Blood flow and vascular pressure in the dental pulp

Abstract

The present summary is a review and a discussion of the following papers (I-V), submitted as partial fulfillment of the requirements for the degree of Doctor Odontologiae at the University of Bergen. I. Blood flow in the dental pulp in dogs measured by local H2 gas desaturation technique. Arch. Oral Biol. 1975, 20, 73-79. Co-author: K. Aukland II. The effect of variations in arterial blood pressure and baroreceptor reflexes on pulpal blood flow in dogs. Arch. Oral. Biol.1975, 20, 345-349 III. Effect of vasodilating drugs on external carotid and pulpal blood flow in dogs: "Stealing" of dental perfusion pressurE. Acta Physiol. Scand. 1976, 97, 75-87 IV. Nervous control of blood flow in the dental pulp in dogs. Acta Physiol. Scand. 1978, 104, 13-23. Co-author: G. Naess V. Microvascular pressure in the dental pulp and gingiva in cats. Acta Odontol. Scand. 1979, 37, 161-168. Co-author: G. Naess Other papers are referred to in the conventional manner.

Effects of age, sex, and blood pressure on the blood flow velocity in dental pulp measured by Doppler ultrasound technique

“…used intravital microscopy to study the profiles of PBF and reported that the PBFV was five times higher in the arterioles than in similar‐sized venules. The regulation of PBF was found to be controlled by systemic BP, as well as by neuronal, local, and humoral mechanisms …”

A new method for the non‐invasive measurement of pulpal blood flow

“…These three parameters have been examined in many ways: in animals, for example, by histology, tissue pressure measurements, isotope clearance, radiolabelled microspheres and photoplethysmography. For obvious reasons, investigations on human teeth tend to be rather more restricted, with post-extraction histology providing the majority of information; this has been reviewed by Tonder (1980).

A Case Report of a Patient with Raynaud’s Phenomenon Undergoing Multiple Endodontic Procedures

“…The vitality of the pulp depends upon its blood supply. Tonder (3) found that only terminal arterioles enter the pulp and that the collateral circulation is distinctly limited. If the blood flow should be compromised in an arteriole in the terminal circulation of the pulp, a localized necrosis might occur because of the limited amount of collateral circulation available.…”
