Toxic materials in dentistry
A hazardous waste is a waste that, due to its characteristics of flammability, corrosiveness, reactivity, explosiveness or infectivity, poses a potential risk to the ecological balance or the environment, and its regulation and control is the responsibility of the Ministry of the Environment and Natural Resources (SEMARNAT) as specified in the General Law of Ecological Balance and Environmental Protection.1
The Mexican Official Environmental Protection Standard – Environmental Health – Biological and infectious hazardous waste – Classification and handling specifications NOM-087-ECOL-SSA1-2002 specifies that biological and infectious hazardous waste (BHWW) are blood in its liquid form, blood products, tissues and organs removed during surgery, and non-anatomical waste are those healing materials impregnated with blood or any body fluid and sharps.2
This standard classifies LLW generating facilities into three different levels based on the amount of waste produced daily; however, dental offices are erroneously not considered as waste generating facilities; however, unlike hospitals that produce large amounts of waste daily, dental offices can be considered as low waste producing facilities (level 1).3
Disposal of disclosing fluids
FDA recommends that used needles and other sharps be immediately placed in FDA-approved sharps disposal containers. FDA-approved sharps disposal containers are generally available at pharmacies, medical supply companies, health care providers, and over the Internet.
The FDA has evaluated the safety and effectiveness of these containers and has approved their use by healthcare professionals and the general public to help reduce the risk of injury and infection from sharps.
FDA-approved sharps disposal containers are made of rigid plastic and have a line marking when they should be considered full, which means it is time to discard the container. Examples of FDA-approved sharps containers are shown below:
If an FDA-approved container is not available, guidelines from some organizations and communities recommend the use of a sturdy plastic household container as an alternative. The container should be leak-proof, remain upright during use, and have an airtight, puncture-resistant lid, such as a plastic detergent container.

Weight loss. Pain or symptoms that awaken the person. Onset of discomfort at older ages, since it begins in adolescence or adulthood, not later. Presence of blood in the stool. Changes in the characteristics of the person’s usual symptoms. Alterations in the examinations.
There is no definitive cure for this condition, because it is chronic. There are measures to treat the symptoms and improve the quality of life of those who suffer from it, such as making a change in diet, reducing stress and in some cases, when the doctor determines it, taking medication.
When a patient has hemorrhoids that do not cause too much discomfort, the treatment consists of making the stool softer so that the patient exerts less force. In the case of bleeding and/or hemorrhoidal prolapse, if the above does not work, the possibility of intervention (elastic ligation or surgery) can be considered. To proceed to this step it is important to investigate the patient, i.e., verify that the symptoms come from the hemorrhoids and not from elsewhere (rule out polyps, colon cancer, arteriovenous malformation or any inflammatory disease of the colon and / or rectum). If the person has mixed hemorrhoids, with an important external component that are large and produce bleeding, traditional surgery is indicated, which is painful and slow recovery (20 to 30 days). But when they are essentially internal, PPH surgery tends to be preferred, which is a modern method that produces little discomfort, is less uncomfortable and quick recovery. It consists of returning the hemorrhoids to their original place by means of brackets placed inside the anal canal.
