Quick summary:

When performing or participating in aerosol-generating procedures (respiratory tract open sputum aspiration, sputum induction, etc.), dental health personnel should continue to wear NIOSH approved N95, N95 equivalent or higher level masks. Details on the use of N95 and other safety measures can be found in the CDC’s recently updated interim infection prevention and control recommendations. If dentists, dental team members, and patients are not involved in the aerosol generation process, they should continue to wear appropriate masks in the dental clinic, whether vaccinated or not.

Dental professionals are increasingly challenged to provide infection control for their patients, while protecting themselves.

It is important for dental professionals to wear protective equipment

N95-face-mask online shop is the choice for more healthcare professionals where comfort and protection are needed in a variety of procedures. We offer a full range of styles, features and levels of protection. From different brands of N95 respirators we provided including：NIOSH approved Surgical N95 respirators ans standard N95s

1 ASTM Low Barrier:For procedures where fluid, spatter, and/or aerosols are produced in low concentrations.

Procedures:- Patient Exams- Operatory Cleaning/Maintenance- Impressions- Lab Trimming, Finishing r Polishing Orthodontics

2 ASTM Moderate Barrier: For procedures where generation of fluid, spatter and/or aerosols is moderate.
Procedures:- Restorative/CompositesEndodontics- Propbylaxis- SealantsScaling Root Planning- Limited Oral Surgery

3 ASTM High Barrier: For procedures where heavy to moderate levels of fluid, spatter and/or aerosols are produced. Procedures: Crown Preparation- Implant PlacementUse of Ultrasonic ScalerUse of Piezo Scaler with Wateror Medicaments- Periodontal SurgeryComplex Oral Surgery

Surgical face masks are medical devices regulated by the Food and Drug Administration（FDA).

Mask use in health care was initially recommended for protection against bacteria and viruses aerosolized during treatment. As further knowledge was obtained concerning respiratory infections and their control, the rationale for wearing masks was expanded to include protection against spatter particles, splashes, and aerosols. The highest concentration of dental aerosols is found within 2 feet in front of the patient, typically where a dental care provider is positioned. The extent of exposure to aerosolized particles during dental procedures can be extensive. In addition, as larger droplets evaporate, residual droplet nuclei, smaller than 10 microns (um) in diameter, form and can remain airborne for extended periods in dental treatment areas. Ninety-five percent of dental treatmentgenerated aerosols are 5 um or less in diameter and contain multiple types of pathogenic bacteria and viruses. Masks that cover the nose and mouth can protect health professionals when used properly.

Masks that cover the nose and mouth.The filtration capabilities of masks protect health professionals when used properly.are determined by:Masks should be changed:

1. For each patient;
2After 1 hour during prolonged treatment procedures;
3.Every 20 minutes in a highly aerosolized environment.

The filtration capabilities of masks are determined by:

1.Size of the pores in the mask in microns.
2.Filtration efficiency, as measured by the percentage of particles filtered out by the mask.
