Frequently Asked Questions

What are the recommended standards for dental unit water quality?

According to the ADA, CDC, and EPA, the number of bacteria in water used for non-surgical dental procedures should be as low as reasonably achievable and no higher than 500 CFU/mL.

How do I know if I need to clean my waterlines?

Even new waterlines begin to grow bacteria within a few days of use. Any waterline that has not been cleaned routinely will have a high chance of being above the 500 CFU limit set for potable drinking water. There are several types of tests available to determine the level of colony forming units (CFU) in the waterline.

Which DentaPure product is right for my unit?

Independent reservoir (bottle) units: DP40B (two months) or DP365B (one full year). Municipal or well (direct feed) units: DP90M (three months) or DP365M (one full year).

Should I clean my lines before installing DentaPure?

“Shocking” is not required before the first use of DentaPure. For maximum biological reduction, it is suggested that the waterlines are cleaned using an approved dental unit waterline agent prior to installation of DentaPure cartridges.

Does DentaPure remove biofilm?

DentaPure does not claim to remove biofilm; however, DentaPure does prevent the growth of additional biofilm. To remove biofilm, DentaPure recommends an approved dental unit waterline cleaning agent to be used before installation of DentaPure cartridges. When used as directed, DentaPure reduces bacteria in the waterlines to a level that will meet or exceed the ADA recommendations for water quality.

Does the iodine have a taste?

Yes, however most patients cannot detect the low levels of iodine (2-4 ppm). Those that do describe it as having a slight “medicine” aftertaste. Proper flushing in the morning (2 minutes) and between patients (30 seconds) will keep the taste to a minimum.

We just installed DentaPure, why is our water discolored or have an odor?

Once installed DentaPure will quickly kill the bacteria that is inside the line, this causes a phenomenon known as “bio-burn”. Flushing two liters of water through the dental unit waterlines can alleviate this; the color and odor should dissipate. Multiple two-liter flushes may be necessary.

What about my patients with iodine allergies?

DentaPure cartridges use pure, elemental iodine (I2). No allergy-causing proteins are attached to the iodine, eliminating the possibility of an allergenic response. There are no restrictions on use for any patient. Feel free to download and print the Patient Brochure for your clients.

How can I be certain DentaPure is working? Do I need to test it?

DentaPure has been registered by the EPA and FDA to guarantee ≤ 200 CFU/mL for the life of the cartridge. Costly and time intensive testing is not necessary to ensure DentaPure is working.

Will DentaPure corrode or etch metal parts in my dental unit?

No. Studies show there is no corrosion or etching of metal parts in a dental unit unlike bleach or peroxide based cleaners.

Will DentaPure interfere with the setting of my dentin bonding agents?

No. Studies show there is no effect on the setting of dentin bonding agents due to the use of DentaPure. Learn more

What about water heaters and cup fillers on my dental unit?

DentaPure strongly recommends the removal of waterline heaters as they provide the perfect growth environment for bacteria. Cup fillers should be rerouted to a water source not being treated by DentaPure. This prevents depleting the iodine in the DentaPure cartridge prematurely. The cup filler will have a far lower bacteria count than dental handpieces and air/water syringes due to the larger diameter waterlines and flow quantities of water.

Is there any independent testing information available on DentaPure?

Yes. The ADA, The Dental Advisor, and the United States Air Force have tested DentaPure.

Will DentaPure in my wastewater cause problems with Federal, local, or state water regulations?

No. DentaPure does not leave harmful substances in your wastewater and will not expose your practice to regulatory limits and consequences that pertain to hazardous wastes.

Who installs DentaPure on the units?

The DP40B and DP365B are easily self-installed within a few minutes. We recommend the municipal systems, DP90M and DP365M, be installed by a service technician from your preferred dental dealer.

Do I still have to clean my bottle if I use DentaPure?

Yes, DentaPure only purifies the water that passes through the cartridge. It is important to empty and rinse the bottle nightly, and begin the morning with a fresh bottle. This minimizes the need to clean the bottles.

Do I need to buy a special bottle to use DentaPure?

No. DentaPure cartridges work with all existing bottles, including the two-liter quick disconnect style.

Where can I purchase DentaPure?

DentaPure is available through most dental supply dealers.
