Cleaning and high level disinfection are two distinct procedures  

required to reprocess the 3M

 True Definition Scanner wand for 

 

safe reuse. 

Step 3: Pre-Use Check

After disinfection and before using the 3M

 True Definition Scanner, we recommend a dental professional perform a 

visual check of the system. Look for cracks in the wand or cable, severe kinks in the cable, metal discoloration, corrosion 

or damage of any kind. Check to make sure the wand and lens are clean.

* High level disinfection validations were conducted for the 3M True Definition Scanner Wand using Cidex OPA, Dentasept Ultra and Metricide Plus 30. If these are not available, 

determine a compatible equivalent disinfectant based upon regulatory clearance (high level disinfectant), equivalent or higher active ingredient concentration and listed pH range.

Failure to adhere to the proper protocol listed in the steps above, may lead to improper disinfection and potential cross 

contamination hazards.

Step 1: Wand Cleaning

    Meets regulatory agencies’ requirements

1.  Use fresh gloves prior to unplugging and cleaning.

2.   Unplug the wand using the boot (textured portion) of the connector and loop the cord to make it portable. 
3.   Rinse wand surface under running tap water (~22°C/72°F) for one minute without getting cable strain relief or USB connector wet. 
4.   Wipe wand surface for thirty seconds with a soft, non-abrasive wipe wetted with an enzymatic detergent solution. 
5.  Discard wipe into biohazard waste. 
6.   Rinse wand under running tap water for one minute without getting cable strain relief or USB connector wet. 
7.   Dry with clean, non-abrasive, lint-free wipe and allow to dry completely. 
8.   Inspect wand for any visible contamination. If needed, repeat cleaning process.

Step 2: Wand Disinfecting

    Meets regulatory agencies’ requirements

1.   Immerse wand in an appropriate soaking container containing one of the high level disinfectants listed in the table below.

 

 

No CaviWipes. 

2.   Follow manufacturer’s instructions for use and label information for disinfectant used. Note prescribed soak times. 
3.   After soaking, rinse wand under running water for one minute. 
4.   Dry with clean, non-abrasive, lint-free wipe and allow to dry completely.
