Dental caries and periodontal diseases are the two most common chronic diseases of the oral cavity. Bacterial accumulation on oral surfaces is amajor factor in the development of most of the common dental diseases such as dental caries and periodontal disease. In the present investigation, four chemical mouth rinses and one herbal mouth wash were employed to assess antibacterial activity in liquid media against pure cultures of bacteria and oral flora in saliva. Different mouthwashes were found to exhibit varying effects on bacteria tested. The efficacy of different mouthwashes was found to be little less on B.subtilis and E.aerogenes when compared to other test bacteria. Themouthwasheswere found to have appreciable activity against growth of oral flora. Among mouthwashes tested, Mougel was found to inhibit the growth of oral bacteria to more than 50% followed by Chlorhexidine and others. Among chemicals, Chlorhexidine was found to inhibit oral flora to large extent. The ayurvedic mouthwash Mougel which was found to affect oral flora to a greater extentwhen compared to some chemicals. The antibacterial activity of Mougel could be possibly due to the presence of phytochemicals. The study was done in vitro and similar results could be expected in vivo. The right use of mouthwashes at right time could be very effective in the prevention of dental caries and other periodontal diseases.
