Purpose/Objectives: To create a more realistic basis for diagnostic classifications by determining the relationship between the clinical signs and symptoms and the actual histological state of the pulp.

Materials & Methods: 166 human teeth that were scheduled for extraction were examined clinically (EPT, thermal test, and x-rays) prior to extraction. Post – operatively the teeth were prepared and examined histologicaly.

Results: Examiners placed the teeth into one of the following histologic categories. Intact-uninflammed pulp Atrophic pulp Intact pulp with scattered chronic inflammatory cells (transitional stage) Chronic partial pulpitis a. With partial liquefaction necrosis b. With partial coagulation necrosis Chronic total pulpitis c. With partial liquefaction necrosis d. With partial coagulation necrosis 6. Total necrosis

Author’s Conclusion: There is no complete categorization method of pulpal disease because of overlapping as well as differing disease states in different areas of the pulp. This results in extreme difficulty and confusion when trying to correlate clinical diagnosis with the actual histological state of the pulp.

Validity of Conclusion: The conclusion is valid based on the fact that it was nearly impossible to correlate the clinical and histological findings.

Reviewer’s Comments: This article has very important findings but could have been presented in an easier and more organized manner.
