Evaluation of the Effects of Utilizing Carbon Dioxide as a Pulpal Test. Part I. In Vitro Effect on Human Enamel Surface.

Abstract

An effective method fo clinical pulp testing, carbon dioxide snow was evaluated in vitro to determine the effect of the rapid thermal change on the enamel surface. The buccal surfaces of fifteen teeth were subjected to a total of two minutes each of the cold test. No new cracks or fissures were seen after cold application when the surfaces were examined by a profile analyzer, or replicas of the surface by a scanning electron microscope. In only one of nine pre-existing surface fissures could any possible change be shown and this occurred only after the full 2 minutes of testing. In respect to use on enamel, carbon dioxide appears to be a safe test. (Author)
