Abstract:
Objective: To determine the distribution of Actinobacillus actinomycetemcomitans (Aa) in subgingival plaques in the patients with chronic periodontitis(CP). Methods: Samples of subgingival plaque were detected for Aa distribution by oligonucleotide probe from 60 sites of CP patients and 10 healthy sites of healthy people.Each sample was obtained from each site of each people. Results: Aa was detected in 19 out of 60 diseased sites(31.67%); Aa wasn't detected in healthy sites.The age(28.68±7.33) of Aa-positive patients was younger than that (44.48±12.48) of Aa-negative patients(P<0.05).Conclusion: Aa is possibly to cause chronic periodontal infection in younger people.
