Root Canals

Root Canals

Root canals on teeth 25 and 26 (upper left second premolar and first molar), done because of obvious pulpal decay (decay into the nerve) on both teeth. In these cases, there are only two appropriate options: extraction of teeth, or root canals to preserve them. This patient opted to save both teeth by having root canals done on both teeth. Later, he would go on to have crowns on both teeth to prevent fractures of the teeth.

Teeth: 25 and 26

25 – 1 canal, symptomatic irreversible pulpitis, normal apical tissues

26 – 4 canals, symptomatic irreversible pulpitis, normal apical tissues

Condition of teeth on access: hyperemic

Final canal instrumentation:

25: WL = 24mm instrumented to 35/0.04

26: MB1: 19mm to 35/0.04 MB2: 19mm to 35/0.04 DB: 19mm to 35/0.04 P: 22mm to #40 SS file

Both teeth irrigated with NaOCl(aq) and 17% EDTA (aq) with Piezoelectric ultrasonic activation, obturated with gutta percha and Kerr RCS via System B downpack and Obtura backfill. Final fillings were completed with Air abrasion/phosphoric acid etch/Kerr Optibond FL/Ultradent Permaflo Purple on orifices/Dentsply Esthet-X flowable A1/Esthet-X A3. Treatment complete under Global Surgical Operating Microscope.
