RESUMO
OBJECTIVE: To assess in a cross-sectional study the impact of including dental professionals in the multidisciplinary treatment team of head and neck squamous cell carcinoma (HNSCC) patients on the long-term oral health status. MATERIALS AND METHODS: Oral health status, dental care behaviours, and oral health-related quality of life were assessed based on a clinical and radiographic examination, interview, and medical records in patients treated for HNSCC ≥ 6 months ago. This patient group ('cohort 2') was treated in a multidisciplinary treatment team including dental professionals and compared to a group of HNSCC patients previously treated at the same university, but without dental professionals included in the multidisciplinary treatment team ('cohort 1'). RESULTS: Cohort 2 consisted of 34 patients, who had received a dental check-up and if necessary, treatment by dental professionals prior to the initiation of cancer treatment. This cohort showed significantly improved oral hygiene habits and a better periodontal health status compared to cohort 1. However, cohort 2 still presented high demand for treatment due to active carious lesions; only a few, statistically insignificant improvements were detected compared to cohort 1. CONCLUSION: Including dental professionals in the multidisciplinary treatment team of HNSCC patients has a positive impact on patient oral health status-primarily in terms of periodontal disease-6 months and longer after finishing cancer therapy. CLINICAL RELEVANCE: A team-based approach including dental professionals specialised in head and neck cancer improves oral health status.
