About this trial
The objectives of this study are to determine the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of laser Doppler flowmetry in determining the vitality of teeth and comparing with those of electric pulp testing and cold testing.
Eligibility criteria

Criteria for inclusion in the study will be that the individual has teeth that require endodontic treatment and patient is willing to undergo two additional vitality tests which will take about 20 minutes of additional time.
Disqualifiers
No group of special subjects or vulnerable population is being targeted in this study.
Trial population
Patients that need endodontic treatment will have a consultation visit first. In most cases, the endodontic treatment will be provided at a subsequent visit.

The number of teeth showing the true positive, true negative, false positive, and false negative after pulp vitality testing
Patients who present to the endodontic clinic for a consultation visit prior to treatment. The patient will have three types of pulp vitality tests done on the tooth that is to receive endodontic treatment. The number of teeth that show the true positive, true negative, false positive, and false negative after pulp vitality testing will be measured. For example, a tooth that is diagnosed nonvital based on the pulp vitality testing will be confirmed when endodontic treatment is performed. If there is a discrepancy, it can be counted as false negative. When a tooth is diagnosed vital based on the pulp testing and confirmed to be vital, it can be counted as true positive. When a tooth is diagnosed vital based on the pulp testing and confirmed to be nonvital, it can be counted as false positive. When a tooth is diagnosed nonvital and confirmed novital, it is counted as true negative.
