Health Ministry Investigates Arsenic Use in Dental Procedures and Pharmaceuticals
Table of Contents
A comprehensive review of drug registration and approval data is underway as health officials investigate the potential risks associated with arsenic-containing medications, including those used in pulp necrosis treatments and even a potential bone marrow-destroying drug. The move comes amid growing concerns from experts and a recent police crackdown on the illegal production and sale of arsenic trioxide – commonly known as white arsenic – to dental clinics.
The Ministry of Health and Welfare initiated the review after uncovering a network illegally manufacturing and distributing the dangerous substance. This prompted a broader examination of approved medical supplies and pharmaceuticals containing arsenic, and whether current regulations adequately protect public health.
Illegal Arsenic Sales to Dental Clinics Uncovered
Authorities recently dismantled an organization that was hand-producing and selling arsenic trioxide to various dental practices. This illicit operation raises serious questions about the sourcing of materials and the potential for improper use of a highly toxic substance within dental procedures.
A senior official stated that, as of now, “there are no dental medical devices that use arsenic,” but acknowledged the department has not yet received definitive confirmation regarding the approval status of dental supplies or materials containing the element. The Ministry’s Medical Examination and Treatment Management Department has pledged to review and revise regulations governing the use of arsenic-containing medications, including those intended to induce abortion.
Concerns Over Pulp Necrosis Agents and Modern Alternatives
The investigation extends to pulp necrosis agents, historically used to kill the nerve in a tooth before a root canal. While still potentially approved for use, experts are questioning the continued validity of their effectiveness and the inherent health risks if not strictly controlled.
Professor Vo Truong Nu Ngoc of Hanoi Medical School, with extensive experience in dental and maxillofacial surgery training, noted that the current curriculum does not include instruction on using arsenic or formaldehyde in root canal treatments. “There is currently no official information from the Ministry of Health banning the use of arsenic-containing pulp necrosis agents,” Professor Ngoc explained, “but dentists should prioritize updating their knowledge with advanced technologies and methods to ensure safer patient care.”
Alternatives to root canal treatment, such as the use of local anesthetics, are readily available. A variety of anesthetics exist, and while allergic reactions are rare, a patch test is recommended for patients with a history of allergies. General anesthesia can be considered for those with broader anesthetic sensitivities.
Echoes of Mercury Fillings: A History of Phasing Out Harmful Materials
This investigation echoes past concerns regarding the use of mercury in dental fillings. In 2019, the Office of the Inspector General recommended that dental facilities avoid using mercury-containing fillings for children under 15, pregnant women, and nursing mothers. A phased approach to eliminate these fillings began in 2021, encouraging the adoption of safer, readily available alternatives.
According to the Office of the Inspector General, mercury-based fillings – which can contain up to 50% mercury – pose risks to both environmental and public health, particularly for vulnerable populations. This history underscores the importance of proactive regulation and the continuous evaluation of materials used in dental care.
The Ministry of Health and Welfare’s current review signals a commitment to patient safety and a willingness to address potential risks associated with potentially harmful substances in medical and dental practices. The outcome of this investigation could lead to significant changes in the approval process for pharmaceuticals and dental materials, ultimately prioritizing public health and well-being.
