Nonessential and Essential Fatty Acids Fatty acids are vital for the normal operation of all body systems. The circulatory system, respiratory system, integumentary system, immune system, brain, and other organs require fatty acids for proper function.

The WHO guidance cites the high risk of dental professionals either being infected with SARS-CoV-2 or passing the infection to patients. It also encourages providers to use alternative means to promote good oral care during the pandemic.

Editor's note: This is a developing story. Updates through August 31, 2020, are detailed at the conclusion of the article.
In a guidance dated August 3, 2020, the World Health Organization (WHO) issued recommendations for the provision of essential oral health services in the context of COVID-19.1 The guidance, which is addressed to public health decision makers and dental providers, recommends prioritizing essential dental care and the delaying of nonessential dental care where COVID-19 is in an area of community transmission and not reduced to cluster cases. However, the WHO guidance also advises that oral health-care providers follow recommendations from local officials, be they on the national or community level.
The WHO has previously defined 'community transmission' as 'the inability to relate confirmed cases through chains of transmission for a large number of cases, or by increasing positive tests through sentinel samples (routine systematic testing of respiratory samples from established laboratories).'2
The guidance opens with a discussion of COVID-19 transmission, aerosol-generating procedures, and the unique infection risks faced by dental providers. The guidance then states as follows: 'WHO advises that routine non-essential oral health care—which usually includes oral health check-ups, dental cleanings and preventive care—be delayed until there has been sufficient reduction in COVID-19 transmission rates from community transmission to cluster cases or according to official recommendations at national, sub-national or local level. The same applies to aesthetic dental treatments. However, urgent or emergency oral health care interventions that are vital for preserving a person's oral functioning, managing severe pain or securing quality of life should be provided.'
The WHO recommendations began to receive increased attention by the United States dental community today, as stories by Reuters,3The Hill,4 and Voice of America5 placed a spotlight on the WHO's recommendation to delay nonessential care. The guidance was also amplified by a WHO tweet earlier this morning, which stressed the prioritization of urgent cases and COVID-19 screening (figure 1).

Reuters reported on the guidance after coverage of a news briefing in which Benoit Varenne, a WHO dental officer, said dental providers should 'avoid or minimize procedures that may generate aerosol, prioritize a set of clinical interventions that are performed using an instrument, and of course to delay routine nonessential oral health care.”3
Call of duty 2 (2005). According to Reuters, Varenne also noted that more research was needed to ascertain the likelihood of COVID-19 transmission in dental settings.
In the United States, the WHO guidance provides an additional layer of advisement for government officials, dental boards, dental providers, and patients to consider. Since the pandemic began, recommendations have come from state government, the Centers for Disease Control and Prevention, the American Dental Association, the American Dental Hygienists' Association, state dental associations, specialist organizations, and the Occupational Safety and Health Administration, among others. Recommendations have complemented each other at times, but in other instances have appeared incongruent—especially in regard to the risks associated with aerosol-generating dental care and how to mitigate those risks. The confusion has caused tension within some areas of the profession.
Other WHO recommendations from the August 3 guidance include the following:
- Patients should be given oral health advice through remote consults or social media on how to maintain good oral hygiene, as prevention and self-care are high priorities.
- Oral health-care workers are in close proximity to patients’ faces for long periods of time, and there is frequent exposure to saliva, blood, and bodily fluids and handling of sharp instruments. As such, dental providers 'are at high risk of being infected with SARS-CoV-2 or passing the infection to patients.'
- Adequate ventilation is needed in dental settings. Facilities should '[a]void the use of split air conditioning or other types of recirculation devices and consider installation of filtration systems.'
