guidelines exist for preventive dental care before radiation therapy (RT) in
patients with head and neck cancer (HNC). An ongoing multicenter, prospective
cohort study, Clinical Registry of Dental Outcomes in Head and Neck Cancer
Patients (OraRad), is addressing this knowledge gap. The authors evaluated the
level of dental disease before RT in the OraRad cohort, factors associated with
dental disease, and dental treatment recommendations made before RT. As part of
OraRad, the authors assessed caries, periodontal disease, dental
recommendations, and dental interventions performed before RT.
Key Words. Radiation therapy; dentistry; caries; periodontal diseases; head
