On clinical examination, the mandibular first molar exhibited caries on the distoocclusal aspect and second molar exhibited abnormal crown morphology with 2 large extra cusps on the buccal aspect of the tooth (Figure 1(a)). On radiographic examination, tooth 21 showed resorption with the distal root and the exact anatomy of tooth 20 that could not be clearly identified, but it was possible to recognize the complex structure of the pulp (Figure 1(b)).

The involved tooth was focused and the morphology was obtained in transverse, axial, and sagittal sections of 0.5 mm thickness (Figure 2).
