Studies on the organic polyanionic constituents of human acquired dental pellicle. 1986

G Embery, and T G Heaney, and J B Stanbury

Extracts of acquired dental pellicle were obtained by a two-step procedure. Pellicle formed on cleaned teeth was first extracted using 2 M CaCl2, and the remainder then removed by scraping followed by solubilization in 5 per cent (w/v) EDTA. The 2 M CaCl2 extract contained high-molecular-weight glycoprotein which was present in only trace amounts in the EDTA extract. Cellulose-acetate electrophoresis of both extracts revealed low-molecular weight protein which contained phosphate. This protein tentatively identified as a phosphoprotein, disappeared as the pellicle matured. The findings have implications in relation to early bacterial colonization of the tooth surface.

D044622	Dental Pellicle	A thin protein film on the surface of DENTAL ENAMEL. It is widely believed to result from the selective adsorption of precursor proteins present in SALIVA onto tooth surfaces, and to reduce microbial adherence to the TEETH.
