Treating Gingivitis

A mechanism for treating those with moderate to severe gingivitis and no attachment loss

CDT 4346: scaling in the presence of generalized moderate or severe gingival inflammation - full mouth, after oral evaluation

The removal of plaque, calculus and stains from supra- and sub-gingival tooth surfaces when there is generalized moderate or severe gingival inflammation in the absence of periodontitis. It is indicated for patients who have swollen, inflamed gingiva, generalized suprabony pockets, and moderate to severe bleeding on probing. Should not be reported in conjunction with prophylaxis, scaling and root planing, or debridement procedures.

How do I use this code?

The ADA Guide to Reporting D4346 is an excellent resource on how to implement the new code. The document references the American Academy of Periodontology (AAP) definition of chronic gingivitis to be when 30% or more of the patient's teeth or sites are involved.

Both the ADA and the ADHA offer webinars on how to effectively use the new code.

Preventing Gingivitis

The new D4346 code is a much needed tool to help effectively treat moderate to severe gingivitis. But patients need the right self-care tools to use at home to help keep gingivitis from re-occurring. The Waterpik® Water Flosser is both easy to use and has been shown to be significantly more effective than string floss at reducing bleeding and gingival inflammation.

Preventing Musculoskeletal Disorders With Loupes
By JoNell Bly, RDH, BS
Scource: http://hs.orascoptic.com/rdhelite

Significant evidence suggests that dental hygienists face a high probability of developing a musculoskeletal disorder (MSD) related to their work. A literature review indicated that the prevalence of MSDs in dental hygienists is as high as 93%, with pain occurring most frequently in the neck, shoulders, hands, and wrists.1 Much ergonomic research has focused on preventive strategies—such as loupes—that may help reduce the effects of the physical demands of patient care.

Maintaining a neutral posture for the majority of the workday is key to reducing work-related pain.2 Studies have shown that dental hygiene students wearing magnification loupes experienced improved posture and positioning while performing clinical duties.3–5 Another study found that clinicians working with neck flexion over 20° for 70% of their workday were at an increased risk of neck pain.6 Wearing loupes with the correct declination angle places the clinician’s head at an appropriate tilt for ergonomic health, reducing the risk of work-related pain. Other authors have reported a correlation between dental hygienists’ use of magnification systems and a reduced incidence of MSD pain.7,8 Today, loupes are available in small, light frames with high-quality magnification lenses and a variety of declination angles. These improvements provide clinicians with additional significant ergonomic benefits.

♦  Orascoptic works to empower dental hygienists and therapists with the proper tools to promote a long and healthy career. Focusing on advanced product performance and clinician-first features, we have developed a complete line of dental hygiene loupes, surgical headlights, safety eyewear, and ergonomic seating.

Often clinicians do not seek professional help for MSDs until the pain becomes so severe that it impedes their ability to work. A case study account dealing with practicing dental hygienists experiencing MSD symptoms indicated the clinicians reported lower levels of pain when they incorporated a variety of ergonomic strategies into their workday.9 These case studies highlight the multifactorial solutions that are necessary when confronting the issue of musculoskeletal pain. This was further emphasized in a study that demonstrated dental students using a combination of loupes and ergonomic saddle chairs had significantly better posture than students in traditional dental seating without magnification.10

In order to achieve the optimal results from magnification, clinicians must research various types of loupes and have proper measurements taken for a custom fit. Improperly fitting loupes may actually exacerbate work injuries.7,11 When purchasing loupes, clinicians should consider their height and build, facial features, vision requirements, and working posture. Seeking professional consultation with a highly regarded loupes manufacturer will help to ensure selection of the correct magnification lens.

In conclusion, the use of loupes can improve the ergonomics of dental hygiene practice and help clinicians avoid debilitating injuries. Purchasing loupes from a trusted source who offers a generous trial period and product support is essential to the successful incorporation of loupes into the practice of dental hygiene.
