Five methods for the treatment of teeth with an incompletely formed apex (open apex) and a necrotic pulp are discussed. The methods discussed include the use of (1) a customized cone (blunt-end, rolled cone); (2) a short-fill technique; (3) periapical surgery (with or without a retrograde seal); (4) apexification (apical closure induction); and (5) one-visit apexification. The apexification techniques, which use various formulations of calcium hydroxide to induce closure, are stressed. Based on the review of the literature and clinical experience of the authors, it was concluded that successful treatment of an immature pulpless tooth can partly result from the antibacterial and calcification-inducing action of calcium hydroxide.
讨论了治疗根尖未完全形成（开放根尖）且牙髓坏死牙齿的五种方法。所讨论的方法包括使用（1）定制的根管糊剂（钝头、卷状糊剂）；（2）短程充填技术；（3）根尖手术（有或无倒充填封闭）；（4）根尖诱导成形术（根尖封闭诱导）；以及（5）一次性根尖诱导成形术。着重介绍了使用各种氢氧化钙制剂诱导根尖封闭的根尖诱导成形技术。根据文献综述和作者的临床经验，得出结论：未成熟无髓牙的成功治疗部分归因于氢氧化钙的抗菌和诱导钙化作用。
