To address this gap in knowledge, we investigated the expression of VGLUT1 and VGLUT2 in the rat dental pulp and trigeminal ganglion (TG) in a model of dental pulp inflammation, induced by complete Freund’s adjuvant (CFA), using light microscopic immunohistochemistry, quantitative analysis of VGLUT1− and VGLUT2− immunopositive axons and somata, and Western blot analysis. The gene discussed is SLC17A7; the disease is pulpitis.
