Conclusion
Appreciation
Gratitude expressed to Dr. Ali Samba for the
invitation to share with colleagues the measures put
in place by the Head of department, Rev. Dr.
Matthew Boamah, DDNS Matron Essilfie and the
Dental management team to protect patients and
staff from COVID-19.
Initial measures to prevent the spread of
COVID-19
In March 2020, daily distribution of 500mg of vitamin C
to our staff using the ‘DOTS’ approach ( direct,
observed, treatment) was done.
The Department could not sustain this and encouraged
staff to purchase some on their own to help build their
immune system.
Educational talks commenced at the OPD.
Enforcement of routine protocols
All staff and patients observe the following:
Mandatory pre-screening and pre-triaging
Mandatory wearing of masks
Hand hygiene
Cough etiquette
Social distancing at the patient waiting areas (currently a
challenge at the department)
Strict disinfection measures in both clinical and patient
waiting areas.
Appropriate management of medical waste.
Enforcement of routine protocols cont’d
Barrier protection for all staff include:
Disposable vrs non-disposable working caps
Disposable surgical and N95 face masks
Disposable latex and surgical gloves
Protective goggles
Face shields
Wearing of Impermeable shoes
Working clothes such as scrubs, laboratory white coats,
disposable gowns and non-disposable surgical gowns
which are sent to the laundry at the end of the clinic and
subsequently to CSSD.
Measures employed to prevent spread of sars-
cov-2 virus in the clinic
The department currently has two teams: Team A
and Team B.
Team A alternates with team B on a weekly basis.
Our windows and doors are kept open for through
ventilation rather than using air conditioning which
circulates aerosol particles generated in the clinic.
Measures employed to prevent spread of sars-
cov-2 virus in the clinic cont’d
Manual devices such as hand scalers for caries
removal and periodontal scaling are used to minimize
the generation of aerosols.
A rubber dam kit has been procured to help
significantly minimize contaminated aerosols made up
of saliva and blood.
High-speed dental handpieces and ultrasonic devices
are used in addition to high and regular volume
suction.
Measures employed to prevent spread of sars-
cov-2 virus in the clinic cont’d
A special dental stand made of tempered glass
which protects the operating surgeon from
contaminated aerosols of the patient is currently
used in the periodontology area specialty.
Measures employed to prevent spread of
sars-cov-2 virus in the clinic cont’d
Our working environment is sprayed with
chlorine frequently after aerosol generating
procedures.
The surfaces are cleaned afterwards with a wet
chlorine towel.
The Department’s private cleaning services team
help with the disinfection of the dental clinic
which enables us work in a hygienic environment.
Measures employed to prevent spread of sars-
cov-2 virus in the clinic cont’d
The Dental clinic is disinfected biweekly (every
two weeks).
A schedule was drawn and approved by the Head
of the Environmental Health Unit.
The Department is sincerely grateful to Mr. Samuel
Ashley and his hard working team for supporting
this arrangement.
The use of mouthwashes at the Dental
department
Two mouthwashes are used at the Dental clinic with
special emphasis on one of them.
The use of 1% hydrogen peroxide or 0.2% povidine iodine
mouthwash and gargle as a preprocedural mouthwash for
1 minute is very effective and protects patients and staff
from becoming infected with the sars-cov-2 virus.
Patients’ wait for 3-5 minutes after use of the mouthwash
prior to commencement of the dental procedure.
Extra caution to protect the patient from being infected
by staff as well as staff infecting their relatives and other
close contacts is of much concern.
Hydrogen peroxide mouthwash
The use of 1% hydrogen peroxide mouthwash and
gargle is our preferred choice now in the
department.
0.5% hydrogen peroxide can also be used as nasal
lavage.
Prior to the use of the mouthwash, it is advisable
that a pre-mouth rinse with water to remove food
particles etc. from the mouth is carried out.
Hydrogen peroxide mouthwash
The hydrogen peroxide mouthwash currently sold
in most pharmacy shops has a concentration of
6%. Therefore, the mouthwash has to be diluted
appropriately to produce a 1% solution.
Kindly ask a Pharmacist for assistance when in
doubt with the concentration and dilution or one
can use the formula C
1
V
1
= C
2
V
2
Hydrogen peroxide mouthwash
Another approach to the dilution is to use 1 part
of hydrogen peroxide to 5 parts of
distilled/filtered water to obtain the 1% solution.
For example, if you take an aliquot of 10mls of
hydrogen peroxide, you will need 50mls of water
to obtain the 1% solution.
Hydrogen peroxide mouthwash
For patients who are ill, for example, those with
cardiovascular accidents (CVA’s) where gargling would be
dangerous from choking, one can use an absorbable foam
or cotton attached to a clean wooden stick to do oral
toileting gently after dipping the foam or cotton in a glass
of 1% or 1.5% Hydrogen Peroxide, 3 times a day.
Children below the age of 10 might find it difficult to
gargle with hydrogen peroxide and swallowing the
solution might cause gastric irritation.
Hydrogen peroxide mouthwash
Scientific evidence proves that hydrogen peroxide
inactivates respiratory viruses including the corona and
influenza viruses.
An article published by a team of Ghanaian medical
experts in the British Medical Journal on the 2
nd
of July
this year titled ‘
A case for hydrogen peroxide
mouthwash and gargle to limit SARS-COV-2
infection’
is available online.
Hydrogen peroxide mouthwash
The published article has been posted on the KBTH
‘What’s App’ platform and other platforms.
A monkey survey has also been deployed and posted on
most ‘What’s App’ platforms including the KBTH page.
Kindly fill one online if you have not done so already.
The clinical trials will begin soon spearheaded by the
team of Ghanaian medical experts.
Kindly participate fully in this research.
Testing of staff at the Dental department
All staff of the Department have not been tested so
far for the sars-cov -2 virus.
No staff has been ill or admitted for the disease to
the best of our knowledge in the department, should
some even be asymptomatic carriers.
The results of two colleagues I know who tested for
the virus turned-out negative.
The use of hydrogen peroxide mouthwash to prevent
COVID-19 has been adopted by the dental staff.
Conclusion
Dental surgeons are a high risk group in this
COVID-19 pandemic.
We are however used to most of the protocols in
place already and have just reinforced them.
The Dental management team is however
working at updating the current protocols in
place.
Thank you for your attention
.
