The term juvenile periodontitis is used to refer to periodontitis may be universally distinguished from the second group. Both prepubertal and pubertal chronic periodontitis by the age of onset, the rapid forms have been sub-classified into localized and rate of disease progression, the nature and generalized forms, depending on their distribution in composition of the associated sub gingival micro the mouth.6 This is an extremely rare form of flora, alterations in the host‟s immune response, and periodontal disease characterized by rapid a familial aggregation of diseased individuals.2 In periodontal destruction of the primary dentition.4 The addition, a strong racial influence is observed in the disease begins about the age of 4 years or before, during or immediately after eruption of the primary United States; the disease is more prevalent among 7 African Americans.3 Aggressive periodontitis teeth, but may affect the permanent dentition. Primary teeth are lost by the age of 5 or 6 years. The describes three of the diseases formerly classified as 1 permanent teeth then erupt normally but within few “early-onset periodontitis (EOP).” EOP can be years destructive periodontal disease affects all the practically divided into three groups; prepubertal teeth except the third molars. By the age of 15 most periodontitis, juvenile periodontitis and rapidly of the permanent teeth are lost.8 An extremely acute progressive periodontitis.4 Incidental attachment loss inflammation and proliferation of the gingival tissues, is a term used only in epidemiological studies to with rapid destruction of bone, are found.9 In many describe severe destructive lesions which affect instances there is a familial pattern to the disease, and isolated teeth without meeting the criteria for other most if not all cases are probably genetically 4 forms of EOP. This category includes attachment loss mediated. There is tendency for the disease to be adjacent to an impacted third molar.5 refractory to antibiotic therapy, frequent respiratory infections and destruction of the roots of teeth. 129 Dental Journal of Advance Studies Vol. 1 Issue III-2013 Normally children do not present with alveolar bone more sites.

He then termed the disease “deep permanent dentition of patients between the ages of cementopathia” and hypothesized that this was a 20 and 35 years. On present available evidence it is “disease of eruption” and that cementum initiated a difficult to justify the classification of this condition foreign body response.12 In 1938, Wannenmacher as a separate disease entity, as it could well represent described incisor–first molar involvement and called a rapidly progressive chronic periodontitis in a the disease “parodontitis marginalis progressiva.”1 susceptible individual. It is also important to Contrary to others at that time, Wannenmacher distinguish this condition from post-juvenile considered this disease an inflammatory process.9 periodontitis, and to remember that some conditions, Several explanations evolved for the etiology and such as Down's syndrome, have a high susceptibility pathogenesis of this type of disease.13 In 1940, to severe rapidly progressive periodontitis in the Thoma and Goldman used the term “paradontosis” to permanent dentition.4 refer to this disease; the initial abnormality was located in the alveolar bone rather than in the It may be associated with systemic disease and be cementum and consisted of vascular resorption and refractory to all forms of therapy. Most patients with halisteresis rather than “lacunar resorption”. In 1947, RP demonstrate abnormalities in peripheral blood Goldman described vascular resorption and neutrophil function that are manifested in an impaired halisteresis in a spider monkey as being due to a chemotactic ability.7 Distribution of lesions does not degenerative non-inflammatory disease of the show any definite pattern. It may be localized to few supporting structures. In 1942, Orban and Weinmann teeth or may be generalized.8 The features of RPP introduced the term “periodontosis” and, on the basis include an active phase of severe, rapid bone of one autopsy case studied in detail, described the destruction involving most of the teeth; spontaneous development of the disease. Most of the above or rapid slow-down of the process; proliferation and mentioned studies considered “periodontosis” a severe inflammatory response during active phase; degenerative disease caused by unknown systemic functional defects in neutrophils or monocytes in the factors. Glickman in 1952 believed that the majority of affected patients; the possibility of conditions described in these studies didn‟t represent previous juvenile periodontitis; and systemic a different type of periodontal disease, but rather disturbances that may include weight loss, mental extreme variants of destructive processes common to depression and general malaise. Treatment consisting all periodontal disease.9 Other investigators denied of root planing and antibiotic therapy is generally the existence of a degenerative type of periodontal effective.7 Patients with chronic periodontitis may disease and attributed the changes observed to trauma develop rapidly progressive periodontitis in one or from occlusion. Finally, in 1966, the World 130 Dental Journal of Advance Studies Vol. 1 Issue III-2013 Workshop in Periodontics concluded that the concept chemotaxis.
