Initial radiograph of the first molar. Observe the extravasation of the filling material in the mesial root (a). Clinical aspect of the mesial root showing the vertical root fracture and bone fenestration (b). Application of dye (SableSeek, Ultradent) confirming the presence of RVF (c). Radiograph aspect after immediate implant placement (Neodent, 10.0 x 4.3) (d). Radiograph aspect 4 months after the immediate implant installation with the placement of temporary crown (e).

The periapical radiographs (Figure 1(a)) indicated overfilling. A full-thickness gingival flap preserving the gingival margin for endodontic access was performed after initial curettage was possible to visualize the vertical root fracture (Figure 1(b)). Through a dye Sable Seek (Ultradent, South Jordan, Utah 84095, USA) was confirmed fracture (Figure 1(c)). At the same time of surgery, the extraction and immediate postextraction implant placement was performed (Figure 1(d)). AG, Wolhusen, Switzerland). After a healing period of about 4 months, a screw-type implant-supported provisional restoration was placed, and the implant started occlusal loading (Figure 1(e)).

Initial clinical aspect. Note the fracture in vestibular region below the end of restoration (a). Radiograph aspect with diffuse radiolucent image (b). Clinical aspect after removal of restoration (c). Application of dye (SableSeek, Ultradent) confirming the presence of RVF (d). Radiographic image after installation of the immediate implant (Neodent, 10.0 x 4.3) (e). Radiograph aspect 4 months after immediate implant installation (f).

Vasconcellos, Sao Paulo, SP, Brazil), was shown a crack at the crown on the labial surface without the presence of periodontal pockets (Figure 2(a)). Vitality tests on tooth (thermal hot and cold) were negative and vertical percussion pain was present. Radiographic examination showed a diffuse, radiolucent periapical image. (Figure 2(b)). The restoration was removed enabling the visualization of the crack toward the pulp chamber (Figure 2(c)). With use of dye SableSeek, it was possible to visualize the fracture in buccal-lingual direction (Figure 2(d)), indicating the tooth for extraction with immediate implant installation performed in the same time (Figure 2(e)). After a healing period of about 4 months, a screw-type implant-supported provisional restoration was placed, and the implant started occlusal loading (Figure 2(f)).
