Antimicrobial Activity and Cytotoxicity of Mouthwash Prepared from Azadirachta indica and Stevia rebaudiana Extract– An In vitro Study

Abstract

Introduction: Mouth wash are generally utilized as subordinates to oral cleanliness and in the conveyance of dynamic specialists to the teeth and gums. These flushes can impact plaque development and adjust the course of gingival irritation. Azadirachta indica (Neem) was utilized to treat different skin illnesses, as a disinfectant substance and as a natural mouthwash. Stevia rebaudiana can inhibit the growth of microorganisms that are responsible for dental caries. Aim: This study aimed to assess the antimicrobial activity and cytotoxicity from Neem and Stevia based Mouthwash. Materials and Methods: Plant extract was prepared and an antimicrobial and cytotoxic effect was done by considering various parameters. The antimicrobial activity of nanoparticles prepared using plant extract was investigated and the results of the test were described as the standard deviation and analyzed. For the cytotoxic activity, an ELISA plate was used, wherein the mortality rate of the nauplii was estimated with the plant extract mediated nanoparticles at different concentrations. Data’s were statistically analyzed by Spearman correlation through SPSS version 23. Results: Anti-microbial activity showed positive correlation with increase in concentration (r=1). The cytotoxic activity showed negative correlation with the number of live nauplii decreased in the second day when compared to the first day suggesting that the extract has potent cytotoxic activity (r=-1). Conclusion: Neem and Stevia extract helped us to detect the antimicrobial activity and cytotoxic effect on the various species in different concentration levels. The study needs to be evaluated further for isolating the possible compounds to test the effectiveness of antimicrobial activity in the oral cavity of the human body to prevent various diseases.
