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

Figure 3

Sagittal slices of the PEIR-affected tooth (permanent mandibular left second molar) reconstructed from the first CBCT when the patient was 11 years, 5 months old. PEIR presented as an obvious radiolucency within the dentin with no direct exposure of the lesion or dentin to the oral cavity. The distance from the midfloor of the lesion to the roof of the pulpal area was 1.58 mm. The PEIR dimension is 3.75 mm occluso-gingival depth, 5.52 mm bucco-lingual width, and 3.05 mm mesio-distal length.
