title: Investigation of antibacterial efficacy of Acacia nilotica against salivary mutans streptococci: a randomized control trial.
abstract: This double-blind, randomized control trial sought to evaluate the clinical effects of 3 mouthrinses against salivary mutans streptococci (MS). Ninety high-caries risk volunteers were randomly assigned to 3 groups, each group using a selected mouthrinse BID for 30 days. Subjects in Group 1 rinsed with 10 ml of 50% Acacia nilotica, Group 2 subjects rinsed with 10 ml of 0.2% chlorhexidine (active control), and subjects in Group 3 rinsed with saline water (passive control). Unstimulated saliva samples were collected at baseline, 30, and 60 days. MS were cultured on mitis salivarius bacitracin agar, and colony counts were obtained. The margin of error was fixed at 5%. ANOVA and post hoc least significant difference tests were performed. There were significant decreases in the MS colony count in the A. nilotica and chlorhexidine groups at 30 days (85% and 83%, respectively) and at 60 days (65% and 63%, respectively) (P < 0.0001). The antibacterial action of A. nilotica against MS was similar to that of chlorhexidine.
