Abstract

The present study was performed to observe the effect of phytoncide on oral normal microflora and the inhibitory effect of the surviving resident oral bacteria on F. nucleatum. In this study, saliva from each of 20 healthy subjects was treated with 1% phytoncide from Japanese Hinoki (Chamaecyparis obtusa Sieb. et Zucc.). The surviving salivary bacterium were isolated on blood agar plates and identified by 16S rDNA sequencing. In order to select inhibitory isolates against F. nucleatum, the isolates from the phytoncide-treated saliva were cultured with F. nucleatum. The results are as follows: 1. Among the 200 surviving resident oral bacterium, 70(35.0%) bacterium inhibit the growth of F. nucleatum on blood agar plates. 2. Among the 70 bacterium which inhibit F. nucleatum, Streptococcus salivarius was 41.3%(45/109), Streptococcus sanguinis was 28%.(7/25), Streptococcus mitis was 20%(3/15), Streptococcus parasanguinis was 33.3%(3/9), Streptococcus Alactolyticus was 100%(8/8), Streptococcus vestibularis was 28.6%(2/7) and Streptococcus sp. was 50%(2/4). Taken together, among the surviving resident oral bacterium, Streptococcus salivarius, Streptococcus sanguinis, Streptococcus mitis were mainly observed to inhibit F. nucleatum. and they may exert an additional inhibitory activity against the periodontopathic bacterium. Therefore, phytoncide can be used to prevent and cease the progress of periodontal disease, halitosis. Thus it is expected to promote oral health.

본 연구는 편백 피톤치드에 의해 사멸되지 않는 구강 상주균을 분리하고, 이 분리된 세균이 구강 병인균에 대하여 어떠한 영향을 미치는지를 관찰함으로써 편백 피톤치드에 구강 내 세균에 대한 지속적인 이차적 효과를 구명한 실험적 연구이다. 이에 건강한 사람의 타액에 1% 피톤치드를 첨가하여 최종적으로 생존해 있는 200개의 구강 상주균을 확인하여 이를 분석한 후 이들이 치주질환과 입냄새의 중요한 원인균인 F. nucleatum에 대한 억제효과를 관찰하여 다음과 같은 결론을 얻었다. 1. 선택된 200개의 잔존 세균 중, 70개(35.0%)가 F. nucleatum을 억제하였다. 2. F. nucleatum을 억제하는 70개의 잔존 세균 중, Streptococcus salivarius가 41.3%(45/109), Streptococcus sanguinis가 28%.(7/25), Streptococcus mitis가 20%(3/15), Streptococcus parasanguinis가 33.3%(3/9), Streptococcus alactolyticus가 100%(8/8), Streptococcus vestibularis가 28.6%(2/7), Streptococcus sp.가 50%(2/4)로 나타났다. 결론적으로 피톤치드 처리 후의 잔존 세균이 F. nucleatum을 억제함으로써 피톤치드가 구강 건강, 특히 치주질환을 예방하거나 치료하는데 큰 역할을 할 수 있을 것으로 생각하며, 구강 상주균을 건강하게 유지시킨 채로 병인균 만을 억제시킨다는 차원에서 향후 구강내 유익균의 배양가능성을 실용화 할 수 있다고 생각한다.
