Summary
Guided tissue regeneration (GTR) can rarely lead to root resorption and ankylosis. This case highlights a significant risk of these complications after GTR, potentially limiting its clinical use.
Area of Science:
- Periodontology
- Regenerative Dentistry
Background:
- Guided tissue regeneration (GTR) is a periodontal technique used to restore lost tissues.
- While generally successful, rare complications like root resorption and ankylosis have been noted.
Observation:
- A case of severe root resorption occurred two years post-GTR for a Class II furcation defect.
- The defect contained epithelium, connective tissue with inflammation, and membrane fragments.
- Ankylosis was also observed in conjunction with root resorption.
Findings:
- Histological examination revealed root resorption extending to the pulp chamber.
- Evidence of ankylosis was present in areas of root resorption.
- Inflammatory infiltrate and residual membrane material were found within the defect.
Implications:
- This case suggests a higher risk of root resorption and ankylosis following GTR than previously thought.
- These findings may necessitate a re-evaluation of GTR indications.
- Further research is needed to understand and mitigate these potential adverse outcomes.
