Abstract

Fracture repair is a constant clinical challenge, and finding a method to promote and improve restoration is a primary goal for researchers. This is examined from various perspectives, such as fewer complications, increased speed, and cost-effectiveness. The present study aimed to investigate the effectiveness of eggshell powder, compared to the commercial form of demineralized bone matrix (DBM), in critical-size defects in rat calvarial bone. In this study, 40 adult male Wistar rats were selected and randomly divided into four groups of 10. The first group was the control group (C), the second was the eggshell powder group (E), the third was the DBM group (D), and the fourth was the one simultaneously receiving eggshell powder and DBM (DE). In these groups, a 5 mm diameter defect was created in the calvaria using a trephine. All animals received the appropriate treatment for their group. Each group was then divided into two subgroups of five. On days 30 and 60 post-surgery, these subgroups were euthanized, followed by sampling and histopathology examinations. After evaluating the repair percentage using Quick Photo software, the DE group had the highest repair percentage on days 30 and 60. Groups E and D had similar recovery percentages, with group D having a slightly higher one. There was a significant difference between all three groups and the control group. In conclusion, eggshell powder may potentially serve as a suitable substitute for some transplants.
