Histologic Evaluation of the Effect of Mecsina Hemostopper on Bone Regeneration for Critical-Size Defects
Özet
Purpose: Acceleration of the bone healing period and/or increasing the quality of newly formed bone still have great importance in the field of oral and maxillofacial surgery. The aim of this study was to evaluate the effect of isolated liquid Mecsina (herbal extract) and its combination with xenogeneic graft material (bovine bone graft) on bone regeneration. Materials and Methods: Full-thickness critical-size defects with 10-mm diameter and 2-mm depth were created on the calvarial bone region in 28 Sprague Dawley male rats. Four groups were generated: Mecsina Hemostopper, Mecsina Hemostopper + graft group, only graft group, and empty control group. On the 28th day following surgery, all animals were sacrificed. The calvarial samples were evaluated both histopathologically and histomorphometrically. Results: According to the histopathologic evaluation result, vascular proliferation was significantly higher in the groups in which Mecsina Hemostopper was used as a single material or in combination with graft material (P<.05). Histomorphometric evaluation showed that trabecular and osteoid thickness were significantly higher in all Mecsina application groups (P<.05). Conclusion: Mecsina Hemostopper was found to be an effective agent in increasing cell proliferation and providing more qualified bone formation. The combination of Mecsina and xenogeneic bone graft was found to be one of the most effective augmentation options for critical-size defects in rats. Mecsina Hemostopper could be used to get more qualified bone formation clinically, but more clinical research is needed in the future.
