<jats:title>ABSTRACT</jats:title><jats:p><jats:bold>Background. </jats:bold> <jats:italic>Helicobacter pylori</jats:italic> is a curved microaerophilic Gram‐negative bacterium considered as a risk factor for gastric cancer. The aim of this study was to find an association between burning sensations, acid taste, halitosis, and lingual hyperplasia with the effect of <jats:italic>H. pylori</jats:italic> on the mouth.</jats:p><jats:p><jats:bold>Materials and Methods. </jats:bold> A total of 124 subjects with different gastric diseases were studied: 46 patients with burning, halitosis and lingual dorsum hyperplasia and 78 patients with other diseases.</jats:p><jats:p><jats:bold>Results. </jats:bold> The detection of <jats:italic>H. pylori</jats:italic> in the oral cavity by histopathologic diagnosis and molecular biology was confirmed in 40/46 (87%) patients with burning, halitosis, and lingual hyperplasia, and in 2/78 (2.6%) subjects with other diseases. χ<jats:sup>2</jats:sup>: 91.26 (<jats:italic>p <</jats:italic> .001) Mantel–Haenszel.</jats:p><jats:p><jats:bold>Conclusion. </jats:bold> This trial showed an association between <jats:italic>H. pylori</jats:italic> and burning, halitosis, and lingual hyperplasia, and further considered this bacterium a risk factor for gastric infection.</jats:p>
