Figure 1. Radiolucency suggestive of a fracture line in the furcation area of a root-filled mandibular first molar.
Figure 2. Fracture of the mandibular first molar extending along the margins of the intracoronal restoration.
Figure 3. The fracture extending subgingivally on the buccal surface.
Figure 4. Detection of an 8-mm periodontal defect in the region of the fracture.
Figure 5. Following extraction, an incomplete vertical fracture of the tooth extending from the crown on to the distal surface of the mesial root was evident.
