Pulp necrosis as a result of trauma is common in almost all intruded teeth, and the ideal treatment method for intruded immature and necrotic teeth has not yet been determined. Therefore, the aim of this report was to present a case of pulp revascularisation in a severely intruded immature maxillary right incisor.
After clinical and radiographic examination, the incisor was defined as necrotic. Revascularisation therapy was performed over multiple appointments. After 21 months of recall appointments, healing of the periapical area and apical closure were seen to be complete. However, at the 27-month appointment, the vitality tests were negative and revascularisation of the right incisor, which had intrusion injuries, had not occurred. The tooth underwent root canal treatment. Finally, the tooth spontaneously erupted into the vestibule and was repositioned with orthodontic appliances.
Although revascularisation can promote continued root development and root dentin apposition, long-term root canal treatment may be required due to treatment results with periapical inflammation in intruded teeth with open apices.
创伤导致的牙髓坏死在几乎所有嵌入性牙齿中都很常见,对于嵌入性未成熟坏死牙齿的理想治疗方法尚未确定。因此,本报告的目的是介绍一例严重嵌入性未成熟上颌右切牙牙髓血管再生的病例。
经过临床和影像学检查,该切牙被确定为坏死。多次就诊进行了血管再生治疗。在21个月的复诊后,根尖周区域愈合且根尖闭合完成。然而,在27个月复诊时,活力测试呈阴性,有嵌入伤的右切牙未发生血管再生。该牙齿接受了根管治疗。最后,牙齿自发萌出至前庭,并通过正畸矫治器重新定位。
尽管血管再生可促进牙根的持续发育和牙根牙本质的沉积,但由于根尖开放的嵌入性牙齿根尖周炎症的治疗结果,可能需要进行长期根管治疗。
