【摘要】 目的 :使用混合酶制剂去除牙石。方法 :采用已配制混合酶制剂 ,经含漱、刷牙、机械刮治三种方式对比实验。结果 :观察期间牙龈出血均明显减少 ;刷牙、机械刮治减少牙石程度均显著于相应对照侧 (p <0 0 0 1) ,含漱法可抑制牙石生成但不能去除牙石。结论 :该制剂具有明显抑制牙石生长作用 ,适当外力作用能有效去除牙石 ,是化学法洁牙的发展方向更多还原

【Abstract】 s Objective:To use mixed enzyme to clean dental calculus. Methods:The mixed enzyme which had been compunded was exprimented by three ways:gargling、brushing and curetting.[WT5”FZ]Results:[WT5”BZ]All patients abated their gingival blooding.Both brushing and curetting groups significantly decreased dental calculus than their control group([WT5”BX]P[WT5”BZ]<0 001).gargling could prevent development of calculus but didnt clean it.[WT5”FZ]Conclusion;[WT5”BZ]The mixed enzyme could greatly intibit development of calculus and obviously clean dental calculus with suitable force.The study of mixed enzyme will be the direction of chemical dentifrice.更多还原
