A Rare Case of Impacted and Inverted Primary Incisor Tooth “A Case of Developmental Anomaly”

Introduction: Children generally suffer from dental traumas to their primary teeth. Traumas may lead to complications, depending on the site and potency of the injuries. The acute dental abscess usually occurs secondary to dental caries or dental trauma. The necrotic pulp tissue becomes colonized by a specialized mixed anaerobic biofilm. Case Presentation: A 5-year-old boy referred to clinic (Gaziosmanpasa University, Department of Pediatric Dentistry), with a complaint of acute dental abscess. His mother reported a history of dental injury to upper anterior region at the age of 4-6 months and the boy was not seen by dentist following the trauma. Clinical examination revealed unerupted or missing left primary central tooth. There was pain, swelling and erythema localized to the affected region. Radiographic examination revealed that the left primary tooth was impacted and inverted. Treatment consisted of extraction of the impacted and inverted tooth. Parents were informed about the procedure and written informed consent was taken. The impacted and inverted tooth was extracted under local anesthesia . The patient was recalled for a control visit 6 months later but he came back clinic 2 years later. Postoperative recovery was uneventful and erupted permanent maxillary central tooth had normal morphology. Conclusion: In the present case, the malpositioning of the tooth germ may have been the cause of invertion and impaction. In our opinion, previous trauma could have been the cause of malpositioning of the tooth germ. Parents should be aware of characteristic of primary dentition period and effects of dental injuries. Long-term follow should be planned for traumatized children in primary and permanent dentition period.
