Summary
Endodontic retreatment of a maxillary molar resolved sinus pathosis quickly. This case suggests a link between root canal issues and maxillary sinus pseudocysts, with no recurrence at 13 months.
Area of Science:
- Dentistry
- Endodontics
- Oral Surgery
Background:
- Maxillary sinus pathosis can complicate endodontic treatment.
- Endodontic retreatment is a viable option for persistent apical periodontitis.
Observation:
- A case report details endodontic retreatment of a maxillary second molar.
- The patient presented with sinus radiopacity, suggesting maxillary sinus involvement.
Findings:
- Successful root canal debridement led to the disappearance of sinus pathosis within 6 days.
- A direct relationship was suggested between apical periodontitis and a maxillary sinus pseudocyst.
Implications:
- This case highlights the potential for endodontic treatment to resolve associated sinus pathology.
- It underscores the importance of considering odontogenic sources for maxillary sinus pseudocysts.
- Long-term follow-up confirmed the resolution of both endodontic and sinus issues.
