A study was done to assess the accuracy of pulse oximetry in comparison to thermal and electrical tests. Customized pulse oximeter dental probes were placed on the crown of the tooth, with oxygen saturation values recorded after 30 seconds of monitoring each tooth. The values were taken as a positive response (i.e. vital pulp) within the range ...
Dental avulsion is a type of dental trauma, and the prevalence of dental trauma is estimated at 17.5% and varies with geographical area. [36] Although dental trauma is relatively low, dental avulsion is the fourth most prevalent type of dental trauma. [37] Dental avulsion is more prevalent in males than females.
When teeth are damaged or injured in any way, as internal bleeding occurs in the pulp chamber, blood gets into the dentinal nerves and gets trapped into the pulp, staining the dentin. Post trauma, a tooth can discolour and turn black or grey within a few days and if the injury is mild the tooth may return to its original status.
Tooth ankylosis refers to a fusion between a tooth and underlying bony support tissues. In some species, this is a normal process that occurs during the formation or maintenance of the dentition. [1] By contrast, in humans tooth ankylosis is pathological, whereby a fusion between alveolar bone and the cementum of a tooth occurs.
Trauma is the most common cause of loss of permanent incisors in childhood. Dental trauma often leads to complications such as pulpal necrosis, and it is nearly impossible to predict the long-term prognosis of the injured tooth; the injury often results in long-term restorative problems.

After having patients describe in painful detail what caused their moral injury, therapists asked them to choose someone they saw as a compassionate moral authority and hold an imaginary conversation with that person, describing what happened and the shame they feel. They were then asked to verbalize the response, using their imagination.

Occurs due to a localized and limited injury to the root surface or periodontium. It is a transient, self-limiting process of resorption that ceases after removal of the traumatic stimulus and is followed by healing of root surface, cementum, and periodontal ligament. [16]
