INFECTION CONTROL PROTOCOL DURING COVID-19 IN DENTISTRY
This document outlines infection control protocols for dental practices during the COVID-19 pandemic. It discusses personal protective equipment, patient handling protocols, waste management, instrument reprocessing, zoning within dental clinics, and guidelines from health organizations. Proper hand hygiene and the use of PPE like masks, gloves, and gowns are essential. High-risk aerosol-generating procedures require full PPE including N95 masks and face shields. Treatment areas must be disinfected after each patient. Non-emergency dental care may be postponed for patients suspected of having COVID-19.

Editor's Notes
- #80 Vapor plume migration refers to the migration of contaminants trapped in air bubbles in the vapor phase
- #95Â Operatories and sterilization areasâCounters, cabinets, and walls in these areas are contaminated routinely with oral aerosols, spatter, and smears composed of all types of oral contents, including small particles of hard and soft tissue, blood, saliva, crevicular fluid, and sometimes suppuration or pus. For many years, we have urged the disinfectant industry to provide robust disinfectants that would kill broad spectrum and quickly in the presence of such contaminants. This would allow clinicians to clean and kill simultaneously without exposing themselves to the viable microbes present immediately after patient treatments. Disinfectant brands capable of this have come and gone on the market, but all have been high ethyl alcohol (> 70% by volume) formulations
- #99Â . A study was performed on UV disinfecting of impressions and is part of the National Institutes of Health.
- #120Â action implemented by the worker or employer to reduce or minimize exposure to a hazard.
- #121Â types of administrative controls that include procedures for safe and proper work used to reduce the duration, frequency, or intensity of exposure to a hazard
- #122Â Very high exposure risk jobs -Workers in this category include: â Healthcare workers (e.g., doctors, nurses, dentists, paramedics, emergency medical technicians) performing aerosol-generating procedures Healthcare or laboratory personnel collecting or handling specimens from known or suspected COVID-19 patients High exposure risk jobs- Workers in this category include: â Healthcare delivery and support staff (e.g., doctors, nurses, and other hospital staff who must enter patientsâ rooms) exposed to known or suspected COVID-19 patients. â Medical transport workers (e.g., ambulance vehicle operators) Medium Exposure Risk -workers in this risk group may have frequent contact with travelers who may return from international locations with widespread COVID-19 transmission. In areas where there is ongoing community transmission, workers in this category may have contact with the general public (e.g., schools, high-population-density work environments, some high-volume retail settings). Lower Exposure Risk (Caution)Workers in this category have minimal occupational contact with the public and other coworkers
