Question 157 · LDEK · Endodontic retreatment
A patient comes to the dental office for the radiological control of the tooth previously treated endodontically and filled with the method of lateral gutta-percha compaction with an epoxy resin sealer. The X-ray image revealed the enlargement of the periapical lesion at the root of the tooth with inadequate root canal filling. Indicate the correct management in this case:
- A. observation and another radiological control in 3-4 months.
- B. retreatment of the previously treated root canal with 2% chlorhexidine to remove the filling material from the canal.
- C. retreatment of the previously treated root canal with Lentulo drill to remove the filling material from the canal.
- D. retreatment of the previously treated root canal with heated Hedström file to remove the filling material from the canal.
- E. resection of the tooth root.
Hint
An enlarging lesion with an inadequate root filling calls for an orthograde approach; consider which method actually removes gutta-percha.
