[10] [11] False negative results occurs when innervated teeth do not respond to sensibility testing. Such can occur in individuals who have recently traumatised teeth, teeth with incomplete root development, teeth with heavy restorations or teeth that have significantly reduced pulp size due to production of tertiary or sclerotic dentine. [12]
The overall pulp cavity may become smaller by the addition of secondary or tertiary dentin and cause pulp recession. The lack of sensitivity associated with older teeth is due to receded pulp horns, pulp fibrosis, the addition of dentin, or all these changes. Restorative treatment can be performed without local anaesthesia on older dentitions. [2]
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 ...
Pulp sensibility tests are routinely used in the diagnosis of pulpitis. Pulp testing is combined with information taken from history, examination and other special investigations such as radiographs in order to reach a diagnosis. Pulp sensibility tests assess the pulp's sensory response to a stimulus. There are three general types:
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."
Johnny Depp fans have noticed that big change appears to have fixed his “rotting” teeth.. A clip of the actor on holiday in the Bahamas has been shared by a bartender from Lorraine’s Café ...
A pulp vitality test such as a cold test or electric pulp test can aid in diagnosis, since COD generally does not compromise pulp vitality. [6] COD can be found in individuals of all ages and ethnic backgrounds, but it has been observed more frequently in individuals of African, East Asian, and Asian descent. [7]
