The number of regulations governing dental waste and its disposal is continually expanding. Dental waste disposal is already a precise operation, but it is constantly updated to prevent materials from seeping into the environment. There are four categories of dental waste, each with its guidelines for proper disposal. In this essay, we will cover the many types of dental waste and their disposal techniques.
- Amalgam
- Pharmaceuticals
- Hazardous
- Sharps
Dental Amalgam Waste Disposal
The American National Standards Institute/American Dental Association (ANSI/ADA) defines amalgam waste as "including amalgam (scrap), chair-side trap filters containing amalgam, vacuum pump filters containing amalgam, saliva ejectors if used in dental procedures involving amalgam, used amalgam capsules, tooth extractions with amalgam restorations, and waste items that are contaminated with amalgam." If not properly disposed of, amalgam waste has the potential to pollute waterways and the environment, as well as have an influence on a community.
The most effective strategies to keep amalgam waste out of the environment are to utilize amalgam separators and implement an amalgam recycling program. As of 2017, the Environmental Protection Agency (EPA) mandated that amalgam separators exhibit at least 95% removal efficiency. The separated amalgam waste cannot be dumped in the trash. Instead, it must be delivered to a facility that specializes in melting metals and recycling mercury.
Pharmaceutical Waste Disposal
The EPA defines pharmaceutical waste as expired, unwanted, or unused medications. "Healthcare institutions and healthcare-related companies that generate pharmaceutical wastes are liable for properly handling their wastes per all local, state, and national environmental regulations." This management can take the form of take-back programs or incinerated in a hazardous waste combustion unit. Mail-back systems exist as an easy and affordable means to dispose of gathered pharmaceutical waste. The EPA defines hazardous waste disposal as waste that poses "substantial or potential threats to public health or the environment". To be designated as hazardous, waste must have one of the following characteristics: ignitability, reactivity, corrosion, or toxicity. Hazardous waste can be in any physical state, including liquid, gaseous, and solid. The type of disposal is determined by the physical state of the trash and whether or not it requires further treatment.
Countermeasures such as solidification or the construction of waste-containment barriers may be required to prevent hazardous waste from reaching the environment. One thing is certain: hazardous trash cannot be tossed away or washed down the sink.
Sharps are defined by the United States Food and Drug Administration (FDA) as any equipment or object used to puncture or lacerate flesh. Common things utilized in dental offices include needles for the skin, disposable scalpels and blades, damaged glass, and some polymers. Once used in this manner, a sharp is now classified as bio-hazardous waste and must be appropriately disposed of in a sharps container. Sharps mail-back systems allow healthcare facilities and self-injectors to safely dispose of and recycle sharps waste.
Dental waste must be appropriately processed and disposed of to avoid contaminating the environment or adjacent communities. The many medical waste treatment options help to safeguard the environment, and mail-back systems are consistently the most convenient way to move medical waste from a dental institution safely and efficiently.
