Impact of Nonsurgical Periodontal Therapy for Stage 2 and 3 Periodontitis on Oral Health Related Quality of Life: A Clinical Trial

Periodontitis is a chronic disease characterized by progressive loss of tooth-supporting tissues. It is adversely affecting function, esthetic, and general wellbeing. Oral health related quality of life (OHRQoL) is the part of quality of life which is affected by oral cavity-related status. Majority of clinical studies emphasize on periodontal outcomes after periodontal therapy. However, tangible outcomes perceived by the patient such as need for re-treatment, tooth survival, and OHRQoL are mostly neglected. OHRQoL is mainly measured by using self-reported questionnaires and the most commonly used one is Oral Health Impact Profile (OHIP).

Nonsurgical periodontal therapy (NSPT) is the gold-standard technique for treating shallow to moderately deep periodontal pockets. The principle of this technique is based on mechanically disrupting subgingival dysbiotic biofilm, consequently; restoring homeostasis and healthy state of periodontal tissues. Indeed, halting progressive periodontitis is a major contributor for improving oral health and increasing tooth survival rate which are positively perceived by the patients. Previous studies consistently reporting improvement of OHRQoL following periodontal treatment. Therefore, this study aimed to investigate the impact of NSPT on OHRQoL for Stage (S)2 and S3 periodontitis patient and the factors predicting the outcomes.
