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 of 75-85% oxygen saturation and a negative response below 75%, indicating pulp necrosis.
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.
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.
When at least 3 teeth are affected, it is referred to as multiple idiopathic cervical root resorption. The causes of external cervical root resorption are poorly understood but trauma, periodontal treatment, and/or tooth whitening may be predisposing factors. [16]
Dental cysts are usually caused due to root infection involving tooth decay. Untreated dental caries then allow bacteria to reach the level of the pulp, causing infection. The bacteria gains access to the periapical region of the tooth through deeper infection of the pulp, traveling through the roots.

Teeth that have multiple traumatic events also showed to have higher chance of pulp necrosis (61.9%) compared to teeth that experienced a single traumatic injury (25.3%) in the studies (1) [41] Image shows a grey discoloured upper right front incisor, usually indicating that the tooth is non-vital
