Since many reports for the influence of the essential oils on the oral microorganism were presented, it is important to use the essential oils in clinical field. At the present day which emphasized the quality of life, oral malodor is one of the serious problems, so we need to try to decrease of oral malodor. This study was designed to make on evidence of the effect of essential oils to oral malodor clinically and to develop on effective treatment for oral malodor by using the dental paste which contains essential oils. 40 dental students volunteered to participate in this study and double blind test was used. At the beginning, all subjects were measured their morning malodor prior to this experiment, at the 3cm posterior to their incisal edge of the oral cavity by Halimeter(Interscan Co. Chatsworth, CA). After that we divided the students in half into two groups A and B. We have supplied different tooth pastes, dental paste A and B, to two groups respectively. The dental paste B contained essential oils which are tea tree, lemon and peppermint. All students used different tooth pastes everyday for 3 weeks. And all students were measured their morning malodor every week with the same method by using Halimeter. This study was resulted that ; 1. The dental paste which contains essential oils has continuously decreased the morning malodor during the whole period of experiments. 2. The number of students with increase in their morning malodor was generally decreased in the group B who used the toothpaste which contains essential oils, compared with the group A who used the toothpaste which didn't contain essential oils on the 2nd and 3rd week of the experiment. 3. In the group B, the average data on increasing rate of morning malodor was less than in the group A. 4. In the 2nd and 3rd week of the experiment, the data on the rate of morning malodor of the group B was generally decreased continuously compared with the group A. These results have statistically significance under 95% confidence interval of the difference.(p$\leq$0.05) As the result, the toothpaste which was containing essential oils was effective in decreasing the morning malodor.
