Supernumerary teeth are an odontogenic anomaly, involving an increase in the number of teeth compared to the normal amount. Platelet-Rich Fibrin (L-PRF) is a matrix rich in platelets and white blood cells that promotes tissue healing and regeneration. The Extraction of a supernumerary lower third premolar followed by placement of L-PRF membrane. A 27-year-old male patient with a probable lingual supernumerary premolar. Surgery was scheduled, including L-PRF. Blood was extracted to prepare the L-PRF membrane, followed by anesthesia, linear incision, mucoperiosteal detachment, osteotomy, extraction, treatment of the surgical site with L-PRF membrane placement, and interdental suturing. Antibiotic, anti-inflammatory, and analgesic medication was prescribed. The L-PRF technique is simple and cost-effective. Postoperative results were favorable, with good healing, absence of pain, swelling, or infection was observed.

Keywords : Supernumerary tooth; leukocyte-platelet-rich fibrin; tissue regeneration.
