Abstract
Introduction Head and neck cancer (HNC) patients should receive a dental assessment at an appropriate time before commencing radiotherapy (RT), to prevent complications such as osteoradionecrosis (ORN) if extractions are required. A recent orthopantomogram radiograph (OPG) is part of this assessment.Aim To compare the delivery of pre-RT dental assessment at the Regional Oncology Centre against national guidelines in regard to OPG assessments and timing of extractions.Materials and methods A consecutive cohort of patients treated curatively were selected within two timeframes (January to March 2018 and January to March 2019) using multidisciplinary team records at Liverpool University Hospital. Patient notes, x-ray images and records were examined.Results In total, 145 patients were identified. Eighty-nine percent (129) had an OPG radiograph and 72% (104) had a pre-RT dental assessment. Oral and laryngeal sites had the highest number of missed assessments. Altogether, 54 patients had dental treatment, with 47 undergoing extractions. Extractions were completed a median 13 days before RT started. By November 2020, no patients had been diagnosed with ORN.Conclusions Three-quarters of patients received a pre-RT assessment but there is scope for improvement. OPGs should be part of initial HNC staging and referral to Regional Oncology Centre dental services should be made as part of the pre-RT workup.
