Is there a relationship between general and oral health‐related quality of life in partially edentulous patients before and after implant treatment? A quasi‐experimental study

OBJECTIVE: The aim of this study was to determine the relationship between Oral Health Related Quality of Life (OHRQoL) and general health-related quality of life (GHRQoL) in partially edentulous patients before and after implant placement. MATERIAL AND METHODS: After obtaining informed consent, using convenient sampling method, 102 participants (64 female and 38 male participants with an age range of 18-81 years) were included in the study. Participants were required to fill EuroQol-5D (EQ-5D) and the Oral Health Impact Profile-14 (OHIP-14) questionnaire before implant surgery and three months after prosthetic placement. Data were not normally distributed, so non-parametric tests were used for data analysis. RESULTS: Data analysis was carried out on 93 participants. After implant treatment, Visual Analogue Scale (VAS) and EQ-5D score significantly increased by 0.05 and 0.06 units, respectively (p < .001 and p = .004, respectively). Also, the total OHIP-14 score significantly decreased from 15.89 to 6.18 after implant treatment (p < .001). CONCLUSION: Results indicated an increase in general and oral health-related quality of life after implant treatment. According to this study, there was a positive weak relationship between GHRQoL and OHRQoL before and after implant treatment.
