In order to confirm the effect of improving oral environment by using high-precision hypochlorite water (research product) for 4 consecutive weeks.
Efficacy
clinical parameters (gingivitis index(GI:Lee & Sillness, 1963), dental plaque index (PlI:Silness & Loe, 1964))
1. comprehensive analysis of flora in saliva (occupancy and diversity of each species by next generation sequencer)
2. caries-associated bacteria numbers (total streptococci, S. mutans, lactobacilli)
3. Number of periodontopathogenic bacteria (A.actinomycetemcomitans, P.gingivalis, P.intermedia, T.forsythensis, T.denticola, F.nucleatum)
4. Tongue Coating Index (photography)
5. halitosis measurement (oral chroma: hydrogen sulfide, methyl mercaptan, dimethyl sulfide)
