摘要

摘要: 目的观察无龋3岁儿童干预1年后龋活性变化与新龋发生情况的关系，为今后龋病的分级管理提供参考依据。方法 2020年9月基线时选择张家港市9所幼儿园的808名无龋3岁儿童为研究对象，进行口腔检查和龋活性检测，高龋活性组3个月涂氟1次，中、低龋活性组6个月涂氟1次，干预1年后，2021年9月对714名儿童再次进行口腔检查和龋活性检测，分析不同龋活性变化组间儿童新增患龋情况的差异。结果干预1年后新增患龋儿童200名，新龋发生率28.0%，龋均为0.0(0.0, 1.0)。男女童患龋率分别是22.5%，34.1%，龋均分别为0.0(0.0, 0.0)，0.0(0.0±1.0)，女童的患龋率和龋均高于男童，差异均有统计学意义(χ²/Z值分别为11.83，3.61，P值均 < 0.05)。龋活性不变、降低、升高3组间的新龋发生率分别为29.6%，14.3%，35.6%;龋均分别为0.0(0.0，1.0)，0.0(0.0, 0.0)，0.0(0.0, 1.0)，3组间差异均有统计学意义(χ²/Z值分别为20.68，21.04，P值均 < 0.05)。涂氟干预会影响龋活性变化，随着干预次数的增加，龋活性降低的人群占比升高，差异有统计学意义(χ²=80.55，P < 0.05)。但不同干预频率组间新龋发生率和龋均的差异无统计学意义(χ²/Z值分别为0.83，0.61，P值均>0.05)。结论龋活性降低可以减少新龋发生率，增加涂氟干预频率可降低龋活性。

Abstract: Objective To observe the relationship between the changes of caries activity and the incidence of new caries in 3 years old caries-free children after 1 year of intervention, and to provide reference for grading management of caries. Methods At baseline in September 2020, 808 caries-free 3-year-old children from 9 kindergartens in Zhangjiagang were selected for oral examination and caries activity detection. After one year of fluoride treatment, fluoride was applied once every 3 months in the high caries activity group and once every 6 months in the moderate and low caries activity groups, a total of 714 caria-free children aged 3 years were followed up for oral examination and caries activity detection in September 2021. The differences of new caries in different caries activity changes groups were analyzed. Results There were 200 new caries (28.0%) and dmft was 0.0(0.0, 1.0). The prevalence of caries (34.1%) and dmft 0.0(0.0, 0.0) in girls were higher than in boys(22.5%)[0.0(0.0, 1.0)], the differences were statistically significant(χ²/Z=11.83, 3.61, P < 0.05). The incidence of new caries among unchanged, decreased and increased of caries activity group was 29.6%, 14.3% and 35.6%, respectively. The average number of dmft was 0.0(0.0, 1.0), 0.0(0.0, 0.0), 0.0(0.0, 1.0), respectively. There were significant differences in the incidence of new caries and dmft among the three groups(χ²/Z=20.68, 21.04, P < 0.05). Fluorinated intervention could affect the changes of caries value. With the increase of the number of interventions, the proportion of children with reduced caries activity increased(χ²=80.55, P < 0.05). However, there were no significant differences in the incidence of new caries and dmft among groups with different intervention frequencies(χ²/Z=0.83, 0.61, P < 0.05). Conclusion Reduction of caries activity through fluoride application could be future approach for caries control among children.
