Treating with Platelet Rich Fibrin After Wisdom Teeth Removal

An interesting article titled “Evaluation of Treatment Outcome After Impacted Mandibular Third Molar Surgery With the Use of Autologous Platelet-Rich Fibrin: A Randomized Controlled Clinical Study,” appears in the Journal of Oral and Maxilofacial Surgery written by Nilima Kumar and et al. (vol 73, pp. 1042-1049). The article sets out to explore the effect of platelet-rich fibrin (PRF) on postoperative pain, swelling, trismus, periodontal healing near the second molar, and progress of bone regeneration in upper wisdom teeth extraction sockets.
