Another look at behavioral sciences in dentistry: perspectives on collaborative clinical research.

This paper explores the collaborative research relationships between clinical dentists and behavioral scientists in dental education. The emergence of behavioral sciences in dentistry is discussed and attention is given to the nature of professional roles in collaborative clinical research. Components for a model for collaborative clinical research are specified based on the research experiences of behavioral scientists with colleagues in prosthodontics and orthodontics.

Enzyme separation techniques for the study of growth of cells from layers of bovine dental pulp.

Effects of the enzymes trypsin, papain, bromelains and ficin on bovine dental pulp tissue were studied. Minced or whole pulps were subjected to each enzyme at 17 degrees, 20 degrees and 37 degrees C for set time intervals, after which aliquots of supernatant fluid were removed for cell counts and viability tests. Pooled samples were subsequently cultured as monolayers in Eagle's MEM plus 10% calf serum.
