Dental care professionals are dangerous exposed to aerosols

Dental care professionals are dangerous exposed to aerosols



Dynamic Extraoral Aerosol Suction Unit External Oral Suction System DS1000


Abstract
Background
Dental care professionals are exposed to aerosols from the oral cavity of patients containing several pathogenic microorganisms. Bioaerosols generated during dental treatment are a potential hazard to dental staff, and there have been growing concerns about their role in transmission of various airborne infections and about reducing the risk of contamination.

Aims
To investigate qualitatively and quantitatively the bacterial and fungal aerosols before and during clinical sessions in two dental offices compared with controls.

Methods
An extra-oral evacuator system was used to measure bacterial and fungal aerosols. Macroscopic and microscopic analysis of bacterial species and fungal strains was performed and strains of bacteria and fungi were identified based on their metabolic properties using biochemical tests.

Results
Thirty-three bioaerosol samples were obtained. Quantitative and qualitative evaluation showed that during treatment, there is a significant increase in airborne concentration of bacteria and fungi. The microflora included mainly gram-positive organisms (Staphylococcus epidermidis and Micrococcus spp.), gram-positive rod-shaped bacteria and those creating endospores as well as non-porous bacteria and mould fungi (Cladosporium and Penicillium).

Conclusions
Exposure to the microorganisms identified is not a significant occupational hazard for dental care professionals; however, evidence-based prevention measures are recommended.

How to Select the uv sterilizer cabinet to Fight Covid-19

How to Select the uv sterilizer cabinet to Fight Covid-19

UV sterilization is a fast-growing and invaluable option for preventing the spread of hospital acquired infections, or HAIs. While you may have questions when it comes to what UV sterilization is and what it can do for your healthcare facility, there is no doubt that UV sterilization with uv sterilizer cabinet is incredibly effective in killing infectious bacteria, viruses, and fungi.


Why Use UV Sterilization?
UV sterilization is not a new technology, having been discovered in 1879. Discovered to be a useful technology for cleaning infectious spaces, more studies were done to determine the exact beneficial nature of UV for sterilization purposes. Since the 20th century, UV sterilization has been used to disinfect things like water and work surfaces. UV light is a shorter wavelength than visible light, and is able to penetrate and destroy the bodies of viruses and bacteria.

Where Can UV be Used?
While UV sterilization can be used as a supplemental infection control strategy for almost any situation, such as disinfecting water and work surfaces as mentioned above, the efficiency of the sterilization make other specialized spaces accessible as well.

How Can UV be Utilized?
Beyond water and surface sterilization, UV can be used as a sterilization technique for other types of disinfection. UV can disinfect the air in isolated spaces, which is particularly beneficial in a hospital setting. Installing UV devices like lamps and lights at the top of rooms and other areas of circulation can disinfect the air as it moves, improving both the air quality and the effectiveness of the UV sterilization.

What Type of UV Light is Best?
Most UV sterilization devices use UV-C Disinfection Lamp as the source of their disinfecting power. UV-C light is an effective solution for sterilization, which is why it is the most widely used light type. However, it can cause some serious damage as well. UV-C light can penetrate human skin and cause damage or injury to the person using it, if not careful. UV-C light can also cause damage to certain plastics and rubber materials over time.

When picking the right UV sterilizing device, the type of light used in the device is the most important factor in determining which device is the right one for your project. Because of its increased efficiency and improved safety, a device like the Far-UV Sterilray™ can be an incredible tool for sterilization and disinfection.

Something About Aerosol Management in Dentistry

The prevalence of harmful dental aerosols calls for appropriate infection control and preventive measurements in the practice to ensure the safety of both dental professionals and their patients. As soon as a patient steps into the dental clinic, the dentist and their team should make every attempt possible to ensure infection control and avoid cross-contamination of bacteria and viruses.

Gaining a clear health history for each patient, completing a thorough examination, and requiring patients to rinse with a microbial mouth rinse before treatments are all necessary best practices. When having the patient rinse prior to treatment, it is important to follow the recommended time according to the rinse. If the instructions recommend a 30-second rinse and the patient just swishes and spits within 10 seconds, for example, the benefits for the rinse are mitigated.

Protective equipment (including gloves), dental face masks that are ASTM level 3 if procedures produce aerosols, and protective eyewear should be worn at all times during procedures. Masks should cover the mouth and nose snugly, be single-use, and changed between each patient. Microbial accumulation in the waterline should be avoided by flushing it at the beginning of every day for at least 30 seconds and in between every patient. The correct positioning of a high volume suction evacuator beside the mouth and handpiece should be utilized and can minimize the production of aerosols by 90%.9.

In regard to the decontamination of air in the clinic, HEPA (high-efficiency particulate air) filters, ozonization, ionization, and air sterilization are four technologies targeting air quality. Some, though, are not reliable in getting completely rid of the pathogens.9 HEPA filters send air through various prefilters to assist with catching airborne particulate matter.

In regards to sterilization within the clinic, autoclaving dental handpieces sterilizes the external surfaces, and chemiclave achieves internal sterility. Handpieces should be sterilized after every patient, according to the CDC. Ammonia or enzymatic detergent with water should be used to clean suction lines at the end of every day. Using thin plastic bags to place on surfaces such as controls, handles, armrests, and handpieces within the clinic can help reduce surface contamination.

When practiced correctly, these measures can reduce the cross-contamination of infectious pathogens between people and the production of harmful dental aerosols in the clinic. However, there are further practical actions that should be taken to protect the airways of both dental professionals and their patients.
