Root canal retreatment with post and instrument fragment removal under a microscope

Complaints:

Mobility of a previously placed crown and food impaction between the teeth.

Diagnosis:

Chronic apical periodontitis of tooth 2.6.

Treatment:

Before treatment, professional dental cleaning, a CBCT scan, and a periapical X-ray were performed. Endodontic treatment was carried out under STA computer-assisted anesthesia with rubber dam isolation and microscope control using Seiler Evolution XR6. During the procedure, the old crown, a post, and a fractured instrument fragment were removed, along with old restorations and residual filling material. After root canal retreatment, mechanical and chemical preparation was performed using NiC and SOCO instruments, followed by ultrasonic-activated irrigation and hermetic obturation with warm gutta-percha. Following a control radiographic examination, the tooth was restored with Estelite Asteria composite material and prepared for further prosthetic treatment.
