Abstract
Background: This study evaluated pulp vitality of anterior permanent teeth using pulse oximetry (PO), which is already used for monitoring of patient’s and pulse rates (PR). Also we compared with ice tests and electric pulp test (EPT).
Methods: 9 teeth, endodontic treated, were selected as non-vital teeth group. 17 vital teeth were selected as control group. Our aim is to compare sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of ice test, electric pulp test and pulse oximetry, respectively. Pulse oximetry has two test results, and pulse rates. Also we calculated correlation and statistical significances by Pearson’s test between EPT and pulse oximetry.
Results: Sensitivity, specificity, PPV, NPV were calculated on each tests. Ice test has results of 1.00, 0.89, 0.94 and 1.00, respectively. EPT has results of 0.94, 0.78, 0.89 and 0.88 respectively. has results of 0.94, 1.00, 1.00 and 0.90, respectively. PR has results of all 1.00.
Conclusions: PO showed relatively accurate, stable and objective results on both and PR. Percentage of ability of accurate diagnosis for vital teeth is 94% for ice test, 89% for EPT, 100% for and PR. Percentage of ability of accurate diagnosis for non-vital teeth is 100% for ice test, 88% for EPT, 90% for and 100% for PR. In additions, PR could be more accurate and significant tests than .
