The as-deposited films were found by x-ray diffraction to be amorphous but magnetic, and showed large high field susceptibility. The films were studied after they were annealed at various temperatures up to 850°C. It was observed that the films crystallize upon annealing and the value of the saturation magnetization increases with annealing temperature. The high field susceptibility, on the other hand, decreases with increasing anneal temperature. The measured ferromagnetic resonance spectra of these films indicated that the films consist of at least two different magnetic materials. A significant portion in the film crystallizes and the value of saturation magnetization of this portion tends to the bulk value as annealing temperature is increased. However, a small portion of the film remains in a highly defective state all through, even up to annealing temperatures of 850°C. The high field susceptibility data indicates that point defects could play an important role in determining the magnetic properties of these films.

The main objective of this article is to evaluate the efficacy of platelet-rich fibrin (PRF) for secondary alveolar bone grafting. Patients between 9 and 14 years of age were included in study and were divided in two groups: Group 1—iliac bone with PRF and group 2—iliac bone without PRF. Radiographic assessment was done preoperatively, immediate postoperatively, and at 3, 6, and 9 months, respectively. Vertical bone height was assessed using 4-point scale. In group 1, 14 patients showed grade 1 resorption at 3 months and at 6 and 9 months all patients showed grade 1 resorption. In group 2, 16 patients had grade 1 resorption at 3 months, 2 patients had grade 2 resorption at 6 months, and 6 patients had grade 2 resorption at 9 months. Use of PRF growth factor with autogenous bone results in greater osteogenic effect which increases new bone regeneration and better wound healing.
