Cone-beam computed tomography (CBCT) provides images without overlapping anatomical structures, which is important for the diagnosis and assessment of florid cemento-osseous dysplasia. This fibro-osseous lesion that affects the alveolar process without compromising the teeth’ pulp vitality is usually asymptomatic, and bone expansion, cortical disruption, and root resorption are uncommon. Due to its avascular characteristic, surgical procedures are often contraindicated. In this case, a 59-year-old female patient presented with a complaint of pain in the right maxillary central incisor. Panoramic and periapical radiographs showed florid cemento-osseous dysplasia in some regions. The right maxillary central incisor showed an extensive radiolucent image suggestive of root resorption but without fibro- -osseous lesion. For better evaluation and implant planning, CBCT was performed and demonstrated florid cemento-osseous dysplasia adjacent to the right maxillary central incisor, contraindicating implant placement. In other regions, CBCT enabled the identification of the expansive features of this fibro-osseous lesion.
