The distribution of blood vessels during molar eruption in the mouse was disclosed by means of their histochemical reactions for ATPase activity, using the reversible inhibition test of Padykula and Herman (1955), at pH 9.4, after EDTA‐decalcification of the specimens. A rich vascular supply was registered between the epithelial protrusions lateral and occlusal to the crowns, in the stellate reticulum and lining the external dental epithelium. Large vessels were found in the narrow connective tissue regions above the erupting lingual cusps. No joining proliferation of the oral and dental epithelia was observed before their fusion. A significant ATPase activity seemed to accompany an extensive vascularization, an increased keratinization, and a possible induction for oral epithelial proliferation and migration.
