Objective. The aim of this study was to investigate the presence of He
licobacter pylori in both dental plaque and gastric mucus. Study desig
n. Dental scaling hand instruments were used to collect supragingival
and subgingival dental plaque from 81 dentate participants. Denture pl
aque was obtained from the fitting surfaces of dentures from 41 edentu
lous patients. Gastric mucus from gastric mucosa of antrum and body of
stomach were collected from all 122 participants (92% white) with a s
oft gastroscopic brush. These samples were dispersed in modified urea
broth and normal saline solution before being inoculated onto selectiv
e Skirrow's agar and incubated in a microaerophilic atmosphere for cul
turing H. pylori Results. Dental plaque from all dentate participants
was negative for H. pylori culture. Only one 80-year-old edentulous pa
tient had positive H. pylori culture in both gastric mucus and denture
plaque. Conclusions. Although dental plaque has a mixed flora that ma
y act as a reservoir for gastric reinfection, dental plaque could not
be implicated as the major reservoir of H. pylori for gastric reinfect
ion.
