RESUMEN
INTRODUCTION: Bacterial biofilms can be calcified. Granulomas or cystic lesions are the most commonly found entities in endodontics. Surprisingly, this case report presents a rare radiopaque image, in a fan shape, of a calculus-like deposit in the periapical region of the maxillary left central incisor. CASE PRESENTATION: A 34-year-old male, with a history of trauma, presented with apical periodontitis associated with an uncommon image, similar to a calculus-like deposit adhered to the apical region of the maxillary left central incisor. Nonsurgical endodontic intervention was performed, followed by apicoectomy and histopathological analysis of the collected material. The results of the biopsy were not compatible with a cyst or granuloma but showed fibrous connective tissue with calcified areas. DISCUSSION: Correct diagnosis in endodontics is possible with a well-conducted anamnesis, complementary imaging exams and, in some cases, histopathological analysis. The periapical calculus-like deposit, associated with a periapical radiolucent lesion, was a result of the body's fight for healing, producing unusual radiopacity. CONCLUSION: The presence of the calculus-like deposit in a fan shape at the root surface represented dystrophic calcification as a manifestation of the attempt to heal. In the present case, apicoectomy and tissue biopsy for histological evaluation were fundamental for the correct diagnosis.
RESUMEN
Introdução: Alterações morfológicas na cavidade pulpar e na anatomia radicular podem constituir um desafio ao tratamento endodôntico. A dilaceração pode ser resultado de trauma na dentição decídua, na época da formação das raízes, provocando acentuada curvatura da raiz ou da coroa em um dente permanente. Objetivo: O presente relato de caso teve por objetivo descrever o tratamento endodôntico de um dente #41 com acentuada dilaceração radicular. Radiograficamente, a região periapical do dente #41 mostrou extensa área radiolúcida, sugestiva de osteólise periapical em decorrência de necrose pulpar, que foi confirmada pela ausência de resposta aos testes pulpares. O tratamento endodôntico foi realizado. Conclusão: Após 90 meses de acompanhamento, constatou-se ausência de sinais ou sintomas, e o exame radiográfico forneceu evidências de cicatrização óssea periapical (AU).
Introduction: The morphological changes in the pulp cavity and root anatomy can lead to difficulties in carrying out endodontic treatment. Dilaceration can be the result of trauma in primary dentition, in the root formation phase, provoking accentuated root or crown curvature in a permanent tooth. Objective: The present case report aimed to describe the endodontic treatment of tooth 41 with accentuated root laceration. Radiographically, the periapical region of tooth #41 showed an extensive radiolucent area, suggestive of periapical osteolysis due to pulp necrosis, which was confirmed by the lack of response and pulp tests. Endodontic treatment was realized. Conclusion: The follow-up at 90 months showed no signs or symptoms, and the radiographic examination provided evidence of periapical bone healing.
