Reabsorción radicular externa: reporte de tres casos clínicos

Abstract

Background: external root resorption is a physiological or pathological process that causes the loss of dental structure in the external region of the root. If it is pathological, it is due to unwanted and uncontrolled activity of clastic cells, putting the tooth at risk. Its etiology is multifactorial, commonly caused by trauma, parafunctional habits, infection or certain orthodontic treatments. Objective: to report 3 cases of patients diagnosed with external root resorption, with different therapeutic treatments depending on their location and severity. Case reports: the first case involves apical external root resorption in anterior teeth, managed with hygienic and maintenance periodontal therapy; the second case is a tooth with apical external root resorption with advanced loss of architecture of the middle and apical thirds, the treatment was extraction; and the third case is a generalized apical and cervical external tooth resorption in tooth 3.3, with surgical, endodontic and restorative therapy of the tooth and hygienic and maintenance periodontal treatment in the rest of the dentition. Conclusion: it is of utmost importance to perform a complete imaging diagnosis to determine the type and extent of external root resorption. Likewise, to carry out the necessary follow-up imaging during orthodontic treatments, since once this pathology is identified, a comprehensive assessment is required to determine the appropriate treatment, which can range from conservative strategies to extraction.
