Poor Oral Hygiene: A Hidden Risk Factor for Helicobacter pylori Infection.
Article in International dental journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHelicobacter pylori (H. pylori) initially enters the human body through the mouth. The correlation between oral health and H. pylori infection status remains a topic of debate in the scientific literature. To elucidate the relationships between H. pylori infection and oral hygiene status and habits, we performed a cross-sectional study among dyspeptic patients.
methodsData were collected from 362 subjects with dyspepsia symptoms who underwent the 13C-urea breath test (13C-UBT) and the H. pylori antigen test (HPS) to test for gastric and oral H. pylori infections between May and August 2023 at The Second Affiliated Hospital of Xi'an Jiaotong University. The participants completed questionnaires on sociodemographic characteristics, medical history, dyspepsia symptoms, oral hygiene status, and oral hygiene practices. In addition, the participants underwent oral exams involving the simplified oral hygiene index (OHI-S), the Debris index (DI-S), the simplified calculus index (CI-S), and the decayed, missing, and filled teeth (DMFT) score.
resultsOral H. pylori infection status was not associated with sex, body mass index (BMI), education, oral hygiene habits, place of residence, or income. Considering sex and BMI, being over 60 years of age significantly increased the risk of developing oral H. pylori infection (OR = 5.51, 95% CI: 1.56-19.46, P = .0081), whereas a lack of history of antibiotic use was identified as a protective factor (OR = 0.45, 95% CI: 0.26-0.77, P = .0036). Additionally, DMFT >4 (OR = 2.54, 95% CI: 1.15-5.61, P = .0210), 0.67 < OHI-S ≤ 1.33 (OR = 1.98, 95% CI: 1.09-3.59, P = .0246), and 0.33<DI≤0.67 (OR = 2.00, 95% CI: 1.11-3.62, P = .0215) were identified as independent risk factors for oral H. pylori infection.
conclusionThe results of our research indicate a relationship between oral health and oral H. pylori infection, suggesting that poor oral hygiene may be associated with an increased risk of oral H. pylori colonization.
