NEED HELP ?
During this pandemic most practices would have experienced significant downtimes and closures. You can Rely on Us to assist you get back up and running safely. It is highly recommended to return to work at least a week prior to opening as there are several health risks and issues you want to avoid before seeing your first patient again. Many items within the dental clinic have moving parts and running water through them. Due to the period of stagnation there is significant health risks of biofilm* contaminated waterlines. It’s imperative, all dental chair waterlines are assessed prior to opening using an appropriate HCP water test system I.E. HS code ST-9MERHPCSAMP. If you are not intending to re-start your practice – we suggest that you put into place a process of running through the decommission and recommission process on a maximum 4 week cycle. Production equipment that handles fluids whether air/water/treatment fluids/oils are designed for constant use, extended storage may have unexpected consequences. The process of cleaning, then running the equipment periodically will articulate/lubricate/actuate the various components. Our view is this use and testing will to help identify any deterioration of function that can be addressed in a timely manner. Also consider when you first arrive disinfecting (using suction cleaning solution) your practice sinks. Reducing the flora and fauna growing in the ‘S Bend’ may reduce the aerosol contaminates from the traps under the sinks, (although this is a difficult to quantify phenomenon). This simple step may reduce non-specific odours and contamination.
*To appropriately assess your waterline quality, you must allow 7 days for a test to show the accurate CFU count. This time is required to allow valid test results and allow time to perform a shock treatment prior to seeing your first patient.

Turn on all main power supplies to the clinic I.E. A/C, plant room Ensure that all clinical and sterilisation areas are cleaned as per the ADA guidelines Ensure that all bottle-fed treatment centres are refilled with water and flushed multiple times* Ensure that all treatment centres that are plumbed to town water, that the main tap supply at services is turned back on and dental unit is flushed multiple times* 5. If a central filtration system is used please ensure the filter is flushed through via bypass valve or similar 6. Once the lines have been thoroughly flushed you will need to test your waterlines to ensure the CFU count is within the legal drinking limits of <500CFU or <200CFU for immune compromised patients I.E. HS code ST-9MERHPCSAMP 7. For instructions and information on dental unit waterline testing, shock treatments and maintenance please refer to the Henry Schein waterline webinars for more information 8. Ensure all computers are turned on and possible software updates are recognized and loaded 9. Review all clinical surfaces are clutter free and cleaned/disinfected 10. Ensure that sterilisation/ surgery equipment is switched on and operational When recommissioning equipment such as chairs that produce aerosol, please be mindful of potential biofilm organisms spread by aerosol, this may affect nearby surfaces including your health. Potential management may include purging into a narrow-necked container using an HVE to create a negative pressure and PPE along with post purge surface cleaning.
*If you have the competency to do so you may choose to remove handpiece couplings, motors etc from the tubing before the first flush to allow an unimpeded flow in essence allowing a clean exit of any potential suspended materials away from the intricate water paths in these devices. After the initial purge they can be refitted for subsequent purges and ready for clinical use. If you are unsure how to remove, please leave them in place, rather than risk damage from unfamiliar processes.
Use disposable cloths or paper roll or disposable mop heads, to clean and disinfect all hard surfaces or floor or chairs or door handles or reusable non-invasive care equipment or sanitary fittings in the room, following one of the 2 options below: 1. Use either a combined detergent disinfectant solution 2. Or a neutral purpose detergent followed by disinfection 3. Follow manufacturerâ&#x20AC;&#x2122;s instructions for dilution, application and contact times for all detergents and disinfectants 4. Any cloths and mop heads used must be disposed of as single use items
You may want to regularly test all equipment items in your practice, to ensure functionally and to prevent possible â&#x20AC;&#x2DC;seizingâ&#x20AC;&#x2122; of items. If this is done, the above process should be undertaken each time, especially if water and solution are run through the treatment centre, dental unit water lines and/or vacuum system.
Note: The suggested broad guidelines are of general nature. If more specific questions are to be answered, please contact your usual supplier and their respective specialists or service support.

If your autoclave or disinfector units are supplied with water from a central RO water treatment system, the following procedure (depending on brand and system) should be considered; 1. Turn on main supply valve to RO System 2. Switch on power supply to RO system 3. Flushing of system is necessary to remove any possible biofilm left while being in hibernation. This is achieved in many ways and please ensure you check with User manual for proper procedure. In many systems, an automated flushing may be initiated via switch on the user interface. Please ensure a minimum of five minutes of water cleaning is run before normal operation is put in place
4. Following the flushing it is advantageous to ensure the autoclave water quality control* is within limits as per user manual. Alternatively, please used a TDS water meter (Total Dissolved Solids) is used on a water sample. Results should be < 10 TDS (PPM). For the disinfector, water quality should be < 20 TDS (PPM)**
*Not all autoclaves have an internal water quality meter **Depending on brand – consult you User Manual

Disinfectors (all brands) are using various detergents. All pumps and supply lines must be refilled after an extended period of no use. Before a re-start, please refer to manufacturer’s operator manuals. The main objective will always to refill the detergents (replenish salts if required) and a general procedure will be as follows; 1. 2. 3. 4. 5.
Reconnect disinfector to power supply Switch on disinfector and check all date and general settings on user interface (GUI) Ensure wastewater line is connected to drain Return racks, trolley and inserts to disinfector chamber As detergents may be caustic and very alkaline, ensure suitable PPE is secured before the next steps 6. Locate detergent bottles and relocate suction devices inside. Ensure the right suction hose is attached to appropriate type of detergents 7. Check salt supply and refill if required 8. There might be a detergent refill program available in your disinfector - please check and use if available 9. If no refill procedure is available, initiate and run a normal and preferred standard cycle with an empty chamber. During such cycle detergent lines and pumps will be refilled – wait until cycle has concluded. Open chamber and ensure racks are in correct position, the rotation of the cleaning arms is in order and that door seal is tight and no leaks observed 10. If a Soil Test” is part of your standard procedure, please prepare same and run another cycle 11. Following the second cycle, check soil test strip and if accepted - your disinfector is ready for use – if NOT, please call your service provider
If the milling unit indicates when turned on to proceed to the cleaning process, please follow the guidelines for cleaning. Otherwise fill the tank with water and appropriate cooling liquid. If indicated leave the milling chamber door open until use. Printers make sure all resin has been replaced and tested prior to use.

Clean suction filters and disinfect suction system, lubricating O-rings and seals. Allow the suction to run on for a few minutes to dry out the chairs suction system and ducts. Waterlines, the primary goal is to either dry out the unit or place a hibernation solution like Bilpron (if supported by chair maker) to prevent stagnation/biofilm creation and corrosion/deterioration of working components.
First step is to conduct long purge of waterlines, if you have the means conducting a Biofilm Removal process the cleaner it is the better. The next step is to dry out the unit, if you’ve a bottle, connect it empty and run the all the instruments with water and cupfiller / spittoon until the unit runs dry. Or Purge with a hibernation solution like Bilpron and switch unit off with once the waterlines are filled with the solution Or For mains connected units without bottle, contact a service person to disconnect and dry out the using compressed air through the water system. Please be thorough; the last step before you switch off the lights is the final clean water and micro fibre cloth wipe down before you close the door. Equipment, benches, floors and office fittings totally dry and clean of bioburden, disinfected and removed of all disinfection and cleaning chemical residues is your best protection strategy. Please resist bombing the practices with ‘chemicals’ and closing the door on wet gear will do harm and not achieve what the idea proposes.
