Management of intrusion depends on several factors such as whether the tooth has a closed or open apex, type of teeth (primary or permanent dentition) and how much the tooth is intruded in mm. This type of dental trauma is complex and is commonly associated with pulpal necrosis and inflammatory ankylosis.
Dental injuries involving the permanent teeth happen to almost 25% of children in school and 30% of adults. The incident varies in different countries as well as within the country itself. Dental traumatic accidents depends on one's activity status and also the surrounding environment factor but these are the main predisposing risk factor ...
The cause of a tooth crack can be by excessive force applied to a healthy tooth or physiologic forces applied to a weakened tooth. The teeth most commonly involved are usually the lower molars, followed by the upper premolars and molars. The condition is extremely common in the age range of 30–60 years. [2]
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.
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.
If the tooth has not been placed in a suitable storage medium, the dentist will do this first. A thorough extra-oral and intra-oral examination should be performed. The clinician should consider the age of the patient, the history of the injury, status of tooth root apex and whether it is in line with clinical findings. It is advisable to check ...
In young children many cases of dilaceration occur due to some kind of trauma to the tooth, commonly causing dislocation of the tooth affecting its direction and growth. [10] Once a trauma has occurred dilaceration can be prevented by yearly visits to the dentist and maintaining radiographic images to note any changes that may occur.
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).
