Objective: To evaluate the antimicrobial effect of tea tree oil (TTO) (Melaleuca alternifolia) and cinnamon leaf oil (Cinnammomum osmophloeum) against
oral pathogens. This study gives a detail description about the action of TTO and cinnamon leaf oil against pathogens that are responsible for dental
caries. The mouth contains a wide variety of oral bacterial, and only a few specific species of bacteria are believed to cause dental caries: Streptococcus
mutans and Lactobacillus species among them. TTO or Malaleuca is an essential oil with a fresh camphoraceous odor and color ranges from pale yellow to
colorless or clear. It is used for medications as it has an antimicrobial effect. The essential oil of M. alternifolia exhibits antimicrobial activity against a wide
range of Gram-positive and Gram-negative bacteria, yeasts, and fungi. Cinnamon oil contains cinnamaldehyde which possess the strongest antibacterial
activity. Since essential oil has a very good antimicrobial effect, it is used against the action of oral pathogens involved in dental caries.
Methods: Cinnamon leaf oil and TTO disc diffusion method is used.
Result: The results obtained from our study shows that the two essential oils have got a very good antibacterial activity against S. mutans.
Conclusion: From this study , we conclude that herbal product have a very good anti bacterial effect. So herbal products can be introduced for dental
Keywords: Cinnamon oil, tea tree oil, dental caries, disc diffusion, S. Mutans, herbal product.
