case_images: 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).
case_images: Transoperative images. (a) Caldwell-Luc access. (b) Third molar with calcified mass associated with the roots.

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