Relationship between oral problems and Helicobacter pylori infection

In a cross-sectional analysis, the prevalence of Hp infection was strongly related with several social problems, including age, gender, BMI, smoking and regular drinking. In addition, oral problems, particularly dental calculus and loose tooth, were found to be associated with Hp infection, possibly due to the dental plaque. The study suggested that to prevent or eradicate Hp infection, we need to focus on oral hygiene and prevention of oral problems, especially dental calculus and loose tooth.
