Abstract
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.
구강 및 전신 질환이 없는 40명의 치과대학생 자원자를 대상으로 이중맹검법을 시행하여 tea tree, lemon, peppermint essential oil이 함유되어 있는 치약을 사용하게 한 후, 전치 절단면으로부터 3 cm 후방역 구취를 Halimeter를 이용하여 측정한 결과 다음과 같은 결론을 얻었다. 1. 아로마가 첨가된 치약은 구강 내 전반에 걸쳐 지속적인 구취감소효과를 보였다. 2. 아로마를 함유한 치약을 사용한 군에서는 전반적으로 치약 사용 후 2주와 3주에서 구취 증가자 수가 아로마를 함유하지 않은 치약을 사용한 군에 비해 적었다. 3. 구취 증가자의 증가율 평균은 대조군보다 낮았다. 4. 아로마를 함유한 치약을 사용한 군에서는 전반적으로 치약 사용 후 2주와 3주에서 구취 감소율이 대조군에 비해 꾸준히 높게 나타났다. 이상의 결과로, 본 연구에서 사용한 아로마가 함유된 치약은 구취 감소에 효과가 있는 것으로 나타났다. 따라서 구취제거에 효과가 있는 아로마를 사용하여 인체에 부작용이 없는 한계 내에서 치약뿐 만 아니라 구강세척제 등의 구강용품을 개발하여 임상에 적극적으로 사용할 수 있을 것으로 생각된다.
