Induction of Apatite by the Cooperative Effect of Amelogenin and the 32-kDa Enamelin

N. Bouropoulos and J. Moradian-Oldak
The 32-kDa enamelin and amelogenins cooperate to promote nucleation of apatite crystals, and the authors propose a possible novel mechanism of mineral nucleation during enamel biomineralization.

Interaction of Glass-ionomer Cements with Moist Dentin

C.K.Y. Yiu, F.R. Tay, N.M. King, D.H. Pashley, S.K. Sidhu, J.C.L. Neo, M. Toledano, and S.L. Wong
In the absence of water sorption from external sources, the existence of a distinct Si-rich phase within the air-voids of GIC-bonded dentin is probably caused by the permeation of water across the GIC-dentin interface.

Osmotic Blistering in Enamel Bonded with One-step Self-etch Adhesives

F.R. Tay, C.N.S. Lai, S. Chersoni, D.H. Pashley, Y.F. Mak, P. Suppa, C. Prati, and N.M. King
Osmotic blistering in enamel is probably caused by the low water permeability of enamel, allowing for water absorption into the interface, down an osmotic gradient between the bonded enamel and the external environment.

Influence of Resin Monomers on Growth of Oral Streptococci

Y. Takahashi, S. Imazato, R.R.B. Russell, Y. Noiri, and S. Ebisu
The apparent biomass increase during incubation with ethyleneglycol monomers is due to the polymerization of resin monomers to form vesicular structures attached to cells.
