This review comparing orthodontically induced external apical root resorption (EARR) in root-filled teeth and vital pulp teeth included 11 mainly retrospective studies . The findings suggest less EARR in root-filled teeth but the evidence is of very low certainty.

This Cochrane review was seeking to identify RCTs of interventions for the management of external root resorption in permanent teeth. No published trials were identified, so clinicians must decide on the most appropriate means of managing this condition according to their clinical experience with regard to patient-related factors.

Review suggests that autotransplantation of teeth with complete root formation have favourable outcomes

shutterstock_4350574

Autotransplantation of teeth has been carried out for many years and the 1990s saw clarification of the prognosis and risk factors together with proposed standard surgical procedures.  The aim of this review was to assess the outcomes of autotransplanted teeth with complete root formation and the effects of various influencing factors. Searches were conducted in [read the full story…]

Orthodontically induced external apical root resorption (OIEARR) has been classified as surface resorption caused by loss of cementum.  Usually this is superficial and unidentifiable radiographically but if this occurs apically it can be seen as shortening of the tooth.  Typically OIEARR is less than 2mm and clinically insignificant. OIEARR greater than 4mm is severe and [read the full story…]
