Abstract
Aims: To assess the comparative presence of Helicobacter pylori (H. pylori) in saliva of
smokers and nonsmokers with chronic periodontitis.
Study Design: Male individuals diagnosed with chronic periodontitis with and without smoking habits were enrolled in the study. The unstimulated whole saliva was subjected
to H. pylori DNA detection using real time PCR. The percent presence of H. pylori DNA
among the groups, were statistically compared.
Place and Duration of the Study: Department of Biochemistry and Department of
Dentistry, Grant Medical College and Sir JJ group of Hospitals, Mumbai and
Department of Microbiology, Sinhgad Dental College, Pune, between January 2010 and
June 2010.
Materials and Methods: A total of 48 males with severe chronic periodontitis
(CAL≥5mm) were divided into two groups, Group I (n=30, mean age=44.2±5.88 yrs)
with smoking habit, Group II (n=18, mean age 41.72±4.36yrs) without any smoking
habit. Nonsmokers with slight chronic periodontitis (CAL<3mm) were enrolled as
controls, Group III (n=16, mean age 39.64±5.04 yrs). Periodontal status was evaluated
by measuring gingival index (GI), plaque index (PI), probing depth (PD) and clinical
attachment loss (CAL). Salivary samples were subjected to real time PCR for detection
of H. pylori DNA.
Result: Periodontal parameters were significantly different between Group I and II
compared to Group III (P=.001). Overall, H. pylori was not detected in Group III (100%
negative), whereas 5.5% of Group II and 13.3% in Group I patients showed presence
of H. pylori. Chi-square test showed a significant difference (P=.003) between Group I
and Group III however it was seen that there was an insignificant difference between
Group I and Group II (P=.312) and between Group II and Group III (P=.186).
Conclusion: The smokers with chronic periodontitis may be at a relatively higher risk
of H. pylori presence in the oral cavity, than non smokers. The study needs validation
on a larger sample size.
