title: Clinical factors and socio-demographic characteristics associated with dental trauma in children: a systematic review and meta-analysis.
abstract: OBJECTIVE
  The aim of this systematic review and meta-analysis was to search for scientific evidence regarding the factors associated with traumatic dental injury (TDI) in the primary dentition.
  
  
  METHODS
  An electronic search addressing factors associated with TDI was conducted in the PubMed, ISI, LILACS, Cochrane Library, and Embase databases. Data were extracted and analyzed regarding risk factors, statistical test, effect measures, and study design.
  
  
  RESULTS
  The online search strategy led to the initial retrieval of 2566 articles. After evaluating the titles and abstracts, 24 papers were selected for complete review and data collection. TDI was associated with males (OR: 1.24; 95%CI: 1.09-1.41), inadequate lip coverage (OR: 1.81; 95%CI: 1.50-2.17), overbite (OR: 1.438; 95%CI: 0.94-2.19), and age (1 vs 2 years - OR: 0.47; 95%CI: 0.38-0.58; 2 vs 3 years - OR: 0.78; 95%CI: 0.67-0.91; 3 vs 4 years - OR: 0.82; 95%CI: 0.71-0.95). Overjet and anterior open bite were associated with TDI in the majority of studies.
  
  
  CONCLUSIONS
  Males, older children, and those with inadequate lip coverage, overbite, or overjet are more likely to have TDI in the primary dentition.
