Reimplante tardio de incisivos centrais superiores avulsionados em adolescentes: uma revisão de escopo e relato comparativo de dois casos
Year: 2026
Type: article
Abstract: Background: Dental avulsion is an emergency; its prognosis depends on the dry extraoral time, the storage medium, and the condition of the periodontal tissues. Delayed reimplantation carries a risk of ankylosis and root resorption. Purpose: To describe the evidence regarding the management and outcomes of delayed reimplantation of permanent maxillary central incisors, and to present two clinical cases involving adolescents. Methods: A descriptive study combining a scoping review—reported according to PRISMA-ScR guidelines—with two clinical cases. PubMed, Scopus, Web of Science, and SciELO were searched. A total of 168 records were identified; after removing 32 duplicates and excluding 98 records based on titles and abstracts, 38 full-text articles were evaluated. The cases involved two 14-year-old males whose teeth were reimplanted 48 hours after the trauma. Results: The 12 sources reviewed identify dry extraoral time and storage conditions as key factors for the periodontal prognosis. In Case 1, which involved dry storage, prolonged rigid splinting, and no endodontic treatment, severe root resorption and findings consistent with ankylosis were observed at one-year follow-up. In Case 2, which involved initial dry storage followed by storage in milk, with endodontic treatment performed eight days after reimplantation, the tooth remained functional at one year, although small radiolucencies—suggestive of resorptive lesions—were noted on the root. Conclusion: These cases illustrate different clinical courses following delayed reimplantation. Due to the descriptive nature of this study, it is not possible to attribute the outcomes to specific interventions or to establish the superiority of one protocol over another.
