Abstract
Respiratory inhibition by cyanide was measured in bovine dental pulp slices and in bovine kidney cortex slices. Although inhibition in kidney slices was approximately 80%, inhibition in dental pulp was about 60%. The lower level of respiratory inhibition in pulp by cyanide is indicative of a lower concentration of cytochrome oxidase in this tissue. This is compatible with previously observed metabolic characteristics suggestive of a less highly developed respiratory mechanism in dental pulp.
