Note: Many liquid disinfectants and sterilants are used alone or in combinations in the healthcare setting. (These include alcohols, chlorine compounds, formaldehyde, glutaraldehyde, ortho-phthalaldeyde, hydrogen peroxide, iodophors, peracetic acid, phenolics, and quaternary ammonium compounds.)

Simply so, what level of disinfectant should be used in the dental office?

OSHA requires surface disinfectants to be efficacious against HIV and HBV. If blood is present on the surface, an intermediate-level disinfectant labeled as tuberculocidal should be used. The CDC states that liquid chemical sterilants should not be used as an environmental surface disinfectant.

Subsequently, question is, what is Surface disinfectant? Disinfectants are antimicrobial agents designed to inactivate or destroy microorganisms on inert surfaces. Disinfectants are frequently used in hospitals, dental surgeries, kitchens, and bathrooms to kill infectious organisms.

Secondly, what is disinfection in dentistry?

Disinfection is less lethal than sterilization, because it destroys the majority of recognized pathogenic microorganisms, but not necessarily all microbial forms (e.g., bacterial spores).(CDC guidelines 2008) ? Disinfection is a process of removing or killing most, but not all, viable organisms.

How long should disinfectant stay on a surface before wiping?

The contact time will vary with the chemical being used. Many chemicals have a contact time of 10 minutes. This means that the surface that is being treated should stay wet after cleaning and disinfecting for 10 minutes.

What chemicals are used in dentistry?

Some common chemical sterilants and disinfectants used in dental offices include glutaraldehyde, glutaraldehyde with phenol, hydrogen peroxide, hydrogen peroxide with peracetic acid, ortho-phthalalhyde (OPA), alcohols (ethyl, isopropyl), quatemary ammonium chloride, oxidizers (bleach), formaldehyde and phenolics.

How do dentists sterilize equipment?

Most dental instruments are sterilized in special machines; it takes much more than just soap and water to make sure instruments are free of bacteria. Recommended sterilization methods include placing these tools into an autoclave (steam under pressure), a dry-heat oven or chemical vapor (commonly called a chemiclave).

What procedure do you use to sterilize dental equipment?

Steam autoclave
Steam autoclaves are the most commonly used type of heat sterilizer in dental practices. Two types of processes employ steam under pressure. The difference between the two is the manner in which the machine evacuates the air from the sterilization chamber and then introduces the steam.

Why is chemistry needed for dentistry?

Advances in chemistry have helped us develop effective pain relief, design more robust materials for fillings, and find better ways to repair and replace teeth. Because so much of dental science derives from chemistry, it is now a prerequisite for dentistry courses at university.

Which agency regulates disinfectants?


U.S. Environmental Protection Agency (EPA)

Does Lysol wipes kill bloodborne pathogens?

Clorox wipes and Lysol type products will kill many infectious organisms but will not kill blood borne pathogens. Contact custodian for clean-up of blood or body fluid “spills”.

Why is sterilization important in dentistry?

Sound sterilization practices in dentistry protect patients, dentists and the whole dental team. They prevent the growth of bacteria on instruments and surfaces throughout the dental practice. When proper sterilization procedures aren't used they can pass from one patient to another.

What is the aim of Sterilisation process?

The aim of sterilization is to break the chain of potential cross-infection between patients by killing micro-organisms, including spores.

What is the purpose of disinfection?


Disinfection refers to the application of a chemical agent to destroy or inhibit the growth of microorganisms on the surface of an instrument or surgical device. These chemical agents are known as disinfectants and antiseptics. 1.

What is dental autoclave?

Also called a steam sterilizer, the autoclave is the machine that harnesses the power of high temperature and high-pressure steam in order to sterilize germs on dental equipment, such as forceps, intended for reuse, thus ensuring its safety for the next patient.

What are critical dental instruments?

Dental instruments should be classified as: Critical – Surgical instruments and other invasive devices used to penetrate soft tissue or bone. Examples are: forceps, scalpels, bone chisels, scalers and burs. Semi-CriticalInstruments that do not penetrate soft tissues or bone but contact oral tissues.

How long does cold sterilization take?

Items placed in the solution can be disinfected at a high level, meaning that most microorganisms, but not bacterial spores, are killed. This occurs in 15 to 30 minutes, depending on the product. Sterilization can occur if the items are left in the solution for the required time, typically three to six hours.

What is high level disinfection?

High-Level Disinfection. High-Level Disinfection Description: High-Level Disinfection (HLD) refers to the treatment of medical devices and dental instruments to inhibit most viable microorganisms, except some spores and prions when present in a significant load.

How do autoclaves sterilize?


Many autoclaves are used to sterilize equipment and supplies by subjecting them to pressurized saturated steam at 121 °C (250 °F) for around 15–20 minutes depending on the size of the load and the contents The autoclave was invented by Charles Chamberland in 1884, although a precursor known as the steam digester was

How do you clean dental instruments?

Debris can be removed from an instrument either by scrubbing the instrument manually with a surfactant or detergent and water or by using automated equipment (e.g., ultrasonic cleaner, washer-disinfector) and chemical agents.

What are the 3 levels of disinfection?

There are three levels of disinfection: high, intermediate, and low. The high-level disinfection (HLD) process kills all vegetative microorganisms, mycobacteria, lipid and nonlipid viruses, fungal spores, and some bacterial spores.
