Abstract:
:Enamel and cementum pellicles form by different adsorption of salivary and serum components to the tooth surface. The authors compared the constituents of surface pellicle formed on human enamel and cementum under three conditions: (1) natural pellicle, present on extracted teeth, which was formed by prolonged exposure to human salivary and serum components in vivo; (2) short-term in-vivo pellicle, formed by exposing enamel and cementum slabs to the oral environment for 0-60 min; (3) in-vivo pellicle, formed by incubating enamel and cementum slabs in a 1:1 mixture of parotid and submandibular/sublingual saliva for 0-60 min. Pellicle composition was characterized by external radiolabelling techniques specific for exposed carbohydrate (sialic acid and galactose) and amino-acid (tyrosine) residues. There were differences between cementum and enamel in the electrophoretic profiles of natural-pellicle components; notably, a major 180 kda 3H-labelled sialoglycoprotein, unique to the cementum pellicle, had the same electrophoretic mobility as the low-molecular-weight mucin from human submandibular/sublingual saliva. After alkaline-borohydride treatment, 3H-labelled natural-pellicle oligosaccharides chromatographed in the di- to tetrasaccharide region of a Bio-Gel P-2 column. The most prominently labelled components of short-term enamel and cementum pellicles in vivo and in vitro had the same electrophoretic mobility as the low-molecular-weight salivary mucin. The pellicle components formed in vitro, unlike those formed for the same period of time in vivo, were rapidly desorbed from the cementum, but not from the enamel surface. We conclude that: (1) external labelling techniques are useful for obtaining a profile of pellicle components; (2) submandibular/salivary mucins are major constituents of salivary pellicles on tooth surfaces; (3) glycoproteins that carry low-molecular-weight, sialic-acid-containing saccharides are important determinants of pellicle surface properties [corrected].
