Is there an association between head and neck cancer diagnosis and self-reported dental fear? A dual-center cross-sectional study.

Abstract

Mental distress is highly reported in cancer patients, resulting in anxiety and depression most of the time. Both conditions, in turn, are recognized to be related to dental fear in adults; however, there are no studies on patients suffering from head and neck cancer. Thus, the present study aimed to investigate whether newly diagnosed patients with head and neck cancer are more prone to self-reported dental fear. This dual-center cross-sectional study was conducted with 25 healthy outpatients and 25 patients with a recent diagnosis of head and neck cancer, all requiring dental care. The patients were informed at the first appointment about their dental therapy planning and the Brazilian Portuguese Version of the Dental Fear Survey (DFS) questionnaire was then applied after appropriate instructions. The DFS total scores did not differ statistically between the groups (Mann-Whitney U test, P = 0,120) but the Cancer Group presented a slightly higher mean score (32.2 ± 10.0) than the Control Group (30.0 ± 14.2). Within the limitations of this study, newly diagnosed patients with head and neck cancer and healthy individuals seem to experience similar self-reported dental fear.
