Background: Helicobacter pylori (H. Pylori) is a Gram (-),
microaerophilic bacteria and the etiological factor of chronic active
gastritis and peptic ulcer. Some studies indicated that this
bacterium found at oral cavity which is a potential reservoir for
stomach. Several studies showed that H. pylori may found in
saliva and subgingival plaque of chronic periodontitis patients.
However, there is no data related to aggressive periodontitis
patients. In this study, we aimed to determine the prevalence of H.
pylori in subgingival plaque samples of chronic, aggressive
periodontitis and gingivitis patients and to increase the awareness
of the patients for gastric problems.
Materials and Methods: This study included 155 patients (61
with gingivitis, 60 with chronic periodontitis, and 34 with
aggressive periodontitis) who did not have gastric disease
symptom and did not use antibiotics in the last 3 months. The
subgingival plaque samples were taken using sterile paper points.
The existence of H. pylori, A. actinomycetemcomitans, and P.
gingivalis was detected by RT-PCR.
Results: H. pylori was not detected in any groups at the end of
microbiological analysis. However, a high occurrence of A.
actinomycetemcomitans (97.1%) and P. gingivalis (100%) was
observed in the aggressive periodontitis group. However, A.
actinomycetemcomitans and P. gingivalis were found in 30% and
21.7% of patients, respectively, with chronic periodontitis. A.
actinomycetemcomitans and P. gingivalis were found in 24.6% of
patients in the gingivitis group.
