Reabsorção radicular externa em dente decíduo: relato de caso clínico

Abstract

Trauma in the primary dentition presents high prevalence and has as a consequence a very common sequel called external root resorption. External root resorption triggered by trauma affects the root of the tooth, compromising its entire structure, causing the clastic cells to function disorderly, therefore promoting the elimination of minerals from the injured tooth. External root resorption can compromise anatomical, functional, and aesthetic factors that are essential for maintaining oral health and deciduous teeth; it can compromise the formation of the permanent tooth, which can cause discoloration or hypoplasia of enamel and disturbances of the eruption of the permanent tooth. The present study aims to present a literature review on external resorption and to report a clinical case. The male patient came to the Centro Universitário UDF dental clinic complaining of pain in tooth 54. During the anamnesis, it was observed that tooth 51 was darkened. After periapical radiography, the rootlesion was diagnosed with external resorption. The treatment plan determined tooth extraction due to the possibility of the deciduous tooth cause impairment in the formation of the permanent tooth successor. Thus, the importance of early diagnosis of external root resorption in primary teeth is emphasized as a way to prevent possible problems in permanent dentition.
