Mucus coat was isolated from oral epithelial surfaces of caries-resistant and caries-susceptible subjects, analysed for content and composition of lipids and mucus glycoproteins, and evaluated for physico-chemical characteristics. The mucus coat from caries-resistant subjects had a protein content similar to that of the caries-susceptible group but a higher content of carbohydrate and a lower content of lipids and covalently bound fatty acid. The carbohydrate component was mainly mucus glycoprotein, which accounted for 28.4% of the dry weight of caries-resistant mucus and 25.3% of caries-susceptible mucus. By chromatographic analysis on Bio-Gel A-50, both types of preparations had high (Mr approximately 2000 kdalton) and low (Mr approximately 300 kdalton) molecular-weight mucus glycoproteins. In the caries-susceptible mucus coat these two glycoproteins were in similar proportions, whereas the low molecular-weight glycoprotein predominated in caries-resistant mucus. In both preparations, the high molecular-weight glycoprotein was characterized by a high content of carbohydrates, associated lipids and covalently bound fatty acids, whereas the low molecular-weight glycoprotein was richer in protein and contained lesser amounts of associated and covalently bound lipids. Although the low molecular-weight glycoprotein showed only minor compositional differences with caries status, the high molecular-weight glycoprotein of the caries-resistant group had a 2.5 times lower content of covalently bound fatty acid, a 1.3 times lower content of associated lipids and contained 1.2 times more sulphate and sialic acid then that of the caries-susceptible group.(ABSTRACT TRUNCATED AT 250 WORDS)
