Materials and Methods: 40 primary molars were obtained from ten patients whose ages ranged between 5 and 11. Dentin samples which were collected before the treatment and after a period of four weeks following the implementation of materials were microbiologically evaluated and material's antibacterial effectiveness were compared. Results: Differences between the antibacterial effectiveness of the materials were found to be statistically significant according to the results of covariance analysis with randomized block design (p<0.05). Antibacterial effectiveness of the groups on S. mutants is Group 2 (ozone therapy)> Group 3(CPB)> Group 1(Dycal). Conclusions: Although CPB, which is an antibacterial self etching system, and ozone therapy do not increase the duration of clinical treatments, they can be efficient solutions for the restorative treatment of primary teeth.
