safe removal of dental amalgam fillings containing mercury requires strict protocols to minimize mercury exposure to the patient, dental team, and environment. The most widely recognized standard is the IAOMT (International Academy of Oral Medicine and Toxicology) Safe Mercury Amalgam Removal Technique (SMART).
Here’s a summary of the key steps in a safe mercury amalgam removal protocol:
1. Personal Protective Equipment (PPE):
* Dentist and staff wear mercury-rated respirators, protective gowns, hair covers, and face shields.
* Patient wears a protective gown, hair cover, and a non-latex dental dam.
2. Isolation:
* Use of a rubber dam or dental dam to isolate the tooth and prevent mercury particles from being swallowed or inhaled.
* Seal around the dam with a material like Oraseal to reduce leakage.
3. Air Filtration:
* An oral aerosol vacuum/evacuator (high-volume suction) is positioned near the mouth.
* Operatory equipped with an amalgam separator and air purification system (HEPA + mercury v***r filters).
4. Oxygen Supply:
* The patient breathes external oxygen via a nasal mask to avoid inhaling mercury v***r.
5. Sectional Removal:
* The amalgam filling is cut into chunks using a cold-water spray and high-speed evacuation to reduce heat and mercury v***r release.
* Minimal drilling to avoid fine particulate release.
6. Continuous Suction:
* High-volume suction placed both in the oral cavity and external to the mouth.
7. Thorough Rinsing:
* After removal, the oral cavity is flushed with water and a slurry of charcoal, chlorella, or other binding agents (optional per practitioner).
8. Disposal & Cleanup:
* All amalgam waste is disposed of according to hazardous waste protocols.
* Operatory is cleaned with materials designed to trap mercury particles.
9. Post-Procedure Support: (Optional, varies by practitioner)
* Nutritional supplements or detox support may be recommended depending on patient health status.
Why these steps? Mercury v***r and particulate exposure increase during drilling/removal—these protections mitigate inhalation, ingestion, and dermal exposure.
