The Mechanism of Dental Plaque and Dental Calculus Formation by Fibronectin 7. Inhibition of Seeded Crystal Growth of Hydroxyapatite in Metastable Calcium Phosphate Solution by Fibronectin

Fibronectin isolated from human plasma by affinity chromatography on gelatin-Sepharose 4B was demonstrated to inhibit seeded crystal growth of hydroxyapatite in the metastable calcium phosphate solution.

More Information
Summary:Fibronectin isolated from human plasma by affinity chromatography on gelatin-Sepharose 4B was demonstrated to inhibit seeded crystal growth of hydroxyapatite in the metastable calcium phosphate solution. It was also demonstrated that the inhibition was brought about direct adhesion to hydroxyapatite crystals in addition with binding to calcium ion. The adhesion to the crystals by fibronectin was predicted to be formed by repeating dissociation and fusion. Stated reversely, these results indicate that the fibronectin in salivary secretion play a role as materials in the early stages of formation of acquired enamel pellicle.
