The entity of aggressive periodontitis is characterized by:

• The rapid loss of attachment and tooth-supporting bone,

• The subject is otherwise healthy (i.e., not suffering from any systemic disease or condition that could be responsible for the present periodontitis),

• The presence of familiar aggregation.

• Malocclusion and halitosis

Generalized aggressive periodontitis (GAP) is the subgroup of:

• Chronic periodontitis,

• Aggressive periodontitis.

• Pericoronitis.

• Gingivitis.

Localized aggressive periodontitis (LAP) is the subgroup of:

• Aggressive periodontitis,

• Necrotizing ulcerative periodontitis.

• Chronic periodontitis,

• Pericoronitis.

Aggressive periodontitis is subclassified into:

• Localized aggressive periodontitis (LAP) and localized juvenile periodontitis (LJP)

• Generalized aggressive periodontitis (GAP) and Localized aggressive periodontitis (LAP)

• Slowly progressive periodontitis and rapid progressive periodontitis.

• Generalized chronic periodontitis and Localized chronic periodontitis.

The diagnosis of the subcategory of aggressive periodontitis is not based on:

• Clinical data,

• Radiographic data,

• Historic data,

• Patient statements

Aggressive periodontitis generally affects systemically healthy individuals less than:

• 30 years old or older,

• 20 years old or older,

• 35 years old or older.

• 15 years old or older.

Aggressive periodontitis is universally distinguished from chronic periodontitis not by:

• The age of onset, the rapid rate of progression.

• Nature and composition of microflora, alteration in the host’s immune response.

• Familial aggregation of the diseased individuals.

• The degree of gingival recession

Localized aggressive periodontitis usually characterized as having localized first molar/ incisor presentation with interproximal attachment loss on at least two permanent teeth, one of which is a first molar, and involving no more than:

• One tooth other than first molars and incisors.

• Two teeth other than first molars and incisors.

• Tree teeth other than first molars and incisors.

• Four teeth other than first molars and incisors.

The major organism seen in aggressive periodontitis is:

• A. actinomycetemcomitans

• P. gingivalis.

• T. forsythia.

• F. nucleatum and P. gingivalis.

In aggressive periodontitis, arc-shaped bone loss extending from the distal surface of the second premolar to the mesial surface of:

• The second molar,

• The third molar,

• The third molar.

• The first premolar.
