Movement of Dentinal and Pulpal Fluid Caused by Clinical Procedures

Abstract
The effects of some clinical procedures on the fluid contents of the dentin and pulp were studied in vitro. The method involved measurement of the movement of the meniscus in a tube and glass capillary filled with physiologic saline solution and attached to the root pulp of the extracted tooth. Drilling was found to produce expansion and an outward movement of fluid from the apex to the tooth.
