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.
