Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The FLUX value for the pulpal blood flow.It will be measured for a vital tooth and non vital tooth at a single time point only.After which, a statistical ratio is calculated to get the sensitivity/specificity. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Repeatability of the machine will be calculated using FLUX values. 2. A second measurement on 20% of the sample size will be done to calculate the reliability by comparing FLUX values. | — |
