This study determines the effect of an integrated 12-month follow-up support programme on the oral health of patients with head and neck cancer (HNC) who received radiotherapy (RT). Participants were randomly assigned to an intervention group (n = 47) or a control group (n = 45). The intervention group received usual care and an integrated supportive programme, which included face-to-face education and telephone coaching. The control group received usual care. After a clinical dental examination, the prevalence of caries, gingival inflammation and plaque were registered. Oral health impact profile (OHIP)-14 and the WHO Oral Health Questionnaire for Adults were used to evaluate oral health in both groups. A total of 79 participants completed a 12-month follow-up. The intervention group had lower caries increment between baseline and the 12-month follow-up compared with controls, although this was not statistically significant. After 12 months, the intervention group had statistically significant better outcomes in the plaque index (p = 0.038) and the OHIP-14 (p = 0.002) than the control group. No statistically significant differences were found between the two groups concerning gingival index. However, the intervention group reported an overall better state of teeth (p = 0.034) and gums after 12 months (p = 0.042). The integrated supportive programme showed positive effects on improving oral health in patients with HNC regarding plaque control, the state of teeth and gums and oral health-related quality of life during the 12-month follow-up.
