Abstract/OtherAbstract:
The immunohistochemical occurrence of several different neuronal markers has been investigated in human gingiva with phenytoin-induced overgrowth. The material was compared to gingival material taken following surgical orthodontic treatment. Gingiva obtained from the phenytoin-treated groups seemed to have a reduced number of neurofilament (NF) immunoreactive nerve fibers in the propria compared to control material. In both phenytoin as well as control gingiva sparsely distributed, thin, calcitonin gene-related peptide (CGRP) and substance P (SP) immunoreactive fibers were found in the propria. No obvious differences between the two groups could be observed for CGRP and SP. Immunoreactive cells for somatostatin (SOM) with a dendritic cell shape were found in the propria in both groups, sometimes in densely packed clusters. A tendency for increase of SOM-immunoreactive cells in the phenytoin-treated gingiva was observed. A few gamma-melanocyte stimulating hormone (gamma-MSH)-immunoreactive cells with a round appearance were found in control as well as phenytoin-affected gingiva. In one instance, however, a heavy gamma-MSH-immunoreactive cell infiltration was seen in the phenytoin sample. No immunoreactivity in either the phenytoin-treated group or in the control group was seen for proctolin or galanin. The results indicated that gingiva with phenytoin-induced overgrowth has a reduced innervation density revealed with NF immunohistochemistry.
