Coronal Polishing – Experience the Freedom of Selection

Disclosure: We value transparency at Today’s RDH. This article is sponsored content from Dentsply Sirona Preventive as part of our sponsored partner program.

Coronal polishing is typically done to remove stain for esthetic reasons and to remove extrinsic roughness caused by the stain to retard new plaque biofilm from developing.  A smoother surface is less likely to retain plaque, calculus, and stain which in turn can lead to a healthier oral environment.1

The question can be raised then, is it merely a cosmetic procedure? Regardless of the answer, we as clinicians know that the polishing portion of the dental hygiene visit is what many patients feel is the “cleaning” and they expect this process as a part of the procedure.

Incorporating individual patient needs and expectations into our treatment choices is an integral part of practicing evidence-based dentistry. Choosing the right equipment, applying the proper technique, utilizing the appropriate products and ensuring patient comfort can lead to better clinical outcomes and higher patient satisfaction.

Evolution of Coronal Polishing

Today’s coronal polishing agents are used for a much wider range of treatment modalities, including biofilm disruption before ultrasonic scaling, application of desensitizing pastes, and preparing teeth for sealants to list a few.

There are a variety of products that provide therapeutic benefits such as treatment of hypersensitivity. The instrumentation performed during adult prophylaxis, periodontal maintenance, and periodontal debridement (SRP) procedures can be painful at pre-existing hypersensitive sites and may result in new areas of transient hypersensitivity.  To manage hypersensitivity stimulated during and following periodontal instrumentation, a strategy for continuous care can include the usage of products such as Nupro® extra care prophylaxis paste with NovaMin®.  Nupro extra care prophylaxis pastes with NovaMin are clinically proven to provide immediate sensitivity relief that lasts up to 28 days, providing increased patient comfort with just one application2. The paste is free of gluten, dye, and sodium lauryl sulfate.

NovaMin is a calcium sodium phosphosilicate glass containing sodium, calcium, phosphorous and silica. On contact, NovaMin reacts with saliva allowing sodium ions to exchange with hydrogen ions, thus raising the pH.  At this elevated pH, calcium and phosphate precipitate as calcium phosphate.  Calcium phosphate crystallizes to build a new hydroxyapatite-like layer over exposed dentin and occlude dentinal tubules.   NovaMin® works quickly and efficiently, releasing calcium and phosphate, so your patients get a stronger, more acid-resistant layer to protect their teeth and to help ensure their comfort.3,4

The prophy paste, available in polishing and stain removal grits, is applied immediately before initiating instrumentation.  A one-minute onset time provides immediate tubule occlusion.  A second application of the Nupro extra care prophy paste after instrumentation is completed is the final polish providing tubule occlusion following instrumentation.

Handpiece Options

Selecting a hygiene-specific handpiece with a comfortable, ergonomic design is important to the clinician and should provide features that enhance the polishing procedure. Handpiece specifications currently advocated by ergonomists include lightweight and adequate balance, which allows for a relaxed grip, as well as a non-slip surface for ease of control.5 It is also highly recommended that the handpiece has a larger diameter to increase the pinch width of the operator, which would reduce the possibility of cumulative trauma disorders. 5

Cordless Handpieces

More hygienists are providing services in settings outside of the traditional dental office, i.e., long-term care facilities, schools, mobile units, remote mission facilities, homebound patient residences, and locations without conventional air and water hookups. The innovation of cordless handpieces has been an asset in these environments.

Cordless handpieces are noticeably quieter than air-driven devices, which is attractive for the patient but also protective for the clinician. It is essential for the RDH to be efficient and effective in the polishing procedure but also be mindful of effective polishing parameters and the iatrogenic problems that can occur from using excessive speed and pressure.6

Pedal Free Cordless Handpieces

Nupro Freedom® Cordless Prophy System with SmartMode® Technology provides clinicians with an innovative method of controlling the speed and the power of the prophy cup. The handpiece is intuitive, allowing the clinician to fully control the handpiece function solely in their hand without pushing buttons or reaching for foot pedals.

The speed of the rubber cup intuitively increases with the amount of contact pressure applied against a tooth surface; the rpm speed will subsequently decrease as less pressure is applied.  The elimination of a foot pedal during the polishing procedure allows the clinician to move more fluidly and concentrate solely on the polishing process. The benefits are clear, and the technology is here.

Infection Prevention – Handpiece Sterilization

The Nupro Freedom® Cordless Prophy System with SmartMode® Technology provides a cost-effective solution to comply with the CDC Infection Prevention Guidelines. In 2008, the Centers for Disease Control (CDC), in its Guideline for Disinfection and Sterilization in Healthcare Facilities, reminded clinicians that “Handpieces can be contaminated internally with patient material and should be heat sterilized after each patient. Handpieces that cannot be heat sterilized should not be used.” No handpiece should be used on more than one patient without being autoclaved between patients. Barrier protection and wiping down with a disinfectant alone does not ensure prevention of cross-contamination.

The Nupro Freedom Cordless Prophy System with SmartMode Technology is designed with engineering controls which include autoclavable outer sheaths that have fluid seals, isolating the inner module from patient contact while providing a secure infection control barrier. Per CDC guidelines, the inner module of the system is considered a non-critical device and should be covered with an FDA-cleared disposable barrier and cleaned and disinfected with an EPA-registered hospital disinfectant labeled for tuberculocidal activity after each use.7

Complying with the CDC guidelines regarding dental handpieces is a significant aspect of infection prevention in the office, and this system allows you to do that at a fraction of the cost of buying separate handpieces.

Disposable Prophy Angles

Choosing the dental hygiene handpiece that feels right in your hand should be complemented by a well-designed disposable prophy angle. A high quality disposable prophy angle has splatter-reducing cup styles and webbing features that allow for greater interproximal contact. The Nupro Freedom® Slim angles feature a 14% more slender neck, a 16% shorter head along with a contra-angle design option.  These features combined provide the clinician improved visibility and maneuverability.

Conclusion

Today’s coronal polishing procedures and products address additional treatment considerations which can provide patients with relief from hypersensitivity during scaling procedures.  When assessing patients for individual treatment needs, creating opportunities to provide comfort along with therapeutic value is a win-win.

As clinicians, it is important to understand that we are only as good as what is in our hands. Choose a dental hygiene handpiece that offers a lightweight, balanced design and increased maneuverability. By reducing the wrist fatigue associated with cords and utilizing SmartMode Technology, you will experience the freedom of movement and portability as well.

Selective polishing has a new meaning. Choose what’s best for your patients’ safety, comfort, and optimal clinical outcomes.  Experience a whole new way to polish; your body and your patients will thank you.
