Effect of Smoking Cessation on Salivary IL-1β and PGE-2 Levels Following Non-Surgical Periodontal Therapy

Not Applicable

Completed

• Conditions: Periodontal Diseases; Smoking Cessation

• Registration Number: NCT06145685
• Lead Sponsor: October 6 University

Brief Summary

The aim of this study is to evaluate the effect of smoking cessation on inflammatory markers following non-surgical treatment of periodontal disease. This is to assess the period of smoking abstinence needed before any periodontal surgery in order to reverse the negative effects of the reported increased levels of inflammatory markers (IL-1β and PGE2 in this study) associated with smoking on the healing and the periodontium.
