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. The four stages of periodontitis are based on the amount of damage that has already occurred. Diagnostic accuracy of periapical radiograph, cone beam computed tomography, and intrasurgical linear measurement techniques for assessing furcation defects: a longitudinal randomised controlled trial, Appendix A – Use of Staging and Grading Tables, Appendix B – Case Definitions for Specific Applications, Supplementary Table 1, Appendix A – Periodontitis Grade Example, First Published online: November 29, 2018. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors. The classification framework for periodontitis is based on a multidimensional staging and grading system that could be adapted over time as new evidence emerges. Assessment of salivary biomarkers and/or new imaging technologies may increase early detection of stage I periodontitis in a variety of settings. Disease severity at presentation/diagnosis as a function of patient age has also been an important indirect assessment of the level of individual susceptibility. The pathophysiology of the disease has been characterized in its key molecular pathways, and ultimately leads to activation of host‐derived proteinases that enable loss of marginal periodontal ligament fibers, apical migration of the junctional epithelium, and allows apical spread of the bacterial biofilm along the root surface. Effects of liraglutide on metabolic syndrome in WBN/Kob diabetic fatty rats supplemented with a high‐fat diet. Tooth‐related factors for tooth loss 20 years after active periodontal therapy–A partially prospective study. The role of bone markers. There is clinical value in individualizing the diagnosis and the case definition of a periodontitis patient to take into account the known dimension of the multifactorial etiology to improve prognosis, account for complexity and risk, and provide an appropriate level of care for the individual. Front Pharmacol. In such patients CAL and radiographic bone loss (RBL) will be the primary stage determinants. View all New Classification reports, guidelines, and videos. 2021 Jan 3:1-10. doi: 10.1007/s11282-020-00497-0. The proposed case definition BibTex; Full citation; Abstract. The 1999 workshop addressed a host of concerns with the clinical applicability and pathophysiologic rationale of previous classification systems (see Armitage 199910 for discussion), emphasized the need to capture differences between forms of the disease able to lead to edentulism, but did not clearly communicate differences between chronic and aggressive periodontitis. The other dimension not previously available in our classification is the directed identification of individual patients who are more likely to require greater effort to prevent or control their chronic disease long‐term. Risk factor analysis is used as grade modifier. Adjunctive local treatments for patients with residual pockets during supportive periodontal care: A systematic review and network meta‐analysis. In most of successfully treated patients, complexity factors that might have contributed to baseline staging will have been resolved through treatment. Conclusions: The paper describes a simple matrix based on stage and grade to ap‐ propriately define periodontitis in an individual patient. HbA1c, glycated hemoglobin; hsCRP, high sensitivity C‐reactive protein; PA, periapical; CAL, clinical attachment loss. For post‐treatment patients CAL and RBL are still the primary stage determinants. The vast majority of clinical cases of periodontitis do not have the local characteristics of necrotizing periodontitis or the systemic characteristics of a rare immune disorder with a secondary manifestation of periodontitis. 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. The systemic inflammatory response following hand instrumentation versus ultrasonic instrumentation—A randomized controlled trial.

Periodontal Disease and Targeted Prevention Using aMMP-8 Point-of-Care Oral Fluid Analytics in the COVID-19 Era. A notable exception is successful periodontal regeneration that may, through improvement of tooth support, effectively improve CAL and RBL of the specific tooth. 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). 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.

Effects of adjunctive probiotic L. reuteri lozenges on S/RSD outcomes at molar sites with deep pockets. Diabetes/Metabolism Research and Reviews. Staging is largely dependent upon the severity of disease at presentation as well as on the complexity of disease management, while grading provides supplemental information about biological features of the disease. Graetz C, Mann L, Krois J, Sälzer S, Kahl M, Springer C, Schwendicke F. J Clin Periodontol. Prof. Maurizio Tonetti, Periodontology, Faculty of Dentistry, University of Hong Kong, Prince Philip Dental Hospital 34, Hospital Road, Hong Kong, SAR China. The diagnosis for Periodontitis is now reported as a stage and grade. The proposed staging and grading of periodontitis provides an individual patient assessment that classifies patients by two dimensions beyond severity and extent of disease that identify patients as to complexity of managing the case and risk of the case exhibiting more progression and/or responding less predictably to standard periodontal therapy. Epub 2019 Jun 28. The Journal of the American Dental Association. Advancing Your Staging and Grading Framework for Periodontitis and Peri-implant Disease . For any given case only some, not all, complexity factors may be present, however, in general it only takes one complexity factor to shift the diagnosis to a higher stage. Such multidimensional view of periodontitis would create the potential to transform our view of 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. Simple enough to be clinically applicable but not simplistic: additional knowledge has distinguished dimensions of periodontitis, such as complexity of managing the case to provide the best level of care, Standardized to be able to support effective communication among all stakeholders, Accessible to a wide range of people in training and understood by members of the oral health care team around the world. This information is critical for precision medicine but has been an elusive objective to achieve in clinical practice. New technologies and therapeutic approaches to periodontitis management are now available such that clinicians with advanced training can manage patients with moderate and severe periodontitis to achieve clinical outcomes that were not previously possible.

J Periodontol. Microbiological and host-derived biomarker evaluation following non-surgical periodontal therapy with short-term administration of systemic antimicrobials: secondary outcomes of an RCT. 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. In recent years, validated risk assessment tools25, 67 and presence of individually validated risk factors65 have been associated with tooth loss, indicating that it is possible to estimate risk of periodontitis progression and tooth loss.

This relies on three sets of parameters: 1) rate of periodontitis progression; 2) recognized risk factors for periodontitis progression; and 3) risk of an individual's case affecting the systemic health of the subject. Since the 1999 workshop considerable evidence has emerged concerning potential effects of periodontitis on systemic diseases. If a stage‐shifting complexity factor(s) is eliminated by treatment, the stage should not retrogress to a lower stage since the original stage complexity factor should always be considered in maintenance phase management. Specific considerations for use of the staging and grading of periodontitis with epidemiological and research applications are discussed in Appendix B in the online Journal of Periodontology. Tooth loss attributable to periodontitis needs to be incorporated in the definition of severity. Periodontitis. The association of Tumor Necrosis factor alpha, Lymphotoxin alpha, Tumor Necrosis Factor Receptor 1 and Tumor Necrosis Factor Receptor 2 gene polymorphisms and serum levels with periodontitis and type 2 diabetes in Serbian population. Multiple periodontitis case definitions have been proposed in recent years. The primary criteria are either direct or indirect evidence of progression. Staging intends to classify the severity and extent of a patient’s disease based on a measurable amount of destroyed/damaged tissue from periodontitis. Grade of periodontitis is estimated with direct or indirect evidence of progression rate in three categories: slow, moderate and rapid progression (Grade A-C). 2020 Nov 9;11:588480. doi: 10.3389/fphar.2020.588480. Evaluation of serum and gingival crevicular fluid microRNA-223, microRNA-203 and microRNA-200b expression in chronic periodontitis patients with and without diabetes type 2. Epub 2019 Sep 25. Table 2 illustrates this concept and provides a general framework that will allow updates and revisions over time as specific evidence becomes available to better define individual components, particularly in the biological grade dimension of the disease and the systemic implications of periodontitis. The overall classification system aimed to differentiate the more common forms of periodontitis, i.e. At present, relevant data are available to assess the two dimensions of the staging process: severity and complexity. J Clin Periodontol. Learn about our remote access options, Periodontology, Faculty of Dentistry, University of Hong Kong, Hong Kong, SAR China. The position papers that addressed aggressive and chronic periodontitis reached the following overarching conclusions relative to periodontitis: A case definition system should facilitate the identification, treatment and prevention of periodontitis in individual patients. The CAL must be adjusted in some way based on number of missing teeth to avoid biasing the CAL based on measuring only remaining teeth after extraction of the teeth with the most severe periodontitis. Information on tooth loss that can be attributed primarily to periodontitis – if available – may modify stage definition. 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. The charts below provide an overview. Evaluation of salivary and serum asymmetric dimethylarginine (ADMA) levels in patients with periodontal and cardiovascular disease as subclinical marker of cardiovascular risk. If a stage shifting complexity factor(s) were eliminated by treatment, the stage should not retrogress to a lower stage since the original stage complexity factor should always be considered in maintenance phase management. Analysis of Endothelin-1 Concentrations in Individuals with Periodontitis. A Pilot Study Examining Vitamin C Levels in Periodontal Patients. Objective masticatory efficiency and subjective quality of masticatory function among patients with periodontal disease. One of the most important aspects for a classification system is to properly account for variability in the rate of progression of periodontitis. Whenever available, direct evidence is used; in its absence indirect estimation is made using bone loss as a function of age at the most affected tooth or case presentation (radiographic bone loss expressed as percentage of root length divided by the age of the subject, RBL/age). Differences in the periodontal microbiome of successfully treated and persistent aggressive periodontitis. 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. Lactobacillus reuteri associated with scaling and root planing in the treatment of periodontitis in rats submitted to chemotherapy. 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. Some clinical conditions other than periodontitis present with clinical attachment loss. 19998 for detailed discussion), the difficulty in applying the stipulated criteria in the everyday clinical practice and the substantial overlap between the diagnostic categories provided a barrier to clinicians in the application of the classification system. Chronic Periodontitis – Prevention, Diagnosis and Treatment: A Systematic Review [Internet]. Diese beruht zuerst einmal auf Informationen, die in der allgemeinen Anamnese, in der speziell zahnmedizinischen, in der Familien- und in der sozialen Anamnese erhoben werden. 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. Given current knowledge, a periodontitis case definition system should include three components: A patient is a periodontitis case in the context of clinical care if: Based on pathophysiology, three clearly different forms of periodontitis have been identified: A case definition system needs to be a dynamic process that will require revisions over time in much the same way the tumor, node, metastasis (TNM) staging system for cancer has been shaped over many decades. Working off-campus? Rationale of classification according to severity encompasses at least two important dimensions: complexity of management and extent of disease. Multiple observational studies in populations with long‐term exposure to microbial biofilms on the teeth have shown that a small segment of the adult population expresses severe generalized periodontitis and most express mild to moderate periodontitis.19, 20 It is also well documented using twin studies that a large portion of the variance in clinical severity of periodontitis is attributable to genetics.5, 6, 21, 22, It is reasonable to expect that future research advances will increase our knowledge of disease‐specific mechanisms in the context of the multifactorial biological interactions involved in specific phenotypes.
