Orthopantomographic image showing a deep caries cavity in the right mandibular first molar tooth, a radiolucent area in its mesial root, and subperiosteal new bone formation below the lower border of the mandible (a). Orthopantomographic image taken four months after tooth extraction showing the return of normal bone contours (b).

There was also a lamellar appearance on the external cortical surface of the mandible as well as at the lower edge of the mandibular corpus, showing focal new bone formation (Figure 1(a)).
Axial and cross sections in CBCT showing new bone formation and a tunnel-like defect in the vestibule cortical surface of the inflamed bone starting from the apical region of tooth number 46 (a). CBCT image showing decreased cortical bone thickness and the presence of the original cortex within the enlarged portion of the jaw in the postoperative control (b).

Bone deposition at the radiolucent area in the center was observed at the lower edge of the mandible as well as the vestibule surface in this region (Figure 2(a)).

However, no change could be detected at the lower edge of the mandibular corpus on these conventional radiographs (Figure 3).

When the axial and coronal sections were evaluated, in addition to the inflammation in the apical region of this tooth, bone deposition was observed horizontally on the vestibule surface of the mandible (Figure 4).
