Microendodontic. Calcified canals. Case Study Number 506846
Patient referred for endodontic treatment on this mandibular first molar. Coronal-radicular access was already done but canal entries are embedded in a mass of calcified dentine and could not be found.
Preoperative X ray dental film shows a complete mineralization of both mesial and distal canals coronal third. This is an intricate root canal procedure, because this pre operative condition involves dealing with complete canal stenosis caused by dystrophic calcifications.
Dental operative microscope (Opmi Proergo from Carl Zeiss) and ultrasonic tips where most helpful in locating both mesial and distal canal entries.
Once located, our first instrument in four canals were K files number 06 (second X ray dental film). Then, mesial and distal canals have been shaped and cleaned with the Pro Taper system (Maillefer) and lots of RC PrepTM. They were subsequently filled with gutta percha (lateral and vertical condensation) and Pulp Canal Sealer EWT TM
Third X ray dental film (Clark’s rule) shows all four treated canals.
Amalgam corono apical core build up is shown in last post operative X ray dental film. A crown is planned by patient regular dentist.
