Frequency of intrusive dislocation in primary teeth and its effects

Abstract

Introduction: The intrusive dislocation in primary teeth is when the tooth moves to the interior of the alveolar bone, and can harm the periodontal structure, the pulp tissue and the successor teeth through the destruction and rupture of the fibers of the periodontal ligament and the vascular supply. Objective: the objective of this study is, through a literature review, to analyze aspects related to intrusive dislocation such as epidemiological data, diagnosis, degrees of injury, radiographic examinations, sequelae in permanent teeth and forms of treatment. Literature review: Intrusive dislocation in children is the trauma that happens most frequently, knowledge of the techniques of manipulation of intrusive dislocation is essential to perform a good treatment. The importance of radiographic examination should be emphasized, because without it it is not possible to find out where the root of the tooth has moved. Most of the time as a form of treatment if the root of the intruded tooth has not reached the successor tooth is chosen to wait for the reeruption of the intruded tooth, but if there is any complication during the wait can opt for tooth extraction. Final considerations: Most of the time as a form of treatment it is chosen to wait for the reeruption of the primary teeth when there is no compromise of the permanent successor tooth and opt for extraction only if there is any complication during the wait, due to the proximity of the primary tooth with the permanent tooth it is common to have the occurrence of sequelae in the permanents, That is why it is necessary to have a follow-up until the reeruption of the primary tooth and an orientation to the country, it is also important to emphasize the importance of clinical and radiographic examination because when they are done correctly they can reduce the chances of sequelae in the primary and permanent teeth.
