Dental trauma to the permanent dentition can lead to clinical complications and its management may considerably challenge a practitioner. The incidence of pulp canal obliteration following dental trauma has been reported to be approximately 4 - 24%. Attempting to locate canals following calcific metamorphosis and negotiating it to full working length may lead to iatrogenic errors such as fractured instrument and perforation. This review article describes the possible etiology of Calcific Metamorphosis, its clinical and radiographic features as well as its management.
恒牙牙外伤可导致临床并发症,其治疗可能会给从业者带来很大挑战。据报道,牙外伤后牙髓腔闭锁的发生率约为4%-24%。试图在钙化性变形后定位根管并将其疏通至全长可能会导致医源性失误,如器械折断和穿孔。这篇综述文章描述了钙化性变形的可能病因、临床和影像学特征及其治疗方法。
