Aim: In this study, we aimed to evaluate antibacterial effects of the combined use of cavity disinfectants and antibacterial adhesive agents on the strains Streptococcus mutans, Lactobacillus acidophilus and Enterococcus faecalis. Methods: The evaluation was made using the disk diffusion method. Standard, sterile, empty 5-mm-diameter antibiogram discs in which 15 μL of cavity disinfectant and then 15 μL of adhesive agent were added were placed on agar plates at 2.5–3 cm intervals. The inhibition zone diameters around the discs that were left to incubate for 24–48 hours at 37°C were measured in mm. Data were statistically analyzed with one-way analysis of variance. Results: It was observed that the combination of Oksijenli Su and Clearfil SE Protect Bond had stronger antibacterial effect on S. mutans and E. faecalis while the combination of Cavity Cleanser, which contains chlorhexidine digluconate, and Clearfil SE Protect Bond had stronger effect on L. acidophilus. For all samples, the antibacterial effect at the end of the 48th hour was found to be greater than that at the end of the 24th hour, although the difference was not statistically significant (p>0.05). Conclusion: Our findings indicate that the combined use of cavity disinfectants and antibacterial adhesive agents against S. mutans, L. acidophilus, and E. faecalis in restoration treatments eliminates these microorganisms involved in the formation and development of caries and, as a result, reduces the formation of secondary caries.
