Abstract

The results suggest that the effectiveness of sulfates in prolonging the antibacterial activity of teeth treated with chlorhexidine gluconate is related to the acidity and concentration of the sulfate solutions. The acidity may contribute to the effectiveness by modifying the tooth surface for enhanced reaction with sulfate ions. It is suggested that during the priming process bonded crystals of calcium sulfate develop which become transformed by treatment with chlorhexidine gluconate to relatively insoluble chlorhexidine sulfate.

摘要

结果表明，硫酸盐在延长用葡萄糖酸氯己定处理过的牙齿的抗菌活性方面的有效性与硫酸盐溶液的酸度和浓度有关。酸度可能通过改变牙齿表面以增强与硫酸根离子的反应而有助于提高有效性。有人提出，在预处理过程中会形成硫酸钙的键合晶体，在用葡萄糖酸氯己定处理后，这些晶体转变为相对不溶的硫酸氯己定。
