Summary
Inferior dental nerve paresthesia can occur after dental procedures due to nerve injury. This case highlights a complication from gutta-percha in the mandibular canal during root canal therapy.
Area of Science:
- Dental Surgery
- Neurology
- Endodontics
Background:
- Paresthesia of the inferior dental nerve is a potential complication following various dental procedures.
- Nerve injury can result from mechanical, chemical, or thermal trauma during interventions like cystectomies, extractions, and surgeries.
Observation:
- A clinical case of inferior dental nerve paresthesia is presented.
- This complication arose after a gutta-percha point was introduced into the mandibular canal during root canal therapy of an inferior first molar.
Findings:
- The study details the etiology of nerve damage, including mechanical (compression, resection), chemical (toxic materials), and thermal (overheating) mechanisms.
- Wallerian degeneration (axonotmesis) or complete nerve sectioning (neurotmesis) can occur depending on the severity of the lesion.
Implications:
- Understanding these mechanisms is crucial for preventing and managing inferior dental nerve injuries.
- This case underscores the importance of careful technique in endodontic procedures to avoid iatrogenic nerve damage.
