechanical preparation of the canals can leave the walls non instrumented. Chlorhexidine is a widely used irrigant solution that was developed in the year 1940s at United Kingdom. The present study was conducted to determine the effectiveness of 5% chlorhexidine solution. Materials and methods: The present prospective study was conducted in the department of endodontics for the period of 6 months. Sub culturing of all the micro organisms was done on apt culture media and under appropriate conditions. After the intubation period, growth inhibition zone was regarded as the shortest distance in mm from the outside margin of the stainless steel tube to the initial start of microbial growth. All the data thus obtained was arranged in a tabulated form and analysed statistically. Results: The areas of inhibition of S. Aureus for 1% chlorhexidine were 9.34 mm, for 2% chlorhexidine was 9.68 mm and for 5% chlorhexidine was 9.99mm. The areas of inhibition of S. sanguis for 1% chlorhexidine were 8.03 mm, for 2% chlorhexidine was 8.34 mm and for 5% chlorhexidine was 8.96 mm. Conclusion: From the above study it can be concluded that efficacy of 5% chlorhexidine as an irrigating solution is similar to 2% chlorhexidine solution.
Key words: Antimicrobial, chlorhexidine, irrigating.
