case_images: Also, a 10 mm deep periodontal pocket was observed, and after a tracking test in the gingival fistula (Figure 1), we opted for an exploring surgery to detect the origin of the pus.

case_images: A full-thickness flap was elevated and a granulation tissue was observed at the root buccal surface; also, a total absence of the alveolar bone was observed in this area all through the tooth length except for 3 mm of the radicular apex (Figure 2A). After removing the inflammatory tissues, it was possible to verify the presence of a VRF in the buccal surface of the tooth (Figure 2B). A schematic drawn shows the fracture in detail (Figure 2C).

case_images: After adhesive polymerization, we filled the cavity with composite resin Tetric Ceran (Ivoclar, Schaan, Liechtenstein), followed by light curing for 40 seconds (Figure 3A and Figure 3B). In order to accelerate tissue repair, minimize possible gingival recession and an anti-inflammatory response after the surgery, 5 sections of low power laser with a wavelength of 685 nm (Photon Lase, DMC, Sa~o Carlos, Brazil) was performed around the tooth with occasional applications at mesial, distal, apical and cervical with intervals of 48 hours between sessions (Figure 3C).
