Objective:

To determine the prevalence of helicobacter pylori in dental biofilm in patients with chronic gastritis in the gastroenterology service of the María Auxiliadora Hospital.

Methods:

A cross-sectional descriptive observational study was carried out, working with a population of patients treated in 1 calendar year, of which only 100 patients met the inclusion and exclusion criteria. A collection was made for the variables age, sex, helicobacter pylori in dental biofilm and helicobacter pylori in gastric mucosa biopsy. The relative frequency of Helicobacter Pylori in dental biofilm in patients with chronic gastritis was calculated and an exploratory chi2 test was performed for helicobacter in dental biofilm and helicobacter in gastric mucosa biopsy.

Results:

A 66% prevalence of helicobacter pylori in dental biofilm was detected in patients with chronic gastritis, in turn 48% of the total in this group presented positive helicobacter pylori in gastric mucosa biopsy. Of the patients positive for helicobacter pylori in gastric mucosa, 83.33% presented positivity in dental biofilm. An association was found for the variables helicobacter pylori in dental biofilm and helicobacter pylori in gastric mucosa biopsy with a p value = 0.002.

Conclusion:

A high prevalence of helicobacter pylori was found in dental biofilm of patients with chronic gastritis and an association between dental biofilm and gastric mucosa biopsy for helicobacter pylori.
