Introduction
Q1
The Coronavirus Disease 2019 (COVID-19) epidemic began in
Wuhan, China, in December 2019.
1
On January 1st, 2020,
WHO announced that this outbreak represents an interna-
tional public health emergency, affecting 2,725,920 people
by April 24, 2020, causing, 191,061 deaths.
2
On February 11,
The International Committee on Taxonomy of Viruses has
made public the name of the virus causing COVID-19: severe
acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
3
Transmission paths
The two modes of transmission are via aerosols, through
drops of fluid spread by coughing, sneezing, and fecal-oral
(digestive).
1
Characteristics of COVID-19
The incubation period is 1e14 days, most commonly 3e7
days. Patients are contagious in the latency period. On
average, a patient can infect another 2e2.5 people.
4
The main symptoms are represented by:
Fever
Cough (especially dry)
Fatigue
Sputum
Shortness of breath
Dry throat
Headache
Digestive manifestations in a small percentage of
patients
1
The fraction of severe, critical cases and mortality rate
is higher, compared to influenza. The number of deaths per
day relative to the total number of cases gives us a per-
centage of 3e4%.
4
Control of infection in oral healthcare settings
In light of the thread of COVID-19 pandemic, the conception
of strict and efficient protocols for oral healthcare settings
is of paramount importance. This specialty is prone to cross
infection among patients and healthcare workers. This
article provides recommendation on patient evaluation,
treatment approach for dental emergencies and infection
control protocols.
Screening for COVID-19 status and triaging for
dental treatments
During the pandemic, it is recommended to perform
exclusively emergency dental procedures to protect the
medical personnel, the patients and to reduce as much as
possible the consumption of personal protective equip-
ment. Patients’ general health assessment before dental

treatment is very important (Fig. 1), as dental health
workers can identify undiagnosed COVID-19 patients.
Emergency dental patients that test positive for SARS-CoV-2
should be referred for emergency care where appropriate
Transmission-Based Precautions are available. The indica-
tion for SARS convalescing patients was to postpone dental
treatments for 1 month.

Same recommendation could be
adopted for COVID-19 patients.

What is considered an emergency in dentistry, according
to ADA?
Dental emergencies are those that put the patient’s life
at risk and require immediate treatment to stop bleeding,
reduce pain and stop infection. The emergency dental
cases are represented by:
Severe pain of pulp origin
Pericoronaritis, pain in the third molar region
Postoperative osteitis, dry alveolitis
Dental fractures causing pain or soft-tissue injuries
caused by trauma
Luxations, dental avulsions
Dental treatments required before general medical
procedures
Final cementation of crowns, decks if provisional resto-
ration is lost, deteriorated or causes gum irritation
Biopsies
Other emergencies shall be considered as follows:
Extended cavities or damaged restorations causing pain
(Temporary restorations are performed)
Suppression of suture threads
Dental treatments of oncology patients
Dental adjustments when function is impaired
Change of temporary fillings in endodontic access cav-
ities, if they have caused pain
Adjustment of the orthodontic apparatus if it has caused
pain or ulceration on the oral mucosa.
8
Assessment of the gravity of the dental emergency is
very important. The evaluation of the dental and general
health status of the patient is based on the workflow in
Fig. 1. Dental practitioners should aim to ease patients
suffering and alleviate the burden that dental emergencies
would place on hospital emergency departments.
Effective control of infection in the dental office
Social distancing protocol for patients should be adopted in
the dental office. Appointments should be scheduled apart
to minimize contact between patients. If this standard is
not applicable, patients can wait in their personal vehicle,
until it is their turn.
Since the main route of transmission of the virus is the
aerial one, it is necessary to use personal protective
equipment, gloves, face masks (N-95 or FFP2), goggles or
facial shield to protect the skin and mucous membranes of
the medical personnel as well as waterproof robes, jump-
suits. If the mask is damaged, or the doctor has difficulties
breathing, the mask should be changed. Dental health
worker should have a seasonal flu vaccine this year, ill-
health status of medical personnel has to be assessed daily.
Rigorous hand hygiene and surfaces in the dental office is
the most important measure of reducing the transmission of
microorganisms to patients. Depending on surface type,
temperature, humidity, SARS-CoV-2 may persist on surfaces
from a few hours to a few days. All reading materials, mag-
azines and toys should be removed from the dental office.
To minimize the formation of drops and aerosols, it is
recommended to perform minimally invasive procedures,
to use the surgical vacuum cleaner, 4-hand work, and rub-
ber dam isolation of the operator field. Before dental pro-
cedures it is recommended that the patient rinses with
antimicrobial oral solutions.
9
Resorbable sutures after sur-
gical procedures are recommended. Aerosol generating
procedures should be scheduled at the end of the program.

If procedures were performed without N95 masks, both the
healthcare provider and the patient are at moderate risk
for SARS-CoV-2 infection/transmission. Fourteen days of
quarantine are recommended after this exposure. As
intraoral x-ray can induce saliva secretion and coughing,
10
extraoral radiographies (panoramic, Cone Beam Computer
Tomography) are alternatives.
After providing dental care, facial protective equipment
should be cleaned and disinfected. The X-ray equipment,
the light and the dental chair should be disinfected ac-
cording to the instructions of the manufacturer. The floors
should also be disinfected. Handpieces must be sterilized
after each patient. Frequently used surfaces such as: door
handles, bathrooms, desks must be disinfected often.
In the areas severely affected by COVID-19, the patients
arriving in the waiting room should receive protective
masks.

Conclusion
The COVID-19 pandemic represents a global challenge,
given the increased contagiousness of SARS-CoV-2,
dental healthcare providers have to adopt new pro-
tocols for a better infection prevention in the dental
office and new working protocols aimed to prevent
spreading the virus.
