Objectives: The aim of the present study was to test the hypothesis that external apical root resorption (EARR) after six months of orthodontic treatment could be an incidence indicator of EARR after 12 months of treatment in non extraction orthodontic cases. A comparison of EARR between different types of root morphology was also performed. Material and Methods: Periapical radiographs of the upper incisors were obtained prior to treatment (T1) as well as at six months (T2) and 12 months (T3) of non-extraction orthodontic treatment among 47 patients aged 11 years or older. The roots were classified based on anatomic shape. Triangular, pipette-shaped, bent and/or short roots were classified as having a tendency toward EARR, whereas those with a rhomboidal and rectangular shape were classified as.. View More»
