The storage conditions of the avulsed tooth; The duration of time the tooth was out of its socket prior to replantation [30] [31] [32] Additionally, the choice of treatment is closely related to the maturity of the root (open or closed apex) and the condition of the PDL cells, which is dependent on the time out of the mouth and the storage ...
Trauma to primary teeth occurs most commonly at the age of two to three years, during the development of motor coordination. [7] When primary teeth are injured, the resulting treatment prioritises the safety of the adult tooth, [7] and should avoid any risk of damaging the permanent successors. [8]
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.
Other terms used to describe regression in children with autism are autism with regression, autistic regression, setback-type autism, and acquired autistic syndrome. [16] Within the regressive autism developmental course, there are two patterns. The first pattern is when developmental losses occur in the first 15 months to 3 years.
The exact causes of pulp obliteration are unclear [2] but it typically occurs in response to dental trauma, [1] especially following luxation injuries involving displacement, particularly if a tooth is replanted after being completely avulsed (knocked out) [3] This response is common in this scenario and typically starts to occur several months ...
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.
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).
