Indiana University-Purdue University Indianapolis (IUPUI) / A study was made to determine if heterogenous dentin, devoid of its antigenic potential, would stimulate reparative dentino-genesis in the dental pulp. The teeth of two monkeys were capped with bovine dentin mixed with methyl cellulose and histologic analysis was made at 21 and 42 days post-operatively. At the 21-day interval, seven of the 17 teeth capped with the experimental material were successfully repaired with atubular dentin. The remaining 10 teeth showed varying degrees of inflammation and repair. The teeth of the second animal (42 days) were stained for bacteria as an additional diagnostic tool. A direct correlation was found between delayed healing and inflammation and presence of bacteria in the pulp. No bacteria were found in pulps which were successfully repaired. It was concluded that anorganic bovine dentin seemed to induce calcific repair of the dental pulp in the absence of bacteria. Autogenous dentin chips appeared to have the same effect. The importance of including a bacteriologic stain in the histologic analysis of pulp capping studies was demonstrated.

During development, CNC cells respond to the environmental cues to migrate and differentiate into the different cell types that contribute to the formation of craniofacial structures and the peripheral nervous system. The Eph family of receptor tyrosine kinases and their ligands, the ephrin molecules, play an essential role in the migration of neural crest cells during development and postnatal stem cell (SC) niche maintenance. "The present study demonstrated multiple Eph receptors expressed primarily on DPSC within the perivascular niche, while the surrounding pulp tissue expressed ephrin-B ligands. EphB/ephrin-B bi-directional signalling inhibited DPSC attachment and spreading, while DPSC migration was restricted through uni-directional ephrin-B1 activated EphB forward signalling in vitro. Furthermore, we observed that ephrin-B was down-regulated in diseased adult teeth compared to paired uninjured controls. Collectively, these studies suggest that EphB/ephrin-B molecules play a role in restricting DPSC attachment and migration in order to maintain DPSC within their SC niche under steady-state conditions. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1274738 / Thesis (Ph.D.) -- University of Adelaide, School of Molecular and Biomedical Science, 2007
