The effectiveness of inorganic calcifying solutions to remineralize enamel with subsurface demineralization decreased with saliva pre-treatments conducive to the formation of enamel pellicles. Greater reductions in remineralization rates occurred wit

Adsorption isotherms at 37°C were obtained for L -aspartic, L -glutamic, DL -α-amino-adipic, DL -α-amino-pimelic, succinic, and adipic acids, and L -arginine onto hydroxyapatite. A Langmuir-type adsorption model fitted the experimental results. Th

Water sorption isotherms for intact human enamel samples are reported at 25 and 50 °C. The isotherms display pronounced hysteresis consistent with the presence of constricted pores, some of which extend to molecular dimensions. The total water holdi

Salivary pellicles developed on extracted teeth favorably affected the degree and nature of enamel demineralization when the teeth were incubated in vitro with either of two pure strains of cariogenic Streptococcus mutans. The mechanism responsible f

Diffusion fluxes of two anionic species through hydroxyapatite membranes were found to be reduced up to 50% by the presence of adsorbed salivary pellicles developed on the membrane surfaces. By contrast, water fluxes were only marginally affected, in

Applications of APF and NaF solutions to extracted human teeth reduced the extent of enamel subsurface demineralization induced by colonization of S. mutans but were ineffective against demineralization by acid lactate buffers. It is concluded that t
