Answer.

Etiology of Local Juvenile Periodontitis

Local Juvenile Periodontitis Microbiological

Presence of Aggregatibacter actinomycetemcomitans is a key factor which present in high numbers. Virulence factors produced by Aggregatibacter actinomycetemcomitans such as leucotoxin, lipopolysaccharide, proteases, collagenases, surface associated material affect immune response and lead to connective tissue destruction and bone resorption.

Local Juvenile Periodontitis Immunological

• Defective chemotaxis due to functional defect in polymor-phoneutrophils.
• Presence of hyper-responsive monocytes which increases prostaglandin IL-1α and IL-1β production which causes bone resorption.

Local Juvenile Periodontitis Genetic

• Familial aggregation is seen.
• As there is presence of specific gene which causes neutrophil abnormalities.
• Transmission through autosomal dominant mode of inheritance.
