Summary
External root resorption (ERR) can occur after connective tissue graft surgery. Careful surgical technique and potential biomodification may help prevent this rare complication in patients undergoing root recession treatment.
Area of Science:
- Periodontology
- Oral Surgery
Background:
- Connective tissue graft (CTG) surgery is a common procedure for treating gingival recession.
- External root resorption (ERR) is a rare but serious complication following periodontal surgery.
Observation:
- An unusual case of external root resorption (ERR) developed in a 37-year-old male one year after partial-thickness connective tissue graft surgery.
- The resorptive lesion was treated with flap surgery and root planing, with successful uneventful healing.
Findings:
- The affected tooth remained vital, and no recurrence of ERR was observed during over one year of follow-up.
- This case highlights the potential for delayed onset of ERR following CTG procedures.
Implications:
- Clinicians should be aware of the possibility of delayed ERR after connective tissue graft surgery.
- Further research into techniques like retaining donor periosteum and root biomodification may mitigate the risk of ERR.
