Conditions

Periodontal Disease

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.
