The effect of pulpectomy on the longitudinal distribution of nerve fibres in the periodontal ligament of the ferret.
The innervation density of the periodontal ligament was measured at a series of levels around the mandibular canines of 6 ferrets, in 5 of the which the pulp of one of each of these pairs of teeth had been removed 3 months earlier. In control (unoperated) teeth the density of innervation was greatest in the apical third and lowest in the coronal third. The pattern around the pulpectomized teeth was similar. There was no statistically significant difference between density values for control and operated teeth. Pulpectomy thus does not affect the incidence or distribution pattern of nerves in the periodontal ligament.
