Abstract:
External apical root resorption(EARR)is one of the most common side effects of orthodontic treatment.Contact with sur-rounding anatomical structures during tooth movement is a significant cause for EARR.However,a comprehensive review of factors leading to EARR due to direct contact of surrounding anatomical structures with the root apex during orthodontic treatment is still lac-king.This review summarizes the anatomical structures related to EARR,including alveolar bone,incisive canal,maxillary sinus,ad-jacent teeth,and bone islands.Alveolar bone,incisive canal,and adjacent teeth can directly cause EARR during orthodontic treat-ment,while the impact of the maxillary sinus and bone islands on EARR has not been discovered so far.Analyzing the anatomical structures around the tooth roots can help develop more effective methods to prevent or reduce the occurrence of EARR during orthodon-tic treatment.
