This guidance is based on what is currently known about the transmission and severity of coronavirus disease 2019 (COVID-19) and the implications for dental practice. The California Department of Public Health (CDPH) will update this guidance as additional information becomes available.
This document aims to provide guidance for resuming deferred and preventive dental care. It builds on the April 27, 2020, State of California Guidance, Resuming California’s Deferred and Preventive Health Care regarding prioritization and delivery of dental services. It is important to continue to monitor COVID-19, including case counts and hospitalizations and their impact on the health care delivery system.
To track trends in prevalent COVID-19 cases, deaths, new cases, hospitalization, and testing results, please visit the new data portal at COVID-19 Statewide Update. Many local health departments are also publishing community level data that may be helpful to your practice for assessing pandemic conditions in your community.
According to the Occupational Safety and Health Administration’s (OSHA) Guidance on Preparing Workplaces for COVID-19, dental health care personnel (DHCP) are in the very high-risk category for exposure to SARS-CoV-2 virus that causes COVID-19 when they are performing certain aerosol generating procedures. This risk requires a level of heightened awareness, training, preparation, and adherence to a combination of standard and transmission-based precautions as appropriate to ensure the safe provision of care. Employers of DHCP are also responsible for following applicable OSHA requirements, which in California include Cal/OSHA's Bloodborne Pathogens, Personal Protective Equipment, and Respiratory Protection standards. To address asymptomatic and pre-symptomatic transmission, dental offices should implement source control (i.e., require facemasks or cloth face coverings) for everyone entering the dental setting (dental healthcare personnel and patients), regardless of whether they have COVID-19 symptoms.
Patients with active COVID-19 infection should not receive dental treatment in a dental office. Dentists and medical providers should work together to determine an appropriate facility for treatment. Procedures on patients with COVID-19 should be carried out in accordance with Cal/OSHA’s Aerosol Transmissible Diseases (ATD) Standard.
The following guidelines were developed to assist dental practitioners to resume clinically necessary dental care for previously scheduled procedures or for those non-COVID patients who are likely to develop dental emergencies with the following considerations:
According to CDC, multiple symptoms may appear 2-14 days after exposure to the virus. Therefore, the screening should include an assessment of:
The CDC Interim Infection Prevention and Control Guidance for Dental Settings During the COVID-19 Response provides essential guidance for resuming selected dental services and developing a protocol for dental treatment during the pandemic. The American Dental Association (ADA) recently published the Return to Work Interim Guidance Toolkit that contains many useful resources and the California Dental Association has established “Back-to-Practice” resources for California, including checklists for reopening dental offices and communicating with patients on resuming dental care, COVID-19 screening tools for both employees and patients, and checklists for needed protocols, supplies and equipment. These resources may be useful when implementing these recommendations. The following recommendations are provided to supplement the CDC Interim Guidance:
Updating the office Injury and Illness Prevention Program including a written procedure for screening patients for COVID-19 that is consistent with current guidelines issued by the Centers for Disease Control and Prevention (CDC) for infection control in dental settings. For more information visit the Guidance from CDC for infection control practices in dental settings. Patients must be actively screened on the spot for fever and symptoms of COVID-19 before they enter the dental setting in addition to screening when an appointment is set up.
Developing a Respiratory Protection Program as required by Cal/OSHA Section 5144; see CDA practice support webpage.
Ensuring that employees have been trained in the screening procedure in accordance with Section 3203 Injury and Illness Prevention Program. For a template, see CDA practice support webpage.
The CDC Interim Infection Prevention and Control Guidance for Dental Settings During the COVID-19 Response describes the elements for developing a protocol for providing dental care during this time. A critical aspect of this is to avoid aerosol generating procedures whenever possible. If aerosol generating procedures are necessary, employ aerosol management tools that may consist of the use of four-handed dentistry techniques, high evacuation suction, dental dams, or other appropriate equipment to minimize or capture spatter and aerosols. Respiratory protection should be worn to protect against infectious aerosols emitted during procedures on asymptomatic patients, since most dental procedures have the potential to generate aerosols. A fit-tested surgical N95 respirator offers respiratory protection with fluid resistance and should be worn under a full-face shield for eye and face protection. If surgical N95 respirators are not available due to supply shortages, an FDA-cleared surgical mask should be worn under a full-face shield. Because a surgical mask is not tightly fitted to the face, it will not provide protection against inhalation of small potentially infectious aerosols although it will block spatter from reaching the nose and mouth of the wearer. Information on implementing a respiratory protection program.
At a minimum, dental practitioners must follow the CDC recommendations for:
Source control: DHCP should wear a facemask at all times while they are in the dental setting;
PPE use during clinical care including training and demonstration of understanding of PPE use, respirator or surgical mask, face shield, eye protection, gloves, and gowns;
Screening and monitoring of DHCP; and
For details regarding the above mentioned topics, see the CDC Interim Infection Prevention and Control Guidance for Dental Settings During the COVID-19 Response.
During the pandemic, dental providers should regularly check their local health department website for information and important updates about COVID-19. Additionally, the California COVID-19 Statewide Case Statistics dashboard has case information by county, and dental providers should access this information regularly so they are aware early on should transmissions start to rise in their community.
During disruptions of the supply chain, please request supplies through your local Medical and Health Operational Area Coordinator (MHOAC). Please keep in mind that requests for supplies will need to be granted on a priority basis.
