Abstract:
This cross-sectional study was carried out to identify
A. actinomycetemcomitans and P. intermedia in the
subgingival plaque of three ethnic groups (Malays,
Chinese and Indians) in a selected group of adult
Malaysians with advanced Chronic Periodontitis and
to correlate these findings with their periodontal status.
Thirty periodontally diseased adults were age, gender
and ethnically matched with 30 healthy individuals.
Clinical parameters were assessed for all. Subgingival
plaque samples were collected for identification of
A. actinomycetemcomitans and P. intermedia using
polymerase chain reaction. Prevalence for P. intermedia
(83.3%) was high and A. actinomycetemcomitans
(6.7%) low in the total subject population. P.
intermedia and A. actinomycetemcomitans were more
prevalent in diseased (86.7%, 10% respectively) than
in healthy (80%, 3.33% respectively) subjects. A.
actinomycetemcomitans was detected in 15% Indians,
5% Malays but none of the Chinese subjects whereas
P. intermedia was detected in 90% Malays, 85%
Indians and 75% Chinese subjects. No significant
association between presence of A. actinomycetemcomitans
and P. intermedia with race and
periodontal disease status was found. Only A.
actinomycetemcomitans had a significant association
with clinical attachment level (CAL) (p < 0.05). In
conclusion, in this small subject group, none of the
pathogens were associated with race and periodontal
disease status and only A. actinomycetemcomitans had
a significant association with CAL.
