Objective: To evaluate the amount of Streptococcus mutans concentration on acrylic tooth surface without bracket bonded on to it’s surface and to evaluate the efficacy of Propolis mouthwash and compare it with two other mouthwashes.

Materials and Methods: A total of 50 acrylic teeth were used with 10 teeth in group A without bracket and 10 teeth with bracket in Group B,C,D and E respectively. The first part of the study compared the difference in accumulation of Streptococcus mutans between group A and B. The second part of the study compared the efficacy of Propolis mouthwash with two other mouthwashes. The samples were incubated in bottles with Brain Heart Infusion Agar inoculated with Streptococcus mutans. The samples were then treated with the respective mouthwash and the samples were estimated through Real Time PCR for the bacterial count.

Results: The mean ct values of A,B,C,D & E were 39.02,34.8,39.4,37.7 and 35.3 respectively.

Conclusion: Bonding a bracket on to the tooth surface significantly increased the concentration of Streptococcus mutans. Propolis mouthwash had statistically significant antibacterial properties against Streptococcus mutans.
