Background: The pulp tissue is confined within hard tissue boundaries and cannot be examined directly for
health evaluation. Hence, its assessment is usually based on sensibility tests. Accurate diagnosis of the pulpal
status requires evaluation with combination of sensibility tests. The objective of this study was to assess the
mutual agreement between the electric pulp test and cold test in determining pulp vitality.
Methods: Total 106 patients, aged 18 to 30 years, attending the dental OPD of Operative Dentistry/Endodontics department; Dr. Ishrat-ul-Ibad Institute of Oral Health Sciences, Karachi were selected for the study. The
cold and electric pulp tests were used to determine the presence or absence of tingling sensation. Teeth
were marked as vital in presence and non-vital in absence of any tingling or painful response. Agreement
between these two tests was calculated using SPSS-18. To calculate the mean and standard deviation,
descriptive statistics were applied for quantitative variables. For qualitative variables, frequencies and
percentages were calculated. Kappa statistics was applied for agreement between electric pulp and cold
test.
Results: The cold test showed that 70.8% of the teeth were vital and 29.2% were necrotic. The electrical pulp
test showed that 74.5% were vital and 25.5% were necrotic. The outcome showed 83.0% agreement
between the tests; with kappa value of 0.574 which provided sufficient agreement with p-value=0.000.
Conclusion: There was a high agreement found between the cold test and electric pulp test. Assessment of
pulp vitality would be more accurate when EPT and Endo frost are used in combination.
