We are being challenged every day to grow as professionals. It is often difficult to keep up with all of the new information that seems to bombard us. The necessity of oral cancer screening, routinely, on a younger demographic. Infection Prevention and Control guidelines that must be implemented. The impact on oral health that the legalization of cannabis will have. Pre-med requirements. Elder Abuse and how to respond when we see signs of it in our treatment room. MeToo in the workplace. Periodontal disease associated with a myriad of other afflictions. And so much more.
Maintaining professionalism when faced with ever-changing information is a daunting task. Each one of the topics mentioned above deserves investigation to ensure that we are provided true best-practice, based on current knowledge.
In this article we will focus on the disease that we deal with on a daily, often hourly, basis. There is exciting news on this front.
Fortunately, we have recently been presented with new classifications for periodontal disease which will clarify diagnosis and therefore, treatment protocols. This is cause for celebration!
The 1999 Periodontal Classifications, were structured as (broad categories only here):
For some, the many sub-categories within each of these headings, seemed to complicate an already difficult disease and it was not always beneficial in helping to determine a diagnosis and an appropriate treatment plan.
In 2016, the Canadian Journal of Dental Hygiene published an article titled, “Current status of the classification periodontal diseases” .¹ In this paper, the authors point out that a World Workshop in Clinical Periodontics was planning to meet in November 2017. The focus would be the limitations of the existing periodontal classifications, including clinical attachment levels (CAL) as main classification criterion, distinguishing between aggressive versus chronic, and localized versus general periodontitis. The task force involved in this meeting wanted to include additional parameters (beyond CAL) such as inflammation, bleeding on probing, increased probing depths and radiographic bone loss.
Often times as clinicians, using only CAL as the main classification criterion, left us unsettled. We know so much more about this disease than we did in 1999.
What we know about periodontal disease and the best methods of treatment continues to evolve. The classifications in 1989 were an advancement over what was available before that time. The 1999 groupings were a significant improvement over that. Now, we have ‘Stages’ and ‘Gradings’ to further our commitment to better diagnosis and treatment of this disease.
The World Workshop was held as planned in November 2017, with expert participants that included members of the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP). The purpose of the workshop was to review new technology, research and information with the goal of creating revised periodontal classifications. The results of that workshop are these new AAP guidelines that were announced in June 2018.
You may want to print some of these documents out and have them laminated to use as chairside resource tools. The information they contain will be a valuable asset to client education. They can be found in printable version at: perio.org/2017wwdc
This introductory paper provides an overview and is a good place to start with this new information.
The steps and staging and grading will make consistent diagnosis, easier. It will also help clients to understand when we are communicating that diagnosis. The new classifications present periodontitis in much the same way that other diseases are categorized, as stages. Most people are familiar with the concept that Stage IV cancer is more serious than Stage I. The same is true for periodontitis.
The “Three Steps to Staging and Grading a Patient” include:
Step 1: “Initial Case Overview to Assess the Disease” – then using the findings from this assessment you determine the ‘stage’ of disease.
Step 2: “Establish Stage” – divided into two sections “mild to moderate” and “moderate to severe”. Then, to address severity, complexity and extent and distribution of periodontitis, you assign a ‘grade’.
Step 3: “Establish Grade” – focus on client characteristics and risk factors, systemic influences and evaluation from previous treatment(s).
The four stages of periodontitis are based on the amount of damage that has already occurred. The factors measured include: interdental clinical attachment loss, radiographic bone loss, tooth loss and probing depths for Stage I and II. Additionally, furcation involvement, ridge defects and bite collapse are involved in Stages III and IV.
The ‘Grading’ portion of the new classification system allows us to incorporate other indicators of disease in order to determine how much risk a client has for further progression of periodontitis.
The “Primary criteria are bone loss or CAL, age, case phenotype and biofilm deposits. Grade modifiers include smoking and diabetes. For example, a client could have Stage III which indicates damage so there has been previous active disease. They are a Grade A though, now in ‘remission’ so the risk of progression is low. This client would obviously need different therapy than one who was Stage III, Grade C.
As we continue to learn about the causes of periodontal disease and the many associations with systemic health and wellness, the experts will undoubtedly be required to provide further revisions to these classifications in the future.
As healthcare professionals, it is our responsibility to stay current with the results of the research that is being done. However, if we only read about the developments and do not put that new knowledge into practice, the only ones to benefit are ourselves.
I would encourage you to become familiar with the documents from the AAP and feel confident in your knowledge of the four stages of periodontal disease. Be able to discuss the implications of the severity, complexity, extent and distribution of each stage, in client terms. Then you will be able to educate your client in a manner that is clear and understandable for them. That will, in turn, lead to acceptance of the therapy protocol that is truly required.
When a client has a clear understanding of their disease and the potential for further destruction, they are better equipped to make the best decision for their own health. That is where the grading system offers such significant help. The ability to connect risk factors to the rate of periodontitis progression, using the chart as a guide, allows us to ‘paint a picture’ that is specific to particular client characteristics.
True quality assurance means that we not only investigate new concepts, skills and technology but actually adapt our practice to include current, evidence-based knowledge so that we are always striving to provide best practice.

Periodontal Disease is a bacterial contamination that is incessant and influences both the gums and the bone that underpins the tooth. It initially starts with the nearness of bacteria in the plaque, which is that vapid film that structures on your teeth every once in a while, cause the gum to encounter some measure of aggravation.
Gum disease is one of the serious dental problems which create a lot of complications. Gingivitis and Periodontitis are gum disease which is found among lot of people. If these diseases are remained untreated for a longer duration then it leads to a lot of trouble in the later stage. Many of the people do not know the exact difference between gingivitis and periodontitis. https://sabkadentist.com/differences-on-gingivitis-and-periodontitis/
The outlook is good if the disease is recognized early and treated aggressively. Once bone loss occurs, the prognosis depends on the severity of the loss. Quitting smoking is very important for Periodontal therapy to be successful. Lifelong maintenance will be required once the disease is controlled.
Moderate periodontitis may require more than scaling and root planning. Typically, we will do scaling and root-planning your teeth. If this does not take care of the problem, we may decide that you need surgical treatment.
