Dental trauma is a major global health issue and it affects 17.5% of children and adolescents. [9] It is most commonly seen in school children. Dental subluxation is one of the most common traumatic injuries in primary dentition. Maxillary central incisors are the most commonly affected teeth.
Dental subluxation is a non-dental-urgency condition, i.e., unlikely to result in significant morbidity if not seen within 24 hours by a dentist, [10] and usually treated conservatively: good oral hygiene with 0.12% chlorhexidine gluconate mouthwash, a soft and cold diet, and avoidance of smoking for several days.

When the injured teeth are painful while functioning due to damage to the periodontal ligaments (e.g., dental subluxation), a temporary splinting of the injured teeth may relieve the pain and enhance eating ability. [34] Splinting should only be used in certain situations.
The fulcrum is usually the crest of the socket bone; however, adjacent teeth can be used if they are also to be extracted. The contact point on the tooth or root surface where force is delivered is described as the purchase point, and the position of this can be idealised by cutting bone or sectioning teeth. With root picks especially, a slot ...
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.
A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet. [1] A partial dislocation is referred to as a subluxation . Dislocations are commonly caused by sudden trauma to the joint like during a car accident or fall.
The material is also more technique-forgiving compared to composite restorations used for that purpose. Dental amalgam is also radiopaque which is beneficial for differentiating the material between tooth tissues on radiographs for diagnosing secondary caries. The cost of the restoration is typically cheaper than composite restorations.
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.
