Morphology of gingival capillaries adjacent to complete crowns

Clinically normal gingivae adjacent to natural teeth did not exhibit dilated capillaries. The morphologies of the capillary loops were of the normal and mixed types. More than one fourth of the capillary loops in the gingivae adjacent to the complete crowns showed dilatation. The capillary loops were of the mixed and complex forms. Dilatation and complex capillary loops were found in the clinically normal gingivae adjacent to the complete crowns. The capillary microscope is an aid in the diagnosis of gingivae adjacent to complete crowns.
