Application of the GTGO-AD procedure in the scanning electron microscopy of streptococci adhered to pellicle-coated dental enamel.
The scanning electron microscope (SEM) offers a direct and visually effective means of examining streptococci adhering to pellicle-coated dental enamel. The GTGO-AD (Glutaraldehyde-Tannic acid-Guanidine hydrochloride-Osmium tetroxide-Air-Drying procedure) has the advantage that critical point-drying or freeze-drying need not be employed. It was found that both the structural and spatial integrity of the adherent streptococci and the pellicle were maintained with the GTGO-AD procedure.
