Dental Dipslides with Red Spot

Dental practices often require the use of dipslides to test the quality of the water used in dental unit water lines. The dipslides that we recommend for this purpose are our R2A agar dipslides.

These slides test for slower growing contaminants (stressed / chlorine tolerant bacteria). These types of bacteria can grow on the R2A agar despite the water being treated meaning that a more complete, realistic result is presented. The agar includes red spot dye which makes it easier to count colonies and interpret results.
Generally, practices should be looking for a result of less than 100 - 200 colony forming units / ml (it is important to follow the recommendations given by your local health authority).

R2A agar is a low nutrient agar and a longer and lower temperature incubation is recommended for these slides.

Incubation times are 5-7 days at 20°C or 28°C, or for 3 days at 35°C.

Flexible paddle

Flexible Paddle

Each dipslide features a virtually unbreakable and flexible paddle allowing for even, full surface testing.

Easy run off design

Easy Run Off Design

Due to the design of the dipslide, fluids will drain off quickly during testing.

Recessed Handle

Recessed Handle

Each slide has a handle built into the lid that is recessed to help keep your fingers dry during testing.

Side Indicator

Side Indicator

One side of the slide will have a circle indicator so you know which side was used for testing which type of contaminant.

Dual sided paddle

Dual Sided

Each dipslide is dual sided to allow multiple contamination testing with one test.

Thick reliable Agar

Thick Reliable Agar

Each agar is thick (approx 4mm) and raised above the dipslide to allow for easy surface testing.

These slides include red spot which makes it easier to view and count colonies.

How to use Dental dip slides

Remove Dental slide from tube

Step 1 : Remove slide

Carefully remove the sterile Dental dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).

Surface testing

Step 2 : If Surface Testing

For surface testing, press the Dental dipslide onto the surface. If needed, place a finger on the bottom of the slide (on the plastic, not the agar) to apply extra pressure.

Liquid Testing

Step 2 : If liquid testing

For liquid testing, immerse the Dental dipslide into the fluid for 10 seconds then remove and allow to drain for a few seconds.

Swab Testing

Step 2 : If swab testing

Apply a sample of the test substance to a sterile swab and gently apply to the agars.

Incubate the dipslide

Step 3 : Incubate Slide

Label the tube with the included stickers then place the slide into an incubator and allow to incubate.

compare dipslide results

Step 4 : Compare results

Count the amount of colonies that have grown on the slide and compare them to the comparison chart provided.

Customer Questions

Q

Is it water from the tap or the water from the dental chair that you used to test the dip slide

A

The chair waterline unit will need testing as biofilm can build up in the unit. In some cases, source water may be contaminated. If bacteria is present in the DUWL output water, it cannot be ruled out that the source water hasn't contributed to the contamination. So to be thorough, it is usually best to test both.

Q

If someone can send me an action plan if we see 99+ red dots? what solution do use etc? Thanks

A

Hello, This is not something we can advise on (you would need to speak to the appropriate regulator regarding this).

Q

Are the R2A - Low Nutrient Agar and the Orion MX8 Dipslide incubator compatible?

A

Whilst the slide would fit in a MX8, the MX8 does not have a variable temperature. As such, it would incubate the R2A at an incorrect temperature (needs to be 5-7 days at 20°C or 28°C, or for 3 days at 35°C). However, you can choose to purchase the 35°C version of the MX8 by selecting this option from the dropdown when purchasing. Alternatively, you could purchase the MX10 which has variable temperature control.

Q

How often should I carry out the tests?

A

Feedback from our customers suggests that most practices use dipslides to test their DUWLS (dental unit waterlines) quarterly or more frequently but we always suggest that you contact the appropriate local regulatory body for advise on how often to perform tests.

Using dipslides is a good way of monitoring water quality and can help you quickly assess if you have any microbiological contamination. You can then action an appropriate response.

In regards to DUWLS, dipslides should never replace testing by UKAS accredited labs. They are just an extra tool to help you regularly monitor your waterlines and keep aware of any contamination issues that may occur.

If dipslide testing is undertaken, the Department of Health recommends that 'the TVC should be expected to lie in the range of 100 to 200 colony forming units per millilitre (cfu/ml)'. This roughly equates to the 102 section of our chart which equates to 100 cfu/ml (approx 2 visible colonies on the dipslide).

Please note that our dipslides are not a legionella test. We recommend that you always follow industry guidelines.
