Oral malodorous compounds including hydrogen sulfide (H2S) are causative agents of periodontitis because the toxicities are similar to that of cyanate. Previous studies demonstrated that volatile sulfur compounds (VSCs) were highly toxic to periodontal tissues, causing a large reduction in the amount of collagen in human gingival fibroblasts and extracellular matrix as well as, for example, apoptosis, immunologic responses, and matrix metalloproteinase production. The objective of this study was to determine the effect of H2S on the proliferation of osteoblasts and a signaling transduction pathway through the mitogen-activated protein kinase (MAPK).
