Objectives: Oral malodor originates from VSC from amino acid metabolism by bacteria. Many patients with periodontitis have oral malodor and we therefore tested the relationship between oral malodor and periodontal status.
Methods: A total of 138 adults were investigated using the O’Leary index, L?e & Silness index, formation of periodontal pocket depth, amount of loss for interproximal bone and missing tooth. And measuring the malodor by use of Oral Chroma volatile sulfur compounds. Data were analyzed with a t-test, one-way of variance and multiple regression using SPSS 12.0.
Results: A higher O’Leary plaque index produced higher levels of dimethyl sulfide (p＜0.01). Gingivitis, also tended to increase the concentration of hydrogen sulfide (p=0.095). Deeper periodontal pocket depth (＜4 mm, 4∼5 mm, ≥6 mm), also increased the concentration of hydrogen sulfide (p＜0.05). Methyl mercaptan levels also tended to increase hydrogen sulfide levels (p=0.188). Higher interproximal bone loss (＜50 mm, 50-80 mm, ≥80 mm) increase levels of methyl mercaptan (p=0.05), which was also higher in the missing tooth group than the non-missing tooth group (p＜0.01). For total VSC concentration, a higher loss of interproximal bone increased the risk of halitosis (p＜0.05).
Conclusions: Blocking VSC generation in the periodontal pocket by periodontal therapy could vicious circle of periodontal disease and oral malodor.
