Abstract
This study compared the self-assessed health-related quality of life (HRQoL) and degree of depression between patients with chronic neuropathic nonodontogenic orofacial pain (NOFP) and healthy controls using the Short Form Survey (SF-36) health status questionnaire and Beck Depression Inventory II (BDI-II). This controlled cross-sectional study included 100 patients and 119 healthy controls. The diagnostic protocol recorded the following: 1) pain intensity using a visual analog scale for the time of examination and during the one-month prior; 2) evidence for neuropathic pain using the Leeds questionnaire for neuropathic signs and symptoms (LANSS); 3) emotional status using the BDI-II; and 4) HRQoL using the SF-36 questionnaire. The mean LANSS score was 17.18 in the patient group and 0.0 in the control group. The mean BDI-II score was 18.31 in the patient group and 5.87 in the control group. The SF-36 scores were shown with Mann-Whitney U testing to have statistically significant differences between the patient and healthy control groups in all categories. Vitality was the only SF-36 category in which the patient group scored higher than the control group. In conclusion, NOFP significantly reduces the self-reported HRQoL. NOFP is also related to the development of depression, but does not affect its severity. There is a significant correlation between depression and low quality of life in patients with NOFP.
