Avulsão em dentes permanentes : uma revisão de literatura

Abstract

Traumatic dental injuries are very common to occour during childhood, due to exercises and activities typical of this age group in various environments. Among all the traumatic dental injuries, avulsion is the most serious type. It can be defined as the complete exit of the tooth out of its alveolar socket breaking the fibers of the periodontal ligament. The high occurrence is also due to the protection of periodontal tissues of newly erupted permanent teeth. The present study aimed to bring together the main forms of rescue and treatment of avulsed permanent teeth. To carry out the review, a search was made in the PubMed database with the following descriptors: “dental care”, “tooth avulsion”, “dentition, permanent”. According to studies, the best way to treat cases of avulsion is dental reimplantation, which can be immediate at the site of the trauma or later performed on an emergency basis by a dental surgeon, associated with endodontic treatment. The type of treatment depends on factors such as: degree of root development; the time of exposure of the tooth structure to the dry environment; the preservation medium liquid. The prognosis is variable and must be followed up for at least 3 years, in order to rule out the inevitable long-term sequelae, such as root resorption.
