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 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.
