Diagnostic Accuracy of Cold, Heat, and Electric Pulp Tests

The goal of this observational study is to evaluate the diagnostic accuracy of cold, heat, and electrical pulp tests in adults with teeth suspected of requiring endodontic treatment. The main questions it aims to answer are: 1. How accurately do cold, heat, and electrical pulp tests identify pulp vitality? 2. How do these tests compare with direct visual inspection of pulp bleeding during endodontic access (reference standard)? Participants attending The University Endodontics Clinic with at least one tooth indicated for endodontic access will receive cold, heat, and electrical pulp testing as part of the clinical examination. The test responses will be recorded and compared with the presence or absence of pulp bleeding observed directly after access cavity preparation.
