Clinical dental management of the head and neck irradiated patient: topics of interest for clinicians

ABSTRACT

To discuss important topics regarding the dental procedures performed in patients before, during and after the radiotherapy treatment. The biological effects of ionizing radiation on bone tissue focusing on clinical care will be described. The invasive and not invasive procedures after radiotherapy treatment in the head and neck region will be addressed using scientific evidences to determine the appropriate moment for tooth extractions, periodontal management, and preventive procedures for osteoradionecrosis. Methods: Thirty-three studies including original studies and reviews were selected in MEDLINE database (PubMed). No year of publication restriction was applied. Language was restricted to the English, and the following Medical Subject Heading terms were used: radiotherapy, osteoradionecrosis, dental management. Studies of osteoradionecrosis involving clinical management of irradiated patients, with an emphasis on updated guidelines and protocols were selected. Results: Care in dental procedures were related about restorative treatment, endodontic treatment, rehabilitation for edentulous regions using prostheses and implants and periodontal procedures before, during and after RTX treatment. Conclusions: The dental procedures should and can be performed before, during but also after radiotherapy. However, the clinical procedures should be less invasive as possible. A maintenance plan that reduces the necessity for major and more invasive treatments after radiotherapy is recommended
