Oral health‐related quality of life and standard of treatment in aggressive periodontitis patients more than 5 years after therapy.

Objectives: To assess OHRQoL in patients with aggressive periodontitis (AgP) after periodontal treatment using the Oral Health Impact Profile‐49 (OHIP‐49) and compare to patients' dental status. Material and methods: More than 5 years after therapy, 71 patients were examined and answered the OHIP‐questionnaire. The dental and periodontal status were assessed according to the SSO (Swiss Dental Society) criteria. Descriptive statistics were performed with SPSS, correlation analysis and tests for differences using R 3.2.2. Results: More than 90% of all patients showed no probing depths (PD) >5 mm, a bleeding on probing (BOP) index below 35%, and a sufficient function. Four patients showed no visible plaque, PDs ≤ 3 mm, a BOP below 10%, and an optimum function. Non‐smoking and compliant patients exhibited a more favourable status. The OHIP‐49 added up to 24.9 points, representing a comparatively high satisfaction of AgP‐patients with their oral status. The subscale which most patients reported impairment in was "functional limitation." A correlation between quality standard and the OHIP‐49G could only be shown in the psychological disability subscale. Conclusion: After treatment, a moderate to high quality level can be retained over more than 5 years. Most patients are satisfied with their oral health. Correlations between the objective and subjective view could not be found, apart from the subscale "psychological disability." [ABSTRACT FROM AUTHOR]
