background and aims. furcally-involved teeth present unique challenges to the success of periodontal therapy and influence treatment outcomes. this study aimed to assess to compare use of adm and connective tissue membrane in class ii furcation defect regeneration. materials and methods. 10 patient with 2 bilaterally class ii furcation defects in first and/or second maxilla or man-dibular molar...
Background: There are multiple methods for acceleration of bone healing. Bone marrow has been shown to contain osteoprogenitor cells. Objective: To determine the effect of percutaneous bone marrow injection on bone healing. Methods: 15 mature, 2-kg-weighing white New Zealand rabbits from both sexes were randomized into 3 groups: Group I: Only osteotomy of right radius was performed and a 5 mm b...
Background and purpose: This study was designed to identify the cells involved in the healing of the parietal bone defects after implantation of octacalcium phosphate (OCP) combined with bone matrix gelatin (BMG). Materials and Methods: Sixteen young male Sprague Dawley rats (5-6 weeks age) were used. A full thickness standardized trephine defects, 5mm in diameter, was made in the rat pari...
BACKGROUND It has been studied that the distribution of bone morphogenetic protein 2 is regular under bone defect situation. OBJECTIVE To observe the expression of bone morphogenetic protein 2 in rabbit radial defect site with different lengths. METHODS Forty-eight New Zealand rabbits were divided into two groups randomly. 0.5 cm bone defect and 3.0 cm bone defect were made by wire saw at t...
Background: This study was designed to investigate the process of bone formation caused by implantation of octa calcium phosphate (OCP) in rat tibiae. Methods: We used 25 young male Sprague-Dawley rats. A full thickness standardized trephine defect, 3-mm in diameter, was surgically created on the superior end of right and left tibia. Amount of 6-mg synthetic Octa calcium Phosphate was implanted...
Background and Objective: One of the major concerns of surgeons and patients is repairing of bone loss due to various factors. Many materials have been made to improve the quantity and quality of bone loss repair. The aim of this research was radiographic evaluation of healing process of human bone loss created after implantation of HECBMG (Human Endochondral Bone Matrix Gelatin) and DBM (Demin...
Background and Aim: Autogenous bone grafts are considered the gold standard although they have several disadvantages, leading to a search for suitable alternative graft biomaterials. This study evaluates the histological and histomorphometric properties of regenerated bone in defects in rabbits following the application of two commercially available xenografts (Bio-Oss and Osteon). Materials a...
Objective- The present study was aimed to evaluate repair of a critical segmental defect of rabbit femur using the rabbit’s femoral defects repaired by Zeolite and Zeolite/Collagen scaffolds Design- Experimental Study Animals- Forty-five mature male New Zealand white rabbits Procedures- The animals were randomly divided into three groups of 15 animals each. In the first group...
