Paresthesia from N2. Report of a case
Oral Surgery, Oral Medicine, and Oral Pathology
|November 1, 1978
Summary
Paraformaldehyde-containing root canal cements, such as N2, have been linked to paresthesia. This disabling nerve condition necessitates avoiding these materials for root canal obturation.
Area of Science:
- Endodontics
- Dental Materials Science
- Neuroscience
Background:
- Root canal therapy aims to eliminate infection and restore tooth function.
- Various obturation materials are used to fill the root canal system.
- Paraformaldehyde is a component in some commonly used root canal cements.
Observation:
- Reports indicate paresthesia following the use of N2 and similar root canal cements.
- Paresthesia is a sensory disturbance involving tingling or numbness.
- This condition can be persistent and significantly impact daily life.
Findings:
- A causal link is suggested between paraformaldehyde-containing cements and paresthesia.
- The long-lasting and disabling nature of paresthesia is a significant concern.
- The risk of inducing paresthesia outweighs the benefits of these specific cements.
Implications:
- Clinicians should avoid using paraformaldehyde-containing cements for root canal obturation.
- Alternative, safer obturation materials should be prioritized in endodontic practice.
- Further research into the neurotoxic mechanisms of dental materials may be warranted.
