原发性牙根纵裂的诊治策略

Vertical root fracture in non-endodontically treated teeth, also known as spontaneous vertical root fracture (SVRF), is an intractable disease for most dental practitioners. Due to the lack of pathognomonic clinical manifestation and radiographic presentation in the early stage, the diagnosis of SVRF is extremely challenging even for experienced dentists. Even if SVRF is determined to be present, it is hard to make decision between treatment options including root resection, repairing the fractured root or tooth extract. Timing and method of restoration after tooth extraction also need to be considered. The aim of this paper was to discuss early diagnosis, differential diagnosis, the principles of treatments and the specific treatment plans of SVRF in the light of literature review and a 3-years clinical study, to help clinician to discern SVRF and to act as a reference for better clinical diagnosis and treatment.
