Pulp exposure due to traumatic injuries in the anterior permanent teeth of adolescents is a common occurrence. A vital permanent maxillary incisor with complex crown fracture and pulp exposure was treated by partial pulpotomy and assessed clinically through pulpal sensitivity tests and radiographically for periapical healing. Partial pulpotomy consisted of pulp tissue removal to a depth of only 1 to 2 mm, then capping the pulpal wound with calcium hydroxide, lining with resin-modified glass-ionomer cement, and restoration with resin composite. At each recall (7, 15, 21, 50, 90, 150, and 250 days), no spontaneous pain was observed; the pulp showed signs of vitality and absence of periapical radiolucency after 90 days. For long-term success, partial pulpotomy is recommended as an option for cases of traumatic pulp exposure in permanent incisors with crown fractures.
青少年恒牙前牙因外伤导致牙髓暴露是常见现象。对一颗冠折复杂且牙髓暴露的活髓上颌恒切牙进行了部分活髓切断术，并通过牙髓敏感性测试进行临床评估，同时进行根尖周愈合的影像学评估。部分活髓切断术包括仅去除1至2毫米深度的牙髓组织，然后用氢氧化钙覆盖牙髓创面，用树脂改性玻璃离子水门汀衬层，并用树脂复合材料修复。在每次复诊时（7、15、21、50、90、150和250天），均未观察到自发痛；90天后牙髓显示有活力迹象且根尖周无透射影。为获得长期成功，对于冠折的恒牙外伤牙髓暴露病例，建议将部分活髓切断术作为一种治疗选择。
