“…RT for HNC typically involves total doses of 6,000–7,000 cGy, delivered in daily fractions over 6–7 weeks (Pfister et al., ), and is known to cause a number of oral complications. These include oral mucositis, oral pain, hyposalivation, increased risk of dental caries, reduced mouth opening, and osteoradionecrosis (Buglione, Cavagnini, Di Rosario, Maddalo, et al., ; Buglione, Cavagnini, Di Rosario, Sottocornola, et al., ). Much of the data on oral complications of RT for HNC come from smaller single‐center studies using older RT techniques.…”
