Immunohistochemical study of gamma-aminobutyric acid and bombesin/gastrin releasing peptide in human dental pulp.

This study investigated the presence of the putative peripheral neuromodulators Gamma-aminobutyric Acid (GABA) and Bombesin/Gastrin-Releasing Peptide (BN/GRP) in the human tooth pulp. Caries free and asymptomatic carious teeth were processed for paraffin embedding and sectioned at six microns. From each specimen, sections were stained with hematoxylin and… CONTINUE READING
