Platelet Rich Fibrin and Nanocry stalline Hydroxyapatite with Collagen Combination in Treatment of Periapical Lesion: A Novel Clinical Approach.

ABSTRACT

Aims: To use platelet rich fibrin (PRF), which is an autologous platelet concentrate, along with nanocrystalline hydroxyapatite with collagen for treatment of periapical lesion and negotiation of calcified canal of adjacent tooth. Case Presentation A 19-year-old female reported to the Department of Conservative Dentistry and Endodontics with chief complaint of pain in maxillary right central incisor. Past dental history revealed trauma which she sustained 10 yrs back in the same region. On intraoral examination, there was a draining sinus, in relation to the apex of 11. Also discolouration and crown fracture was found in relation to 11. Periapical radiograph revealed a large diffused periapical radiolucency in relation to 11 and 12, open apex of 11 and calcified root canal in relation to 12. Technique Used in the Study A periapical surgery under local anaesthesia was planned in the region of maxillary right anterior region in relation to tooth no 11 and 12. Before surgery calcified canal of tooth no 12 was negotiated. PRF and nanocrystalline hydroxyapatite with collagen combination were placed in bony cavity. Follow up of the case was done for period of 6 months. Discussion: In present case combination of nanocrystalline hydroxyapatite with collagen and PRF is used, as it helps in faster bone regeneration. Graft material is osteoconductive and collagen network provides a better scaffold for clot formation and bone regeneration. Conclusion: The combination of PRF and nanocrystalline hydroxyapatite with collagen has been demonstrated to be an effective approach to induce faster periapical healing in present case with large periapical lesion.
