Introduction. The failure of primary endodontic treatment is manifested by
various clinical symptoms following endodontic therapy or, more frequently,
by the development of chronic inflammatory process in the apex region without
any subjective symptoms. In case of unfavorable outcome of the primary
endodontic treatment, orthograde endodontic retreatment is the method of
choice for a prolonged therapy. Outline of Cases. Two female patients, 47 and
44 years old, were presented at the Dental Clinic of Vojvodina for endodontic
retreatment of teeth 22, 23 and 13, within the repeated prosthetic
restoration. Intraradicular individual cast posts were removed using
ultrasonic instruments. Remains of gutta-percha were removed by engine driven
rotary re-treatment files, root canals were shaped and cleaned using the
crown-down technique, and obturated with gutta-percha and epoxy-resin-based
sealer using the lateral compaction technique. Conclusion. When there are
metal posts or broken instruments in the root canal, the use of ultrasonic
instruments is considered a safe method characterized by negligible tooth
substance loss and minimal root damage causing fractures and perforations,
and the entire procedure is effective and predictable. Non-surgical
orthograde endodontic retreatment, when properly performed in accessible and
penetrable root canals, achieves a high cure rate, good and lasting results
and eliminates the need for radical procedures, such as apical surgery or
tooth extraction. When nonsurgical endodontic retreatment is done, treated
teeth must be restored by full coronal coverage as soon as possible, to
prevent coronal leakage or fracture.
