Bayonet Root Form

Clinician: Stephen P. Boger, DDS  Minnetonka, MN

Description of the tooth: Tooth #13 with bayonet root form and associated S-curve canal.

Diagnosis: Acute pulpal necrosis

The Situation: A 38-year old female patient presented with acute pain of two-day duration on her upper left side. Clinical and radiographic examination revealed the #13 was the probable cause of her discomfort, and endodontic therapy was recommended. The patient was advised that the tooth had a challenging shape to its root, but Dr. Boger was optimistic about a successful result.

The Procedure: The patient was anesthetized with two carpules of Septocaine and the tooth was isolated with a rubber dam. Access was obtained using a #555 carbide bur and a #8 long shank round bur. After access was obtained, Dr. Boger used ProTaper SX to create straight line access, followed by a #10 K-file to confirm patency and establish working length.

PathFile files 13/16/19 were then used in sequence to establish glide path. Final preparation of the canal was achieved with a small WaveOne Reciprocating File, in conjunction with sodium hypochlorite irrigation.

Obturation was completed with a size #20 GuttaCore Crosslinked Gutta-Percha Core Obturator and ThermaSeal Plus Ribbon root canal sealer. This procedure was completed in one appointment.
