This scoping review aimed to map the literature on oral hygiene protocols and fluoride use in patients undergoing radiotherapy.
An ample search was performed in ten databases, including part of the “gray literature”. Clinical trials and observational studies that used radiotherapy in the head and neck region and evaluated the occurrence of radiation-related caries were included.
twenty-one studies were included in the review. The studies generally presented different methods of oral care and fluoride use. Several studies have shown good results for oral care instructions in preventing radiation-related caries. The main strategies found in the articles were oral hygiene instructions, professional teeth cleaning, recommendation for the use of fluoride toothpaste, and monthly follow-up. Fluoride gel was the most commonly used fluoride gel product (72%). Its main recommendation for use was at least 5 min at night daily. Most of these studies (60%) used custom-made trays. Other fluorides methods applied were fluoride varnish, fluoride month rinses, and high-fluoride containing toothpaste.
Oral care, such as hygiene instructions with regular dental follow-up and daily fluoride, seem to be good strategies for preventing radiation-related caries. Periodically monitoring these patients is one of the most important strategies.
