Özet

BN has important roles in several physiological events, including bone growth and immune system. New infection-free cranioplasty and has an osteogenic activities material that are compatible with tissue are being developed. We aimed in our study to examine whether different combinations of Boron-nitride/Hydroxyapatite are embedded into the scaffold in the treatment of calvarial defects. 200 adult female Sprague-Dawley rats divided into 10 equal groups. Osteotomy was made by trepan drill in 8 mm diameter. The scaffolds were placed in the rats and were left to recovery for 2 months. During the experiment, CT scans were taken from the calvarial areas of the rats in the 2nd, 4th and 8th weeks. Significant healing was observed in defect diameters in 2.5% BN + 10% HA, 2.5% BN and 5% BN + 10% HA, respectively. After 8 weeks, it was seen that the amounts of OPN, BMP-2, RunX2 and ALP mRNA expression significantly decreased in 2.5% BN + 10% HA, 2.5% BN, 5% BN + 10% HA and 5% BN groups. It was shown that bone recovery was at the best grade in the groups, which contained 2.5% BN and 2.5% BN + 10% HA when compared to the other groups. BN is a very promising agent that will be used in reconstructive surgery for the treatment of calvarial bone defects.
