【摘要】 目的了解氟化泡沫3～6岁儿童防龋效果。方法本文采用防龋氟化泡沫,一年内使用两次,对1171名3～6岁儿童进行龋齿预防。结果发现刚萌出的恒牙实验前后未见龋病波及。试验组乳牙龋患率基本控制,实验前后(36.64%,37.06%)无差异(x2=0.459,P>0.01)。实验前龋患率试验组(36.64%)与对照组(37.73%)无差异(x2=0.0738,P>0.05)实验后,对照组龋患率(47.37%)高于试验组(37.06%),两组之间存在差异(x2=7.333,P<0.01)。乳牙龋齿新发病率对照组(23.02%)高于试验组(5.98%)(x2=42.5456,P<0.01)。龋均,实验前后绝对差值对照组(0.16)高于实验组(0.080)。其试验结果与文献报导一致。结论氟化泡沫对3～6岁组儿童的龋病预防是有效的。更多还原

【Abstract】 Objective To prevent the dental caries.Methods fluorinated anticarious bubbles were applied on 1171 children aging from 3 to 6 twice a year.Results Pernanent teeth were not affected by dental caries before and after the experiment. In terms of the dental caries incidences of deciduous teeth, there were no difference before and after the experiment (36.64%,37.06% x2=0.459, P>0.01) in the exprimental group. Before the experiment, there was no difference between the exprimental group and the control group. (36.64%,37.73%, x2=0.0738,P>0.05).After the experiment, the dental caries incidence in the control group (47.37%) was higher than that of the control group (37.06%),(x2=7.333, P<0.01).The new dental caries incidence of deciduous teeth in the experimental group (23.02%) was higher than that of the control group (5.98%) (x2=42.5456,P<0.01) As for the average dental caries incidence,there was a big margin between the control group (0.16) and the experimental group (0.080). The experiment results were consistent with literature reports.Conclusion The prevention of dental caries with fluorinated bubbles is effective to the children aging from 3 to 6.更多还原
