Evaluation of the Changes in Matrix Metalloproteinase-9 Levels With Salvadora Persica (Miswak) in Periodontal Fibroblasts and Gingival Crevicular Fluid in Patients With Periodontitis

Despite the clinical benefits mentioned, miswak use have been associated with some drawbacks such as clinical attachment loss; improper use of miswak over a long period can result in a risk of oral tissues injury. To date, there is a lack of comprehensive evidence-based literature to guide a safe and effective accepted practice that can subsequently be used as oral hygiene instructions for miswak users. Correlation between the in vitro and in vivo findings will be performed to evaluate the translational relationship between the effects of miswak on periodontal fibroblast inflammatory activity and the corresponding clinical and biomarker outcomes in patients with periodontitis. Matrix metalloproteinase-9 (MMP-9) and prostaglandin E2 (PGE2) levels obtained from periodontal fibroblast cultures will be compared with gingival crevicular fluid (GCF) MMP-9 and PGE2 levels and clinical periodontal parameters, including probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI).
