Summary
Persistent sinus tracts, often linked to root perforations after dental procedures like post removal, may require surgical exploration. Prompt treatment with mineral trioxide aggregate and bone grafting can resolve these complex cases.
Area of Science:
- Endodontics
- Oral Surgery
Background:
- Sinus tracts are drainage pathways for abscesses, commonly resolving with endodontic therapy.
- Persistent sinus tracts that resist conventional treatment necessitate further investigation to identify the underlying cause.
Observation:
- A case involving a 53-year-old female patient with two persistent, non-healing sinus tracts near the maxillary left incisor.
- The patient had a history of difficult cast post-and-core removal from the compromised tooth one year prior.
Findings:
- Surgical exploration revealed two separate root perforations as the cause of chronic inflammation.
- The perforations were successfully treated by removing granulation tissue and sealing with mineral trioxide aggregate (MTA).
- Bone grafting was performed in areas of bone resorption.
Implications:
- This case highlights potential complications associated with post preparation and removal.
- Explorative surgery is crucial for diagnosing the etiology of persistent sinus tracts when conservative treatments fail.
- Successful management of root perforations and associated bone loss can be achieved with surgical intervention and appropriate materials.
