Abstract
ABSTRACT
Background
Stage III, Grade B periodontitis compromises periodontal support, masticatory function, and oral health‐related quality of life (OHRQoL). Its functional and patient‐reported recovery across sequential periodontal treatment phases remains underexplored.
Objectives
This study evaluated the effects of comprehensive periodontal therapy on clinical parameters, masticatory performance, and OHRQoL.
Methods
Twenty systemically healthy patients with Stage III, Grade B periodontitis and 20 periodontally healthy controls were included in this prospective clinical study. Clinical periodontal parameters, tooth mobility (Periotest), masticatory performance (silicone cube chewing test with sieve analysis), and OHRQoL (OHIP‐14) were assessed. Periodontitis patients were evaluated at baseline, after non‐surgical therapy, and following surgical treatment. Comparisons with healthy controls used one‐way ANOVA, while longitudinal treatment effects were analysed using repeated‐measures ANOVA with Geisser–Greenhouse correction and Šídák's multiple‐comparisons test. Spearman correlation assessed associations between masticatory performance and OHRQoL.
Results
Patients with periodontitis exhibited significantly worse baseline clinical parameters, masticatory performance, and OHRQoL than controls (

Conclusion
Comprehensive periodontal therapy improves periodontal status, masticatory performance, and OHRQoL in Stage III, Grade B periodontitis. Parallel improvements in objective function and patient‐reported outcomes demonstrate the multidimensional benefits of periodontal rehabilitation.
