P>This study was designed to evaluate and compare the reliability of laser Doppler flowmetry (LDF), pulse oximetry (PO) and electric pulp tester (EPT) for assessing the pulpal status as a vitality test method by calculating their sensitivity, specificity and predictive values. Data were collected from 59 pairs of maxillary anterior teeth (38 pairs of central, 21 pairs of lateral incisors) in 51 patients (range 12-18 years, mean age 14 center dot 6 +/- 1 center dot 73 years, 28 women, 23 men). The teeth with complete endodontic fillings constituted the study group, and the healthy, contralateral teeth of the same patients were constituted the control group. The calculated sensitivity was 0 center dot 915 for the EPT and 0 center dot 813 for the PO. And the specificity of EPT was 0 center dot 881 and PO was 0 center dot 949. The difference between the LDF values obtained from the study, and control group was statistically significant (P = 0 center dot 0001). The findings of this study indicated that LDF can reliably discriminate the vitality of the teeth with a sensitivity and specificity of 1 center dot 0 for this sample. Laser Doppler flowmetry was found to be a more reliable and effective method than PO and EPT of assessing the pulpal status of human teeth.
