BACKGROUND/AIMS: The varied prevalence of traumatic dental injuries (TDI) in primary teeth around the globe raises a serious knowledge gap in the available literature. The aim of this study was to evaluate the prevalence of TDI in primary teeth and also to evaluate the different factors associated with TDI in primary teeth.
Comprehensive searches were performed in PubMed, Embase, Google Scholar, and The Cochrane Central Register of Controlled Trials with predefined search criteria. The primary outcome was the prevalence of TDI in primary teeth, and the secondary outcomes were the factors associated with TDI in primary teeth. Qualitative analysis was done using the Newcastle-Ottawa scale adapted for cross-sectional studies. The random-effect model was used for meta-analysis, and meta-regression analysis was done to evaluate the heterogeneity between the included studies. Meta-analysis was done using the "meta" package of "R" language. The overall quality of evidence was assessed using GRADEpro GDT software.
A total of 24 cross-sectional studies met the inclusion criteria representing 4876 TDIs in 22 839 children aged between 0 and 6 years old. The overall prevalence of TDI in primary teeth was 24.2% (95% CI: 18.24-31.43, P = 0, I = 99%). Falls contributed the highest number of TDI - 59.3% (95% CI: 41.05-76.40, P < .01, I = 98%) - in primary teeth. The most common type of tooth fracture in primary teeth was an enamel fracture (61.9%), and prevalence of TDI in children with incompetent lip closure was 49.4%.
The prevalence of TDI in cross-sectional studies of primary teeth was 24.2% with very low quality of evidence. Falls contributed the highest number of TDI in primary teeth, accounting for 59.3%. Children with incompetent lip closure have the highest prevalence (49.4%) of TDI in primary teeth.
背景/目的：全球范围内，不同地区乳前牙创伤性牙损伤（TDI）的流行率存在差异，这表明相关文献中存在严重的知识空白。本研究旨在评估乳前牙 TDI 的流行率，并评估与乳前牙 TDI 相关的不同因素。
通过预定义的搜索标准，在 PubMed、Embase、Google Scholar 和 The Cochrane Central Register of Controlled Trials 中进行了全面检索。主要结局是乳前牙 TDI 的流行率，次要结局是与乳前牙 TDI 相关的因素。使用针对横断面研究的纽卡斯尔-渥太华量表进行定性分析。使用随机效应模型进行荟萃分析，并进行荟萃回归分析以评估纳入研究之间的异质性。使用“R”语言的“meta”包进行荟萃分析。使用 GRADEpro GDT 软件评估总体证据质量。
共有 24 项横断面研究符合纳入标准，代表了 22839 名 0 至 6 岁儿童中 4876 例 TDI。乳前牙 TDI 的总体流行率为 24.2%（95%CI：18.24-31.43，P=0，I ² =99%）。跌倒导致 TDI 数量最多-59.3%（95%CI：41.05-76.40，P<.01，I ² =98%）-在乳前牙中。乳前牙中最常见的牙折类型是釉质折裂（61.9%），唇裂闭合不全的儿童 TDI 患病率为 49.4%。
横断面研究中乳前牙 TDI 的流行率为 24.2%，证据质量极低。跌倒导致乳前牙 TDI 数量最多，占 59.3%。唇裂闭合不全的儿童乳前牙 TDI 患病率最高（49.4%）。
