Oral Health Standard Operating Procedure 1 version 4
1.1 STANDARD PRECAUTIONS
PURPOSE
Standard precautions are applied as a first-line approach to infection control. These form the basis for your decisionmaking and practice. Standard precautions are a set of guidelines based on the assumption that all blood and body
fluids are potentially infectious. In the context of sterilizing practice and the Standard Operating Procedures,
standard precautions include:
Hand Hygiene
Examples of when hands should be cleaned
 When first arrive at workplace/clinic
 Before and after commencing a procedure
 After handling equipment / instruments soiled with blood or body fluids
 After direct contact with blood or body secretions
 After cleaning the environment
 When you move from a dirty area (such as the instrument cleaning area) to a clean area (such as the
sterilizing area)
 After the removal of Personal Protective Equipment (gloves, gown, face shields etc)
 When you go to have something to eat or drink
 After you have gone to the toilet and again upon re-entering the clinical area
 After coughing, sneezing or wiping your nose
 At end of the shift immediately before leaving the workplace
Personal Protective Equipment (PPE)
Is to be worn to protect the healthcare worker and patients as this minimises the risk of infection transmission when
having contact with blood and body fluids. PPE must be removed when leaving the cleaning area and replaced with
fresh items on returning. At a minimum a single use disposable plastic apron or other fluid resistant gown shall be
worn over clinical gowns each time instrument reprocessing is undertaken. This plastic apron must be removed and
disposed of before resuming patient care activities in the clinical area and when accessing items in clean/ sterile
storage areas.
Gloves
Heavy duty gloves are to be worn when handling items for cleaning. The allocation of heavy duty gloves shall be one
pair for one person for one day, unless damaged or grossly soiled
 Single use gloves are to be changed after use
 Appropriate gloves as recommended by the manufacturer are to be worn when handling enzymatic cleaners
and acid based agents/chemicals
Face Shields or Safety Glasses and Masks
 Safety glasses and face shields are multi-use and must be cleaned, after each use, with detergent and water
 The mask must cover the mouth and nose completely and be tied, so that there is no gaping at the side of
the mask
 Masks are worn once and then discarded
 Remove the mask by undoing the ties; and avoid touching the front of the mask
Fluid Resistant Gowns/Aprons
 Long sleeved fluid resistant gowns/aprons and protective sleeves are to be used if there is a possibility of
clothes or skin becoming wet or contaminated with blood or body fluids e.g. when cleaning contaminated
instruments
 If, for some reason, your clothes become soiled with blood or body fluids, you must wash the area on your
body soiled and replace your clothes. In some circumstances, you may need to have a shower
Occupational Health & Safety requirements
 Fully enclosed waterproof non-slip shoes should be worn
 Clean clothing attire as per units protocol
 Hair pulled back neatly with hair and beards covered during instrument reprocessing procedures
 Short nails
 Wearing of jewellery, nail polish and artificial nails as per local policy
 Cuts and skin abrasions are covered with a waterproof dressing and should be examined by a medical
practitioner before commencement/returning to work in the reprocessing area. (Check local policy & HR)
 Hearing protection when using high pressure equipment e.g. air guns
 Report incidents/accidents to Senior Dental Assistant and complete the relevant documentation

1.2 SOILED PICKUP COLLECTION
PURPOSE
Soiled pickup collection refers to the collection of used dental instruments and equipment. There are various scenarios
that the following principles apply to aim to minimise damage to instruments and prevent the cross contamination of
clean and sterile items.
These scenarios include:
 Pickup of soiled instruments at dedicated scheduled times and transferred/transported to a separate instrument
reprocessing area/site
 Where staff are required to transfer used instruments after each patient appointment, to a reprocessing area.
Refer to SOP 1.4 Chemical and detergent mixtures
Refer to SOP 1.6 Manual Cleaning for immersible items- For those items that are unable to be cleaned using a
washer disinfector or ultrasonic cleaner
Refer to SOP 1.7 Manual Cleaning for non-immersible items – For those items that are unable to be submerged
under water
Refer to SOP 1.8 Ultrasonic Cleaners
OPERATING PROCEDURE
 Application of standard precautions
 Trolley/container to be used for this purpose should be dedicated, enclosed and with solid bottom shelving and
labelled appropriately e.g. contaminated
 Instrument sets are to be kept together and not mixed. Visible soils (e.g. blood, body fluid, filling materials) are to
be removed chair-side by methods such as damp or dry wiping during and after the procedure
 In order to prevent soil from drying on instruments, other products such as pre-cleaning solutions may be
appropriate. To avoid damage and potential for sharps injury single loose items must be secured prior to being
placed into the transport container
 Plastic containers for transportation are to be leak proof and puncture resistant with sealable lids and be labelled
for user area identification
 To prevent instruments from being damaged do not place heavy instruments on light instruments
 The composition of instrument transport containers and the method of transportation will vary greatly from
District to District. It is highly recommended that an Occupation Health and Safety Risk Assessment be
undertaken locally to identify risks and implement control measures that will minimise the risk to staff of
sustaining an injury. Changes to the schedules will be through Management and communicated to all staff
involved
 Do not over load trolleys/containers
 Follow a dedicated route
 Do not leave unsecured trolleys/containers unattended in corridors. Contaminated instrument containers must be
stored in a dedicated secured area away from public access
 Report immediately to Senior Dental Assistant if there are any issues
Occupational Health & Safety requirements
 There is to be no lifting above shoulder height

Version 4: November 2012
1.3 SORTING PRIOR TO CLEANING
PURPOSE
On receipt into the cleaning area, items should be sorted according to type, checked for completeness or defects
and sorted into the method of cleaning to allow the staff member to follow through to user area promptly.
OPERATING PROCEDURE 
 Application of standard precautions
 Care must be taken when trying to retrieve instruments from trays or containers as a sharps injury could
occur, ensure you can see what you are retrieving
 Check if items are to be priority processed and process accordingly
 Perform a visual check of instruments for damage and to ensure instrument sets are complete
 Instruments are to be cleaned and sterilized prior to being sent for repairs. NB: check with manufacturer of
instrument prior to cleaning and sterilizing items for repairs as some items may be further damaged by
these process
 Do not throw anything out, if unsure, check with the Senior Dental Assistant
 Check manuals if unsure of cleaning process. If still unsure, check with Senior Dental Assistant (do not
guess)
 Instruments not belonging to the oral health facility (e.g. loan instruments or visiting dentists with private
equipment), are to be checked, multi-part instruments dismantled, labelled and undergo a cleaning
process prior to packaging and sterilization
Report immediately the following issues as they arise
 Immediately report any sharps such as blades, needles or broken glass left in containers. Report to the
Senior Dental Assistant and document on relevant incident report e.g. near miss occupational exposure or
workplace health and safety incident
 If instrument parts are missing follow facility procedure and report immediately to the Senior Dental
Assistant
 Report any damaged or broken instruments to the Senior Dental Assistant
 Report heavily soiled items from user areas to the Senior Dental Assistant (items should have gross blood
and debris removed immediately following a procedure and prior to returning the item to CSD for
processing)
 Do not reprocess ‘single use only’ items, report to the Senior Dental Assistant if this does occur
 Non-compliance to processes
CLEANING PROCESS:
Sort items according to cleaning process as per manufacturers instructions:
 Manual cleaning
 Cannulated/lumened items
o Not able to be immersed in water e.g. dental handpieces
o Able to be immersed in water e.g. Amalgam carrier
 Items requiring lubrication
 Mechanical cleaning

Version 4: November 2012
1.4 CHEMICAL & DETERGENT MIXTURES
PURPOSE
Breaking down and removal of blood, proteins and debris during washing stage can be achieved manually or
mechanically .Prior to the purchase of cleaning solutions consideration needs to be given to the chemicals
compatibility with the dental device, intended cleaning process and the chemicals storage requirements.
Manual Wash
Properties: Mild alkaline instrument detergent
pH range: 8.0-10.8
Low foaming properties
Non-corrosive
Non-toxic
Non-abrasive
Free rinsing
Bio-degradable
Preferably liquid
Use and rate of concentration: as per manufacturers
instructions
Mechanical Wash
Properties: Alkaline instrument detergent or as per
mechanical washer manufacturers instructions
pH range: 8.0-11.5
Biodegradable
Nonabrasive
Low foaming
Free rinsing
Preferably liquid
Use and rate of concentration: As per manufacturers
instructions, automatic dispensing system is
preferred
Enzymatic Cleaners
Includes enzyme pre cleaners and enzymatic
detergents
Breaks down proteinaceous matter
Approved by the instrument manufacturer
Specific PPE may be required
Used as per manufacturers instructions i.e.
Dilution if required, solution temperature, application
time and product used within expiry date
Used on items when blood or debris has dried or
hardened
Lubricant
Must be water miscible and compatible with instrument
and sterilizing agent
Hand hygiene liquid
Approved for use by Infection Control
Hand Cream
Moisturiser and barrier cream should not be applied in
the reprocessing area as they can effect the penetration
of the sterilant/steam and compromise the wrapping
materials. They must be approved for use by Infection
Control
Steel Coat
Stainless steel cleaner: used on the outside of
machines as per manufacturers instructions (stainless
steel only)
Clean cloth used for application and dry clean cloth
used for polishing
Environment Cleaner for reprocessing area
Select product as per manual cleaning solution
After cleaning ensure cleaner is rinsed off thoroughly
and dry area with disposable low-lint cloth
Drying Agents (Rinse Aids)
Drying agents are used in washer/disinfectors and are
surfactants that “wet” the final rinse water, allowing the
water to spread evenly over a surface instead of
beading. The even spread of water allows flash drying
to take place, reducing the build-up of hard water salts
on the surface of the instrument, whereas beaded water
will dry, leaving concentration of mineral salts. Most
drying agents are not as effective on plastics as they are
on metal objects. Load instruments and metals on top
racks with plastics on the bottom rack. Place items that
may have “lips” on their edge so that water does not
pool.
Acid Base Agents
Use: Only used on stainless steel surfaces for
intermittently descaling or destaining
Follow chemical manufacturers instructions,
Handling and Storage of Chemicals
including safety precautions, dilution and instrument
As per manufacturers instructions and Safety Data
compatibility
Sheets and in accordance with CHEM Alert and the
Rubber or nitrile gloves are to be worn when
facilities Workplace Health and Safety instructions.
handling acid based agents
Dissimilar instruments should not be processed at
the same time
Mix the agent as per manufacturers instructions
Only mix when required and discard at the end of the
day

Version 4: November 2012
1.5 PRE CLEANING
PURPOSE
Pre cleaning (initial cleaning) allows for the removal of visible blood, body fluids and debris from items prior to
cleaning (definitive cleaning). Pre cleaning shall be undertaken as soon as possible (e.g. during and post
procedure chair-side).If blood, proteins and other debris are allowed to dry or remain in crevices and joints, the
instruments become very difficult to clean and are prone to stiffness and accelerated corrosion.
Refer to SOP 1.6 Manual Cleaning for Immersible Items. For those items that are unable to be cleaned
using a washer disinfector or ultrasonic cleaner
Refer to SOP 1.7 Manual Cleaning for Non-Immersible Items. For those items that are unable to be
submerged under water
Refer to SOP 1.8 Ultrasonic Cleaners
OPERATING PROCEDURE
 Application of standard precautions
 Pre cleaning can be performed by methods such as dry wiping, damp wiping or use of a commercially
available single use only instrument sponge
 Place the dry wipe, damp wipe or sponge on the bracket table and carefully wipe the instrument across
the material.

1.9 WASHER DISINFECTORS
PURPOSE
Automated washer disinfector machines clean and remove bio burden/micro-organisms (blood and debris) that
adhere to contaminated items. The use of washer disinfector machines reduces the manual handling of
contaminated items and is the preferred and verifiable process. Various types and sizes are available and must
be equipped with a cycle record. Thermal disinfection is the inactivation of non-sporing organisms using heat and
water. This occurs during the final rinse stage where time at temperature is achieved.
OPERATING PROCEDURE 
 Application of standard precautions
 Refer to SOP 5.4 Mechanical Washer Cycle Monitoring
 Follow the manufacturers instructions for cleaning, maintenance and correct operation. Refer to SOP 5.9
Routine Cleaning of Reprocessing Equipment

 Choose the specific washer insert that is required e.g. dental handpieces and follow manufacturers
instructions (not all Dental Handpieces are recommended to be cleaned through a Washer Disinfector)
 Check that instruments/equipment have been disassembled, unlocked, opened (e.g. forceps, needle
holders, scissors)
 Disks or tags may be used to identify instrument trays when they are placed into multiple baskets for
cleaning
 Instrument trays sets are not to be loaded beyond the operators capacity to lift comfortably. Operators
should also consider capacity of others that may be required to lift the load.
 Ensure all instrument trays and parts of disassembled instruments are correct and together and placed
into specific basket as per process validated at commissioning
 Load the baskets/racks ensuring they are not overcrowded or over opened so that water and chemical
contact will reach all internal and external surfaces
 Small/light items to be placed in the appropriate lidded basket with hold down catch to ensure they do
not become loose in the machine during operation
 Use a hold down screen as the pressure of water inside the machine can dislodge items
 Hollowware is loaded in a draining position to prevent retention of water, cleaning solution and ability to
dry
 Minimise lifting of racks
 Make sure equipment stays in the perimeter of the rack
 Select the appropriate cycle for the load
Lumen Instruments
 If the machine has the capability of cleaning cannulated/lumened instruments and handpieces, attach
the instrument to the appropriate size port
Washer Disinfector Cycles
 A variety of cycles are available
 Ensure correct cycle for your load is selected
 If Barcode system is available - make sure barcode or electronic eye is inserted on the side of the rack
and the code corresponds with the material to be loaded allowing cycle parameters to be met for that
material
Version 4: November 2012
1.9 WASHER DISINFECTORS
Releasing the Load and Unloading the Washer Disinfector
 Check cycle parameters have been met and print out/log (or equivalent) is signed
 Care is taken when opening the doors and unloading as there may be residual heat and moisture in
the machine
 Inspect load to ensure that items have not become dislodged or displaced
 When unloading baskets avoid conditions that may damage the equipment/instruments and that may
injure staff
 Perform a preliminary check for cleanliness of items and any that appear dirty or stained are returned
to the cleaning area for recleaning/destaining
 If the machine does not have the ability to dry the load, unload items and place into drying cabinet
 Industrial dry and oil free compressed air should be used to remove excess moisture from
cannulated/lumen instruments prior to placing in drying cabinet
 When dry, place instruments onto designated work benches to await packing/wrapping
Workplace Health and Safety Considerations
 Equipment will be hot, wear/use operator hand protection eg. Heat/sharp resistant gloves
 Do not lift heavy washer disinfector baskets, washer disinfector carts shall be available for use
 Observe for pooling of hot water in bowls or trays
 Use manual handling principals to minimise injury
 Wear ear protection if using air pressure gun
Report Immediately
 Cycle parameters not meeting set requirements or variations to cycle parameters – failed cycles

1.10 DE-STAINING
PURPOSE
To remove stains that can contribute to corrosion, pitting or other damage to dental devices during the
inspection of instruments. Instruments that are heated during procedures i.e. endodontics, are prone to
developing carbon deposits and should be de-stained as necessary.
OPERATING PROCEDURE
Ensure the de-staining solution is compatible with the dental device. Usually only used on stainless steel
instruments unless otherwise indicated by the manufacturer.
 Application of standard precautions
 Wear protective clothing including heavy duty gloves compatible with the de-staining chemical
 Use a container with a good fitting lid
 Strictly follow manufacturer’s instructions on water / chemical ratio
 Dissimilar instruments should not be processed at the same time
 Follow the manufacturers recommendations for exposure of the item to the de-staining chemical
 Instruments heated during procedures (i.e. endodontic treatment) may require de-staining periodically.
 Do not exceed recommended time of exposure to the chemical
 Remove items from chemical mixture using appropriate type gloves suitable for the chemical to lower
the risk of injury e.g. acid bath and enzymatic cleaners
 After exposure the item is required to be re-washed to remove chemical residue
 Only mix de-staining solution when required and dispose of according to manufacturers instructions
after use
 Remove gloves and wash hands
 Identify and report any patterns of staining occurrence to enable investigation of possible causes

 Do not overload drying baskets
 When loading new items for dry where items are already in dryer, place existing items on upper shelves,
new items on lower shelves to eliminate drips onto dry items.
UNLOADING
 Cabinet temperature operates within a range according to manufacturer’s instructions and a visual
check to confirm temperature range prior to unloading is undertaken
 Drying times should not exceed 1 hour
 Heat resistant/sharp resistant gloves should be worn to unload items
 Remove items on a regular basis
 Avoid leaving items in the dryer too long
 Assess items are dry before removing
 If the dryer temperature is not within the manufacturers specifications report immediately to the Senior
Dental Assistant
 Care must be taken when trying to retrieve an instrument from a tray of instruments as a sharps injury
could occur (ensure you can see what you are retrieving) and items may be hot.
Workplace Health and Safety Considerations
 Items may be hot and sharp, use appropriate personal protective equipment
 Wear ear protection if using air pressure gun
 Use manual handling principle to minimise injury
