Maxillary premolars exhibit variable root canal morphology, but it is quite rare to find three canals in their root system. The aim of this case report is to present the diagnosis and clinical management of a patient with anatomical variation of having three root canals in the maxillary first premolar. Three-canalled maxillary premolars are quite an endodontic challenge. A discussion is provided here to facilitate the early recognition of these canals, access cavity modifications for better intra-canal preparation and obturation procedures. Clinicians are required to be aware of the anatomical variations they may encounter when dealing with maxillary premolars and should be trained to apply this knowledge in the clinical scenario.
上颌前磨牙呈现出多样的根管形态,但在其根系中发现三根根管的情况相当罕见。本病例报告的目的是展示一例上颌第一前磨牙存在三根根管这一解剖变异患者的诊断和临床处理。具有三根根管的上颌前磨牙对牙髓治疗而言是一项颇具挑战的任务。本文进行了讨论,以促进对这些根管的早期识别、为更好地进行根管预备和充填程序而对上颌洞形进行的改良。临床医生在处理上颌前磨牙时需要意识到可能遇到的解剖变异,并且应该接受培训以便在临床场景中应用这一知识。
