ABSTRACT:Background and objectives: Preservation of bone after extraction is of prime importance. Good and sound bone present is useful for further prosthodontic rehabilitation or implant placement. Various bone grafts are available for restoring the continuity of bone which are either autogenic or allogenic. PRF being autogenous and drawn from individual’s blood serves as a good substitute for bone reconstruction. The aim of this study is to assess the effects of PRF in extraction socket healing after tooth extraction. Materials and methods: Thirty patients of age group between 15-55 years visiting the dept of oral and maxillofacial surgery needing single tooth simple extractions were included in the study. PRF was prepared with blood drawn from individuals using standard technique. PRF was placed in extraction sockets followed by pressure application and suturing was done. Radiographic assessment of socket was done using IOPA. Ridge width was assessed using cast. The clinical follow up assessments were performed at 1, 4 and 12 weeks. Results: 18 males and 12 females were included in the study mean age of the patients was 35.43 years. The alveolar width for sockets were 11.33 ± 3.43 mm, 10.85 ± 3.23 mm and 10.45 ± 3.32 mm at 1, 4 and 12 weeks with loss in alveolar bone height being 0.4 ± 0.13 mm, 0.7 ± 0.17 mm and 0.8 ± 0.12 mm at 1, 4 and 12 weeks. The bone fill was measured by mean of gray level histogram values of IOPA of the extraction sockets obtained through Adobe Photoshop 7.0 software. It was 68.66 ± 2.36%, 80.34 ± 3.18% and 93.23 ± 2.07% at 1, 4 and 12 weeks respectively. Conclusion: Platelet-rich fibrin (PRF) placement after extraction procedure improves the bone width and bone height and quality of bone. The good amount of bone serves as an important precursor for future implant placement or prosthodontic rehabilitation of tooth.
