Question 72 · LDEK · Endodontic retreatment

A 54 year-old man was referred for a treatment of tooth 47. The patient’s current condition is good. The patient is diabetic and registered for regular specialized care. Intraoral examination reveals satisfactory dental hygiene and no additional dental treatment is needed. In tooth 47 the loss of filling on the mesial surface and the exposure of guta percha on the floor of the pulp chamber are detected. The X-ray has revealed proper root canal obturation and no changes in the periapical region. Which of the following is recommended in the described case?

  1. A. RCT of tooth 47 with antibiotic prophylaxis.
  2. B. disinfection of the pulp chamber and the placement of temporary filling for 2 weeks; then - in the absence of ailments - replacement of the temporary filling with a permanent one.
  3. C. patient referral for extraction of tooth 47 due to systemic disease.
  4. D. consultation of the treatment plan with a diabetologist.
  5. E. RCT of tooth 47 without prophylactic antibiotic therapy.
Hint

Ask what exposure of the root filling to saliva means for the canal seal, and whether controlled diabetes calls for antibiotic cover.
