The prevalence of traumatic dental injuries in primary teeth: A systematic review and meta‐analysis

Abstract

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. Materials and Methods 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. Results 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, I2 = 99%). Falls contributed the highest number of TDI ‐ 59.3% (95% CI: 41.05‐76.40, P < .01, I2 = 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%. Conclusion 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.

Association of the prevalence and severity of untreated traumatic dental injuries with body mass index among Brazilian preschool children

“…The literature shows that TDI in the primary dentition is more likely to occur in males, 23 an association that differs from the results of the present findings. This divergence may be explained by changes in customs over time.…”

Intrusive luxation of permanent upper central incisor into the nasal cavity: A case report

“…Dental trauma in young patients is more common in the deciduous dentition of males, and the most frequent etiology is falling from their height. 17,18 The tooth can be displaced to any part of the human body. The most common sites are the alveolar bone of the maxilla, oral cavity, sinus, stomach, and lung.…”

Süt dişlenme döneminde meydana gelen travmatik dental yaralanmaların daimi dişler üzerindeki etkileri

“…Literatürde süt dişlenme döneminde görülen TDY'lerin prevalansının erkeklerde kızlara göre daha yüksek olduğu bildirilmekle beraber [21,[35][36][37], bazı çalışmalarda TDY'lerin erkekler ve kızlar arasında eşit veya benzer prevalansta görüldüğü belirtilmiştir [38,39].…”

“…TDY'lerin hem süt hem de daimi dişlenme döneminde yaygın olarak görülmesine rağmen, süt dişlerinin değişeceği ve dolayısıyla tedavi gerektirmeyeceği düşüncesi ile ebeveynler süt dişlerine daha az önem vermektedir. Süt dişlerinde meydana gelen TDY'lerin ebeveynler tarafından ihmal edilmesi nedeniyle takip eden daimi dişlerde gelişimsel bozukluklara neden olabileceğinin vurgulanması gerekmektedir [37]. Süt dişlenme döneminde meydana gelen TDY'ler sonrası daimi dişlerde gelişimsel bozuklukların görülme sıklığı %12-74 arasında değişmektedir [40][41][42].…”
