Abstract Purpose Several studies have found associations between periodontitis and various types of cancer. Since the site of head and neck cancer (HNC) has contiguity or proximity to the oral cavity, it may be particularly influenced by oral inflammation. This study aimed to determine whether HNC patients have poor oral health as compared to those with other types of cancer. Methods This study retrospectively examined oral environmental factors including periodontal inflamed surface area (PISA), a new periodontal inflammatory parameter. A total of 1030 cancer patients were divided into the HNC (n = 142) and other cancer (n = 888) groups. Furthermore, the HNC group was divided into high (n = 71) and low (n = 71) PISA subgroups, and independent risk factors affecting a high PISA value were investigated. Results Multivariate logistic regression analysis showed that number of missing teeth (odds ratio 1.72, 95% CI 1.15–2.56, P < 0.01), PISA (odds ratio 1.06, 95% CI 1.03–1.06, P < 0.05), and oral bacterial count (odds ratio 1.02, 95% CI 1.01–1.03, P < 0.01) were independent factors related to HNC. In addition, multivariate logistic regression analysis indicated that current smoker (odds ratio 7.51, 95% CI 1.63–34.71, P < 0.01) and presence of untreated dental caries (odds ratio 3.33, 95% CI 1.23–9.00, P < 0.05) were independent risk factors affecting high PISA values in HNC patients. Conclusion HNC patients have higher levels of gingival inflammation and poor oral health as compared to patients with other types of cancer, indicating that prompt oral assessment and an effective oral hygiene management plan are needed at the time of HNC diagnosis.
