牙根纵裂与牙髓治疗的牙齿和不常见的活髓牙代表了最困难的临床问题之一，以诊断和治疗。在尽可能多的没有具体的症状，诊断可能是困难的。牙髓病医生对这种情况的临床检测越来越频繁，而全科医生却低估了这种情况。因为，牙根纵裂几乎完全涉及牙髓治疗的牙齿;通常很难将这种情况的牙齿与牙髓失败的牙齿或伴随牙周受累的牙齿区分开来。此外，诊断为牙根纵裂的牙齿通常会被拔除，尽管在各种研究中已经尝试过重新连接断裂的牙根，成功率各不相同。早期发现牙根断裂并拔除牙齿，可保持牙槽骨的完整性，以便植入种植体。锥形束计算机断层扫描已被证明在这方面是非常准确的。本文重点介绍了牙根纵裂的诊断和治疗策略，并讨论了可能有助于预防牙根纵裂的诱发因素。
Vertical root fractures associated with endodontically treated teeth and less commonly in vital teeth represent one of the most difficult clinical problems to diagnose and treat. In as much as there are no specific symptoms, diagnosis can be difficult. Clinical detection of this condition by endodontists is becoming more frequent, where as it is rather underestimated by the general practitioners. Since, vertical root fractures almost exclusively involve endodontically treated teeth; it often becomes difficult to differentiate a tooth with this condition from an endodontically failed one or one with concomitant periodontal involvement. Also, a tooth diagnosed for vertical root fracture is usually extracted, though attempts to reunite fractured root have been done in various studies with varying success rates. Early detection of a fractured root and extraction of the tooth maintain the integrity of alveolar bone for placement of an implant. Cone beam computed tomography has been shown to be very accurate in this regard. This article focuses on the diagnostic and treatment strategies, and discusses about predisposing factors which can be useful in the prevention of vertical root fractures.
