Preeruptive Intracoronal Radiolucencies: Detection and Nine Years Monitoring with a Series of Dental Radiographs

Figure 6

Sagittal slices of the PEIR-affected tooth (permanent mandibular left second molar) reconstructed from the second CBCT when the patient was 14 years, 9 months old. The PEIR location was reconfirmed to be just under the dentino-enamel junction and not connected to the pulp chamber or oral environment. The distance between the midfloor of the lesion and the pulpal area is 2.00 mm. The PEIR dimension is 2.30 mm occluso-gingival depth, 4.00 mm bucco-lingual width, and 3.40 mm mesio-distal length.
