Radiopaque Lesion at Tooth #30 Suggestive of Cemento-Osseous Dysplasia

A 56-year-old female presented as a new, asymptomatic patient to the referring general dentist, who noted a radiopaque lesion on tooth #30 without clear delineation of the PDL space and with inconclusive thermal vitality testing. The referring doctor suspected idiopathic osteosclerosis, osseous dysplasia, or cementoblastoma. The radiologist noted irregularly shaped high-density entities fused to the roots of #30, surrounded by lower-density areas with a faint granular appearance that thinned the adjacent cortices and produced punctate perforations.

The findings were suggestive of cemento-osseous dysplasia, with cementoblastoma less likely given the radiographic features and the lack of clinical symptoms. Clinical correlation with follow-up was recommended to rule out cementoblastoma. The radiologist noted that recognizing these nuances between conditions can help avoid unnecessary biopsy or intervention.
