The efficacy of thermal and electrical tests to register pulp vitality

The present study was conducted to evaluate the ability of thermal (green endo ice and endo ice F) and electrical tests to register pulp vitality. One hundred and thirty seven teeth with unknown pulp status was used in this study, ninety seven teeth were with vital pulp. Sensitivity, specificity, negative and positive predictive values were calculated. The sensitivity of Green endo ice was 0.99, whereas for endo ice F it was 0.69 and 0.96 for electrical pulp tester. The predictive value for sensitive reaction representing a vital pulp was 99% with green endo ice, and only 70 % for endo ice F and 88% for electrical pulp testing. Green endo ice presents the lowest intra pulpal temperature with 99% sensitivity.
