TEM stereopair imaging of prepolymerized, methyl methacrylate, microvascular casts of germ‐free rats, with clinically healthy gingivae, demonstrated glomeruli in the gingivae of all molars. Glomeruli exist in the buccal, lingual and interproximal gingivae of the maxilla and mandible. Morphologically, glomeruli presented in different forms; principally as intertwining arterial and venous stalks surmounted by a multilobed glomerulus in the buccal and lingual aspects of the gingiva, and aggregations of complex glomeruli in the interproximal gingivae. Histologic examination of matched animals did not reveal any evidence of acute or chronic gingival inflammation with leukocyte infiltration. These findings provide support for the view that glomeruli develop as a normal component of the healthy gingivae and not primarily as a response to gingival inflammation.
