Introduction: Streptococcus mutans is a facultatively anaerobic, Gram-positive coccus (round bacterium) normally found in the human oral pit and is a noteworthy supporter of tooth decay. It is a piece of the “streptococci” (plural, and non-italic lowercase), a casual general name for all species in the sort Streptococcus. An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compound from plants. Essential oils are also known simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is “essential” in the sense that it contains the “essence of” the plant’s fragrance – the characteristic fragrance of the plant from which it is derived and is used for many other medical uses such as in treating bacterial and fungal infections as well as in aromatherapy. Aim: The aim of the study is to compare and analyze the antibacterial activity of five essential oils against S. mutans. Materials and Methods: The test microorganisms S. mutans was obtained from the microbiology department of Saveetha Dental College and stored at 4°C. The essential oils are lemon grass oil, cypress oil, orange oil, Brahmin oil, and pepper oil. Results: The lemon grass showed more antibacterial activity than the other oils used and showed a zone of inhibition of 50 mm longest than the other activity showed. Conclusion: The study concludes that among all the oils lemon grass showed significant length in the zone of inhibition area of 50 mm. There by proving a good antibacterial activity against S. mutans.
