Abstract

Objective: This study aims to describe the status and certain factors related to oral hygiene in patients after radiotherapy for head and neck cancer at Vietnam National Cancer Hospital from 2023 to 2024. Subjects and Methods: A cross-sectional descriptive study was conducted on 156 patients aged 18 and older who had undergone radiotherapy for head and neck cancer from February 2023 to September 2024. Patients were examined and assessed for oral hygiene status using the OHI-S index after 1 month, 2 months, 3 months, and more than 3 months of radiotherapy. Results: The percentage of patients with a poor OHI-S index increased with age: 25.0% in the 18-34 age group, 50.5% in the 35-59 age group, and 56.9% in the 60+ age group. However, the percentage of patients with a good OHI-S index gradually increased over time after radiotherapy. Patients aged 60 and older were 5.5 times more likely to have a moderate-to-poor OHI-S index compared to the 18-34 age group. Female patients had a moderate-to-poor OHI-S index 0.08 times that of male patients. Patients with oropharyngeal and hypopharyngeal cancer had a moderate-to-poor OHI-S index 3.72 and 3.61 times higher, respectively, than those with nasopharyngeal cancer. Conclusion: Among head and neck cancer patients, the percentage of individuals with a poor OHI-S index increased with age, but the overall OHI-S index showed improvement over time following radiotherapy. Factors associated with oral hygiene status included age (60+ years), female gender, radiotherapy location (oropharyngeal and hypopharyngeal cancer), as well as education level and occupation.
