Which of the following can be used for dentinal hypersensitivity?

In a clinical study using the primer of the original Gluma adhesive system, an aqueous solution of 5% glutaraldehyde and 35% HEMA, currently marketed as Gluma Desensitizer; the desensitizing solution was applied to crown preparations. The authors concluded that Gluma primer reduced dentin sensitivity through a protein denaturation process with concomitant changes in dentin permeability. This theory recently has been supported by studies using confocal microscopy, which found the formation of transversal septa occluding the dentinal tubules following application of Gluma Desensitizer.
