A computed tomographic (CT) was requested and showed a well-defined hyperdense mass showing a hypodense center inside the left maxillary sinus measuring approximately 15 mm x 10 mm situated in a posterior position of this anatomical space (Figure 1).
Transoperative images. (a) Caldwell-Luc access. (b) Third molar with calcified mass associated with the roots.

Once the sinus membrane was exposed, it was carefully detached from the bone without it disrupting until the calcified mass was reached (Figure 2).
Histologic examination. (a) Cementum-like mineralized tissue (HE - 100x). (b) Numerous and voluminous cementoblastomas (HE - 400x).
