The overall classification system aimed to differentiate the more common forms of periodontitis, i.e. Journal of Clinical Periodontology, 2019. Comparison of sTREM‐1 and associated periodontal and bacterial factors before/after periodontal therapy, and impact of psychosocial factors. Report of a case. Lack of ability to resolve the issue is illustrated in the changes to the classification system that progressively emphasized either differences or commonalities. Grade of periodontitis is estimated with direct or indirect evidence of progression rate in three categories: slow, moderate and rapid progression (Grade A-C). Antimicrobial efficacy of indocyanine green-mediated photodynamic therapy compared with Salvadora persica gel application in the treatment of moderate and deep pockets in periodontitis. EFP publications include the sector-leading Journal of Clinical Periodontology, the research summary JCP Digest, and Perio Insight, which offers expert views on periodontal science and clinical practice. Differential diagnosis is based on history and the specific signs and symptoms of necrotizing periodontitis and the presence or absence of an uncommon systemic disease that definitively alters the host immune response. International Journal of Chronic Obstructive Pulmonary Disease. Staging is utilized to classify the severity and extent of an individual based on currently measurable extent of destroyed and damaged tissue attributable to periodontitis. Do the clinical criteria used to diagnose periodontitis affect the association with prematurity?. Validity of a self‐reported questionnaire for periodontitis in a Spanish population. EFP Staging Parameters (by Prof. Tonetti) Periodontitis stage TONETTI ET AL. If the patient has severe systemic disease, as indicated by their American Society of Anesthesiologists (ASA) status, this can seriously affect the clinician's ability to control disease progression due to the patient's inability to withstand proper treatment or their inability to attend necessary maintenance care. Working off-campus? Other factors that need to be considered in formulating a diagnostic classification include the medical status of the patient and the level of expertise needed to provide appropriate care. Host-Modulation Therapy and Chair-Side Diagnostics in the Treatment of Peri-Implantitis. Clinical and Microbiological Outcomes of Topical Aloe Vera Gel PERIODONTITIS: GRADING Grading aims to indicate the rate of periodontitis progression, responsiveness to standard therapy, and potential impact on systemic health. A notable exception is successful periodontal regeneration that may, through improvement of tooth support, effectively improve CAL and RBL of the specific tooth. Periodontal health for a better life. Emerging risk factors like obesity, specific genetic factors, physical activity, or nutrition may one day contribute to assessment, and a flexible approach needs to be devised to ensure that the case‐definition system will adapt to the emerging evidence. Furthermore, case definitions may be applied in different contexts: patient care, epidemiological surveys and research on disease mechanisms or therapeutic outcomes, as discussed in Appendix A in the online Journal of Clinical Periodontology. Accuracy of Panoramic Radiograph for Diagnosing Periodontitis Comparing to Clinical Examination. Treatment of periodontitis improves the atherosclerotic profile: a systematic review and meta-analysis. Risk factor analysis is used as grade modifier.ConclusionsThe paper describes a simple matrix based on stage and grade to appropriately define periodontitis in an individual patient. it is important to identify approaches to capture some dimensions of the potential systemic impact of a specific periodontitis case and its treatment to provide the basis for focusing attention on this issue and beginning to collect evidence necessary to assess whether effective treatment of certain cases of periodontitis truly influence systemic disease in a meaningful way. For example, a stage and grade case definition could be characterized by moderate attachment loss (stage II), the assumption of moderate rate of progression (grade B) modified by the presence of poorly controlled Type II diabetes (a risk factor that is able to shift the grade definition to rapid progression or grade C). It also provides the necessary framework for introduction of biomarkers in diagnosis and prognosis. The aim of this manuscript is to review evidence and rationale for a revision of the current classification, to provide a framework for case definition that fully implicates state-of-the-art knowledge and can be adapted as new evidence emerges, and to suggest a case definition system that…. It is suggested that a case definition based on a matrix of periodontitis stage and periodontitis grade be adopted. Evidence gathered in four commissioned reviews was analyzed and interpreted with special emphasis to changes with regards to the understanding available prior to the 1999 classification. An Approach to Assess Early Detection of Periodontal Disease in Young and Adult Individuals in Colombia for Prevention. III. Comparison of two different periodontal risk assessment methods with regard to their agreement: Periodontal risk assessment versus periodontal risk calculator. Long-term periodontitis treatment costs according to the 2018 classification of periodontal diseases. With regard to periodontitis as a direct manifestation of systemic disease, the recommendation is to follow the classification of the primary disease according to the respective International Statistical Classification of Diseases and Related Health Problems (ICD) codes. Grade of periodontitis is estimated with direct or indirect evidence of progression rate in three categories: slow, moderate and rapid progression (Grade A-C). The 2018 periodontitis case definition improves accuracy performance of full-mouth partial diagnostic protocols. 2018). Periodontitis as a manifestation of systemic diseases. Periodontitis as a direct manifestation of systemic diseases. Risk factor analysis is used as grade modifier. Implementation of Patient-Based Risk Assessment in Practice. Application of weighted gene co-expression network analysis to reveal key modules and hub genes in generalized aggressive periodontitis. The severity score is primarily based on interdental CAL in recognition of low specificity of both pocketing and marginal bone loss, although marginal bone loss is also included as an additional descriptor. Evidence linking the role of periodontal viruses in coronary artery disease with and without periodontitis. However, if other factors are present in the complexity dimension that influence the disease then modification of the initial stage assignment may be required. This stage is characterized by the presence of deep periodontal lesions that extend to the apical portion of the root and/or history of multiple tooth loss; it is frequently complicated by tooth hypermobility due to secondary occlusal trauma and the sequelae of tooth loss: posterior bite collapse and drifting. Since the 1999 workshop considerable evidence has emerged concerning potential effects of periodontitis on systemic diseases. Staging and grading of periodontitis: Framework and proposal of a new classification and case definition By Maurizio S. Tonetti, Henry Greenwell and Kenneth S. Kornman Cite These can be assessed in each individual case at diagnosis by appropriate anamnestic, clinical, and imaging data. Staging and grading of periodontitis: Framework and proposal of a new classification and case definition Maurizio S. Tonetti1 | Henry Greenwell2 ... Prof. Maurizio Tonetti, Periodontology, Faculty of Dentistry, University of Hong Kong, Prince Philip Dental Hospital 34, Relations of Psychosocial Factors and Cortisol with Periodontal and Bacterial Parameters: A Prospective Clinical Study in 30 Patients with Periodontitis Before and After Non-Surgical Treatment. Clinicians should approach grading by assuming a moderate rate of progression (grade B) and look for direct and indirect measures of actual progression in the past as a means of improving the establishment of prognosis for the individual patient. Periodontitis Stage I Stage II Stage III Stage IV Staging and Grading Periodontitis The 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions resulted in a new classification of periodontitis characterized by a multidimensional staging and grading system. Periodontal regeneration versus extraction and dental implant or prosthetic replacement of teeth severely compromised by attachment loss to the apex: A randomized controlled clinical trial reporting 10‐year outcomes, survival analysis and mean cumulative cost of recurrence. Usefulness of hemoglobin examination in gingival crevicular fluid during supportive periodontal therapy to diagnose the pre-symptomatic state in periodontal disease. The reviews commissioned for this workshop 13–16 have indicated that there is no evidence to suggest that such forms of periodontitis have a unique pathophysiology, rather the complex interplay of risk factors in a multifactorial disease model may explain the phenotypes of periodontitis in exposed patients. Incidence and progression of gingival recession over 4 years: A population‐based longitudinal study. Greenwell H(1), Wang HL(2), Kornman KS(2), Tonetti MS(3). Periodontitis and circulating blood cell profiles: a systematic review and meta-analysis. and the observed CAL cannot be ascribed to non‐periodontal causes such as: 1) gingival recession of traumatic origin; 2) dental caries extending in the cervical area of the tooth; 3) the presence of CAL on the distal aspect of a second molar and associated with malposition or extraction of a third molar, 4) an endodontic lesion draining through the marginal periodontium; and 5) the occurrence of a vertical root fracture. Periodontitis is then further characterized by a staging and grading system. This is detected as clinical attachment loss (CAL) by circumferential assessment of the erupted dentition with a standardized periodontal probe with reference to the cemento‐enamel junction (CEJ). 6 Staging is established by factors such as clinical attachment loss, bone loss, probing depth, furcation involvement, mobility, and tooth loss. Retrospectively analysed tooth loss in periodontally compromised patients: Long‐term results 10 years after active periodontal therapy—Patient‐related outcomes. International Journal of Environmental Research and Public Health. Burt and Eklund's Dentistry, Dental Practice, and the Community. Stage II represents established periodontitis in which a carefully performed clinical periodontal examination identifies the characteristic damages that periodontitis has caused to tooth support. The new classifications present periodontitis in much the same way that other diseases are categorized, as stages. Furthermore, the validity of many of the criteria for aggressive periodontitis has not been confirmed in adequately designed studies. Since the 1999 International Classification Workshop, it has become apparent that additional information beyond the specific form of periodontitis and the severity and extent of periodontal breakdown is necessary to more specifically characterize the impact of past disease on an individual patient's dentition and on treatment approaches needed to manage the case. For those individuals, biomarkers, some of which are currently available, may be valuable to augment information provided by standard clinical parameters. Stage I periodontitis is the borderland between gingivitis and periodontitis and represents the early stages of attachment loss. Grade of periodontitis is estimated with direct or indirect evidence of progression rate in three categories: slow, moderate and rapid progression (Grade A‐C). Identification of a patient as a periodontitis case, Identification of the specific form of periodontitis, and. The impact of smoking on non‐surgical periodontal therapy: A systematic review and meta‐analysis. There is little consistent evidence that aggressive and chronic periodontitis are different diseases, but there is evidence of multiple factors, and interactions among them, that influence clinically observable disease outcomes (phenotypes) at the individual level. 2 mm) to address measurement error with CAL detection with a periodontal probe would result in misclassification of initial periodontitis cases as gingivitis. The AAP released two documents titled “Three Steps to Staging and Grading a Patient” and “Staging and Grading Periodontitis.” A quick synopsis of the three stages are as follows; Step 1: Initial Case Overview to Assess Disease, the recommendation is to conduct a screening consisting of radiographs, probing depths, and missing teeth. Biomarkers may contribute to improved diagnostic accuracy in the early detection of periodontitis and are likely to provide decisive contributions to a better assessment of the grade of periodontitis. Mechanical Periodontal Therapy Recovered the Phagocytic Function of Monocytes in Periodontitis. To supplement staging, which provides a summary of clinical presentation, grade has been used as an assessment of the potential for a specific tumor to progress, i.e. specialist or general practitioner) and local conditions that may facilitate or impair detection of the CEJ, most notably the position of the gingival margin with respect to the CEJ, the presence of calculus or restorative margins. Besides the local complexity, it is recognized that individual case management may be complicated by medical factors or comorbidities. Staging and grading of periodontitis: Framework and proposal of a new classification and case definition, pages S149-S161. While devising a general framework, it seems relevant from a patient management standpoint to differentiate four stages of periodontitis. As it is recognized that individuals presenting with different severity/extent and resulting complexity of management may present different rates of progression of the disease and/or risk factors, the information derived from the staging of periodontitis should be supplemented by information on the inherent biological grade of the disease. Figure 2. The correspondence of 3D supporting bone loss and crown‐to‐root ratio to periodontitis classification. The charts below provide an overview. The added value of periodontal measurements for identification of diabetes among Saudi adults. The current proposal does not intend to minimize the importance or extent of evidence supporting direct distal effects of periodontal bacteremia on adverse pregnancy outcomes and potentially other systemic conditions; but focuses on the role of periodontitis as the second most frequent factor (obesity being the most frequent) that is well‐documented as a modifiable contributor to systemic inflammatory burden. Diabetes mellitus—Dental implants and periodontal disease. The 1999 case definition system is also based on severity. Biologically guided implant therapy: A diagnostic and therapeutic strategy of conservation and preservation based on periodontal staging and grading. Use the link below to share a full-text version of this article with your friends and colleagues. The New Periodontal classification system has a staging and grading system - instead of the previously used Case Types or descriptive severity. Such challenges again require a framework that will adapt to change as more precise ways to estimate individual susceptibility become available. Modestly sized periodontitis treatment studies of uncontrolled Type II diabetes have shown value in reducing hyperglycemia, although reductions in hyperglycemia have not been supported in some larger studies where the periodontal treatment outcomes were less clear.18, 60, 61 Although intriguing health economics analyses have shown a reduction in cost of care for multiple medical conditions following treatment for periodontitis,62 little direct periodontitis intervention evidence, beyond the diabetes experience, has convincingly demonstrated the potential value of effectively treating periodontitis relative to overall health benefits. The charts below provide an overview. Author information: (1)Graduate Periodontics, School of Dentistry, University of Louisville, Louisville, KY, USA. BACKGROUND The role of inflammation and genetics in periodontal disease. Careful evaluation of the stage II patient's response to standard treatment principles is essential, and the case grade plus treatment response may guide more intensive management for specific patients. And the powerful outcome of that multidimensional view is the ability to communicate better with patients, other professionals, and third parties. The majority of clinical cases of periodontitis present with a range of phenotypes that require different approaches to clinical management and offer different complexities that define the knowledge and experience necessary to successfully manage various cases. International Journal of Molecular Sciences. The objective of grading is to use whatever information is available to determine the likelihood of the case progressing at a greater rate than is typical for the majority of the population or responding less predictably to standard therapy. If the patient has risk factors that have been associated with more disease progression or less responsiveness to bacterial reduction therapies, the risk factor information can be used to modify the estimate of the patient's future course of disease. The AAP/Centers for Disease Control (CDC) case definition for epidemiologic surveillance and the EFP case definition for the purpose of risk factors research have been widely utilized.33, 34 Although the AAP/CDC and the sensitive EFP definition share similarities there are some important differences.

Staging of tumors is based on current observable clinical presentation including size or extent and whether it has metastasized. 8 For a full description of the phenotypes of each stage and grade of periodontitis, please refer to primary research article written by Tonetti and colleagues. Psychosocial aspects of periodontal disease diagnosis and treatment: A qualitative study. In most of successfully treated patients, complexity factors that might have contributed to baseline staging will have been resolved through treatment. Finally, one of the strong benefits of the staging and grading of periodontitis is that it is designed to accommodate regular review by an ad hoc international task force to ensure that the framework incorporates relevant new knowledge within an already functioning clinical application. The full text of this article hosted at is unavailable due to technical difficulties. Orthodontical Management of Secondary Dental Migration Associated with a Reduced Periodontium: A Case Report. In each stage of severity, it may be useful to identify subjects with different rates of disease progression and it is foreseen that, in the future, stage definition will be enriched by diagnostic tests enabling definition of the biological “grade” and/or susceptibility of periodontitis progression in the individual patient. crevicular fluid (GCF) biological molecular markers (MMP-8). We should anticipate that until more robust methods are validated, potentially salivary biomarkers or novel soft‐tissue imaging technologies, the level of training and experience with periodontal probing will greatly influence the identification of a case of initial periodontitis. vs. Photochemotherapy as an Adjunct to Non-surgical Periodontal The aim of this manuscript is to review evidence and rationale for a revision of the current classification, to provide a framework for case definition that fully implicates state‐of‐the‐art knowledge and can be adapted as new evidence emerges, and to suggest a case definition system that can be implemented in clinical practice, research and epidemiologic surveillance. Classification of Periodontal Diseases 2017 Since guidelines changed in 2017, the major change was the classification framework for periodontitis. Early diagnosis and definition of a population of susceptible individuals offers opportunities for early intervention and monitoring that may prove more cost‐effective at the population level as shallow lesions may provide specific options for both conventional mechanical biofilm removal and pharmacological agents delivered in oral hygiene aids. Levels of Matrix Metalloproteinase-8 After Intrapocket Treatment in Moderate Periodontitis Patients. This may be an example of how one might communicate current severity and extent of a disease, as well as the clinical complexities of managing the case. chronic and aggressive periodontitis, from the unusual necrotizing form of the disease (characterized by a unique pathophysiology, distinct clinical presentation and treatment), and the rare major genetic defects or acquired deficiencies in components of host defense (characterized by a primary systemic disorder that also expresses itself by premature tooth exfoliation). Reference Tonetti, M. S., Greenwell, H. & Kornman, K. S. (2018) Staging and grading of periodontitis: Framework and proposal of a new classification and case definition. The diagnostic classification presented in Table 3 provides definitions for four stages of periodontitis. Table 4 illustrates periodontitis grading based on primary criteria represented by the availability of direct or indirect evidence of periodontitis progression. Over the past 2 decades clinicians, educators, researchers and epidemiologists have voiced concern about their ability to correctly differentiate between aggressive and chronic periodontitis cases, and these difficulties have been a major rationale for a new classification workshop.11, To update evidence that has accumulated since the latest classification workshop, the organizing committee commissioned a review on acute periodontal lesions including necrotizing periodontitis,12 a review of manifestations of systemic diseases that affect the periodontal attachment apparatus,13 and three position papers that are relevant to the discussion of aggressive and chronic periodontitis.14-16. Only attachment loss attributable to periodontitis is used for the score.

Self‐reported bleeding on brushing as a predictor of bleeding on probing: Early observations from the deployment of an internet of things network of intelligent power‐driven toothbrushes in a supportive periodontal care population. Staging, an approach used for many years in oncology, has been recently discussed relative to periodontal disease66 and affords an opportunity to move beyond the one‐dimensional approach of using past destruction alone and furnishes a platform on which a multidimensional diagnostic classification can be built. Efficacy of antimicrobial photodynamic therapy with chloro-aluminum phthalocyanine on periodontal clinical parameters and salivary GSH and MDA levels in patients with periodontitis. Improved knowledge of how risk factors affect periodontitis (higher severity and extent at an earlier age) and treatment response (smaller degrees of improvements in surrogate outcomes and higher rates of tooth loss during supportive periodontal therapy40, 41, 44) indicate that risk factors should be considered in the classification of periodontitis. Recognized risk factors have not been previously included formally in the classification system of periodontitis but have been used as a descriptor to qualify the specific patient as a smoker or a patient with diabetes mellitus. Number of times cited according to CrossRef: Measurement and Distribution of Periodontal Diseases. Systemic conditions and oral health‐related quality of life of pregnant women of normal weight and who are overweight. Flowcharts for Easy Periodontal Diagnosis Based on the 2018 New Periodontal Classification. This explicitly acknowledges the evidence that most individuals and patients respond predictably to conventional approaches to prevent periodontitis and conventional therapeutic approaches and maintenance, while others may require more intensive and more frequent preventive care or therapeutic interventions, monitoring, and maintenance.19, 20, 63-65. A nomogram prediction for mandibular molar survival in Chinese patients with periodontitis: A 10‐year retrospective cohort study. Stage I to IV of periodontitis is defined based on severity (primarily periodontal breakdown with reference to root length and periodontitis‐associated tooth loss), complexity of management (pocket depth, infrabony defects, furcation involvement, tooth hypermobility, masticatory dysfunction) and additionally described as extent (localized or generalized). Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors. Marginal alveolar bone loss – a key secondary feature of periodontitis – is coupled with loss of attachment by inflammatory mediators. Treatment in Periodontitis. Likewise, if posterior bite collapse is present then the stage IV would be the appropriate stage diagnosis since the complexity is on the stage IV level. Prevalence and severity of periodontal disease in a historical Austrian population. Biomarkers in Periodontal Health and Disease. The complexity score is based on the local treatment complexity assuming the wish/need to eliminate local factors and takes into account factors like presence of vertical defects, furcation involvement, tooth hypermobility, drifting and/or flaring of teeth, tooth loss, ridge deficiency and loss of masticatory function. Aim: The objective of this study was to evaluate consistency and accuracy of the periodontitis staging and grading classification system. The staging and grading system in defining periodontitis cases: consistency and accuracy amongst periodontal experts, general dentists and undergraduate students. Association between periodontitis and anti-citrullinated protein antibodies in rheumatoid arthritis patients: a cross-sectional study. At present there is only emerging evidence to identify specific periodontitis cases in which periodontal treatment produces general health benefits. Biomarkers in Periodontal Disease and Systemic Health Intersection. See this chart from the AAP on staging and grading of periodontal disease. J Periodontol 2018;89 (Suppl 1): S159-S172. The number and the distribution of teeth with detectable periodontal breakdown has been part of current classification systems. Recognized risk factors, such as cigarette smoking or metabolic control of diabetes, affect the rate of progression of periodontitis and, consequently, may increase the conversion from one stage to the next. Another important limitation of current definitions of severe periodontitis is a paradox: whenever the worst affected teeth in the dentition are lost, severity may actually decrease. Some features of the site may not work correctly. Exploring the Associations Between Question Characteristics, Respondent Characteristics, Interviewer Performance Measures, and Survey Data Quality. Interdental CAL is detectable at ≥2 non‐adjacent teeth, or, Buccal or oral CAL ≥3 mm with pocketing >3 mm is detectable at ≥2 teeth. One approach has been the assessment of bone loss in relation to patient age by measuring radiographic bone loss in percentage of root length divided by the age of the patient. IV. Risk factor analysis is used as grade modifier. Peri‐implant mucositis sites with suppuration have higher microbial risk than sites without suppuration. Evidence-based, personalised and minimally invasive treatment for periodontitis patients - the new EFP S3-level clinical treatment guidelines. The paper describes a simple matrix based on stage and grade to appropriately define periodontitis in an individual patient. Update of the case definitions for population-based surveillance of periodontitis. Staging and grading do not help the practitioner arrive at a diagnosis. The stage is characterized by the presence of deep periodontal lesions that extend to the middle portion of the root and whose management is complicated by the presence of deep intrabony defects, furcation involvement, history of periodontal tooth loss/exfoliation, and presence of localized ridge defects that complicate implant tooth replacement.
