Summary
Accidental root canal filling material in the inferior dental nerve canal caused bilateral nerve numbness. Prompt surgical intervention is crucial for managing this dental complication.
Area of Science:
- Dentistry
- Oral Surgery
- Neurology
Background:
- Root canal therapy aims to preserve teeth but carries risks.
- The inferior dental nerve is susceptible to iatrogenic injury during endodontic procedures.
- Accidental extrusion of root canal filling materials can lead to nerve damage.
Observation:
- A patient presented with bilateral paraesthesia of the inferior dental nerve.
- This complication occurred after root canal filling material was inadvertently introduced into the nerve canal.
- The paraesthesia indicated nerve dysfunction or damage.
Findings:
- The case highlights the potential for severe neurological complications from endodontic overfilling.
- Early detection of inferior dental nerve paraesthesia is critical.
- Surgical intervention may be necessary to address the extruded material and nerve impingement.
Implications:
- This case underscores the importance of meticulous technique in root canal procedures.
- Prompt surgical management can potentially improve outcomes for nerve injury.
- Awareness of this complication is vital for endodontists and oral surgeons.
