目的：通过临床实验评价１０％氟钼酸铵溶液预防和抑制乳牙龋的作用。方法：用１０％氟钼酸铵溶液（实验组）和０９％生理盐水（对照组）涂擦牙面；实验前、后统计幼儿乳牙患龋情况并进行统计学分析。结果：（１）二年后幼儿患龋率实验组明显低于对照组（Ｐ＜０．０５）；（２）患新生龋的人数和牙数，实验组均明显低于对照组（Ｐ＜０．０５）；（３）与对照组比１０％氟钼酸铵溶液有明显地抑制牙本质龋的作用（Ｐ＜０．０２）。结论：１０％氟钼酸铵溶液对乳牙龋不仅有预防作用，而且对已形成的龋齿有抑制其发展的作用，对牙本质龋的抑龋效果更加突出。
OBJECTIVE: To evaluate the effect of 10% ammonium fluoromolybdate solution on the prevention and suppression of deciduous caries in clinical trials. Methods: The tooth surface was rubbed with 10% ammonium fluoromolybdate solution (experimental group) and 0.9% saline solution (control group). The dental caries in young children were statistically analyzed before and after the experiment. Results: (1) The caries prevalence rate of children in two years was obviously lower than that in control group (P <0.05); (2) The number of new caries and number of teeth in experimental group were significantly lower than those in control group (P < 0.05). (3) Compared with the control group, 10% ammonium fluoromolybdate solution significantly inhibited the dentine caries (P <0.02). CONCLUSION: Ammonium fluoromolybdate solution not only has preventive effect on deciduous teeth caries, but also inhibits the development of already formed deciduous caries and inhibits dentine caries.
