Abstract

Aim: This study was aimed to compare the antibacterial effect of a commercially available OzOO with CHX 0.12% oral rinse solution against periodontal pathogens F. alocis, Aa, S. mitis, and S. mutans using a disk diffusion method.

Materials and Methods:

The antimicrobial agents OzOO and 0.12% CHX were impregnated onto sterile discs and placed onto bacterial cultures of F.alocis, Aa, S.mutans, and S.mitis to evaluate their antimicrobial activity by the disk diffusion susceptibility method. The bacterial growth inhibition zone surrounding each disc was measured in millimeters of diameter with calipers to assess the antimicrobial activity of each agent.

Results:

The mean ± SD diameter of the zone of inhibition for F. alocis was 24 ± 1.39mm for OzOO and 32 ± 2.64 mm for CHX. The mean ± SD diameter of the zone of inhibition for A.a was 0 ± 0mm for OzOO and 19 ± 1.5mm for CHX. The mean ± SD diameter of the zone of inhibition for S. mutans was 0 ± 0mm for OzOO and 19.4 ± 1.5 mm for CHX. The mean ± SD diameter of the zone of inhibition for S. mitis was 0 ± 0mm for OzOO and 18 ± 1.11mm for CHX.

Conclusion: It was concluded that the antibacterial activity of CHX resulted in greater diameter of inhibition zone for the bacteria F. alocis compared to OzOO. The results also indicate growth inhibition for A.a, S. mitis and S. mutans for CHX but no zone of inhibition was noted for these bacteria for OzOO.
