Abstract:
Pyogenic granuloma (PG) is an inflammatory hyperplastic lesion of the oral cavity. The most common etiological factors for PG are low-grade local irritation, traumatic injury, or hormonal factors. Clinically, it appears to be smooth or lobulated exophytic lesion. It appears to be erythematous papule and is either pedunculated or has a sessile base. The lesion has shown a recurrence rate of 15.8%. Various treatment modalities have been present in the literature. The present article emphasized the treatment modalities and an effort to treat the recurrence of PG with the use of platelet-rich fibrin (PRF) membrane. This case report presents a 28-year-old female patient who had reported with PG that recurred twice in 2-year period. The lesion appeared to be recurrent with sessile base and was diagnosed clinically and histopathologically as PG. The PG was excised with the conventional scalpel method exposing the underlying bone. The exposed surface was then covered with PRF membrane. At 12-month follow-up period, the patient did not show any further recurrence of the lesion.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
