Comparative Evaluation of 25% propolis extracts and 2% chlorhexidine in decreasing bacterial load after sonic activation : An in vivo study

The aim of this research was to compare and evaluate bacterial load after using two different irrigating solution with sonic activation. Method: 20 patients indicated for root canal treatment categorized into 2 Groups. Group A (irrigant 25 % Propolis) n=10 Group B (irrigant 2% Chlorhexidine ) n = 10 . Sample A1 and B1 were collected immediately after access opening with the help of paper point in both groups. After complete biomechanical preparation canals were irrigated with 3% sodium hypochlorite , saline followed by sonic activation of 25% Propolis extracts .Same procedure was carried out for sample B2 in which 2% chlorhexidine was sonic activated . The entire sample were placed in liquid agar and incubated at 37 degree Celsius for 24 hrs to determine microbial load by colony forming unit .Statistics were used to tabulate and analyse the result.
