Summary
Arsenical paste leakage from root canal treated teeth can cause severe maxillary bone loss. This case highlights the dangers of using outdated and hazardous arsenic-based dental materials.
Area of Science:
- Dentistry
- Oral Surgery
- Toxicology
Background:
- Historically, arsenic compounds were used in endodontics as a devitalizing agent.
- The use of arsenic in dental procedures is now largely obsolete due to safety concerns.
Observation:
- A patient presented with significant alveolar bone loss in the maxilla.
- The bone loss was traced to leakage of an arsenical paste from a tooth previously treated endodontically.
Findings:
- The arsenical paste migrated from the pulp chamber into the surrounding maxillary tissues.
- This migration resulted in severe localized destruction of the alveolar bone.
Implications:
- This case underscores the severe risks associated with historical dental practices involving arsenic.
- It emphasizes the need for stringent safety protocols and the avoidance of dangerous, outdated medicaments in modern dentistry.
