TY - JOUR TI - Radiographic Evaluation of the Effect of Vitamin D3 Supplementation on Regeneration of Calvarial Bone Defects in Rats AB - Aim: The present study was aimed to evaluate radiographically the effect of orally administered vitamin D3 on guided bone regeneration in calvarial critical size defects (CSD) in rats. Methods: Two calvarial CSD were created in 12 male Sprague-Dawley rats. One of the defects was left empty (E defect), while the other one was treated with deproteinized bovine bone graft and collagen-based resorbable membrane (GM-filled defect). Following surgical intervention, rats were randomly assigned into two groups; the control group was administered distilled water, and the test group was treated with 2 µg /kg vitamin D3 by gavage once a day for 8 weeks. Radiological images were obtained from rats on 4th and 8th weeks. The area fraction of newly formed osteoid was determined using Image Fiji Analysis Software. Results: The percentages of area fraction in the GM-filled defects were statistically higher than the E defects in both study groups at 4th and 8th weeks (p AU - Varlihan, Gulce Nil AU - Agrali, Omer Birkan AU - YILDIRIM, HATICE SELIN AU - DEMIRCI DELIPINAR, Sibel AU - Kuru, Leyla AU - Öztürk Özener, Hafize DO - 10.33808/clinexphealthsci.1262852 PY - 2023 JO - Clinical and Experimental Health Sciences VL - 13 IS - 4 SN - 2459-1459 SP - 769 EP - 775 DB - TRDizin UR - http://search/yayin/detay/1218073 ER -
