Oral health–related quality of life improvement following full-mouth implant rehabilitation in stage III/IV periodontitis patients

Aims: Periodontitis is a chronic inflammatory condition that significantly impairs oral function and quality of life. In advanced stages (stage III/IV), full-mouth extraction followed by implant-supported prosthetic rehabilitation is often necessary, yet limited data are available regarding the effect of this transition on oral health–related quality of life (OHRQoL). To assess the changes in OHRQoL among patients with stage III/IV periodontitis who underwent complete tooth extraction and full-arch implant-supported prosthetic rehabilitation, and to evaluate the impact of clinical and demographic variables on patient-reported outcomes.Methods: In this longitudinal study, 54 patients diagnosed with stage III/IV periodontitis were enrolled. Clinical parameters and OHRQoL were assessed using the Turkish version of the Oral Health Impact Profile-14 (OHIP-14). Measurements were recorded at two time points: at baseline (T0), when patients retained their natural dentition and clinical assessments were obtained from periodontal tissues, and at follow-up (T1), two years after completion of full-mouth implant-supported rehabilitation, when clinical assessments were performed on peri-implant tissues. Statistical analysis involved paired t-tests and multiple linear regression to evaluate changes and influencing factors. Results: A significant improvement in OHIP-14 scores was observed, decreasing from 44.96±11.63 at baseline to 16.81±8.61 after treatment (p
