Manoj Kumar KR and Gopinath P

The human dental cavity is colonized with large groups of aerobic and anaerobic bacterial species. Enterococcus faecalis as a nosocomial pathogen can cause serious infections that are frequently isolated (30-90%) from root canal treated patients.Peppermint oil has antibacterial activity against both gram positive and gram negative bacteria. It also possesses antiviral and antifungal activities.Thus, this study is to determine the antibacterial activity of peppermint oil against isolates of Enterococcus faecalis from dental caries populations.The MIC of peppermint oil was appeared to be 0.125% for E. faecalis.The peppermint oil is found to have antibacterial activity against E. facecalis. However, the studies on toxic and irritant properties of essential oils are imperative, especially when considering any new products for human administration.
