摘　　要：目的评价喷砂法处理牙面对恒磨牙窝沟封闭保留时间的影响.方法采用随机分组对照实验,实验组在窝沟封闭前用喷砂法处理牙面,对照组用传统慢机清除牙面色素菌斑,分别观察两组0.5a、1a、2a后窝沟封闭保存率,并进行统计学分析.结果封闭后6个月,两组保存率差异无统计学意义.1a、2a后实验组保存率分别达到97.8%,95.5%,明显高于对照组90.4%,81.8%,差异有统计学意义(P<0.05).结论与传统的慢机法处理牙面比较,喷砂法处理牙面能延长恒磨牙窝沟封闭保留时间,值得临床推广使用.Objective To observe the influence of kavo prophyflex 3 applied in sealant technique on sealing the permanent teeth fissure. Methods Patients with permanent teeth fissure were divided randomly into contol group and experiment group. Kavo prophyflex 3 was applied in first permanent molars of patients in experiment group, and conventional clear technique was applied in first permanent molars of patients in contol group. Sealant retention rates were compared 0.5 a, 1 a and 2 a after treatment between eontol group and experiment group. Results There was no significant difference in the sealant retention rate 6 months after treatment between the contol group and experiment group. However, significant difference was observed la and 2 a after treatment between the contol group and experiment group （P 〈 0.05 ）. Conclusion Sealant with kavo prophyflex 3 is more effective than conventional sealant technique in prolonging the sealant retention time.
