Characterization of JAK1 and JAK2 Activation in Gingival Tissues During Homeostasis and Periodontitis

The goal of this observational study is to examine JAK1/2 pathway activation in gingival tissues from adults with healthy gingiva and those with inflamed gingiva (periodontitis). The main question it aims to answer is:

Is the JAK1/2 pathway overactivated in periodontitis compared to health?

A secondary outcome will be to describe the histological areas, such as epithelium or lamina propria, where the JAK1/2 pathway will be activated including the different subpopulation of cells.

The protocol include one visit where the gingival biopsies are taken.

Participants with healthy gingiva and periodontitis will donate gingival tissue to study the JAK1/2 pathway. All participants will receive diagnosis and treatment of the gingival condition.
