Comparative study of the alveolar resorption after radiotherapy and/or chemotherapy in man

Ph Libersa, M Laude


A prospective study of mandibular alveolar bone resorption has been achieved on 49 patients with upper aerodigestive tract tumor and treated by radiation therapy and/or a chemotherapy, on 30 patients who were not treated. All these patients were subjected to dental extractions followed by X rays in coronal and sagittal view, during at least one year, at the rate of one X ray every three months. The comparative study enabled to show a quite similar resorption for the two population, a slightly more important resorption on incisor and canin regions, and a stopping of the resorption about five months later according to dental extractions.

Radiation therapy and chemotherapy (therapeutic doses) may not have significant influence on alveolar bone resorption after dental extractions.
