Abstract
Two hour in vivo formed enamel pellicle samples and paraffin wax-stimulated saliva samples were collected from 10 volunteers for analyses of glucosyltransferase activity (GTF). GTF activity was recorded by monitoring incorporation of radioactivity from 14C-glucose labeled sucrose into glucan. Pellicle and saliva samples from all 10 subjects demonstrated GTF activity. The GTF activity in the pellicle samples was highest in subjects with high GTF activity producing adhesive glucan in saliva.
