These include classification by Fish 1944 22, Goldman et al. This classification was accepted by the American Academy of Periodontology (AAP) and gained wide acceptance. Prepubertal, juvenile (localized and generalized), adult, rapidly progressive. Another important change was replacement of “Necrotizing Ulcerative Periodontitis” with “Necrotizing Periodontal Diseases”. Open in figure viewer PowerPoint. from the classification system developed at the 1989 World Workshop in Clinical Periodontics.1 In addition, an analysis of the rationale is provided for each of the modifications and changes. Many researchers at that time proposed that these diseases are caused by local factors, This paradigm was dominated by the pathology of the disease process. Highfield J. This system is based on loss of attachment. Their research work showed that host response is an important factor in determining the disease progression and its outcome. 1999 Dec;4(1):1-6. Classification of periodontal diseases and conditions. The 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions was co-presented by the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP). (1986) 2 on the natural history of periodontal disease, where they observed the progression of periodontal diseases naturally without interfering. Adult Attachment Projective Picture System (AAP) Developed by Carol George and Malcolm West in 1999, this is a free response task that involved telling stories in response to eight picture stimuli (1 warm-up & 7 attachment scenes). If the AAP has not re-classified periodontitis since 1999, there is a good chance it will be at least ten or twenty years before we have new guidelines. Armitage GC. Chronic periodontitis

So, a new term. https://dimensionsofdentalhygiene.com/know-about-classification-system The term Schmutz-Pyorrhӧea was used to describe a periodontal condition that was caused due to the accumulation of deposits on the teeth, leading to inflammation, shallow pockets, and resorption of the alveolar crest. This novel system aims to use client-centered data to assign a stage and grade that may provide a more individualized periodontal care and risk assessment. 4-4B: AAP classification of periodontitis and other periodontal conditions, p. 79. At that time, there was a little knowledge about the etiopathogenesis of the diseases. Especially, ‘rapidly progressive periodontitis’ was a heterogeneous category. Necrotizing ulcerative gingivitis (NUG) and necrotizing ulcerative periodontitis (NUP) were clinically distinguishable disease entities but it was unclear that whether they were a part of the same disease process or were two distinct diseases. So, half the job is done. The mouth of the patient is foul-smelling. Cumulative Final First Term Learn with flashcards, games, and more — for free. Periodontology 2000. 1 New technology, research, and information has emerged in the past 18 years which led to the new revisions. Diseases are classified to simplify our understanding regarding different diseases in a particular medical or dental field. Generally, diseases are classified according to their etiology into different classes like, inflammatory, congenital, genetic, neoplastic, acquired, etc. Objective. September 01, 1999 : Vol. A good description can be found in George and West's 1999 paper in the journal Attachment and Human Development. On October 30–November 2, 1999, the International Workshop for a Classification of Periodontal Diseases and Conditions was held and a new classification was agreed upon (Fig. Research indicates that 80% of North American adults have some form of periodontal disease, while evidence also indicates that there is a link between oral and systemic health. Periodontitis complex was caused secondary to periodontosis, having similar etiological factors to periodontitis and little or no calculus and was considered as a degenerative disease. (adsbygoogle = window.adsbygoogle || []).push({}); The initial workers on periodontal diseases did not specify any particular terminology for these conditions, until Fauchard (1723) 3, who used the term “scurvy of the gums”, for the first time. Page and Schroeder in 1982 32 proposed a new classification system which was based on infection/host response paradigm. The periodontal destruction is rapid which gradually slows down spontaneously. ), tooth type and furcation involvement, species and strains of microflora, degree of host response (particularly immune response), and whether the patient smokes make it difficult to classify a patient as a refractory periodontitis patient. 1999 – chronic, aggressive (localized and generalized), necrotizing and as a manifestation of sytemic disease, … Presence ⁄ absence of clinically detectable inflammation. So, a new term “aggressive periodontitis” was introduced for this condition because the earlier term was too restrictive. These classification systems were based on the ‘principles of general pathology’ as presented by Orban et al. The disease is usually treatable by routine non-surgical and surgical periodontal therapy. Non-plaque-induced gingival lesions

A new periodontal disease classification system was recom-mended by the 1999 International Workshop for a Classification of Periodontal Disease and Conditions2 (Table 2) and has been accepted by the AAP. In 1999 an international workshop for classification of periodontal diseases and conditions was held at Oak Brook (Illinois, USA), in which a group of internationally acknowledged experts produced a generally accepted and scientifically founded classification of periodontal diseases 40. Their observations showed that the natural history of periodontal disease, in some but not all patients, results in tooth loss. Ann Periodontol 1999;4:1-6. In the next article we shall read the recent 2017 classification system for classifying periodontal and peri-implant diseases and conditions. Almost all the classification systems given during this period used terms like atrophic, degenerative, dystrophic etc. In active disease, the gingiva is acutely inflamed with marginal proliferation, whereas in inactive disease gingiva may appear completely normal. Periodontology 2000. Alveolar atrophy or diffuse atrophy was described as a noninflammatory disease in which minimal local factors, i.e. In 2017, both the American Academy of Periodontology (AAP) and the European Federation of Periodontology at the World Workshop updated the 1999 guidelines and classifications for diagnosing periodontal disease and developed new classifications for peri-implant diseases. In 1999, the American Academy of Periodontology significantly revised their guidelines for periodontal disease classifications. The information presented in this website has been collected from various leading journals, books and websites. It is very complete, detailed and complex and perhaps does not lend itself for use in its entirety on a daily basis by practitioners. The severity of the disease is categorized as Slight (1-2mm of loss of attachment), Moderate (3-4mm … 2002 Oct;30(1):9-23. Ranney RR. Here, the age of onset of the disease was described as usually 30 to 35 years and older. There was considerable overlap between different categories within the classification system. Adult periodontitis category in 1989 classification was designated for patients more than 35 years of age, having a slow rate of disease progression and periodontal destruction consistent with the presence of local factors.

A. Wound Healing and Dental Therapies: Repair and Regeneration Article This paradigm was dominated by the pathology of the disease process. These were initial classification systems proposed solely on the basis of clinical features of the disease. VIII. Ann Periodontol 1999;4(11):1-6. AAP member periodontists are specialists in periodontal disease treatment, cosmetic periodontal procedures, and dental implant placement. One major drawback of this classification was that it was heavily depended upon the age of the patient. Classification of periodontal diseases. This condition was described as of circumpubertal origin where the diagnosis was usually made at an age beyond puberty. AAP . The authors were charged with updating the 1999 classification of periodontal diseases and conditions 1 and developing a similar scheme for peri‐implant diseases and conditions. 104, Issue Supplement 4: 647-860 The Therapeutic Orphan 30 Years Later September 01, 1999 : Vol. They can be accessed as a special virtual issue on the AAP Clinical and Scientific Papers page.

The 1999 AAP Classification 28 is encyclopaedic. AAP world workshop 1999 Classification of Periodontal Diseases and Conditions. The simplified classification is as follows. 104 , Issue Supplement 3 : 581-645 Although it is a fact that this condition is commonly found in people under 35 years of age, but it may also affect older patients. By now you would have seen or heard of the new classification of periodontal and peri-implant diseases, which replaced the previous (1999) classification system and addressed most of its limitations. In 2018, the official proceedings of the American Academy of Periodontology (AAP) World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions (WWDC) were published. 5. The initial classification systems were based on the clinical features of the diseases (1870-1920), then came the concepts of classical pathology (1920-1970), and presently we are following the concepts of infectious etiology of periodontal diseases and host response (1970-present) 1. In this classification five distinctly different forms of periodontitis were described. In this classification periodontitis was classified into two categories simplex and complex. As our present knowledge about the pathogenesis of periodontal diseases suggests that there are many factors that affect the disease progression and its response to the treatment, category “Refractory Periodontitis” was eliminated as a separate entity in the new classification. The understanding of the historical aspect of the classification systems is essential to understand the presently used classification. Classification did not include gingivitis or gingival disease category. Another drawback was, the age at which a patient presents for the treatment does not necessarily reflect the age at which the disease began. Development of a classification system for periodontal diseases and conditions. It not only simplifies our understanding regarding the diseases but also facilitates communication. The accumulation of plaque is consistent with periodontal destruction. Paradental-Pyorrhӧea was characterized by irregularly distributed pockets varying from shallow to extremely deep. A chronic periodontitis case may have periods of rapid periodontal breakdown and during this period the case may mimic an aggressive periodontitis case. Periodontology [AAP], 1989; AAP, 1999). Finally, dental implants have become an inseparable part of periodontics but implant-associated diseases have not been classified in the 1999 classification system. 1993 Jun;2(1):13-25. ( Log Out /  Classification of diseases also helps us to communicate, for example, if I say a patient is suffering from generalized periodontitis Stage III, Grade C, you shall have an idea about all the clinical signs and symptoms of the disease and present periodontal status of the patient. IV. 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. Papers. You may read AAP "Development of a Classification System for Periodontal Diseases and Conditions" ; Annals of Periodontology, Volume 4 Classification article for helpful details. Australian dental journal. The refractory periodontitis was also a heterogeneous category as the criteria for this condition were difficult to relate clinically while placing the patient in this category. Further, AAP at the World Workshop in Clinical Periodontics at Princeton in 1989 33 amended the classification system with a few refinements. Although these cases are common at the age 35 years or more, but this condition can be seen in adolescents and even in the primary dentition of children. Lesions are primarily around permanent first molars and/or incisors with the usually symmetrical distribution. Periodontitis associated with endodontic lesions indicate periodontic-endodontic lesions in which there are both periodontic and endodontic components. 2005 Oct;39(1):13-21. Disease names which last with, The initial workers on periodontal diseases did not specify any particular terminology for these conditions, until, These were initial classification systems proposed solely on the basis of clinical features of the disease. 6. In 1989 classification, early-onset periodontitis category consisted of patients having significant attachment loss in the presence of little local factors (plaque and calculus) and age less than 35 years. In 1999, yet another reclassification of the periodontal diseases and conditions occurred. For the 2018 classification, patients were staged according to their CAL or … In the following sections, we shall study why many classification systems were proposed, their drawbacks and finally the classification system that we are following presently. Almost all the classification systems given during this period used terms like atrophic, degenerative, dystrophic etc. At that time, there was a little knowledge about the etiopathogenesis of the diseases. The primary purpose of a classification system is to systematically classify the diseases into various categories. Purpose and problems of periodontal disease classification. Secondly, a new identification and classification system of periodontitis has been defined. So, a new term “Necrotizing Periodontal Diseases” was used for these conditions. Some researchers suggested that local factors are responsible for the diseases, but in some cases systemic factors also play an important role 13-15. This new classification has numerous subcategories; only the major categories will be discussed here. Classifying periodontal diseases–a long‐standing dilemma. Armitage GC. Chicago: The American Academy of Periodontology, 1‐22. So, based on these factors this category was discontinued. 1968 25. A new classification scheme for periodontal and peri‐implant diseases and conditions – Introduction and key changes from the 1999 classification Jack G. Caton Gary Armitage Clinically gingiva appears completely normal with minimal local factors. Diagnosis and classification of periodontal disease. A new periodontal disease classification system was recommended by the 1999 International Workshop for a Classification of Periodontal Disease and Conditions2. These conditions were added to the classification system as such without any change in their definitions. During this time period, due to relatively fewer publications and lack of appropriate interactions between different schools of thoughts, researchers individually put forward their point of view regarding the classification of periodontal diseases. Painful form of gingivitis: This condition is presently known as necrotizing ulcerative gingivitis (NUG) which is a painful condition with necrosis of gingiva and tooth-supporting structures. A more convenient and simplified summary is: Figure 2. Periodontitis associated with endodontic lesions. In this condition the calculus deposition was associated with an even or generalized pattern of destruction of alveolar bone which progressed through a long duration of time. Van Der Velden U. In the 1999 classification, the guidelines for differ-entiating localized versus generalized disease are based on the percentage of affected sites. 4-4A: AAP classification of gingival diseases, p. 78. ( Log Out /  It is normally referred to as IWCP 1999 classification but also as the AAP 1999 classification. All papers are free access. Let’s embrace the “change!” The American Academy of Periodontology Classifications are created to … The first widely accepted classification system was given by Gottlieb, who classified periodontal diseases into four types 18-20. The American Academy of Periodontology’s (AAP) 1999 classification system was based on an infection and host response model. Most of the patients have neutrophil and monocyte function defects. Now we can elaborate the disease by going into detailed clinical and radiographic examination of the patient. Since then, researchers have introduced names for diseases of the periodontium on the basis of etiologic factors, pathologic changes or clinical manifestations. 4-2: Main categories: AAP classification of periodontal diseases and conditions, 1999, p. 77. In 1989 classification, early-onset periodontitis category consisted of patients having significant attachment loss in the presence of little local factors (plaque and calculus) and age less than 35 years. In the generalized form acute inflammation is present with the proliferation and clefting of the gingival margin. This paradigm started with the classical ‘experimental gingivitis’ studies published by Harald Löe and his colleagues from 1965 to 1968 26-29. So, to overcome these difficulties, a new term “Chronic periodontitis” was given to categorize these patients. Outside Assignments. A new classification scheme for periodontal and peri-implant diseases and conditions–Introduction and key changes from the 1999 classification. This classification was quite different from earlier classifications as it addressed a wide variety of periodontal diseases and conditions. deposits were present on the teeth, deep pockets were seen in later stages with the loosening of teeth and eventually leading to tooth loss. Have students create a chart differentiating the classifications of periodontal disease. It is important to discuss this classification as the American Academy of Periodontology (AAP) in 1986 adopted a new classification that incorporated these groups. Incisors and molars are more severely affected as compared to rest of the dentition. Development of a Classification System Disease names which last with “itis” have an inflammatory etiology, for example, periodontitis. Aggressive periodontitis

The authors were charged with updating the 1999 classification of periodontal diseases and conditions 1 and developing a similar scheme for peri‐implant diseases and conditions. Periodontitis as a manifestation of systemic disease. 1). This classification grouped different forms of plaque-induced periodontal diseases.4 The revised classification includes seven different types of plaque-induced periodontal diseases: • Gingivitis • Chronic periodontitis • Aggressive periodontitis (1958) 17. Caton JG, Armitage G, Berglundh T, et al. (1999). An organizing committee from the AAP and EFP commissioned 19 review papers and four consensus reports covering relevant areas in periodontology and implant dentistry. The steering committee invited The 1999 classification system has been approved by the AAP, is now official terminology for that organization, and will be used in accredited graduate periodontal programs and board examinations. Our basic understanding regarding periodontal diseases and the concepts in the etiopathogenesis of periodontal diseases have evolved and substantially changed during the past centuries. Neutrophil and monocyte function defects are not usually present. This classification system of periodontal disease was developed during the International Workshop for a Classification of Periodontal Diseases and Conditions (IWCP) October 30th – November 2nd 1999. Although these cases are common at the age 35 years or more, but this condition can be seen in adolescents and even in the primary dentition of children. Open in figure viewer PowerPoint. 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. Armitage GC. Most of the patients respond appropriately to the treatment, but a small number of patients are refractory to treatment. KEY WORDS Periodontal diseases/classification; gingival diseases/ classification. classification criteria. Periodontitis simplex was secondary to gingivitis and characterized by bone loss, pockets, abscess formation and calculus deposits. Periods of disease progression and regression may occur in a random manner in this condition. For the ease of understanding, let us divide the classification systems proposed on the basis of dominant paradigms. Proceedings of the World Workshop in Clinical Periodontics. ……………..Contents available in the book……….Contents available in the book……….Contents available in the book……….Contents available in the book….. The attachment loss in the absence of periodontitis (such as toothbrush trauma) cannot be considered as periodontitis. Although it is a fact that this condition is commonly found in people under 35 years of age, but it may also affect older patients. This practice has been advocated for reasons that vary from symbolic ritual to preventive health measure. Classification also helps us to formulate the treatment plan, predict the outcome of treatment as well as to educate the patient about the disease. This condition shared many features with the Calcic inflammation of the peridental membrane (presently called as periodontal ligament) except that the calculus deposition was less and there was an irregular pattern of alveolar bone destruction. In the 1999 International Workshop for a Classification of Periodontal Diseases and Conditions, the authors of the Consensus Report on Chronic Periodontitis stated that chronic periodontitis is “An infectious disease resulting in inflammation within the supporting tissues of the teeth, progressive attachment, and bone loss. Based on the classical pathology paradigm, many classifications were given during this time period. In the generalized form acute inflammation is present with the proliferation and clefting of the gingival margin. The initial classification systems were based on the, Diseases are classified to simplify our understanding regarding different diseases in a particular medical or dental field. This new classi- fication has numerous subcategories; only the major categories will be discussed here. New research findings dictate regular revisions of classification systems for the periodontal diseases (American Academy of Periodontology [AAP], 1989; AAP, 1999). The Parameters of Care 4 approved by the AAP have adopted the new classification and future publications will use it as their standard. The severity of the disease is categorized as Slight (1-2mm of loss of attachment), Moderate (3-4mm of loss of attachment), or Severe (≥5mm of loss of attachment). 1989 AAP classification of periodontal diseases was based on the following factors. One more point to be mentioned here is regarding the recession. The 1999 classification system has been approved by the AAP, is now official terminology for that organization, and will be used in accredited graduate periodontal programs and board examinations. A more convenient and simplified summary is: Figure 2. Let’s embrace the “change!” The American Academy of Periodontology Classifications are created to … If the AAP has not re-classified periodontitis since 1999, there is a good chance it will be at least ten or twenty years before we have new guidelines.
