If a tooth is avulsed, make sure it is a permanent tooth (primary teeth should not be replanted, and instead the injury site should be cleaned to allow the adult tooth to begin to erupt). Reassure the patient and keep them calm. If the tooth can be found, pick it up by the crown (the white part). Avoid touching the root part.
If apex of tooth is displaced towards the palate and making contact with the tooth germ then tooth is extracted Intrusive Luxation: Displacement of tooth into the alveolar bone (pushed into the socket) causing fracture of the alveolar bone. It is the most damaging injury to the tooth and supporting tissues as ankylosis and pulp necrosis can occur.
Resorption of the root of the tooth, or root resorption, is the progressive loss of dentin and cementum by the action of odontoclasts. [4] Root resorption is a normal physiological process that occurs in the exfoliation of the primary dentition.
Regressive autism occurs when a child appears to develop typically but then starts to lose speech and social skills and is subsequently diagnosed with ASD. [15] Other terms used to describe regression in children with autism are autism with regression , autistic regression , setback-type autism , and acquired autistic syndrome .
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 ...
Teeth may become impacted because of adjacent teeth, dense overlying bone, excessive soft tissue or a genetic abnormality. Most often, the cause of impaction is inadequate arch length and space in which to erupt. That is the total length of the alveolar arch is smaller than the tooth arch (the combined mesiodistal width of each tooth).
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder "characterized by persistent deficits in social communication and social interaction across multiple contexts" and "restricted, repetitive patterns of behavior, interests, or activities". [11] Sensory abnormalities are also included in the diagnostic manuals ...
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.
