Conventionally, few-days-old pulp exposures have been treated with root canal treatment. We report four cases of traumatized, fully matured, maxillary permanent central incisors, which have been treated by Biodentine pulpotomy several days after traumatic pulp exposure. Biodentine pulpotomy consisted of pulp tissue removal to a depth of 2 mm, then capping the pulpal wound with Biodentine, followed by immediate restoration. The teeth were assessed clinically through pulpal sensitivity tests and radiographically for periapical healing. At each recall (24 hours, 1 week, 30 days, 3, 6, 12, and 18 months), no spontaneous pain was observed; the pulp showed signs of vitality and absence of periapical radiolucency after 18 months. Biodentine pulpotomy is recommended as a treatment option for cases of vital pulp exposure in permanent incisors due to trauma.
传统上，对于受伤几天的牙髓暴露，一直采用根管治疗。我们报告了4例受创伤的、完全成熟的上颌恒中切牙病例，这些牙齿在创伤性牙髓暴露几天后接受了生物陶瓷牙髓切断术治疗。生物陶瓷牙髓切断术包括将牙髓组织切除至2毫米深度，然后用生物陶瓷覆盖牙髓创口，随后立即进行修复。通过牙髓敏感性测试对牙齿进行临床评估，并通过影像学检查根尖愈合情况。在每次复诊时（24小时、1周、30天、3、6、12和18个月），均未观察到自发痛；18个月后，牙髓显示出活力迹象且根尖无透射区。对于因外伤导致恒牙切牙髓暴露的病例，推荐采用生物陶瓷牙髓切断术作为一种治疗选择。
