A total of 297 children aged 5-7 whose first permanent molars appeared in various periods were followed up. Local prevention of caries was carried out in these children with Soviet fluorine lacquer and sealing of fissures and anatomic hollows in molar masticatory surface. The efficacies of these two prevention methods proved to be different. In children whose first permanent molars appeared early or late fissure closing with vitacryl proved to be effective whereas in those whose molars appeared in time both methods were effective.
对297名5至7岁、第一恒磨牙处于不同萌出期的儿童进行了随访。用苏联氟漆对这些儿童进行局部龋齿预防，并封闭磨牙咀嚼面的裂沟和解剖凹陷。结果证明这两种预防方法的效果不同。对于第一恒磨牙萌出早或晚的儿童，用丙烯酸酯封闭裂沟有效；而对于磨牙按时萌出的儿童，两种方法都有效。
