Introduction: There is an increasing recognition that oral disorders might cause significant impact on life of patients. To date, there has been less focus on oral health-related quality of life (OHR-QoL) measures in outpatient clinics for oral diseases.
Aim: This study was carried out to test the assumption that patients with common tongue conditions would report a worse OHR-QoL than controls.
Method: A total of 59 oral subjects with various tongue conditions and 44 controls were enrolled in this prospective study. Demographic, clinic, and laboratory findings of oral subjects were recorded, and an OHR-QoL questionnaire, named 14-item oral health impact profile (OHIP-14), was completed by oral subjects and controls at the outpatient clinics of four centers.
Results: Median of OHIP-14 total scores of the oral subjects with common tongue conditions was 11 and that of controls was 4 (P = 0.00) indicating that OHR-QoL was worse in oral subjects than in controls. Most (n = 39, 66%) of the oral subjects had mild to distressing pain. Eating was the most commonly affected function. Oral subjects were arbitrarily divided into two groups. Group 1 (n = 22) included patients with tongue conditions which were associated with candidal infections and the other patients formed Group 2 (n = 34). A significant difference between Group 1 and Group 2 was observed only with respect to functional limitation (P = 0.027), indicating that oral subjects of Group 1 had more functional limitation.
Conclusion: Common tongue disorders were believed to be innocuous by most. When the influence of one of the most common form of oral disease (tongue conditions) on OHR-QoL was taken into consideration, OHR-QoL will provide an additional dimension and may help to improve the impact of a disease on an individual's life. Moreover, we also encourage more extensive use of these OHR-QoL instruments for oral diseases at outpatient clinics.
