Abstract

Periapical cemento-osseous dysplasia (PCOD) is a subtype of cemento-osseous dysplasia that usually occurs in middle-aged black women. This report described a case of a 45-year-old Iranian woman who was diagnosed with PCOD on the basis of cone beam computed tomographic (CBCT) findings. CBCT enabled detailed visualization of the bone changes. This report described the special radiographic characteristics of PCOD, including discontinuity of the lingual cortex on the CBCT sectional and three-dimensional images.

Figure

• 

  Fig. 1 A reformatted panoramic CBCT image shows a multifocal lesion extending from the mesial side of the right mandibular lateral incisor to the distal side of the left mandibular lateral incisor.

• 

  Fig. 2 A. An axial CBCT image shows the expansion of the buccal cortex (white arrows) and discontinuity of the lingual cortex (red arrow). B. Another axial CBCT image shows the same features as A. C. Cross-sectional CBCT images show the discontinuity of the lingual cortical plate.

• 

  Fig. 3 Three-dimensional reconstructed CBCT images of the mandible. A. The frontal view shows erosion of the buccal cortex of the lesion. B. The lingual view shows that the lesion erodes the lingual cortex.

• 

  Fig. 4 A periapical radiograph shows a mixed radiolucent-radiopaque appearance of the lesion, located on the apices of the lower incisors. The lamina dura surrounding the apical areas of the involved teeth is lost.
