This study aimed to assess oral health-related quality of life (OHRQoL) after long-term periodontal treatment in patients with chronic periodontitis (ChP) and compared it with the current clinical outcome and oral health status. Twenty years after therapy, 63 patients were re-examined. The dental and periodontal status and OHRQoL using the Oral Health Impact Profile-G49 (OHIP-G49) were assessed. Up to 75% of patients showed no probing depths >5 mm, bleeding on probing ≤25%, no pain and satisfactory function. A comparatively low perceived oral impact of ChP was represented by an OHIP-G49 score of 18.89 ± 21.66. The most common reported impairment was physical pain. Correlation between oral quality standard and the OHIP-G49 was limited to the physical pain subdomain.
