The response of caries‐free, unfilled teeth to electrical excitation: a comparison of two new pulp testers

Abstract

Summary. A total of 845 sound teeth in 54 patients were stimulated by one of two new electric pulp testers to obtain pain perception threshold values. The age range of the patients was 18 to 27 years and only incisor, canine and premolar teeth were studied. Both testers were found to produce threshold responses over a wide range of control settings in groups of similar teeth. From the results it is clear that there is no consistent threshold excitation value for teeth with intact‐uninflamed pulps.
