External root resorption, case reports three cases follow up

Abstract

Background: external root resorption is a physiological or pathological process that produces 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 it at risk. to the tooth. The etiology is multifactorial, commonly caused by trauma, parafunctional habits, infection or orthodontic treatments. Objective: to report 3 cases of patients diagnosed with external root resorption, with different therapeutic options 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, which treatment was extraction; and the third case is a generalized apical and also cervical in tooth 3.3 external root resorption, with surgical, endodontic and restorative therapy of this 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, carry out the relevant imaging follow-ups during orthodontic treatments, since once this pathology is identified, a comprehensive assessment is required to define the relevant treatment for each case, which can range from conservative strategies to extraction.
