Pulp neurovascular plexus response as a result of crown-root horizontal fracture and uncomplicated crown fracture in permanent dentition: a case report

Resumo

Dental trauma often have severe and complex injuries to the dentoalveolar system. Objective: To report the treatment of crown-root horizontal fracture and uncomplicated crown fracture in permanent dentition. Case report: Child patient attended the dental trauma service 30 days after the fall. On clinical and imaging examination, an uncomplicated crown fracture in the right central incisor and crown-root fracture in the left central incisor was possible to identify (tooth 11 and tooth 21 respectively). The conventional restorative treatment (tooth 11) and repositioning (tooth 21) were performed. The endodontic treatment was performed at 6 months of follow-up (tooth 11). At the new imaging exam, cement neoformation was evidenced between the fragments of the crow-root fracture (tooth 21). After 24 months of follow-up, there was a decrease in periapical lesion (tooth 11), and maintenance of pulp vitality (tooth 21). Conclusion: There is a possibility of maintaining pulp vitality in crown-root fractures and highlights the importance of follow-up in non-complicated fractures.
