Objective The objective of this randomized controlled trial was to evaluate the radiographic changes and histologic healing following alveolar ridge preservation (ARP) using autogenous whole tooth (AWTG), test group, versus demineralized dentin graft (ADDG), control group. Material methods Twenty non-molar teeth indicated for extraction were into two groups (n = 10/group). Extracted prepared AW...

OBJECTIVES To determine whether autogenous tissue-engineered cartilage grafts can be synthesized in predetermined shapes, to compare tissue-engineered cartilage with native cartilage with respect to histological characteristics and biomechanical properties, and to demonstrate how multiple transplantations affect tissue-engineered cartilage. DESIGN Controlled, prospective animal study. SUBJE...

Patients with chronic kidney disease (CKD) stage 4 or 5 have the option of kidney transplantation, hemodialysis (HD), peritoneal dialysis (PD), or conservative management.1 National Kidney and Urologic Disease Information Clearinghouse reported that in 2007, there were 368, 544 U.S. residents with ESRD who were receiving dialysis, of whom 341, 264 were undergoing HD.2 Quality of life and long-t...

Tooth germs of first molars from fourto six-day old mice were transplanted heterotopically into the connective tissue under the dorsal skin of adult syngeneic recipients. The fate of the transplants was studied by histologic staining, vital staining with procion dyes, and autoradiography. Together these methods provided the following picture of the development of the transplant. Extraction of t...

recent tendencies in concrete technology have been towards to high- performance concrete with a low water-cement ratio. however, high performance concretes have some problems. one of the problems is early-age cracking due to autogenous shrinkage. this study presents the results of an experimental investigation carried out to evaluate the autogenous shrinkage of high-strength concrete. accordin...

109 Bone grafting is an important aspect of foot and ankle surgery.1 Despite the long history and widespread use of bone grafts and substitutes,2 there have been few studies documenting patterns of utilization of bone grafting by podiatric surgeons. A survey on the use of bone grafts among orthopedists was reported in 1984 by Miller et al.3 The present study was undertaken in order to determine...
