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 update of different materials used for retrograde root filling in children and adults requiring retrograde filling included 8 RCTs. However the studies are all at high risk of bias so provide insufficient evidence for the benefits of any one material.

This large RCT involving 308 patients found that using 1.3% NaOCl was associated with less intense and less frequent post-endodontic pain than 5.25% NaOCl in mandibular molars with nonvital pulps treated in two visits.

This review of post-retained crowns on endodontically treated teeth included 9 RCTs. Findings suggest that that the number of remaining coronal walls and the use of posts are key factors for the success/ survival of these restorations. However the quality of the available evidence is low.

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…]
