Impact of complete dentures treatment on Oral health-related quality of Life (OHRQoL) in edentulous patients: A descriptive case series study.

Abstract

Objectives: To evaluate the changes in oral health-related quality of life [OHRQoL] before and three months after complete denture oral rehabilitation using the Geriatric oral health assessment index [GOHAI] in Pakistani elderly edentulous patients.

Methods: In this descriptive case series study a total of 80 edentulous patients were recruited from Islamic International Dental Hospital, Islamabad, Pakistan from November 2021 to April 2022. The OHRQoL was evaluated twice by using the GOHAI- Urdu version. First, before getting the complete denture, and subsequently after three months of using a prosthesis. The data were analysed using SPSS-23. Pre and post-comparison were done by t-test. Moreover, the ANOVA test was utilized to assess the socio-demographic variables-GOHAI score and association.

Results: The mean GOHAI scores increased significantly from 22.9 (SD = 3.01) at baseline to 28.1 (SD = 5.59) after three months (P = 0.001), reflecting an overall increase of 5.2 points. At baseline, the ability of the patient to swallow comfortably was found to have the highest mean GOHAI score of 3.02 (SD= 1.24) and after three months of complete denture insertion, the same questionnaire item further improved with the highest mean GOHAI score of 3.43 (SD=1.05). The socio-demographic characteristics-based comparison of mean pre and post-insertion GOHAI scores suggested a statistically significant difference (p=0.001).

Conclusion: The OHRQoL in elderly edentulous patients improved after complete denture delivery, and a significant improvement was noted in most GOHAI domains.
