Comparative ultrastructure evaluation of particle biomaterial of ovine origin

Journal Title: RSBO - Year 2011, Vol 8, Issue 1

Abstract

Introduction: Xenogenic bone grafting biomaterials have been vastly studied. Easy clinical use and low cost have attracted professionals and patients. Alternatively to bovine biomaterial, ovine biomaterial can be developed. Objective: To compare by scanning electron microscopy the ultrastructure of a particle ovine biomaterial to equine and bovine commercially available biomaterials, besides to human bone from a tissue bank. Material and methods: Ovine mandibular bone, from a local sheep farm, was ground and submitted to a chemical and physical sterilization protocol to be compared to different biomaterial particles. Images were obtained and evaluated according to the quantity and area values of porosities (χ2), visual surface roughness, and Ca/P ratio. Results: There was no statistical difference among the sample images; however, the bovine particles presented marked porosities and roughness. Conclusion: In relation to porosity, experimental ovine bone presented closer characteristics to human bone than equine and bovine. Regarding to surface roughness, equine bone was the most similar to human bone, followed by ovine and bovine. Concerning to Ca/P ratio, ovine bone presented the lowest and most distant value from human bone, followed by equine and bovine.
