Diagnostic Accuracy of Cold, Heat, and Electric Pulp Tests: An In Vivo Study
In Brief
An observational study evaluating Pulp Sensibility Tests for Dental Pulp Disease and 2 related conditions. Completed, enrolled 175 participants across 1 site.
Detailed Summary
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.
Study Details
Timeline
Interventions
Cold Pulp Sensibility Test (Refrigerant Spray) Refrigerant spray (propane-butane) is applied to a cotton pellet and placed on the tooth surface for up to 15 seconds (or stopped when the patient responds). Response is recorded as present/absent. 2\) Heat Pulp Sensibility Test (Frictional Heat) A sterile rubber cup on a low-speed handpiece is applied to the tooth surface without water cooling for up to 7 seconds (or stopped when the patient responds). Response is recorded as present/absent. 3\) Electric Pulp Test (EPT) An electric pulp tester is applied with toothpaste as a conducting medium to the tooth surface. Current is increased gradually; the perception threshold value is recorded and compared with a contralateral control tooth. Response is recorded as present/absent per the predefined rule.
