Abstract
Avg. chronaxie in normal teeth is 0.16 msec, a value which permits classification of the intradental nerve fibers among the elements of high functional differentiation. Chronaxie decreases from the anterior to the posterior teeth in the upper jaw (0.25 msec. first incisors to 0.15 msec. second molars). This difference is statistically significant. A comparative study of excitability between normal teeth and those presenting pulpitis was made. No difference was observed between both groups. Strength-duration curves of the intradental nerve fibers were detd. They are of simple development in all teeth. The homologous utilization times decrease from the first incisors to the second molars.Keywords
