Using periodontal staging and grading system as a prognostic factor for future tooth loss: A long-term retrospective study J Periodontol. Authors Maurizio S Tonetti 1 , Henry Greenwell 2 , Kenneth S Kornman 3 Affiliations 1 Periodontology, Faculty of Dentistry, University of Hong Kong, Hong Kong, SAR China. The proposed staging and grading is designed to avoid the paradox of improvement of disease severity observed after loss/extraction of the more compromised teeth. Disease severity at presentation/diagnosis as a function of patient age has also been an important indirect assessment of the level of individual susceptibility. Evaluation of salivary and serum asymmetric dimethylarginine (ADMA) levels in patients with periodontal and cardiovascular disease as subclinical marker of cardiovascular risk. Explicit designation of case complexity factors helps to define levels of competence and experience that a case is likely to require for optimal outcomes. Expression of inflammatory biomarkers and growth factors in gingival crevicular fluid at different healing intervals following non‐surgical periodontal treatment: A systematic review. 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. 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. Periodontitis grade can then be modified by the presence of risk factors. 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.

The official proceedings from the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions, co-presented by the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP), are now available online as a supplement to the June 2018 issue of the Journal of Periodontology. Periodontitis as a direct manifestation of systemic diseases. The occurrence of periodontal diseases and its correlation with different risk factors among a convenient sample of adult Egyptian population: a cross-sectional study. Helicobacter pylori first‐line and rescue treatments in patients allergic to penicillin: Experience from the European Registry on H pylori management (Hp‐EuReg). The paper describes a simple matrix based on stage and grade to appropriately define periodontitis in an individual patient. 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. Reflex gastroesophageal disorders and functional dyspepsia: Potential confounding variables for the progression of chronic periodontitis: A clinical study. For post‐treatment patients CAL and RBL are still the primary stage determinants. Expression Levels of A Disintegrin-like Metalloproteinase with Thrombospondin Motifs-4 and -5 (ADAMTS-4 and ADAMTS-5) in Inflamed and Healthy Gingival Tissues. 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. Grade of periodontitis is estimated with direct or indirect evidence of progression rate in three categories: slow, moderate and rapid progression (Grade A‐C). A clinical periodontal assessment pro forma incorporating the new periodontal classification. 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. In the various contexts, case definitions may require different diagnostic characteristics based on the objectives of the specific application, as is discussed below. Does Cultural Difference Affect Investment–Cash Flow Sensitivity? Evidence comes from: i) a distinct pathophysiology characterized by prominent bacterial invasion and ulceration of epithelium; ii) rapid and full thickness destruction of the marginal soft tissue resulting in characteristic soft and hard tissue defects; iii) prominent symptoms; and iv) rapid resolution in response to specific antimicrobial treatment. However, if other factors are present in the complexity dimension that influence the disease then modification of the initial stage assignment may be required. These can be assessed in each individual case at diagnosis by appropriate anamnestic, clinical, and imaging data. Various mechanisms linking periodontitis to multiple systemic diseases have been proposed.45, 46 Specific oral bacteria in the periodontal pocket may gain bloodstream access through ulcerated pocket epithelium. 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. In spite of the possibility of tooth loss, masticatory function is preserved, and treatment of periodontitis does not require complex rehabilitation of function. Periodontal regeneration by leukocyte and platelet‐rich fibrin with autogenous bone graft versus enamel matrix derivative with autogenous bone graft in the treatment of periodontal intrabony defects: A randomized non‐inferiority trial. 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. Lactobacillus reuteri associated with scaling and root planing in the treatment of periodontitis in rats submitted to chemotherapy.

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). It should be noted that periodontal inflammation, generally measured as bleeding on probing (BOP), is an important clinical parameter relative to assessment of periodontitis treatment outcomes and residual disease risk post‐treatment.29-32 However BOP itself, or as a secondary parameter with CAL, does not change the initial case definition as defined by CAL or change the classification of periodontitis severity. Identification of a patient as a periodontitis case, Identification of the specific form of periodontitis, and. The initial stage should be determined using CAL; if not available then RBL should be used. Case‐control47-50 and pilot intervention studies51, 52 show that periodontitis contributes to the overall inflammatory burden of the individual which is strongly implicated in coronary artery disease, stroke, and Type II diabetes.53-58 Initial evidence also supports the potential role of the overall systemic inflammatory burden on the risk for periodontitis.59. It should be emphasized that these case definitions are guidelines that should be applied using sound clinical judgment to arrive at the most appropriate clinical diagnosis. Association between periodontal disease, tooth loss and liver diseases risk. 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. The proceedings of the workshop were jointly and simultaneously published in the Journal of Periodontology and Journal of Clinical Periodontology. The proposed staging and grading explicitly acknowledges the potential for some cases of periodontitis to influence systemic disease.

Development of a nomogram for the prediction of periodontal tooth loss using the staging and grading system: A long‐term cohort study. Number of times cited according to CrossRef: Association between periodontitis and systemic medication intake: A case‐control study. The proposed case definition extends beyond description based on severity to include characterization of biological features of the disease and represents a first step towards adoption of precision medicine concepts to the management of periodontitis. Methods Thirty participants (10 periodontal experts, 10 general dentists and 10 undergraduate students) and a gold‐standard examiner were asked to classify 25 fully documented periodontitis cases twice. Adjunctive local treatments for patients with residual pockets during supportive periodontal care: A systematic review and network meta‐analysis. At this stage of the disease process, however, management remains relatively simple for many cases as application of standard treatment principles involving regular personal and professional bacterial removal and monitoring is expected to arrest disease progression. Important limitations of severity definitions are worth discussing also in the context of recent therapeutic improvements that have enabled successful management of progressively more severe periodontitis.35 Conventional definitions of severe periodontitis need to be revised to better discriminate the more severe forms of periodontitis. The systemic inflammatory response following hand instrumentation versus ultrasonic instrumentation—A randomized controlled trial. Proceedings of the World Workshop in Clinical Periodontics. This is the case even in the absence of complexity factors. The “Three Steps to Staging and Grading a Patient ...

Application of the In Vitro HoxB8 Model System to Characterize the Contributions of Neutrophil–LPS Interaction to Periodontal Disease. Clinical presentation differs based on age of patient and lesion number, distribution, severity, and location within the dental arch. 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. Irish Journal of Medical Science (1971 -). Applied Psychology: Health and Well-Being. It is suggested that a case definition based on a matrix of periodontitis stage and periodontitis grade be adopted. Clinicians should initially assume grade B disease and seek specific evidence to shift to grade A or C. Risk of preterm birth associated with maternal gingival inflammation and oral hygiene behaviours in rural Nepal: a community-based, prospective cohort study. Multiple periodontitis case definitions have been proposed in recent years. 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. 2 mm) to address measurement error with CAL detection with a periodontal probe would result in misclassification of initial periodontitis cases as gingivitis.

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.

Effect of sodium ascorbyl phosphate on osteoblast viability and differentiation. 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. This has been another episode of Fast Facts - Perio Edition with Katrina Sanders, RDH.

Gender-Associated Oral and Periodontal Health Based on Retrospective Panoramic Radiographic Analysis of Alveolar Bone Loss. Active gingival inflammation is linked to hypertension. The manuscript discusses the merits of a periodontitis case definition system based on Staging and Grading and proposes a case definition framework. 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. Relationship of periodontitis and edentulism to angiographically diagnosed coronary artery disease: A cross‐sectional study. It is recognized that in clinical practice application some clinicians may prefer to use diagnostic quality radiographic imaging as an indirect and somehow less sensitive assessment of periodontal breakdown. 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. Such multidimensional view of periodontitis would create the potential to transform our view of periodontitis. Dr. Kornman was previously employed by Interleukin Genetics, which has patents covering genetic patterns in periodontal disease. They represent more than just an early diagnosis: if they show a degree of clinical attachment loss at a relatively early age, these patients may have heightened susceptibility to disease onset. 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. Increasing the threshold, requiring CAL at ≥1 site, and excluding causes of CAL, other than periodontitis, increases specificity.
