A review of dental treatment of head and neck cancer patients, before, during and after radiotherapy: part 1

The incidence of head and neck cancer is on the rise. Most head and neck cancers are treated with surgery, radiotherapy, chemotherapy or a combination of these modalities. Patients undergoing radiotherapy can experience several unwanted oral side effects, which have both short and long term implications. Dental general practitioners should be aware of these implications and should liaise closely with the restorative consultants and the oncology team to establish the best oral care pathway. This two-part series is a review of the oral changes that occur during and after radiotherapy and the oral management of head and neck oncology before, during and after radiotherapy. This article deals with both immediate sequelae such as cellulitis, mucositis, dysphagia, dysguesia and weight loss as well as long term sequelae such as rampant caries, trismus, xerostomia and osteoradionecrosis. It also encompasses the importance and need for pre-radiotherapy assessment.
