Abstract
The purpose of this study was to explore non-crystalline calcium phosphate glass as potential biomaterials in the regeneration of periodontal tissue. We prepared calcium phosphate glass with Ca/P ratio of 0.6 using the system CaO-CaF2-P2O5-MgO-ZnO and subsequent milling to 0.08∼555.7 μm (average size; 167.95 μm). In vivo evaluation of the prepared glass was investigated using beagle dogs by 1-wall intrabony defect model. They were sacrificed after 8 weeks and alanlyzed histomorphometrically. No root resorption or ankylosis were observed in the experimental group. It can be examined that the prepared glass were effective in cementum regeneration in the early healing stage by Mann-Whitney U test, while there were no statistical significant difference between experimental and control group in the amounts of junctional epithelium migration, connective tissue adhesion, and alveolar bone regeneration. Further study is required to control the flowability as well as reduce the absorption rate in vivo.
