Abstract:

BACKGROUND: The volatile sulfur compounds (VSCs) is the hotspot in recent years of periodontitis research. There have been few related studies concentrating on the change of three main components of the VSCs by periodontal treatment.
OBJECTIVE: To evaluate the changes of VSCs levels in periodontitis patients before and after periodontal treatment by using a portable gas chromatography.
METHODS: Forty patients with periodontitis in good healthy state were selected according to the organoleptic rating. The levels of three major components of VSCs (H2S, CH3SH, (CH3)2S) were measured before and after periodontal treatment with a portable gas chromatography (OralChroma™). The periodontal therapy includes supragingival scaling, subgingival scaling, root planing and periodontal rinsing.
RESULTS AND CONCLUSION: The periodontal treatment could improve the periodontal conditions of periodontitis patients and significantly reduce the levels of VSCs (P < 0.01). The levels of H2S and CH3SH were reduced by more than 80% and (CH3)2S by more than 50%. H2S had the highest levels among three kinds of gases (P < 0.01). There was a significant reduction of organoleptic rating scores after periodontal treatment compared with before treatment (P < 0.01). A portable gas chromatography can effectively measure the components and concentration of the VSCs, and accurately detect the changes of halitosis. Periodontal treatment is an effective treatment to reduce oral malodour and VSCs levels.
