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.
与经牙髓治疗的牙齿相关的垂直根折,较少见于活髓牙,是最难诊断和治疗的临床问题之一。由于没有特定症状,诊断可能会很困难。牙髓病医生对这种情况的临床检测越来越频繁,而全科医生对此往往估计不足。因为垂直根折几乎只累及经牙髓治疗的牙齿,所以常常难以将患有这种情况的牙齿与牙髓治疗失败的牙齿或伴有牙周病变的牙齿区分开来。此外,尽管在各种研究中尝试修复折断的牙根,成功率各不相同,但诊断为垂直根折的牙齿通常还是会被拔除。早期发现牙根折断并拔除患牙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在这方面已被证明非常准确。本文重点介绍诊断和治疗策略,并讨论可能有助于预防垂直根折的诱发因素。
