Structured Abstract Authors – Segal GR, Schiffman PH, Tuncay OC Objective – To elucidate possible treatment‐related etiological factors – such as, duration of treatment and apical displacement – for external root resorption. Design – Meta‐analysis of the available English‐language literature. Inclusion & Exclusion Criteria – Papers with a sample size >10, fixed appliances, pre‐ and post‐operative radiographs, and apical displacement recorded were included. History of trauma, prior root resorption and endodontic treatment were excluded. Appropriateness of these selections was tested with a ‘funnel plot’ analysis. Outcome Measure – Correlations between root resorption, apical displacement, and treatment duration. Results – Mean apical root resorption was strongly correlated with total apical displacement ( r = 0.822) and treatment duration ( r = 0.852). Conclusion – The treatment‐related causes of root resorption appear to be the total distance the apex had moved and the time it took.
