Abstract

In this study, innervation of dental pulp in the tooth of green iguana (Iguana iguana) was investigated. Cryosections of dissected maxillae and mandibles were examined by free floating technique with anti PGP9.5 antibodies and anti-S-100 protein antibodies, and identified by electron microscopy. Immunoreactive fibers were observed in the pulp. They appeared to he a mixture of myelinated and unmyelinated fibers with small varicosities and were distributed in the pulp along the gap between the tooth and the jaw bone. Dental pulp of polyphyodonts has not been investigated much as replacement of teeth occurs in succession. These findings may promote investigations that could improve our understanding of the function of dental pulp in reptiles. Keywords: dental pulp, innervation, reptile, iguana.
