A 12-year-old boy presented with a fractured sewing needle within the palatal root canal of a nonvital permanent maxillary first molar. The patient admitted that he had often placed a sewing needle in the tooth to relieve discomfort associated with it. A minimal amount of tooth structure was removed around the foreign object to facilitate access for K-type files. Under copious irrigation, the files were worked around the object to loosen it. The fractured needle was removed with a tweezers that had long, narrow beaks. Use of this simple technique allowed the object to be removed from the root canal with minimal damage to internal tooth structure.
一名12岁男孩的上颌第一恒磨牙腭侧根管内有一根折断的缝纫针。患者承认他经常将缝纫针放入牙齿以缓解相关不适。在异物周围去除少量牙体组织，以便于K型锉进入。在大量冲洗下，用锉围绕异物操作以使其松动。用一把喙长而窄的镊子取出折断的针。使用这种简单技术可使异物从根管中取出，同时对牙齿内部结构的损伤最小。
