Classification and diagnosis of pulpal pathoses.

The purpose of this article has been to review some concepts regarding the histophysiology and histopathology of the pulpodentinal complex and the "language of classification." Although there may not be agreement on the "language" presented here, there can be no disagreement that from a clinical perspective, knowledge and appreciation of the ideas presented can be helpful in determining pathologic presence. In reaching the ultimate clinical decision, the following questions must be answered: Are we dealing with a pulpal disease that is potentially reversible? If treatment is necessary do we treat the pulp or the pulp canal?
