We designed this review to assess the prevalence of malocclusion among 8-15 years old Indian children.
The review protocol was registered in PROSPERO data with register number CRD42020214211. We employed the standard methodological procedures according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Electronic search was done in PubMed database and other sources in 2020 to identify studies. Only studies published in English after January 1, 2000 that assessed prevalence of malocclusion using Dental aesthetic Index (DAI) or Angle's classification of malocclusion were considered for screening. Selection of articles, data extraction and validity assessment were done independently by the two reviewers.
Pooled prevalence of malocclusion is 35.40% (CI:35.37-35.43, 54 studies, 97959 participants). Males had higher proportion of malocclusion (36.20%, CI: 36.12-36.28,33 studies, 40456 participants). 13 years had higher prevalence of malocclusion (33.50%, CI:33.34-33.66, 11 studies, 3366 participants).Prevalence of malocclusion was higher among urban population (32.78%, CI:32.71 32.85,11 studies, 18313 participants). South India showed higher prevalence of malocclusion (39.58%, CI:39.54-39.62, 41 studies, 58645 participants). Prevalence of malocclusion as assessed by mean DAI score was 21.23 (CI:21.14-21.33,11 studies, 12345 participants).
The pooled prevalence of malocclusion among 8-15 years children in India is 35.40% (CI:35.37-35.43,54 studies, 97959 participants).Included studies were heterogeneous in their methods of assessment of malocclusion.
我们开展本综述以评估8至15岁印度儿童错牙合畸形的患病率。
本综述方案已在PROSPERO数据库注册，注册号为CRD42020214211。我们按照系统评价和Meta分析的首选报告项目（PRISMA）声明采用标准方法程序。2020年在PubMed数据库及其他来源进行电子检索以识别研究。仅纳入2000年1月1日之后发表的、使用牙科美学指数（DAI）或安氏错牙合分类法评估错牙合畸形患病率的英文研究进行筛选。两位评审员独立进行文章选择、数据提取和效度评估。
错牙合畸形的合并患病率为35.40%（95%CI：35.37 - 35.43，54项研究，97959名参与者）。男性错牙合畸形比例更高（36.20%，95%CI：36.12 - 36.28，33项研究，40456名参与者）。13岁儿童错牙合畸形患病率更高（33.50%，95%CI：33.34 - 33.66，11项研究，3366名参与者）。城市人口中错牙合畸形患病率更高（32.78%，95%CI：32.71 - 32.85，11项研究，18313名参与者）。印度南部错牙合畸形患病率更高（39.58%，95%CI：39.54 - 39.62，41项研究，58645名参与者）。根据平均DAI评分评估的错牙合畸形患病率为21.23（95%CI：21.14 - 21.33，11项研究，12345名参与者）。
印度8至15岁儿童错牙合畸形的合并患病率为35.40%（95%CI：35.37 - 35.43，54项研究，97959名参与者）。纳入研究在错牙合畸形评估方法上存在异质性。
