A comparison of monopolar and bipolar electrical stimuli and thermal stimuli in determining the vitality of autotransplanted human teeth.
Of 33 autotransplanted maxillary canines, 13 responded to cathodal monopolar stimuli, 15 to bipolar stimuli and nine to a cold stimulus. Responses returned between seven weeks and 26 months after transplantation and indicated that the coronal pulp was reinnervated. There was no evidence that comparison of monopolar and bipolar stimulation might distinguish between the vitality of the coronal and radicular pulp, probably because monopolar stimuli did not excite nerves within the root. The thresholds to both forms of electrical stimulation were raised; the bipolar threshold was significantly higher than the monopolar. No transplanted teeth which responded to a cold stimulus did not also respond to an electrical stimulus.
