目的:探讨年轻恒牙应用不同方法进行窝沟封闭的临床效果。方法:将55例7~12岁的儿童随机分为两组,分别采用常规清洁方法后进行窝沟封闭,及常规清洁方法配合去釉质后进行,观察其疗效。结果:第12个月复查时,常规清洁方法总脱落率为3.47%,常规清洁方法配合去釉质总脱落率为2.00%。两种方法相比较差异无统计学意义(P>0.05),第18个月复查时,常规清洁方法总脱落率为10.30%,常规清洁方法配合去釉质总脱落率为4.23%。两种方法相比较差异有统计学意义(P<0.05)。结论:常规清洁方法配合去釉质后进行窝沟封闭提高了材料的保留率,能够更为有效地预防年轻恒牙窝沟龋的发生。
Objective: To investigate the clinical effect of different methods of pit and fissure occlusion in young permanent teeth. Methods: Fifty-five children aged 7 to 12 years old were randomly divided into two groups. The fissure sealant was closed after routine cleaning method, and enamel was removed by routine cleaning method. The curative effect was observed. Results: At the 12th month of review, the total excretion rate of routine cleaning method was 3.47%. The total enamel removal rate of conventional cleaning method was 2.00%. There was no significant difference between the two methods (P> 0.05). At the 18th month, the total excretion rate of the routine cleaning method was 10.30%. The total enamel removal rate of the conventional cleaning method was 4.23%. The difference between the two methods was statistically significant (P <0.05). Conclusion: Conventional cleaning method combined with enamel for pit and fissure sealant improves the retention rate of materials, and can prevent the occurrence of carious deciduous caries in young permanent teeth more effectively.
