Effect of Complete Denture Therapy on Oral Health-Related Quality of Life of Edentulous Patient

Edentulism is one of the most important oral health challenges, which results in adverse social and psychological consequences. A conventional complete denture is utmost usually used treatment modality for these patients. A few studies assessed the quality of life of patients before as well as one month after complete denture therapy. This study aimed to assess the consequence of complete denture therapy on oral health-related quality of life of edentulous patients. This study was conducted on 43 edentulous patients in 2018-2019 who met the inclusion criteria. After obtaining their written informed consent and ethical approval from the university’s medical ethics committee, patients were requested to fill out the standardized Persian version of the oral health impact profile-14 (OHIP-14) questionnaire before as well as one month after the delivery of complete denture via an interview. Data were analyzed using SPSS version 21 via the Wilcoxon and MannWhitney U tests. The total score of quality of life (OHIP-14) of patients considerably improved after treatment (P<0.001). The quality of life of patients significantly improved in all domains (P<0.001) except for functional limitation (P=0.122) and physical pain (P=0.009) domains, which had a more favourable status before the denture delivery. The difference in OHIP-14 total score of patients was significant regarding sex and age before (P=0.004 and P=0.006, respectively) and after (P=0.022 and P=0.007, respectively) denture delivery. Edentulous patients showed an improvement in oral health related quality of life at one month after denture delivery.
