The goal of endodontic treatment is to provide a hermetic seal, which aids in the elimination of disease causing microorganisms. However, a procedural error during treatment may jeopardize the outcome. The case report presented here is on the management of the ‘Spaghetti phenomenon’ which is the result of gross overfilling of the root canal. Retrieval of the material which had extruded beyond the apex in this case was impossible in the orthograde manner, which is why surgical intervention had to be undertaken. Visualization of the extent of the lesion was greatly enhanced by the use of advanced diagnostic techniques such as Cone Beam Computed Tomography.
