Implementation of IPAC Standards Through Best Practices During COVID-19 Pandemic

This article, Implementation of IPAC Standards Through Best Practices During COVID-19 Pandemic was penned by our very own Joan Hutchings RN, CPN, BA, MSc, MPA and appeared in the July / August 2020 edition of Oral Health Journal.

A Laboratory Comparison of Evacuation Devices on Aerosol Reduction

by Mary E. Jacks, RDH, MS Dental hygienists are responsible for creating a safe environment for themselves and their patients by implementing all safety recommendations when using an ultrasonic scaling device. To this end, numerous guidelines have been written by various government agencies and professional associations that are designed to protect oral health care personnel from potentially hazardous bacteria. Ultrasonic instrumentation is an accepted method of treatment for a variety of oral conditions. In the practice of dental hygiene, irritant solutions from ultrasonic scaling devices produce the therapeutic effects of lavage; however, the solutions also combine with blood, saliva, and…

Aerosols and Splatter In Dentistry

by Stephen K Harrel DDS and John Molinari PhD This research was conducted n 2004 and evidences how many dental procedures create aerosols and droplets as biproducts and these can become contaminated with bacteria and blood. These aerosols represent a potential route for disease transmission. Aerosols and Splatter In Dentistry

Respiratory Consequences of N95-Type Mask Usage In Pregnant Healthcare Workers, A Controlled Clinical Study This research was prepared by Pearl Shuang Ye Tong, Anita Sugam Kale, Kailyn Ng, Amelia Peiwen Loke, Mahesh Arjandas Choolani, Chin Leong Lim, Yiong Huak Chan, Yap Seng Chong, Paul, Anantharajah Tambyah, and Eu-Leong Yong. This research has been reprinted with permission. Background: Outbreaks of emerging infectious diseases have led to guidelines recommending the routine use of N95 respirators for healthcare workers, many of whom are women of childbearing age. The respiratory effects of prolonged respirator use on pregnant women are unclear although there has been…

Respiratory Virus Shedding In Exhaled Breath and Efficacy of Face Mask
Respiratory Virus Shedding In Exhaled Breath and Efficacy of Face Mask

This paper identifies seasonal human coronaviruses, influenza viruses and rhinoviruses in exhaled breath and coughs of children and adults with acute respiratory illness. Surgical face masks significantly reduced detection of influenza virus RNA in respiratory droplets and coronavirus RNA in aerosols, with a trend toward reduced detection of coronavirus RNA in respiratory droplets. Our results indicate that surgical face masks could prevent transmission of human coronaviruses and influenza viruses from symptomatic individuals.

The Lancet: Physical distancing, face masks, and eye protection’s role in preventing transmission of SARS-CoV-2 and COVID-19

Here’s some analysis of the role of physical distancing, face masks, and eye protection in preventing person-to-person transmission of SARS-CoV-2 and COVID-19: a systematic review and meta-analysis. This was published by The Lancet – 01 June 2020. As a PDF, read The Lancet: the effects of physical distancing, face masks, and eye protection on virus transmission in health-care. Evidence has been reviewed for other respiratory viral infections, mainly seasonal influenza. But as of this time, 04 June 2020 there is no comprehensive review available for information on SARS-CoV-2 or related betacoronaviruses that have caused these most recent epidemics.  Here is…
