Canalis Sinuosus Mimicking Periapical Pathology on, Radiographic Assessment.

The canalis sinuosus (CS) is an anatomical variation whereby the infra-orbital canal sometimes generates a small, lateral branch (canal) close to its midpoint, to allow the passage of the anterior-superior-alveolar (ASA) neurovascular bundle in the anterior maxilla. This article focuses on an incidental finding of this variant, in a 74-year-old Trinidadian female of Afro-Caribbean descent with an endodontic presenting complaint. The canalis sinuosus shadow on conventional radiography resulted in uncertainty as to the offending tooth until a three-dimensional scan was undertaken in this region. This report will discuss the implications of the presence of this canal from radiologic, endodontic, and surgical perspectives.
