Managing Cracked Teeth with Root Extension: A Prospective Preliminary Study Using Biodentine™ Material

Figure 3

Initial digital radiography of tooth #18 shows asymptomatic apical periodontitis (A); the presence of buccal sinus tract localized in the one-third cervical of the tooth was noted (B); clinical and radiographic tracking of the sinus tract led to the cervical region via a distal approach (C, D); resin was removed, and CLs were assessed under the dental operating microscope in the distal marginal ridge extending 2.0 mm into the canal (white arrow) (E, F); endodontic treatment was performed, and Biodentine™ intraorifice barrier was placed 2.0 mm deepest the CL (white arrow); the coronary access was filled with resin for subsequent construction of a full-coverage crown bonded fixed (G, H).
