There is widespread knowledge that the mental foramen or incisive foramen can be projected onto tooth roots in conventional radiographs, thus simulating apical lesions. In contrast, the anatomical structure of the canalis sinuosus and its branching canals in the anterior maxilla are less known. Sometimes these bone canals mimic a dentino- or osteolysis on conventional radiographs. If these bone canals project onto the roots of the anterior maxillary teeth, there is a risk of misinterpretation as root resorption or apical periodontitis. This case report presents an incidental radiological finding. Due to a radiolucency within the root of tooth 11, root resorption was suspected. Using cone beam-computed tomography, the origin of this radiolucency was clearly identified as an anatomical structure, and the suspected diagnosis was ruled out. This case highlights the importance of the knowledge of anatomical structures to avoid misinterpretations and unnecessary treatments.
