Summary
Sodium hypochlorite, a common dental irrigant, was accidentally introduced into the maxillary sinus during root canal therapy. Fortunately, sterile water irrigation prevented expected complications like pain and swelling.
Area of Science:
- Endodontics
- Oral and Maxillofacial Surgery
- Dental Traumatology
Background:
- Root canal treatment involves irrigating the root canal system.
- Sodium hypochlorite is a widely used irrigant in endodontics.
- The maxillary sinus is anatomically adjacent to the roots of maxillary posterior teeth.
Observation:
- Sodium hypochlorite was inadvertently injected into the maxillary sinus during root canal treatment of a right maxillary first molar.
- The sinus was irrigated with sterile water through the palatal canal.
Findings:
- Despite the inadvertent injection of sodium hypochlorite into the maxillary sinus, the expected sequelae did not occur.
- No significant pain, edema, or hemorrhage was experienced by the patient.
Implications:
- This case suggests that sterile water irrigation may be an effective measure to mitigate complications from accidental sodium hypochlorite extrusion into the maxillary sinus.
- Further investigation is warranted to confirm the efficacy and safety of this management approach.
- Clinicians should be aware of the potential for sinus communication during endodontic procedures and be prepared for management strategies.
