Evaluation of Effect of 2% Chlorhexidine on Antibacterial Activity of Resin Cement

Aim: To evaluate the effect of 2% Chlorhexidine on antibacterial activity on Resin cement. Methods: A total of 100 patients of 29-56 years of age who required Fixed dental Prosthesis were selected for the study. 2 teeth were prepared in each patient for All Ceramic crowns. In every patient, the 2 teeth prepared were divided in to 2 groups: Control(no antimicrobial agent applied after etching of tooth) , Test (2% Chlorhexidine applied after etching of the tooth) , .Bacteriologic samples were collected at 5 different sample times: Baseline visit,at the time of cementation,1 ,3 and 6 month after cementation.Microbiogical processing of all samples were done and the results were statistically analysed. Result: There was significant shift in Control group towards Gram negative,anaerobic,rod atmosphere from Baseline till 6 month postcementaion. In Test group,atmosphere shifts towards Aerobic ,Gram positive ,cocci till 3 months post cementation but becomes Anaerobic ,Gram negative,cocci/rod in 6 month postcementation. Conclusion: This study shows that application of 2% Chlorhexidine on prepared tooth surface after etching definitely increases antibacterial activity of Resin cement.
