tonetti staging and grading of periodontitis

Update of the case definitions for population-based surveillance of periodontitis. Systemic conditions and oral health‐related quality of life of pregnant women of normal weight and who are overweight. The correspondence of 3D supporting bone loss and crown‐to‐root ratio to periodontitis classification. Classification and diagnosis of aggressive periodontitis. These can be assessed in each individual case at diagnosis by appropriate anamnestic, clinical, and imaging data. There is evidence, however, that specific segments of the population exhibit different levels of disease progression, as indicated by greater severity of clinical attachment loss (CAL) in subsets of each age cohort relative to the majority of individuals in the age cohort. Background: Implementation of the new classification of periodontal diseases requires careful navigation of the new case definitions and organization of the diagnostic process along rationale and easily applicable algorithms. One of the most important aspects for a classification system is to properly account for variability in the rate of progression of periodontitis. Adjunctive effect of systemic antimicrobials in periodontitis therapy: A systematic review and meta‐analysis. Evidence-based, personalised and minimally invasive treatment for periodontitis patients - the new EFP S3-level clinical treatment guidelines. 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. The bacterial biofilm formation initiates gingival inflammation; however, periodontitis initiation and progression depend on dysbiotic ecological changes in the microbiome in response to nutrients from gingival inflammatory and tissue breakdown products that enrich some species and anti‐bacterial mechanisms that attempt to contain the microbial challenge within the gingival sulcus area once inflammation has initiated. 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. 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. Risk factor analysis is used as grade modifier. There is no evidence of specific pathophysiology that enables differentiation of cases that would currently be classified as aggressive and chronic periodontitis or provides guidance for different interventions. Evidence-based, personalised and minimally invasive treatment for periodontitis patients - the new EFP S3-level clinical treatment guidelines. The workshop was planned and conducted jointly by the American Academy of Periodontology and the European Federation of Periodontology with financial support from the American Academy of Periodontology Foundation, Colgate, Johnson & Johnson Consumer Inc., Geistlich Biomaterials, SUNSTAR, and Procter & Gamble Professional Oral Health. A systematic review and meta-analysis. In addition to reports that were prepared prior to the World Workshop, there were 4 working groups at the meeting and each issued a consensus report at the conclusion of the meeting. Staging of tumors is based on current observable clinical presentation including size or extent and whether it has metastasized. Emerging functions and clinical applications of exosomes in human oral diseases. PERIODONTITIS: STAGING . At the moment there is insufficient evidence to consider that periodontitis observed in poorly controlled diabetes is characterized by unique pathophysiology and/or requires specific periodontal treatment other than the control of both co‐morbidities.18. The proposed risk stratification is based on well‐validated risk factors including smoking, uncontrolled Type II diabetes, clinical evidence of progression or disease diagnosis at an early age, and severity of bone loss relative to patient age. Treatment of Stage I-III Periodontitis -The EFP S3 Level Clinical Practice Guideline. Advances in Questionnaire Design, Development, Evaluation and Testing. 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. 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. In the context of the 2017 World Workshop, it is suggested that a single definition be adopted. For example, in case of very short common root trunk a CAL of 4 mm may have resulted in class II furcation involvement, hence shifting the diagnosis from stage II to stage III periodontitis. 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. 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. The manuscript discusses the merits of a periodontitis case definition system based on Staging and Grading and proposes a case definition framework. Analysis of Porphyromonas gingivalis fimA genotypes in severe periodontitis patients.

A nomogram prediction for mandibular molar survival in Chinese patients with periodontitis: A 10‐year retrospective cohort study. 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. 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. Staging relies on the standard dimensions of severity and extent of periodontitis at presentation but introduces the dimension of complexity of managing the individual patient. Explicit designation of case complexity factors helps to define levels of competence and experience that a case is likely to require for optimal outcomes. 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. IV. At the more advanced stage IV, periodontitis causes considerable damage to the periodontal support and may cause significant tooth loss, and this translates to loss of masticatory function. An indicator of periodontal stability, Bleeding on probing. Description of the clinical presentation and other elements that affect clinical management, prognosis, and potentially broader influences on both oral and systemic health. At present, relevant data are available to assess the two dimensions of the staging process: severity and complexity. International Journal of Chronic Obstructive Pulmonary Disease. The number of affected teeth (as a percentage of teeth present) has been used to define cases of chronic periodontitis in the 1999 classification9, 10 while the distribution of lesions (molar incisor versus generalized pattern of breakdown) has been used as a primary descriptor for aggressive periodontitis.8, 28 Rationale for keeping this information in the classification system comes from the fact that specific patterns of periodontitis (e.g. 2 mm) to address measurement error with CAL detection with a periodontal probe would result in misclassification of initial periodontitis cases as gingivitis. Factors such as probing depths,36 type of bone loss (vertical and/or horizontal),37 furcation status,38 tooth mobility,39-41 missing teeth, bite collapse,42 and residual ridge defect size increase treatment complexity and need to be considered and should ultimately influence diagnostic classification. 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. In addition, current molecular markers often guide selection of specific drug therapies, and thereby incorporate biological targets that increase the granularity of the grade and thus may increase the probability of a favorable clinical outcome. While the consensus report of the aggressive periodontitis working group articulated major and minor criteria required for the aggressive periodontitis diagnosis as well as specific definitions to identify patterns of distribution of lesions within the dentition (localized molar incisor versus generalized, see Lang et al. Staging intends to classify the severity and extent of a patient’s disease based on the measurable amount of destroyed and/or damaged tissue as a result of periodontitis and to assess the specific factors that may attribute to the complexity of long-term case management. Only attachment loss attributable to periodontitis is used for the score. Self‐reported illness perception and oral health‐related quality of life predict adherence to initial periodontal treatment. Do patients with aggressive and chronic periodontitis exhibit specific differences in the subgingival microbial composition? As disease severity increases, CAL is more firmly established, and a periodontitis case can be identified with greater accuracy. Working off-campus? 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. The addition of grade may be achieved by refining each individual's stage definition with a grade A, B, or C, in which increasing grades will refer to those with direct or indirect evidence of different rates of periodontal breakdown and presence and level of control of risk factors. Do the clinical criteria used to diagnose periodontitis affect the association with prematurity?. Prof. Maurizio Tonetti, Periodontology, Faculty of Dentistry, University of Hong Kong, Prince Philip Dental Hospital 34, Hospital Road, Hong Kong, SAR China. The proposed case definition does not stipulate a specific threshold of detectable CAL to avoid misclassification of initial periodontitis cases as gingivitis and maintain consistency of histological and clinical definitions. 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. Figure 2. Application of weighted gene co-expression network analysis to reveal key modules and hub genes in generalized aggressive periodontitis. 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. Periodontitis definitions based on marginal radiographic bone loss suffer from severe limitations as they are not specific enough and miss detection of mild to moderate periodontitis.27 Periodontitis definitions based on radiographic bone loss should be limited to the stages of mixed dentition and tooth eruption when clinical attachment level measurement with reference to the CEJ are impractical.28 In such cases periodontitis assessments based on marginal radiographic bone loss may use bitewing radiographs taken for caries detection. Periodontal health and gingival diseases and conditions on a… Mechanical plaque removal of periodontal maintenance patients: A systematic review and network meta‐analysis. Group C consensus report of the 5th European Workshop in Periodontology, Periodontal regeneration versus extraction and prosthetic replacement of teeth severely compromised by attachment loss to the apex: 5‐year results of an ongoing randomized clinical trial, Long‐term effect of surgical/non‐surgical treatment of periodontal disease, The angular bony defect as indicator of further alveolar bone loss, Tooth loss in molars with and without furcation involvement ‐ a systematic review and meta‐analysis, Tooth mobility and the biological rationale for splinting teeth, Prognosis versus actual outcome. 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 previously types of periodontitis recognised as “chronic” or “aggressive” are now grouped under a single category of “periodontitis”. An interdisciplinary approach to the management of a young patient with generalized periodontitis – A case report with a 3-year follow-up. International Journal of Environmental Research and Public Health. The level of oral biofilm contamination of the dentition also influences the clinical presentation. See this chart from the AAP on staging and grading of periodontal disease. Patients who have been treated for periodontitis may be periodically staged to monitor them. Burt and Eklund's Dentistry, Dental Practice, and the Community. Periodontitis and airflow limitation in older Swedish individuals. In using the table, it is important to use CAL as the initial stage determinant in the severity dimension. Necrotizing periodontitis is characterized by history of pain, presence of ulceration of the gingival margin and/or fibrin deposits at sites with characteristically decapitated gingival papillae, and, in some cases, exposure of the marginal alveolar bone. Periodontitis as a direct manifestation of systemic diseases. 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. 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. The New Periodontal classification system has a staging and grading system - instead of the previously used Case Types or descriptive severity. J Periodontol 2018;89 (Suppl 1): S159-S172. The classification of periodontitis was modified to recognize three forms of periodontitis: necrotizing periodontitis, periodontitis as a manifestation of systemic disease, and a single category of periodontitis with staging and grading criteria as presented in Table 2. In the absence of proper control of the periodontitis and adequate rehabilitation, the dentition is at risk of being lost. However, if other factors are present in the complexity dimension that influence the disease then modification of the initial stage assignment may be required. The proceedings of the workshop were jointly and simultaneously published in the Journal of Periodontology and Journal of Clinical Periodontology. Journal of Oral Biology and Craniofacial Research. 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. Stage I periodontitis is the borderland between gingivitis and periodontitis and represents the early stages of attachment loss. proposed the staging and grading for periodontal diseases according to a framework replicating the oncology staging criteria proposed goals for the staging and grading for periodontitis patients. The proposed staging and grading explicitly acknowledges the potential for some cases of periodontitis to influence systemic disease. Evidence linking the role of periodontal viruses in coronary artery disease with and without periodontitis. Periodontitis phenotypes and clinical response patterns to non‐surgical periodontal therapy: reflections on the new periodontitis classification. 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. Is There a Bidirectional Association between Polycystic Ovarian Syndrome and Periodontitis? Frequently, case management requires stabilization/restoration of masticatory function. 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.
