The prevalence of traumatic dental injuries in deciduous teeth: A systematic review and meta-analysis.
Description
The present systematic review and meta-analysis was aimed to evaluate the prevalence of traumatic dental injuries (TDI) in deciduous teeth and also to evaluate the different factors associated with TDI in deciduous teeth. The comprehensive searches were made in PubMed, EMBASE, Google Scholar, and The Cochrane Central Register of Controlled Trials with predefined search criteria. The primary outcome was the prevalence rate and secondary outcomes were the factors associated with TDI in deciduous teeth. The qualitative analysis was done using the Newcastle-Ottawa scale adapted for cross-sectional studies. The random-effect model was used for the meta-analysis and meta-regression analysis was done to evaluate the differences in study methodologies and geographic variations. The Meta-analysis was done using the “meta” package of R language. The overall quality of evidence was assessed using GRADE pro GDT software. A total of 16,774 TDI were observed in 3,24,452 children within the age group of 0-6 years from 62 included articles. The overall prevalence of TDI in primary teeth was 18.8% [(95% CI: 16.39 - 21.34), p = 0, I2=100%]. Falls contribute to the maximum number of TDI 57.27% [(95% CI: 47.75; 66.54), p < 0.01, I2=98%] in deciduous teeth. The most common type of tooth fracture in the primary teeth was enamel fractures 35.73% [(95% CI: 26.99; 44.97), p =0, I2=99%] followed by the luxation injuries. The prevalence of TDI in children with any predisposing factor was 41.17% [(95% CI: 37.02; 45.39), p <0.01, I2=88%]. The prevalence rate of traumatic dental injuries in primary teeth was 18.8 %. Falls contribute to the maximum of TDI in primary teeth accounting for up to 57.2 %. Children with incompetent lip closures have the highest prevalence rate (50.7%) of TDI in primary teeth.
