Tooth extraction was contraindicated because of the risk of medication-related osteonecrosis of the jaw (MRONJ).
A corono-radicular crack was detected along the distal wall of the crown extending apically into the distolingual root. The crack appeared to terminate at the middle third of the distolingual root.
Immediate Post Endodontic Dentin Sealing (IPDS):
- Clearfil AP-X composite for post endodontic dentin sealing
- EverX Flow in the access cavity to reinforce structurally the tooth and to limit crack propagation. The embedded fibers can bridge and deflect cracks, thereby preventing their further extension.

- Filtek One Bulk Fill Universal composite for occlusal sealing.
Endodontic treatment was carried out using a minimally invasive approach, including conservative canal preparation with low-taper rotary instruments (3–4%), three-dimensional erbium:YAG laser–assisted disinfection, and obturation with a calcium silicate–based sealer. The tooth was left in slight infraocclusion, and circumferential cuspal coverage was subsequently provided by the patient’s referring dentist.
