The antiplaque potential of zinc salts has been previously demonstrated. The purpose of the present investigation was to establish the effect of zinc chloride dentifrices on plaque growth and on the concentration of zinc in saliva and plaque. Zinc levels in saliva and plaque were measured by atomic absorption spectrophotometry. Elevated zinc levels were observed in saliva and in plaque for 1 hour after contact with a zinc chloride dentifrice. Increased concentrations of zinc were also observed in plaque residue. Further analysis of data showed that subjects with high rates of plaque growth benefited more from the zinc dentifrices than did those with low rates of plaque growth.
锌盐的抗牙菌斑潜力此前已得到证实。本研究的目的是确定含氯化锌牙膏对牙菌斑生长以及唾液和牙菌斑中锌浓度的影响。通过原子吸收分光光度法测量唾液和牙菌斑中的锌含量。与含氯化锌牙膏接触1小时后，唾液和牙菌斑中的锌含量升高。在牙菌斑残渣中也观察到锌浓度增加。数据的进一步分析表明，牙菌斑生长率高的受试者比牙菌斑生长率低的受试者从含锌牙膏中获益更多。
