PECULIARITIES OF EXTERNAL APICAL ROOT RESORPTION ASSOCIATED WITH ORTHODONTIC TOOTH MOVEMENT IN ROOTS OF VARYING APICAL MORPHOLOGY AND ITS QUANTITATIVE AND QUALITATIVE SYSTEMATIZATION

Apical root resorption is an adverse consequence frequently observed in orthodontic treatment, resulting in the irreversible loss of dental structure. The clinical diagnosis of this condition primarily relies on routine radiographic assessments, including periapical and panoramic radiographs (Dudic A. et al, 2009). The sagittal section allows visualization distinctly of the resorption lesions on the labial and lingual surfaces of the root. Our objective was to assess, the quantitative and qualitative rates of tooth root apical resorption resulting from orthodontic treatment and to investigate the correlation between root morphology and the configuration of the resorption lesions. The examination of 46 resorbed teeth revealed various types of resorption. The introduction of three-dimensional imaging has introduced the possibility of an accurate quantitative evaluation, allowing for the differentiation of root resorption levels across various root surfaces, which is a preventive measure to prevent distant root resorption and tooth loss in the process of orthodontic treatment.
