The Quality of Life Associated with Oral Health in Patients Treated with Removable Denture in Prosthodontics Department of School of Dentistry in Sari, Iran, During 2019-2020

Reconstruction of teeth using partial or complete dentures is the only treatment for most edentulous patients. The duration of edentulism and the use of complete dentures can affect the patient’s quality of life. Therefore, this study aimed to evaluate the quality of life associated with oral health in patients referring to the Prosthodontics Department, School of Dentistry, Sari, Iran. In total, 235 patients treated in the Prosthodontics Department, School of Dentistry, Sari, Iran were selected and studied in this descriptive-analytical cross-sectional study. The required information was collected using the Oral Health Impact Profile-14 questionnaire (OHIP-14). Data were analyzed through SPSS22 and using descriptive and analytical tests, such as Mann-Whitney, t test, one-way analysis of variance, and multivariate regression. In total, 103 men (43.8%) and 132 women (56.2%) with mean age of 58 ± 10.3 years participated in this study. The duration of denture use was between 3 and 108 months. The mean score of patients’ quality of life had a statistically significant relationship with the type of treated jaw, the type of removable prosthesis, and the duration of prosthesis use (P < 0.05). However, no statistically significant relationship was observed between the mean score of quality of life with age and gender (P > 0.05). Based on the obtained results, the quality of life was higher among those who used dentures for a longer period of time and also in patients with complete dentures. However, the quality of life was lower in people who used mandibular dentures, compared to other groups.
