Abstract

 The aim of this study was to determine the Ca²⁺ levels and pH conditions in saliva that inhibit the generation of volatile sulfur compounds (VSC) by periodontal pathogens, while also suppressing the demineralization of tooth enamel. As causative agents of oral malodor, VSC are generated by the metabolic activity of periodontal pathogens. It is possible that this metabolic activity could be inhibited under acidic conditions, although it carries the risk of enamel erosion. However, the presence of Ca²⁺ can prevent the demineralization of tooth enamel under acidic conditions. Therefore, we investigated the growth of Porphyromonas gingivalis in a pH range of 7.0-3.5, and the levels of Ca²⁺ that prevent the demineralization of tooth enamel in this pH range. Our results enabled us to determine the optimal conditions that inhibit the generation of VSC without demineralizing the tooth enamel by the consumption of food containing calcium and organic acids.
