Brief Title  ICMJE Polymorphonuclear Cells' Sensitivity to Aggregatibacter Actinomycetemcomitans Bacteria in Patients With Aggressive Periodontitis
Official Title  ICMJE Not Provided
Brief Summary

aggressive periodontitis is an inflammatory disease which damage the teeth supporting structures mostly in young patients. and has genetic basis.

a specific bacteria: Aggregatibacter actinomycetemcomitans (Aa) is associated with this disease, and found to damage leukocytes by using a specific leukotoxin.

in the research the investigators are aiming to find molecular and immunological basis to aggressive periodontitis.
