Gingival overgrowth (GO) is a pathology with important aesthetic and functional implications and with a multifactorial pathogenesis. Incriminated etiological factors include antihypertensive, antiepileptic and immunosuppressant medication. We aimed to evaluate the induction of gingival overgrowth on experimental rats, depending on the drug type, dose and duration. In the research conducted by us, the increase in gingival tissue production occurred gradually, depending on the administered medication and the time elapsed after its start. The study conducted shows that experimentally induced gingival overgrowth of the administered drugs is made possible by altering tissue homeostasis through altering the fibrocyte cell populations involved in the tissular turnover as well as those involved in the inflammatory process. A better understanding of the pathogenesis of this undesirable effect may lead to the development of improved management strategies for preventing it, or reducing it through non-surgical methods.
