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.
本研究旨在了解过去五年中国 3-5 岁学龄前儿童龋齿的流行状况和治疗现状。
系统检索中国知网、万方数据、维普、MEDLINE、EMBASE 等数据库，收集 2017 年至 2022 年中国学龄前儿童龋齿的流行病学文献，进行 Meta 分析。根据性别、年龄、地理位置、民族和居住地进行亚组分析。
Meta 分析纳入 27 篇文献，共 72788 名学龄前儿童；其中 38344 名儿童患有龋齿。学龄前儿童龋齿总体患病率为 59.3%（95%CI：54.6%-63.9%），龋齿充填率为 5.7%（95%CI：2.5%-8.8%）。亚组分析显示，3 岁、4 岁和 5 岁儿童龋齿患病率分别为 46.9%（95%CI：42.5%-51.4%）、59.0%（95%CI：55.1%-62.8%）和 67.3%（95%CI：62.5%-72.2%），差异有统计学意义。此外，不同地区之间也存在显著差异。中国西北地区学龄前儿童龋齿患病率最高（68.6%，95%CI：55.5%-81.8%），而中部地区最低（49.1%，95%CI：47.3%-51.0%）。不同性别、民族和居住地的学龄前儿童龋齿患病率差异无统计学意义。
中国 3-5 岁学龄前儿童龋齿患病率较高且呈持续上升趋势。应全面加强学龄前儿童口腔健康，实施三级防病策略。
