Oral Health-Related Quality of Life in Chronic Liver Failure Patients Measured by OHIP-14 and GOHAI

Abstract

Background. Oro-dental diseases are prevalent in chronic liver failure (CLF) patients. The aim of this study was to evaluate the quality of life associated with oral health in candidates for liver transplant surgery. Materials and Methods. The demographic information of 105 end-stage liver cirrhotic patients was collected. All patients were ordered a panoramic view for pretransplant dental evaluation. The DMFT (decayed-missing-filled tooth) index was calculated for dental examination. The model for end-stage liver disease (MELD) was used for the severity of liver disease. The OHIP-14 (Oral Health Impact Profile) questionnaire and GOHAI (Geriatric Oral Health Assessment Index) questionnaire were applied to evaluate the impact of oral disease on the quality of life. Results. A total of 79 patients thoroughly completed the questionnaires; 79.7% were male, 32.9% were over 50, and 25.3% were less than 30 years old. Further, 12.7% smoked, 2.5% were illiterate, 64.6% had not finished school, and 10.1% had university degrees. Almost half of the cirrhotic patients were suffering from the disease for more than 3 years. Most complaints reported by the patients as "very often"were becoming self-conscious (13.9%) and being uncomfortable when eating any foods (13.9%) followed by feeling tense (12.8%). There was no significant difference between gender, smoking, age, and MELD score based on quality of life (OHIP and GOHAI) (P>0.05). The level of education (P=0.020), duration of disease (P=0.017), and DMFT index (P=0.039) had a significant impact on oral health-related quality of life in CLF patients. An inverse relationship was seen between the DMFT index and the quality of life. Conclusion. Oral health has a high impact on the quality of life of cirrhotic patients. The psychological dimension of oral health is the most debilitating factor affecting the quality of life. This shows the importance of professional oral care, oral health, and self-care education in this group of patients.
