Analysing Subgingival Plaque with regard to H.pylori at Chronic and Aggressive Periodontitis Patients

Background: Helicobacter pylori (H. Pylori) is a Gram (-),microaerophilic bacteria and the etiological factor of chronic activegastritis and peptic ulcer. Some studies indicated that thisbacterium found at oral cavity which is a potential reservoir forstomach. Several studies showed that H. pylori may found insaliva and subgingival plaque of chronic periodontitis patients.However, there is no data related to aggressive periodontitispatients. In this study, we aimed to determine the prevalence of H.pylori in subgingival plaque samples of chronic, aggressiveperiodontitis and gingivitis patients and to increase the awarenessof the patients for gastric problems.Materials and Methods: This study included 155 patients (61with gingivitis, 60 with chronic periodontitis, and 34 withaggressive periodontitis) who did not have gastric diseasesymptom and did not use antibiotics in the last 3 months. Thesubgingival 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 ofmicrobiological analysis. However, a high occurrence of A.actinomycetemcomitans (97.1%) and P. gingivalis (100%) wasobserved in the aggressive periodontitis group. However, A.actinomycetemcomitans and P. gingivalis were found in 30% and21.7% of patients, respectively, with chronic periodontitis. A.actinomycetemcomitans and P. gingivalis were found in 24.6% ofpatients in the gingivitis group.
