Aerosols and droplets generated during speech have been implicated in the person-to-person transmission of viruses,1,2 and there is current interest in understanding the mechanisms responsible for the spread of Covid-19 by these means. The act of speaking generates oral fluid droplets that vary widely in size,1 and these droplets can harbor infectious virus particles. Whereas large droplets fall quickly to the ground, small droplets can dehydrate and linger as “droplet nuclei” in the air, where they behave like an aerosol and thereby expand the spatial extent of emitted infectious particles.2 We report the results of a laser light-scattering experiment in which speech-generated droplets and their trajectories were visualized.

The output from a 532-nm green laser operating at 2.5-W optical power was transformed into a light sheet that was approximately 1 mm thick and 150 mm tall.

Dentist: Closure of practices impacts patients’ oral health

JOHNSTON, R.I. (WPRI) ─ A Johnston dentist believes dentistry is an essential business, but argues that it hasn’t been treated as such throughout the coronavirus pandemic.

Rupesh Udeshi, dentist and co-owner of Dental Associates of Rhode Island, said the months his practice was closed had a big impact on the health of many of his patients.

“We’ve had a great backlog and problems that were minor, that have become major. The patient may have just had a cavity or needed a filling, but we haven’t seen them and it’s now more severe and it’s a root canal, and some people who maybe needed a root canal ─ now they need to have the tooth out,” he said.

The World Health Organization recently recommended delaying routine dental care because of the pandemic. But the American Dental Association says they “respectfully yet strongly disagrees.”

“Oral health is integral to overall health. Dentistry

Dentists, Orthodontists, and Other Oral Health Care Providers

Many different types of oral health care providers could become involved in the care of your teeth, gums, and mouth. A brief description of these various health care providers is as follows:


General Dentist

A general dentist is your primary care dental provider. This dentist diagnoses, treats, and manages your overall oral health care needs, including gum care, root canals, fillings, crowns, veneers, bridges, and preventive education.

All practicing general dentists have earned either a DDS or DMD degree (doctor of dental surgery or doctor of dental medicine, respectively). There is no difference between the two degrees or the curriculum requirements that dentists must meet. Some schools simply award the one degree, while others award the other.

Generally, three or more years of undergraduate education plus four years of dental school is required to become a general dentist. Additional post-graduate training is required to become a
