BACKGROUND: To evaluate the efficacy of pulse oximeter as a pulp vitality tester. MATERIALS AND METHODS: The sample group consisted of 60 patients of age 15 to 30 years with normal maxillary anterior teeth. Thirty nonvital teeth with complete endodontic fillings were tested as control group. Systemic oxygen saturation values from the patient's fingers served as the control sample for comparison of pulp oxygen saturation values. Readings were recorded on index fingers first; teeth were then evaluated by placing sensor onto the tooth. RESULTS: Nonvital teeth recorded oxygen saturation values of 0%. The mean value for central incisor was 85.11 (SD ± 2.07), for lateral incisors 80.21 (SD ± 2.03) and for canines 89.55 (SD ± 1.09). Their control values (patient's index fingers) averaged 95.88% (SD ± 0.66). Pearson's correlation analysis showed a correlation of 0.11 for central incisors, 0.19 for lateral incisors and 0.12 for canines. CONCLUSION: This study confirms that pulse oximeter is effective equipment for pulp vitality testing. Pulse oximeter evidences the actual method of evaluating the pulp vitality compared to contemporary methods. How to cite the article: Sadique M, Ravi SV, Thomas K, Dhanapal P, Simon EP, Shaheen M.
