Pulp Vitality Tests: Laser Doppler Flowmetry, Pulse Oximetry, Percussion (Tooth Slooth), Test Cavity 

Pulp testing involves attempting to make a determination of
the responsiveness of pulpal sensory neurons. Laser Doppler Flowmetry (LDF) is a non-invasive method of assessing and measuring the blood flow of pulp tissue. It is based on the principle that the light beam’s frequency will shift when hitting moving red blood cells but will remain unshifted as it passes through static tissue. Pulse Oximetry is a non-invasive method to measure the oxygen concentration in the blood & the pulse rate, in which the light absorbed depends on the ratio of oxygenated and deoxygenated hemoglobin in the blood. Percussion & Bite test include the use of Tooth Slooth and FracFinder. Test cavity is an invasive, irreversible test which
can be used in case of full coverage crown. Selective anesthesia involves periodontal ligament (intraligamentary) injection beginning from distal sulcus of the posterior most tooth.
