Pulpal tests may be conducted via stimulation of the sensory fibres within the pulp (sensitivity testing) or by assessing pulpal blood flow (vitality testing). All available techniques are reported to have limitations in terms of accuracy and reproducibility [ 1 ] and therefore require careful interpretation in clinical practice.
Pulp vitality tests are positive and it is possible to preserve a healthy vital pulp. Irreversible pulpitis, in contrast, is characterised by a constant severe pain that arises without provocation. Characteristics may include sharp pain upon thermal stimulus, lingering thermal pain, spontaneity, and referred pain.
Vitality Test Sensitivity to temperature stimuli, particularly cold, often indicates the presence of proximal or near-pulp cracks. A positive response to both cold stimulation and bite tests is suggestive of a cracked tooth (Mathew S et al.,2012)
The pulse oximeter test is a more accurate way to test for necrotic pulps as it primarily tests for vascular health of the pulp as compared to its nervous response. [21] This method involves taking measurements of blood oxygen saturation levels, making it non-invasive and an objective way to record patient response regarding pulpal diagnosis. [20]
Pulpotomy is a vital pulp therapy; medicaments that can promote healing and preserve the vitality of the tooth should be placed after removal of the inflamed pulp. [ 12 ] In primary teeth medicaments such as formocresol, mineral trioxide aggregate , zinc oxide eugenol and calcium hydroxide can be used in pulpotomy.
The health of the dental pulp can be established by a variety of diagnostic aids which test either the blood supply to a tooth (Vitality Test) or the sensory response of the nerves within the root canal to specific stimuli (Sensitivity Test). Although less accurate, sensitivity tests, such as Electric Pulp Tests or Thermal Tests, are more ...
False positive COVID-19 tests—when your result is positive, but you aren’t actually infected with the SARS-CoV-2 virus—are a real, if unlikely, possibility, especially if you don’t perform ...
Vitality of teeth can be assessed through various means. Common tests would include ethyl chloride test or electric pulp test. Other examples of tests would be laser doppler flowmetry ( LDF ), pulse oximetry etc.
