RESUMO
INTRODUCTION: Despite much research on the impact of edentulism and prosthetic rehabilitation on food and nutrient intake, there is little information on how replacing complete dentures affects social and emotional issues around eating. OBJECTIVES: To investigate, in a cohort study, how replacing conventional complete dentures affects eating-related quality of life (ERQoL). A secondary aim was to test the responsiveness of an Emotional and Social Issues Related to Eating (ESIRE) questionnaire to change in ERQoL. METHODS: Participants, recruited from the Dental Hospital, Newcastle-upon-Tyne, UK, completed the self-administrated ESIRE questionnaire before and after provision of new conventional complete dentures. Paired t test was used to determine any change between pre- and posttreatment ESIRE scores, which can range from 0 (poor) to 100 (excellent). Cohen's d effect size was used to measure the magnitude of change in ERQoL. Standardized response mean (SRM) was used to measure the responsiveness of the ESIRE questionnaire to changes in ERQoL. RESULTS: Fifty-five participants aged 52 to 85 y (mean, 72 y), including 21 males (42%) and 29 females (58%), completed the study. A statistically significant improvement in the total ESIRE scores was found, mean (SE) +20.3 (3.30), P < 0.001. Equally, all domains of the ESIRE questionnaire showed significant improvements: enjoyment of food/eating, +27.3 (3.63), P < 0.001; self-consciousness/embarrassment, +18.1 (3.88), P < 0.001; interruption to meals, +13.3 (5.27), P < 0.05; confidence when eating, +18.7 (4.84), P < 0.001; time for eating/preparation of meals, +18.5 (4.85), P < 0.001); and functional ability to eat, +18.2 (3.67), P < 0.001). Cohen's d was large (0.95) for the total score and ranged from medium (0.37) to large (1.30) for all domains. Value of SRM was large (0.87) for the total score and ranged from medium (0.36) to large (1.1) for all domains. CONCLUSION: Denture replacement can directly improve ERQoL. The ESIRE questionnaire was responsive to clinically important changes in ERQoL. KNOWLEDGE TRANSFER STATEMENT: The results of this study improve the understanding of the impact of denture replacement on eating-related quality of life (ERQoL). Clinicians are encouraged to pay more attention to the impact of wearing conventional complete dentures on social and emotional issues around eating. The findings should motivate clinicians and inspire specialists in prosthodontics and oral rehabilitation to continue providing conventional complete dentures as a suitable treatment option for edentulous patients.
