It is known that volatile sulfur compounds (VSC) contribute to bad breath. The amount of VSC in the mouth air from patients with periodontal disease were 8 times greater than those who patients without periodontal disease. This study demonstrates that in patients with periodontal disease, 1) the concentration of VSC increased in proportion to the depths of pockets within the gums, 2) 60% of the VSC were produced from the surface of the tongue, 3) the amount of tongue coating was 4 times greater than those without periodontal disease, and 4) the ratio of VSC to tongue coating was at a higher level. Therefore, this study concludes that not only microorganisms, but also the tongue coating and gingival fluid are factors that enhance VSC production in patients with periodontal disease.
