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. [10] [11] Some studies have proposed that the resilience nature of periodontium favours dislocation than fracture of the tooth itself. [12]
In healthy teeth, the periodontal ligament (PDL) fibroblasts block osteogenic cells within the periodontium by releasing locally acting regulators. This separates the tooth root from alveolar bone. [12] Damage to the PDL disrupts this process resulting bone growth across the periodontal space and fusion with the root.
The management depends on the type of injury involved and whether it is a baby or an adult tooth. If teeth are completely knocked out baby front teeth should not be replaced. The area should be cleaned gently and the child brought to see a dentist. Adult front teeth (which usually erupt at around six years of age) can be replaced immediately if ...
Each joint in the body can be dislocated, however, there are common sites where most dislocations occur. The most common dislocated parts of the body are discussed as follows: Dislocated shoulder. Anterior shoulder dislocation is the most common type of shoulder dislocation, accounting for at least 90% of shoulder dislocations.
This is the procedure of increasing resistance of tooth to an applied force by fixing it to a neighbouring tooth or teeth. Splinting should only be done when other aetiologies are addressed, such as periodontal disease or traumatic occlusion, or when treatments are difficult due to the lack of tooth stabilization.
ART fillings can be used in multiple situations, such as for single-surface cavities in primary (baby teeth) and permanent (adult) teeth, and multiple-surface cavities in primary teeth, if no other option is available or suitable (e.g. Hall Technique). They can also be used for non-frankly cavitated lesions (presenting a shadow under the enamel ...
During this process, the tooth root cells become necrotic (dead) and will activate the immunologic mechanism of the body to attempt to remove this necrotic layer and literally eats away the tooth root. This is called "root resorption". It is a slow, but non-painful, process that is sometimes not observed by x-rays for years. Once this process ...
There are numerous types of precision attachments (also known as combined restorations) to aid removable prosthetic attachment to teeth, including magnets, clips, hooks, and implants which may themselves be seen as a form of dental restoration. The CEREC method is a chairside CAD/CAM restorative procedure. An optical impression of the prepared ...
