Sinus tracts are a consequence of chronic apical disease or vertical root fractures. They are usually diagnosed upon routine clinical examination or in response to patient complaints of swelling and occasional pus secretion. An unusual case report of a maxillary canine with multiple orifices of sinus tracts is presented. Vertical root fracture was confirmed after removal of the root canal filling under an operating microscope. Clinicians should suspect vertical root fracture when multiple sinus tracts originating from the same tooth are observed. Schlagwörter: multiple, sinus tract, tracing, vertical root fracture
