which type of disease transmission occurs when spatter is created during dental treatment?

by Alvera Hayes II Published 3 years ago Updated 2 years ago

Thus, splatter droplets also may be a potential source of infection in a dental treatment setting. Splatter and droplet nuclei also have been implicated in the transmission of diseases other than TB, such as SARS, measles and herpetic viruses. Some diseases known to be spread via an airborne route are listed in Table 1.

The usual method for transmission of TB is through the formation of droplet nuclei. 15 These form when a droplet of sputum or saliva containing Mycobacterium tuberculosis is projected from the patient by coughing or potentially by splatter from a dental procedure.Dec 29, 2014

How do you know if you have a dental spatter?

Primary Modes of Disease Transmission in Dentistry: CDC Direct Transmission. Direct transmission of pathogens occurs through person-to-person contact. An example would be …

What type of disease transmission is most common in dental offices?

One micro-organism of which transmission has been established in an oral surgery practice is hepatitis C virus (HCV). Molecular typing methods have been used to study the possible transmission of HCV in over 4000 patients after they visited a dental office [29, 30].Oct 25, 2018

What is splatter in dentistry?

As the droplet begins to evaporate, the size of the droplet becomes smaller, and it then has the potential to stay airborne or to become reairborne as a dust particle. Thus, splatter droplets also may be a potential source of infection in a dental treatment setting.

What are infections transmitted during dental practice?

Dental health care professionals are at risk for acquiring or transmitting hepatitis B, influenza, measles, mumps, rubella and varicella. All these diseases are vaccine-preventable.Jan 30, 2018

What diseases can you get from the dentist?

There is evidence of transmission of HBV, HIV and HCV in the dental office, and those who are not immune to HBV are particularly vulnerable. There is also evidence of transmission of upper respiratory viruses and herpes viruses in the dental office.

What is splatter transmission?

Splatter evaporates, leaving smaller particles called droplet nuclei, which can carry bacteria and viruses and transmit various diseases such as SARS and tuberculosis [5].

What is a splash splatter and droplet surface?

touch, transfer, and splash/spatter/droplet. touch surfaces. directly touched and contaminated during dental treatment. transfer surfaces. not directly touched but often are touched by contaminated instruments.

What is direct transmission?

In direct transmission, an infectious agent is transferred from a reservoir to a susceptible host by direct contact or droplet spread. Direct contact occurs through skin-to-skin contact, kissing, and sexual intercourse. Direct contact also refers to contact with soil or vegetation harboring infectious organisms.

What is cross-infection in dentistry?

Cross-infection is the transmission of pathogenic bacteria from one individual to another. The process of reducing this transmission risk is known as infection control.

What is cross contamination in dentistry?

In short, cross contamination is a spread of microorganisms from one source to another. In dentistry, cross contamination can occur by direct contact with microorganisms from patient to patient or patient to dentist and vice versa (droplet transmission and inhalation of airborne pathogens).

What is a dental virus?

Viral infections of the oral cavity usually manifest as either ulceration or blistering presentation of oral tissues. Oral viral infections are encountered in dental practice but received less clinical interest due to the lesser frequency of patients and diagnostic challenges.

What are the barriers used in dental care?

To prevent contact with splashes and spatter, dental health care personnel should position patients properly and make appropriate use of barriers (e.g., faceshields, surgical masks, gowns), rubber dams, and high-volume evacuators.

Can a bloodborne pathogen be transmitted by an aerosol?

Although it is known that bloodborne pathogens can be transmitted through mucous membrane exposure, there are no known instances of a bloodborne pathogen being transmitted by an aerosol in a clinical setting.

ABSTRACT

Aerosols and droplets are produced during many dental procedures. With the advent of the droplet-spread disease severe acute respiratory syndrome, or SARS, a review of the infection control procedures for aerosols is warranted.

DISEASE TRANSMISSION THROUGH AN AIRBORNE ROUTE

The potential routes for the spread of infection in a dental office are direct contact with body fluids of an infected patient, contact with environmental surfaces or instruments that have been contaminated by the patient and contact with infectious particles from the patient that have become airborne.

DENTAL AEROSOL AND SPLATTER

Studies on dental aerobiology, I: bacterial aerosols generated during dental procedures.

SOURCES OF AIRBORNE CONTAMINATION DURING DENTAL TREATMENT

There are at least three potential sources of airborne contamination during dental treatment: dental instrumentation, saliva and respiratory sources, and the operative site. Contamination from dental instrumentation is the result of organisms on instruments and in DUWLs.

SALIVA AND RESPIRATORY SOURCES OF CONTAMINATION

The oral environment is inherently wet with saliva that continuously replenishes the fluid in the mouth. The fluids in the mouth are grossly contaminated with bacteria and viruses. Dental plaque, both supragingival and in the periodontal pocket, is a major source of these organisms.

CONTAMINATION FROM THE OPERATIVE SITE

Most dental procedures that use mechanical instrumentation will produce airborne particles from the site where the instrument is used. Dental handpieces, ultrasonic scalers, air polishers and air abrasion units produce the most visible aerosols.

COMPOSITION OF DENTAL AEROSOLS

Qualitative and quantitative analysis of the makeup of dental aerosols would be extremely difficult, and the composition of aerosols probably varies with each patient and operative site.
