This paper proposes that periodontitis staging and grading should be used in dental implant therapy as a means to ensure maximum … In recent decades, attempts to classify periodontitis have centered on a dilemma represented by whether phenotypically different case presentations represent different diseases or just variations of a single disease. The diagnostic classification presented in Table 3 provides definitions for four stages of periodontitis. An individual case may thus be defined by a simple matrix of stage at presentation (severity and complexity of management) and grade (evidence or risk of progression and potential risk of systemic impact of the patient's periodontitis; these also influence the complexity of management of the case). A review of recent research on Theileria parva: Implications for the infection and treatment vaccination method for control of East Coast fever. Explicit designation of case complexity factors helps to define levels of competence and experience that a case is likely to require for optimal outcomes. Marginal alveolar bone loss – a key secondary feature of periodontitis – is coupled with loss of attachment by inflammatory mediators. Dr. Greenwell reports no conflicts of interest. Any queries (other than missing content) should be directed to the corresponding author for the article. 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. 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 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. Influence of keratinized mucosa on the surgical therapeutical outcomes of peri‐implantitis. In most of successfully treated patients, complexity factors that might have contributed to baseline staging will have been resolved through treatment. Periodontitis staging should assist clinicians in considering all relevant dimensions that help optimize individual patient management and thus represents a critical step towards personalized care (or precision medicine). Association between periodontal disease, tooth loss and liver diseases risk. Direct evidence is based on longitudinal observation available for example in the form of older diagnostic quality radiographs. The importance of this criteria has been well recognized in the 1989 AAP classification that identified a rapidly progressing form of periodontitis.43 Concern about this criterion has been mostly on how to assess the rate of progression at initial examination in the absence of direct evidence (e.g. One of the most important aspects for a classification system is to properly account for variability in the rate of progression of periodontitis. 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. While not ideal – as it requires significant disease at an early age or minimal disease at advanced age – this concept has been used in clinical practice and risk assessment tools to identify highly susceptible or relatively resistant individuals. As I work in private practice, I am finding that not everyone is on board with the new classification process yet. In using the table, it is important to use CAL as the initial stage determinant in the severity dimension. Table 4 illustrates periodontitis grading based on primary criteria represented by the availability of direct or indirect evidence of periodontitis progression. If you do not receive an email within 10 minutes, your email address may not be registered, 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). Influence of Myeloperoxidase Levels on Periodontal Disease: An Applied Clinical Study. 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. Irish Journal of Medical Science (1971 -). 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. The concept and value of “staging” has been extensively developed in the oncology field. This information is critical for precision medicine but has been an elusive objective to achieve in clinical practice.

Steps to Use the American Academy of Periodontology Staging and Grading Step 1: Assessment Up-to-date full mouth radiographs Up-to-date comprehensive periodontal exam (CPE) 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. 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.

Diagnostic and Prognostic ability of salivary MMP‐9 and S100A8 for periodontitis. Clinical diagnosis needs to be more all‐encompassing in expressing the effects of periodontitis and should account not only for the oral effects but also for potential systemic implications of the disease. It also provides the necessary framework for introduction of biomarkers in diagnosis and prognosis. Antiseptics as adjuncts to scaling and root planing in the treatment of periodontitis: a systematic literature review. Assessment of salivary biomarkers and/or new imaging technologies may increase early detection of stage I periodontitis in a variety of settings. 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. The systemic inflammatory response following hand instrumentation versus ultrasonic instrumentation—A randomized controlled trial. At the end of 2017, the American Academy of Periodontology released a new classification of Periodontal and Peri-Implant Diseases and Conditions. Authors were assigned the task to develop case definitions for periodontitis in the context of the 2017 World Workshop on the Classification of Periodontal and Peri‐Implant Diseases and Conditions. The 1999 group consensus report on aggressive periodontitis identified specific features of this form of disease and proposed the existence of major and minor criteria for case definition as well as distribution features to differentiate localized from generalized forms of periodontitis.8 By default, cases of periodontitis that would not satisfy the “aggressive” phenotype definition would be classified as “chronic” with the implication that latter cases could be managed more easily and, with appropriate therapy and maintenance care, would rarely jeopardize the retention of a functional dentition.9 The rationale for differentiating between chronic and aggressive periodontitis included the ability to identify and focus on the more problematic cases: presenting with greater severity earlier in life, at higher risk of progression and/or in need of specific treatment approaches. Periodontitis grade can then be modified by the presence of risk factors. Reflex gastroesophageal disorders and functional dyspepsia: Potential confounding variables for the progression of chronic periodontitis: A clinical study. 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. Analysis of Endothelin-1 Concentrations in Individuals with Periodontitis. As such, patients with stage I periodontitis have developed periodontitis in response to persistence of gingival inflammation and biofilm dysbiosis. Gender-Associated Oral and Periodontal Health Based on Retrospective Panoramic Radiographic Analysis of Alveolar Bone Loss. 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. 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. Identification of a patient as a periodontitis case, Identification of the specific form of periodontitis, and. The manuscript discusses the merits of a periodontitis case definition system based on Staging and Grading and proposes a case definition framework. Number of times cited according to CrossRef: Association between periodontitis and systemic medication intake: A case‐control study. Indirect evidence is based on the assessment of bone loss at the worst affected tooth in the dentition as a function of age (measured as radiographic bone loss in percentage of root length divided by the age of the subject). Co‐edited by Kenneth S. Kornman and Maurizio S. Tonetti. Updates include staging and grading system for periodontitis; classification of peri-implant diseas e. CHICAGO (June 21, 2018) — The American Academy of Periodontology (AAP) has published the official proceedings from the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions.

American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP). At present, relevant data are available to assess the two dimensions of the staging process: severity and complexity. 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. Saleh, Lucio Lo Russo, Henry Greenwell, William V. Giannobile, Hom‐Lay Wang, Development of a nomogram for the prediction of periodontal tooth loss using the staging and grading system: A long‐term cohort study, Journal of Clinical Periodontology, 10.1111/jcpe.13362, 47, 11, (1362-1370), (2020). 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. And the powerful outcome of that multidimensional view is the ability to communicate better with patients, other professionals, and third parties. 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. Current evidence suggests, however, that some individuals are more susceptible to develop periodontitis, more susceptible to develop progressive severe generalized periodontitis, less responsive to standard bacterial control principles for preventing and treating periodontitis, and theoretically more likely to have periodontitis adversely impact systemic diseases. Stage I periodontitis is the borderland between gingivitis and periodontitis and represents the early stages of attachment loss. Such multidimensional view of periodontitis would create the potential to transform our view of periodontitis. 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. The Protozoome of the Periodontal Sulcus: From Health to Disease. Learn about our remote access options, Periodontology, Faculty of Dentistry, University of Hong Kong, Hong Kong, SAR China. In spite of the possibility of tooth loss, masticatory function is preserved, and treatment of periodontitis does not require complex rehabilitation of function. The 1999 case definition system is also based on severity. III. 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. The primary criteria are either direct or indirect evidence of progression. Furthermore, the validity of many of the criteria for aggressive periodontitis has not been confirmed in adequately designed studies. Complexity factors may shift the stage to a higher level, for example furcation II or III would shift to either stage III or IV irrespective of CAL. 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.

Advancing Your Staging and Grading Framework for Periodontitis and Peri-implant Disease In 2017, the World Workshop, including the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP), created the new Classification of Periodontal and Peri-implant Diseases and Conditions. J Periodontal 2018;89 (Suppl 1): S159-S172. Furthermore, a uniform staging system should provide a way of defining the state of periodontitis at various points in time, can be readily communicated to others to assist in treatment, and may be a factor in assessing prognosis. 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. 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. Evidence for defining different stages based on CAL/bone loss in relation to root length is somewhat arbitrary. 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. 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. 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. an older diagnostic quality radiograph allowing comparison of marginal bone loss over time). The proposed framework allows introduction of validated biomarkers in the case definition system. Implementation of the novel 2017 American Academy of Periodontology (AAP) World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions (WWDC) diagnostic system for our clients with periodontitis and gingivitis allows us to optimize our diagnosis, care, and the communication of client needs. This approach was originally applied in a longitudinal assessment of disease progression assessed in intraoral radiographs68, 69 and was later incorporated in the theoretical concept that led to development of the periodontal risk assessment (PRA) system.31, 70 More recently, an individual's severity of CAL has been compared to his/her age cohort.16 This information from large and diverse populations could be considered an age standard for CAL, with the assumption that individuals who exceed the mean CAL threshold for a high percentile in the age cohort would be one additional piece of objective information that may represent increased risk for future progression.
