Challenges of bioengineering and endodontics
Stem cell research and scaffolding are now the buzz words in basic science pulp researches. The endodontic community needs to enhance its clinical understanding of the vital pulp and dentin, and embrace new treatment modalities. Several regenerative techniques have been described, while therapies involving stem cells, growth factors and scaffolds have been proposed. Each technique has its own advantages and...

Ultrastructural changes in the tight intercellular junctions of the endoneurial blood vessels following sural nerve crush injury in rats
The objective of this study was to investigate the ultrastructural changes in the tight intercellular junctions of the endoneurial blood vessels after nerve injury. Twenty-one adult male Sprague-Dawley rats were used in the study (3 animals as a control group and left sural nerves of 18 animals were subjected to the crush). At intervals of 1, 2, 3, 4, 5 and 6 weeks after crush, 3 rats /sitting were killed and the fixed...
