title: An in-vivo comparative evaluation of two herbal extracts Emblica officinalis and Terminalia Chebula with chlorhexidine as an anticaries agent: A preliminary study.
abstract: OBJECTIVE
  To compare the effect of 20% aqueous extract of Terminalia chebula and Emblica officinallis with chlorhexidine as an anticaries mouthwash - an in vivo study.
  
  
  METHODS
  20% aqueous extract of Terminalia chebula and Emblica officinalis were prepared. Forty five high caries risk patients were divided into group 1,2,3 [ n=15]and asked to rinse with 20% aqueous extract of Terminalia chebula and Emblica officinalis, 0.2% Chlorhexidine for 40 seconds respectively. Salivary samples were collected for pH, buffering capacity before and after rinsing at repeated intervals of 10, 30,60 and 90 minutes and except for microbial analysis for which it was collected before and 90 minutes after rinsing. The pH and the buffering capacity analysis was done using chairside kit and percentage of reduction of Streptococcus mutans and Lactobacillus were tabulated and statistically analyzed.
  
  
  RESULTS
  For salivary pH, Group 2 showed the highest peak value followed by group 1. For salivary buffering capacity, there was no significant difference between any of the groups. For microbial count, highest percentage of reduction was seen in group 2 followed by group 1 and 3. However group 3 was more efficient at 90 minutes followed by group 1 and group 2.
  
  
  CONCLUSIONS
  The aqueous extract of Embilica officinalis extract and Terminalia chebula was more effective anticaries mouthwash but with less time of action than chlorhexidine.
