In this study, the quality of life of patients with stage 3 grade C periodontitis who underwent surgical and non-surgical periodontal treatments was evaluated. Patients were compared based on their quality of life using OHIP-14 and OHRQoL-UK questionnaires, as well as a VAS scale, against those who did not receive periodontal treatment, those who received only phase 1 treatment one month prior, and those who underwent periodontal surgical treatment three months prior.

Currently, the most commonly used reliable scales to measure oral health-related quality of life are the OHIP-14 (Oral Health Impact Profile) and OHRQoL-UK questionnaires. Fifty patients with stage 3 and grade c whose clinical periodontal records (PI, GI, PD and BOP) were obtained were included in the study. OHRQoL-UK, OHIP-14 questionnaires and VAS were applied at the first session (T1). Initial periodontal treatment (scaling, polishing and oral hygiene education) was performed, and non-surgical periodontal treatment (root surface debridement under local anesthesia) was performed in the next session. Three to four weeks after this treatment, patients were recalled for follow-up and all clinical indices and questionnaires were repeated (T2). After re-evaluation, the patients were divided into a surgical group (23 patients) and a non-surgical group (27 patients). Open flap debridement was performed in areas requiring surgery (radiologic bone loss and SCD>5mm). Patients were recalled 12-14 weeks after surgery and all indices and questionnaires were repeated (T3).
