Evaluation of Antimicrobial Effect of Voco Bifluoride 10 and MI paste Desensitizers on Periopathogenic Bacteria

Abstract Background and Aim: Chronic periodontitis is caused by a complex of periopathogenic microorganisms, some of which are more closely related to the active phase of the disease. The aim of this study was to investigate the antibacterial effect of two desensitizing agents voco bifluoride 10 and Mi paste on three common periopathogen bacteria Materials and methods: In this experimental laboratory study, samples of three types of bacteria A.a (Aggregatibacter actinomycetemcomitans), Porphyromonas gingivalis (P.g) and P.I (Prevotella intermedia) were used. From each of the compounds of voco bifluoride 10 and MI paste, 3 disks were prepared. After drying and sterilizing the disks, the quality control operations of the disks were performed and cultured in suitable media and exposed to 37 ° C for 48 hours. According to the halo around each disk and its measurement, the growth or non-growth of bacteria was examined. Data were analyzed using t-test and two-way ANOVA Results: There was no significant difference between the mean diameter of growth inhibition zone of all three types of bacteria A.a, P.g and P.i and the control group under the influence of voco bifluoride 10 and MI (P >0.05). The mean diameter of bacterial growth in the vicinity of MI paste was less than the diameter of bacterial growth in the vicinity of voco bifluoride 10, but this difference was not statistically significant (P >0.05). Conclusion: The use of voco bifluoride 10 and MI paste have no effect on the diameter of the growth inhibition zone of periopathogenic bacteria Key words: Dentin Sensitivity , Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis; Prevotella intermedia,MI Paste
