Six different tetracalcium phosphate (TTCP) products were synthesized by solid state reaction at high temperature by varying the overall calcium to phosphate ratio of the synthesis mixture. The objective was to evaluate the effect of the calcium to phosphate ratio on a TTCP-dicalcium phosphate dihydrate (DCPD) cement. The resulting six TTCP-DCPD cement mixtures were characterized using X-ray di...

Calcium phosphate cements (CPCs) are being widely used for treating small scale bone defects. Among the various CPCs, brushite (dicalcium phosphate dihydrate, DCPD) cement is widely used due to its superior solubility and ability to form new bone. In the present study, we have studied the physical, mechanical, osteoclast-like-cells differentiation and in vivo osteogenic and vasculogenic propert...

Introduction Self-healing materials are being developed to improve the lifetime of materials used in various applications including coatings, adhesives, structural components, and even microelectronics. The approach of using microencapsulation for self-healing has been particularly promising with proven success in coatings and in bulk epoxy. However, the size of microcapsules limits their use t...

AIM: To explore the effect of orthokeratology (OK) fitting on retinal vessel density in low to moderate myopia adolescents by using optical coherence tomography angiography. METHODS: Children aged 10 14y with a cycloplegic spherical equivalent refraction −0.50 diopter (D) −5.00 D and astigmatism more than −1.50 were recruited. The enrolled divided into OK group spectacle group. During regular f...

Shuang S Chen and Joachim Kohn New Jersey Center for Biomaterials, Rutgers The State University of New Jersey, Piscataway, New Jersey 08854, United States. Statement of Purpose: Large bone defects resulting from trauma, tumor resection, congenital abnormalities or reconstructive surgery are challenging clinical problems that are usually treated with autografts and allografts. However, donor sit...

Calcium phosphate cement (CPC) sets in situ with intimate adaptation to the contours of defect surfaces, and forms an implant having a structure and composition similar to hydroxyapatite, the putative mineral in teeth and bones. The objective of the present study was to develop an injectable CPC using dicalcium phosphate dihydrate (DCPD) with a high solubility for rapid setting. Two agents were...
