Background: The emergence of resistance, side effects, and the high cost of drugs indicates a need for other therapeutic alternatives with similar properties but fewer side effects. Purpose: . Materials and Method: was assessed using the agar well diffusion and microbroth dilution tests. Water and chlorhexidine were considered as the negative and positive control groups. Kruskal-Wallis and Mann-Whitney tests were used to compare the size of the diameter of the non-growth halo. Data analysis was obtained using SPSS V.22, and the significance level was considered less than 0.05. Results: = 0.05). The findings of the microbroth dilution test showed that atorvastatin and nano-atorvastatin had the minimum inhibitory concentration of 0.039 and 0.002 µg/ml, respectively. Conclusion: . Therefore, these substances can be used as an additional drug in treating periodontal diseases.
