Waterline Shocking with A-dec

When I first thought of shocking the lines of our dental operatories, I definitely imagined a much more intricate process of getting the proper chemicals into our waterlines and becoming a chemist to perform this much needed maintenance procedure. However, thanks to A-dec, the products are so easy to understand and implement that it takes out so much of the stress of the process. To see the step in action, see our latest video all about shocking:



Here are a few things we’ve learned about shocking your units that have helped.

  1. Put it on your calendar to test and shock. Do you feel like time is flying? Days and weeks fly by and before we know it, a month is gone and we haven’t tested our ops. So, setting a reminder right on your practice management software is the best way to keep on top of it.

  2. Don’t be scared of the process. I think the 1st time I tested, I was very scared to find out the results. But it’s better now than never and get your op on a path of a low bacteria count. Ops fail all the time, which is why shocking is a thing. When you need to shock, know you’re in good company.

  3. Place a sign (like the one that comes with the A-dec shocking system) on your chair while the solution is in the lines. Without fail, someone will forget or won’t be told the chair is out of commission for a while. Having the sign keeps the lines of communication clear.

Have you shocked your lines before? What have you learned as you’ve been doing it?

Better Visibility with the Hoopla Retractor

The other day, I had a patient scheduled with me for nonsurgical periodontal therapy. It had been many years since seeing a dentist, and they knew something was going on with their gingival since it regularly bled as they brushed their teeth. Even though the patient knew they needed care, being at the dentist and with a dental hygienist can be a nerve wracking experience. This patient was no different. They were nervous to be with me, nervous about getting an injection to be numb, and their anxious energy was filling the room. I don’t know about you, but I always feel a bit of heightened stress when the patient is very nervous. After explaining the injection, what it would feel like, and the possibility of feeling a “zing” feeling with the IA, I sat the patient back and started to retract the cheek. Even with the coaching, the prepping, and calming of the patient, their tongue had a mind of its own. This definitely added to the stress in the room, having a needle in the patient's mouth while trying to wrangle a tongue and explain to the patient to relax. 

After several minutes of trying (and not getting very far), I needed reinforcements to help hold the tongue. Unfortunately, the dental assistants were busy right then, and I was on my own to complete the injection. So, I decided to try a retractor to hold the cheeks so I had a free hand to gently hold the tongue. And it totally worked! It was like having an extra hand there to see the injection site better, hold the patient, and have a smoother experience with this patient. I was definitely  kicking myself after this experience that I didn’t grab the retractor sooner and save so much time and energy for both the patient and myself.

If you find that you’re in a procedure and need an extra hand, try retraction like the Hoopla from Zyris! They are easy to place and can be used for so many things we do during the day- from sealants, to air powder polishing, to injections. To learn more about the Hoopla, check out our latest video:

A huge thank you to Zyris for sharing our same goals of empowering clinicians to be their best with great products, and for supporting us at Hygiene Edge.

Maintaining Your Dental Waterlines with A-dec

What can we do during the month to keep our waterlines in top shape and keep the bacteria counts below the required CDC amount? Lucky for us in our busy dental day, maintenance is very easy and can be applied to our ops with 1 easy step- a tablet!

Tabs contain a low- level antibacterial to help keep your waterlines clean. A few helpful tips with the tabs:

  1. Always add your tablet to a full water bottle of fresh water. This will keep the balance between water and antibacterial at an optimal  level. If your bottle is half full in the morning and you want to top it off to last you the day, empty out the existing water, refill, and add a tablet.

  2. Give the tablet 2 minutes to dissolve before using the water. Giving time will allow the antibacterial to move throughout the entire bottle, and keep a great balance in your waterlines. When you’re replacing your water, do it 1st thing in the morning to give it time to dissolve before your patient is in your chair.

  3. Drop the tablet into your bottle without touching the tablet. To prevent cross contamination from your hand to your bottle and keep the bacteria counts down,  gently open the packaging and drop the tablet in while your hand is only handling the paper.

To see how to maintain in action, see our latest video:

We are so excited for you on this waterline journey with us, with a huge step being maintenance! A big thank you to A-dec for supporting us at Hygiene Edge and allowing us to shine a light on such an important and often forgotten about topic. 

Don’t forget to check out the entire Series!

Graceys VS Universal Instruments

Here is a plea to have gracey instruments in your office. Hear me out- I know they’re an extra expense, you need to have 2 instruments per tooth, and they add extra mess to your tray. However, if you’re working on pockets greater than 4mm, these specialized instruments are key to reaching the base of the pocket. There is a huge difference between these two instruments, what they are used for, and how they each are utilized to treat very different patients. Let’s break them down.

Universal Instruments:

  1. Design:

    • Blade Angle: Universal instruments have two cutting edges per working end. The blade is set at a 90-degree angle to the terminal shank.

    • Shape: The back is rounded, and the working end is semicircular in cross-section.

    • Cutting Edges: Both edges are used, allowing it to be applied to all tooth surfaces.

  2. Application:

    • Designed for all areas of the mouth (hence, “universal”).

    • Commonly used for heavy deposits due to their robust design.

    • Examples: Columbia 13/14, Barnhart 5/6.

  3. Technique:

    • Requires tilting the shank to achieve the correct blade-to-tooth angulation (70–80 degrees).

    • Effective but may require more precision to adapt correctly to curved surfaces.


Gracey Curettes:

  1. Design:

    • Blade Angle: Gracey curettes have a 70-degree blade angle to the terminal shank, making only one cutting edge functional (lower edge).

    • Shape: Also has a semicircular cross-section, but the shank and blade are more angulated and area-specific.

  2. Application:

    • Designed for specific areas of the mouth:

      • Example: Gracey 1/2 for anterior teeth, 11/12 or 15/16 for mesial surfaces, 13/14 or 17/18 for distal surfaces.

    • Ideal for fine scaling and root planing, especially subgingivally.

    • Provides better adaptability to root morphology and furcations.

  3. Technique:

    • Easier to achieve proper angulation due to the pre-set blade angle.

    • Less effective for removing heavy deposits compared to universal curettes.

Testing Your Waterlines with A-dec

Has there ever been a time when you’ve been sitting in a dental hygiene CE Course and have felt completely overwhelmed? Like the information is definitely important, but felt cumbersome to apply it to your clinical life? Waterline testing and shocking was that topic for me. I remember sitting in the webinar class 9 months pregnant trying to get some classes in before having a baby and life was  quickly changing for me. I wasn’t super interested in the topic, but the speaker was amazing. I was blown away by the stats and facts about waterlines, bacteria, the importance of cleaning out our waterlines in the dental office, and how it was our responsibility to keep our waterlines below the CDC recommended 500 CFU/mL of water of heterotrophic water bacteria. I was also feeling very overwhelmed because we had not been shocking and testing at the office I was working at. I was feeling really awful, some shame,  and didn’t know where to start. 

However, once you actually see how it’s done and the steps broken down, it definitely doesn’t feel as overwhelming.  We have loved going through each step with A-dec and seeing how we can easily perform testing, shocking and maintaining throughout our hygiene days when we already are stretched thin for time.

Honesty, the most important thing to remember when it comes to waterline testing is now is the time to start, and not stress about the past. I remember being so nervous to test my waterlines just in case something popped up that wasn’t desirable. However, knowing better means doing better from here on out. 

If you’re feeling the same way about testing and shocking, we are so excited for this three part video series thanks to A-dec. During these series, we’re breaking down the steps to testing, maintaining and shocking to make it easy to use in your practice starting today. Plus, if you’re looking for an easy way to test out a shocking solution, A-dec has made it easy to order your very own samples. We actually used this sample ordering website to get the product to make these videos, which was very easy and shipped to us quickly. 

This week, we’re introducing the 1st video of this series: Testing. Testing is crucial to know how to maintain your waterlines and very simple. Check it out below:

A glimpse into the next 100 years of dental hygiene according to AI

The next 100 years of dental hygiene, according to AI.

I asked chat GPT the following questions, and the answers are inspiring. A springboard for our profession to launch oral health into the future. I encourage you to review the following and choose your favorite and chase it to improve our profession and the oral health of the world. Let me know in the comments what you see for our future.

What do you think the dental hygiene profession will look like in 100 years with current health care trends.

Personalized, AI-Driven Treatment Plans: AI algorithms could develop highly personalized oral care plans based on genetic and lifestyle factors, providing recommendations and adjustments in real-time for each patient.

Nanotechnology for Preventive and Therapeutic Care: Nanotechnology may allow for microscopic devices to be embedded in the mouth, constantly monitoring oral health, delivering treatments directly to problem areas, and even rebuilding tooth enamel at a molecular level.

Genetic-Based Preventive Care: Genetic testing may become a routine part of oral health care, helping identify individuals at higher risk for conditions like periodontitis, allowing for earlier interventions or tailored preventive strategies.

Virtual and Augmented Reality Training and Treatment: Virtual and augmented reality could be used to train hygienists, provide remote consultations, and enable patients to visualize their treatment plans and oral health progression in real-time.

Widespread Use of Robotics in Clinical Settings: Robots may assist in procedures, improving precision, and perhaps even performing routine hygiene tasks, allowing hygienists to focus more on patient interaction and customized care.

Oral Health Integration in Holistic Health Programs: Oral health will be more closely integrated into overall health care, with hygienists working as part of interdisciplinary teams addressing systemic conditions linked to oral health, like diabetes and cardiovascular diseases.



What do you think dental insurance will look like in 100 years with current health care trends.

Comprehensive Health-Dental Insurance Integration: Dental insurance might be fully integrated with general health insurance, recognizing the link between oral health and systemic health. This could ensure that dental care is covered as an essential part of overall health maintenance, with fewer separate policies or exclusions.

Focus on Preventive Coverage and Incentives: Insurance plans might heavily emphasize preventive care, rewarding patients who adhere to preventive practices like regular check-ups, cleanings, and oral health monitoring. Coverage could extend to innovative preventive treatments, reducing the need for costly interventions later on.

AI-Driven, Personalized Premiums and Coverage: Using AI and data analysis, insurers might set premiums and coverage based on a patient’s unique risk factors, including genetics, lifestyle, and health history. Policies could adapt in real time, updating coverage and costs as a person’s oral health profile changes over time.

Global, Universal Access and Reduced Out-of-Pocket Costs: With health care trends shifting toward equity and accessibility, universal dental insurance could become common, making oral health care affordable and accessible worldwide. Out-of-pocket costs may decrease significantly as public health initiatives prioritize preventive and accessible care


What do you think work place ergonomics and safety will look like in 100 years with current health care trends.

Dynamic, AI-Enhanced Ergonomic Monitoring: AI systems may continuously monitor workers’ postures and movements, providing instant feedback and making real-time adjustments to workstations. This could help prevent injuries by encouraging healthier habits and reducing repetitive strain through subtle reminders or automatic adjustments.

Wearable Health Sensors: Health care workers might wear discreet, multi-functional health sensors that track stress, posture, and muscle strain. These devices could alert workers and managers when rest or adjustments are needed, fostering a proactive approach to both physical and mental health.

Exoskeletons and Robotic Support Systems: Exoskeletons or robotic assistive devices could help workers handle physically demanding tasks, reducing strain on muscles and joints. These could be standard in hospitals, aiding in lifting, bending, or assisting patients, thus lowering the risk of musculoskeletal injuries.

Ergonomics-Centric Workspace Designs: Workspaces will likely be designed with flexibility, automation, and ergonomics as primary factors, incorporating customizable lighting, noise control, and air quality adjustments to support worker health. Restorative spaces for breaks, complete with guided relaxation and stretching programs, may be embedded into the workplace, promoting overall wellness.

Use of A Sickle During Periodontal Therapy

This week, Jessica Atkinson demonstrates her technique for using a sickle scaler to effectively reach beneath the contact area during periodontal therapy. With its narrow, triangular-shaped tip, the sickle scaler is an ideal tool for navigating tight interproximal spaces. While it's traditionally not recommended for use on the cementum covered root surfaces due to the potential for damage, having a sickle scaler on hand during periodontal therapy is invaluable for scaling on enamel surfaces, especially when removing those last bits of tenacious deposits.
