Dental pulpal testing is a clinical and diagnostic aid used in dentistry to help establish the health of the dental pulp within the pulp chamber and root canals of a tooth. Such investigations are important in aiding dentists in devising a treatment plan for the tooth being tested. There are two major types of dental pulp tests.
A fracture is confined to enamel and dentin with loss of tooth structure, but exposing the pulp; Not tender upon percussion test; If tenderness is observed, evaluate the tooth for possible luxation or root fracture injury; Normal mobility; Sensibility pulp test is usually positive; Enamel-dentin loss is visible
Heat tests: Gutta percha can be heated and directly applied to the tooth to produce heat. [18] Electrical pulp test: Electric pulp testing (EPT) has been available for over a century and is used by dentists worldwide. It is used to determine the health of the pulp and pulp-related pain.
Periodontal abscesses are less common than apical abscesses, but are still frequent. The key difference between the two is that the pulp of the tooth tends to be alive, and will respond normally to pulp tests. However, an untreated periodontal abscess may still cause the pulp to die if it reaches the tooth apex in a periodontic-endodontic lesion.
Sequelae of a necrotic pulp include acute apical periodontitis, dental abscess or radicular cyst and discolouration of the tooth. [citation needed] Tests for a necrotic pulp include: vitality testing using a thermal test or an electric pulp tester. Discolouration may be visually obvious, or more subtle.
Pulp tests (test results of immature teeth can be misleading, as they are known to give unreliable results) [1] Check and see if there is an elevated, flat wear facet on the occlusal surface of the tooth [1] Test cavity which has an absence of pain sensation and has an empty pulp chamber/ canal. [1]
Cracked tooth syndrome could be considered a type of dental trauma and also one of the possible causes of dental pain.One definition of cracked tooth syndrome is "a fracture plane of unknown depth and direction passing through tooth structure that, if not already involving, may progress to communicate with the pulp and/or periodontal ligament."
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 ...
