The movement of radioactive molecules across dentine in vivo in the dog.

Using a technique for measuring the movement of circulating molecules across the odontoblast-dentinal complex, the movement of water and alpha-aminoisobutyric acid through dentine and into a flow cell prepared on the tooth is described. The movement of water depended on dentine thickness, and varied from 0.40 microliter/min per cm2 in a flow cell overlying an average thickness of 0.74 mm of dentine, to 1.23 microliter/min per cm2 in a flow cell with a dentinal floor of 0.40 mm average thickness. The data suggest that alpha-aminoisobutyric-acid concentrations were lower in dentinal fluid than in blood plasma.

Trace fluoride and its role in enamel mineralization.

A highly reproducible seeded crystal growth method has been used to study enamel mineralization in the presence of traces of fluoride ion. The resulting increased rate of remineralization over a range of calcium phosphate supersaturation may be attributed to the formation of surface fluorapatite.
