The objective of this in vivo experiment is to assess the modulatory impact of carvacrol (found in plants such as Origanum vulgare) and magnolol (isolated from the bark of Magnolia officinalis) on two key gingival biomarkers, IL-6 and TNF-α, which are central to mediating inflammation in periodontal disease coupled with diabetes mellitus. This evidence concerns the gene TNF and periodontal disorder.
