Study the risk of complications after dental extractions in patients recieving radiotherapy.
Dental extractions before radiotherapy in the head and neck region is an established part of the treatment plan for patients with malignant disease. There are contradictory results in the literature regarding the importance timing and magnitude of extractions. It is important to minimize complications in this patient group since the regular therapy is already detrimental to the affected tissues. Patients were extracted from the ARTSCAN register were the population was followed for 4 years for several factors, including development of osteoradionecrosis. The aim is to evaluate which diagnoses are more prone to develop complications after extraction. If there is a relationship between occurrence of complication and magnitude of dental pathology.
