- W4387432992 abstract "This study aims to understand the prevalence and treatment status of dental caries in preschool children aged 3-5 years in China among the past five years.Databases including CNKI, WanFang data, VIP, MEDLINE, EMBASE were systematically searched for the epidemiological literature of dental caries in preschool children in China from 2017 to 2022 for Meta-analysis. Subgroup analysis was carried out by sex, age, geographical region, ethnology, and residence.The Meta-analysis enrolled 27 literatures, including 72 788 preschool children; of which, 38 344 children had dental caries. The merged prevalence of dental caries in preschool children was 59.3% (95%CI: 54.6%-63.9%), and the merged filling rate of caries was 5.7% (95%CI: 2.5%-8.8%). In the subgroup analysis, the merged prevalence rates of caries in children aged 3, 4, and 5 years were 46.9% (95%CI: 42.5%-51.4%), 59.0% (95%CI: 55.1%-62.8%), and 67.3% (95%CI: 62.5%-72.2%), respectively, and the difference was significant. In addition, significant differences were found among different regions. The merged prevalence of dental caries in preschool children was the highest in northwest China (68.6%, 95%CI: 55.5%-81.8%) and the lowest in central China (49.1%, 95%CI: 47.3%-51.0%). The merged prevalence of dental caries was not significantly different among preschool children of different genders, ethnicities, and residence.The prevalence of dental caries in preschool children aged 3-5 years in China is high and continuously increases. The oral health of preschool children should be comprehensively strengthened, and a three-level strategy should be implemented to prevent diseases.目的: 了解近5年中国3~5岁学龄前儿童龋齿患病及治疗情况。方法: 系统检索2017—2022年CNKI、万方数据库、维普数据库以及MEDLINE、EMBASE文献库中中国学龄前儿童龋齿流行病学文献，对符合标准的纳入文献进行Meta分析，并按性别、年龄、地理区域、民族、居住地进行亚组分析。结果: 共纳入文献27篇，总计纳入学龄前儿童72 788例，患龋儿童38 344例。学龄前儿童龋齿合并患病率为59.3%（95%CI：54.6%~63.9%），龋齿合并填充率为5.7%（95%CI：2.5%~8.8%）。亚组分析中3、4、5岁儿童龋齿合并患病率分别为46.9%（95%CI：42.5%~51.4%）、59.0%（95%CI：55.1%~62.8%）、67.3%（95%CI：62.5%~72.2%），不同年龄段间差异具有统计学意义。此外，不同地域间差异也具有统计学意义，其中西北地区学龄前儿童患龋率最高，为68.6%（95%CI：55.5%~81.8%），而华中地区学龄前儿童患龋率最低，为49.1%（95%CI：47.3%~51.0%）。不同性别、民族、居住地间学龄前儿童患龋率差异无统计学意义。结论: 我国3~5岁学龄前儿童龋患现状严重且呈逐年增高趋势，当务之急应全面加强学龄前儿童口腔健康工作，落实疾病三级预防策略。." @default.
