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 Pr. intermedia. In this study, saliva from each of 20 healthy subjects was treated with 1% phytoncide from Japanese Hinoki (Chamaecyparis obtusa Sieb. et Zucc.). Surviving salivary bacteria were isolated on blood agar plates and identified by 16S rDNA sequencing. In order to select inhibitory isolates against Pr. intermedia, the isolates from the phytoncide-treated saliva were cultured with Pr. intermedia.
The results were as follows:
1. Among the 200 surviving resident oral bacterium, 148(74.0%) bacterium inhibit the growth of Pr. intermedia on blood agar plates.
2. The 200 surviving resident oral bacterium were 109 Streptococcus salivarius(54.5%), 25 Streptococcus sanguinis(12.5%), 15 Streptococcus mitis(7.5%).
3. Among the 148 bacteria which inhibit Pr. intermedia, Streptococcus salivarius was 85.3%(93/109), Streptococcus sanguinis was 64.0%.(16/25), Streptococcus mitis was 54.3%(8/15), Streptococcus parasanguinis was 66.7%(6/9), and Streptococcus Alactolyticus was 100%(8/8).
Taken together, among the surviving resident oral bacterium, Streptococcus salivarius, Streptococcus sanguinis, Streptococcus mitis were mainly observed to inhibit Pr. intermedia. and they may exert an additional inhibitory activity against the periodontopathic bacterium. Therefore, phytoncide can be used for preventing and ceasing the progress of periodontal disease and halitosis, and thus is expect to promote oral health.
