Answer: A - Aggressive perodontitis has two forms: generalized and localized. The generalized form is aggressive, with episodic and severe attachment separation and there is obliteration of tissue around the majority of teeth. Eikenella corrodens and Prevotella intermedia causes the majority of damage. The localized form has severe attachment separation that is confined to the incisors and first molars. There is a genetic predisposition suspected or a chemotactic defect of the neutrophils. Actinobacillus Actinomycetemcomitans and Capnocytophaga varieties cause the majority of damage.
