Author(s): Chanchal Katariya*, Sankari Malaiappan
Aim: The aim of the current study is to assess the antimicrobial activity of aqueous and ethanol mint extract against anaerobic and aerobic bacteria found in subgingival plaque of chronic periodontitis patients. Materials and method: Fresh mint leaves were collected, washed, dried and then finely powdered. Aqueous extract was prepared using 50mg of mint powder, mixed with 100ml of distilled water. The mixture was boiled till it reached 10ml and was filtered using filter paper. Ethanol extract was prepared using 50mg of mint powder and was mixed with 50ml of ethanol. The mixture was left for 24 hours with periodic shaking and was filtered. The prepared extracts were compared with chlorhexidine in aerobic and anaerobic microbial culture. Results: Chlorhexidine showed maximum zone of inhibition against both aerobic and anaerobic bacteria of 23mm and 20mm respectively. Followed by ethanolic extract of mint with zone of inhibition against both aerobic and anaerobic bacteria of 17mm and 16mm respectively. Zone of inhibition against aerobic and anaerobic bacteria is 11mm and 9mm respectively. Conclusion: These results supports a notion that mint extract can be used for treatment of periodontal diseases.
