prevalence of actinobacillus actinomycetemcomitans in a Scottish chronic periodontitis patients

ABSTRACT

The prevalence of A.actinomycetemcomitans in 98 Scottish patients with chronic periodontitis [302 subgingival sites] and 55 health control subjects was investigated. The organism was isolated from 39% of patients and from 27% of the total samples collected. However, only one 2% of the 55 control subjects possessed A.actinomycetemcomitans. A.actinomycetemcomitans was isolated overall from more sites in male patients [60%] compared to female patients [40%]. In general there were no clear differences between the prevalence of A.actinomycetemcomitans in the six different segments sampled in the 98 patients
