To report the diagnosis and successful clinical management of a patient with anatomical variation in maxillary first and second premolars.
Maxillary premolars have a highly variable root canal morphology, but it is rare, especially in the second premolar, to find three canals. This article describes the diagnosis and clinical management of first and second premolars with three canals and three separate roots, drawing particular attention to radiographic interpretation and access refinements.
Clinicians should be aware of anatomical variations in maxillary premolars and be able to apply this knowledge in radiographic and clinical interpretation. Access cavity refinements may be required for stress-free entry to complex anatomy. Complex premolar anatomy may be predictably managed following its identification and negotiation.
报告一例上颌第一和第二前磨牙解剖变异患者的诊断及成功的临床处理。
上颌前磨牙根管形态高度多变，但发现三根根管的情况较为罕见，尤其是在第二前磨牙。本文描述了具有三根根管和三个独立牙根的第一和第二前磨牙的诊断及临床处理，特别关注影像学解读和开髓洞形的优化。
临床医生应了解上颌前磨牙的解剖变异，并能够将此知识应用于影像学和临床解读。为无压力进入复杂解剖结构，可能需要优化开髓洞形。复杂的前磨牙解剖结构在识别和疏通后可得到可预测的处理。
