The aim of the present controlled clinical study was to compare the clinical response of grafting superporous hydroxyapatite (HAp) granules to superporous HAp blocks in the treatment of human intrabony periodontal defects. Twenty interproximal intrabony osseous defects in 20 healthy, non-smoking subjects diagnosed with chronic periodontitis were included in this study. These twenty subjects wer...

To study cellular characteristics of human cementoblasts using a cellular model is important for understanding the mechanisms of homeostasis and regeneration of periodontal tissues. However, at present no immortalized human cementoblast cell line has been established due to limitation of the life span. In the present study, therefore, we attempted to establish human cementoblast-like cell lines...

Static bone scan was performed in 46 patients for evaluation of ocular Hydroxyapatite Vascularization. Study Findings indicated that bone scan, with TC-99m MDP is an appropriate method for evaluation of Hydroxyapatite Vascularization and for estimating the time For peg insertion into the Hydroxyapatite implant. Our study showed proper Hydroxyapatite Vascularization when the ratio of activ...

The present work deals with a study on the physical characteristics of stoichiometric hydroxyapatite microspheres produced by spray-drying process through different operating conditions. Obtained are intended to be used as powder feedstock in bed selective laser processing additive manufacturing technologies where flowability and particle size distribution special importance. powders at paramet...
