“…In the past a great number of investigative works have been performed in an attempt to elucidate the microvasculature of the periodontal structures. Perfusion and injection techniques utilizing certaiti dyes, silicotie or colloid materials have been reported by Keller and Cohen (1955), Goldman (1956), Schubaok and Goldman (1957), Kindlova and Matena (1959), Cohen (1960), Adams (1962), Bernick (1962), Boyer and Neptune (1962), Castelli atid Dempster (1965) and Egelberg (1966a). Biomicroscopy has also been employed to examine particularly the gingival microcirculation (Staple 1955, Forsiund 1959, Staple and Copley 1959, Franke 1960, 1964a, 1964b, 1964c, and Kamijo et al 1964.…”

Plastic microspheres 15 ± 5 microns were injected into the right external carotid artery of five Squirrel monkeys. One animal was sacrificed at 1, 24 and 36 hours and two animals at one week. The jaws were removed, fixed, demineraized and sectioned bucco‐lingually. The vascular patterns in the connective tissue beneath the oral epithelium, epithelial attachment, “col” area and within the periodontal membrane were examined. The vascular tree supplying the oral epithelium was visualized as running perpendicular to the outer surface while that in the attachment area paralleled its epithelial surface. The “col” area, on the other hand, demonstrated a combination of both vascular patterns. The diameter of the terminal arterioles just beneath the epithelial basement membrane ranged from 13.6 to 20.4 microns and varied little in the three areas examined. The vessels within the periodontal ligament were connected into a net‐like plexus receiving its primary bloodsupply from vessels penetrating the lamina dura perpendicularly.

“…The gingival arterial rete of the rat was studied in great detail by use of histological and perfusion-corrosion methods by Kindlova and Mate'na. 21,22 These investigators have shown in their three-dimensional specimens that the gingival arterial rete is madeup of loops and arcades formed from anastomosis of arteries arising from the gingivae and the periodontium. Direct microscopic study of the microcirculation of the gingiva in man by F o r s~l u n d~~*~~ revealed loop and anastomosis patterns which could be identified and followed while physiological changes were taking place in the organism.…”

“…Thus, in the pulp, vascular units consisting of an arteriole with terminal branches and capillaries arise repeatedly and pass through a cycle of growth, remodeling and regression concur rent with changes in the migrating pulp [Kindlova and Matena, 1959;Zajicek, 1976;Moe et al, 1979], It is conceivable that vascular adaptation also takes place in the periodontium, since the capillaries of the moving enamel organ on the labial aspect of the tooth are supplied from arteries pene trating the adjacent non-migrating bone [Kindlova and Matena, 1959]. The intimate relationship of the capillary plexus and the enamel organ [Reith, 1959;Adams, 1962;Iwaku and Ozawa, 1979] renders it likely that in a forward movement of the enamel epithelia the capillaries move forward as well.…”

The capillary network of the enamel organ of the continuously growing mandibular incisor of the rat is supplied by a series of arteries which, after penetrating the bone, are disposed in a row in the periodontium along the tooth and linked together by anastomoses. The branches from these arteries are subjected to adaptive changes consistent with a forward movement of the capillaries in relation to the arteries. The mechanism which renders this movement possible appears to be the following: Each artery in the row supplies a section of the passing plexus by coupling and uncoupling short-lived arterioles, which go through a cycle of proliferation, elongation and degeneration. Proliferation takes place at the posterior end of the section, where new arterioles replace discarded arterioles from the preceding artery. By growing in length, the arterioles keep pace with the migrating capillary network. When the capillaries are within reach of the next artery, the arterioles disconnect. Thereafter they become obliterated and die in the intermediate zone of the periodontium, to which they have been gradually displaced by proliferation of the inner-tooth-related layer of the periodontal connective tissue.
