摘要： 目的:调查乳磨牙龋坏对前磨牙萌出年龄的影响。方法:选择 2010年时5~6岁的儿童,检查乳磨牙情况至其替牙期结束,分为无龋组、浅龋组和深龋组;建立人群的基线资料,建立个人口腔健康档案,且在2010~2017年至少完成4次以上学校口腔检查。应用SPSS 20.0软件包进行结果分析。结果:2010~2017年,共调查了1549名儿童,其中男生762名,女生787名;合计调查上第-乳磨牙1473颗、上第二乳磨牙1616颗、下第一乳磨牙1851颗、下第二乳磨牙1686颗。当上下颌乳磨牙患深部龋时,前磨牙的替换时间均较无龋及浅龋情况下提前,平均提前半年以上,差异有统计学意义(P<0.05)。结论:儿童的龋病预防和干预是关键,尤其是乳磨牙的龋坏需及早治疗,以维持牙列的完整性和乳恒牙的正常替换。

Abstract: Objective: To learn the effect of decidous tooth decay on the eruption time of premolar. Methods: Children aged 5-6 were selected in 2010. Decidous teeth were examined until the permanent teeth were completed. They were divided into caries free group, shallow caries group, and deep caries group. The children completed oral examinations at least 4 times during 2010-2017. The baseline data were obtained and a personal oral health record was established. The results were analyzed with SPSS20.0 software package. Results: Between 2010 and 2017, 1,549 children were surveyed, including 762 boys and 787 girls. A total of 1473 maxillary first decidous molars, 1616 maxillary second decidous molars, 1851 mandibular first decidous molars, and 1686 mandibular second decidous molars were investigated. When the decidous molars were deep caries, the replacement time of the premolar was earlier than that without caries or shallow caries, and the average time was more than half a year earlier. The difference was statistically significant (P<0.05). Conclusion: Students of dental caries prevention and intervention is the key. Caries in decidous teeth need early treatment to maintain the integrity and the normal replacement of the teeth.
