摘要:

目的 评价儿童六龄牙窝沟封闭4年后的效果。 方法 对广州市海珠区南石头街5所小学二年级学生进行入校检查,并为符合适应证的儿童六龄牙实行诊室内窝沟封闭,4年后入校回访,检查其封闭剂保留情况和患龋情况。 结果 受试儿童508人,共检查六龄牙1 231颗,其中符合窝沟封闭适应证1 012颗,符合适应证中未行封闭的279颗,已封闭的733颗,应封未封率为27.57%。窝沟封闭4年后,六龄牙的封闭剂保留率为57.16%;患龋率比较,已封闭组为9.82%,未封闭组为15.77%,2组比较差异具有统计学意义(χ 2 = 7.045,P = 0.008),已封闭组龋降低率为37.73%;另外,浅窝沟组的患龋率为7.76%,已封闭组与之比较其差异无统计学意义(χ 2 = 0.844,P = 0.358)。 结论 六龄牙窝沟封闭4年后观察,其龋降低率明显。

Abstract:

Objective Assessing the effect of pit and fissure sealing on children’mandibular first molar in four years follow-up. Methods The second grade pupils of five primary schools in Guangzhou were given pit and fissure sealing, 733 teeth were performed pit and fissure sealant. The retention rate of the sealant and caries incidence of the mandibular first molar were analysed in four years follow-up. Results In four years follow-up, the retention rate of mandibular first molar was 57.16%. In terms of the caries incidence, the sealing group was 9.82%, while the unsealing group was 15.77%(χ 2 = 7.045, P < 0.05). The decrease rate of caries in the sealing group was 37.73%, the caries incidence for the shallow pit and fissure group was 7.76%, no statistical differentce could be found two groups (χ 2 = 0.844,P = 0.358). Conclusion Caries incidence of mandibular first molar obviously decreased 4 years later after the pit and fissure sealing.

Key words: Mandibular first molar, Pit and fissure sealing, Caries, Retention rate of sealant, Decrease rate of caries
