Abstract :
Apical root resorption (ARR) is a physiological course associated with the erosion of cementum or dentin, which results in the reduced root apex of a tooth. This condition represents an irreversible loss of tissue at the tip of the tooth's root and is considered the primary abominable adverse effect associated with orthodontic tooth movement. Factors that have been identified as potentially impacting the extent of apical root resorption include age, gender, nutritional status, genetic factors, the form of orthodontic device used, the pressure applied during treatment, the decision to extract or not extract teeth, the period of treatment, and the amount a tooth or teeth are moved during orthodontic correction.Objective: The main reason for this study was to see if a discrepancy persists in the extent of ARR during orthodontic treatment between PEA and CAT.Data Sources: A search of pubmed Medline, Cochrane Central Register of Controlled Trials, and Google Scholar was performed and the studies that have evaluated the amount of apical root resorption using PEA or CAT were selected for this systematic review. Database research, elimination of duplicate studies, data extraction, and risk of bias were performed by authors independently and in duplication.
