Rare clinical case of tooth root external resorption as a delayed post-traumatic complication Artak Heboyan
Presented clinical case reveals some problems concerning the detection, diagnostics and
treatment of tooth root external resorption. Root resorption of permanent tooth (internal and external) is assessed as pathological process, caused by different factors both general (cardiovascular diseases, endocrine disorders, some infections, such as Hepatitis C, Hepatitis B virus, human immunodeficiency virus. etc.) and more often local (traumas, delayed complications after caries treatment, local metabolic disorders in the pulp and periodontium).
This clinical case presents the tooth root apex resorption as a delayed post-traumatic complication. The lesion of progressed resorption was revealed six years after dentoalveolar trauma. Over these years the patient didn’t have any clinical manifestations. The area of resorption was revealed accidentally during the clinical X-ray examination, specifically by conical beam computed tomography that enables three-dimensional area examination and more precise assessment of pathological lesion location and distribution directions. Pathohistological study was also carried out in
order to clarify the diagnosis, thus preliminary diagnosis was eventually confirmed. The color of tooth crown was changed. The choice of treatment method was conditioned by the resorption type, its etiologic factor, direction of pathological process distribution and lesion size. The treatment is often complex, long-lasting, expensive and the results are unpredictable. Tooth extraction is the only treatment in some cases. Conservative approach through endodontic intervention is possible if tooth root resorption is revealed at early stage and its sizes are permissible. In this clinical case the surgical strategy was conditioned by the large volume of tooth root resorption, thus tooth extraction was performed. After the alveolar bone healing, the space of missing tooth was restored by metal ceramic bridge, fixed on adjacent teeth after endodontic treatment.
