Children rinsed twice daily with one of two concentrations of calcium glycerophosphate or a placebo. Plaque was collected at two-week intervals for eight weeks, and Löe and Silness Indices determined. Results indicate a lower index rating and a higher phosphorus content for experimental groups than for the control at the four-week examination.
儿童每天用两种浓度的甘油磷酸钙或一种安慰剂漱口两次。每隔两周收集牙菌斑,持续八周,并测定洛氏和西尔斯指数。结果表明,在四周检查时,实验组的指数评分低于对照组,磷含量高于对照组。
