Abstract
BACKGROUND Eradication of oral Helicobacter pylori (H. pylori) not only reduces the infection rate from the transmission route but also improves the success rate of intragastric eradication. MAXPOWER Biological Bacteriostatic Liquid, developed in our previous work, is a composite biological preparation with strong antibacterial ability and unique antibacterial mechanism. The present study evaluated the efficacy of the MAXPOWER biocontrol solution on H. pylori and its success rate in eradicating oral H. pylori in clinical patients. METHODS Live-dead cell staining and hemolysis test were used to evaluate the cellular safety of MAXPOWER biocontrol solution; plate spreading, live-dead bacterial staining, and scanning electron microscopy methods were used to evaluate its antimicrobial effect against H. pylori. Transcriptomics was used to analyze the changes in H. pylori genes before and after treatment. After seven days of gavage treatment, H&E staining and mice feces were collected for 16SrDNA sequencing to evaluate the animals' safety. Oral H. pylori-positive patients were randomized to be given a placebo and MAXPOWER Bio-Bacteriostatic Liquid gargle for seven days to evaluate the effect on oral H. pylori eradication. RESULTS In vitro tests demonstrated that this product has excellent biocompatibility and hemocompatibility and can effectively eradicate oral H. pylori. In vivo tests further showed that it has good biosafety and virtually no adverse effect on intestinal microflora. Transcriptomics analysis revealed that it kills H. pylori cells mainly by disrupting their cell membranes and metabolism. Additionally, the results of randomized controlled trials on humans disclosed that the oral H. pylori eradication rates achieved by MAXPOWER Biological Antibacterial Liquid were 71.4% and 78.9% according to the intention-to-treat and the per-protocol analysis, respectively. CONCLUSION MAXPOWER Biological Antibacterial Liquid is both safe and efficacious in the eradication of oral H. pylori. TRIAL REGISTRATION This study was retrospectively registered in the ClinicalTrials.gov Trial Registry on 21/09/2023 (NCT06045832).

Abstract
Helicobacter pylori (H. pylori) is transmitted primarily through the oral–oral route and fecal–oral route. The oral cavity had therefore been hypothesized as an extragastric reservoir of H. pylori, owing to the presence of H. pylori DNA and particular antigens in distinct niches of the oral cavity. This bacterium in the oral cavity may contribute to the progression of periodontitis and is associated with a variety of oral diseases, gastric eradication failure, and reinfection. However, the conditions in the oral cavity do not appear to be ideal for H. pylori survival, and little is known about its biological function in the oral cavity. It is critical to clarify the survival strategies of H. pylori to better comprehend the role and function of this bacterium in the oral cavity. In this review, we attempt to analyze the evidence indicating the existence of living oral H. pylori, as well as potential survival strategies, including the formation of a favorable microenvironment, the interaction between H. pylori and oral microorganisms, and the transition to a non-growing state. Further research on oral H. pylori is necessary to develop improved therapies for the prevention and treatment of H. pylori infection.

Abstract
Many studies have shown a connection between poor oral health and a number of systemic diseases. Recent studies have demonstrated an association between poor oral health and the oral microbiota to carcinogenesis. This review article will focus on studies that link oral dysbiosis, periodontal disease, and specific oral microorganisms to gastrointestinal malignancies. These studies provide some insight and understanding of the role of the oral microbiome in carcinogenesis. Understanding how the oral microbiota is related to carcinogenesis and gastrointestinal malignancies could lead to identifying biomarkers and provides future treatment modalities. More research in this area would be beneficial to the diagnosis and treatment of patients with gastrointestinal malignancies.

Abstract
Objectives The efficacy of conventional systemic antibiotic therapy for eradication of Helicobacter pylori has been seriously challenged by antibiotic resistance. Identification of alternative therapeutic strategies might help to overcome this limitation. The aim of this study was to update previous meta-analyses that investigated the effect of periodontal treatment on gastric H. pylori eradication. Methods A systematic electronic search of the literature was conducted to identify all published clinical trials that compared the effect of adjunct periodontal treatment on conventional systemic H. pylori eradication therapy. Results The updated analysis (consisting of 541 participants representing six studies) demonstrated that, compared with conventional systemic eradication therapy alone, the addition of periodontal treatment resulted in improvements in gastric H. pylori eradication rates with OR 4.11 (P = 0.01). Moreover, not to lose any data, the previously presented Chinese results that could not be assessed by any available mechanism deduced from previously published meta-analysis and with other records were re-analysed. Similarly, the second meta-analysis adding up to a final cluster of 10 studies (909 participants) gives further credence to periodontal treatment as a useful concomitant therapy in the H. pylori eradication therapy (odds ratio [OR] = 2.65; P = 0.0002). Finally, the meta-analysis of four trials consisting of 177 cases and 161 controls showed that periodontal treatment also improved non-recurrence rates of gastric H. pylori infection, with an OR of 5.36 (P-value = 0.0002). Conclusion Although the inclusion of five additional clinical trials in this updated meta-analysis has not changed the result of the previous review, the current meta-analysis is superior for having removed one study involving the use of chlorhexidine, which did not meet appropriate criteria for inclusion. Our results strengthen the value of periodontal treatment as an adjunctive remedy. Consistency of these results suggests that the incorporation of professional periodontal treatment with systemic eradication therapy may be a wise strategy, enhancing the efficacy of H. pylori eradication therapy.

Int Dent J 2020; 70:227-236. [PMID: 31998967 DOI: 10.1111/idj.12542] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Revised: 10/26/2019] [Accepted: 11/02/2019] [Indexed: 12/25/2022] Open
Abstract
OBJECTIVES Inflammatory bowel disease (IBD) may be associated with oral diseases, but few relevant studies have been reported in China. This study aimed to compare the prevalence, severity and extent of dental caries and periodontal disease in Chinese IBD patients and healthy controls. MATERIALS AND METHODS In this cross-sectional study, questionnaires and oral examinations were completed for 389 IBD patients [265 with Crohn's disease (CD) and 124 with ulcerative colitis (UC)] and 265 healthy controls based on the established criteria of the World Health Organization. Tobit regression, multiple linear regression and logistic regression were performed to analyse the data. RESULTS After adjusting for confounders, the decayed, missing and filled surfaces indices were significantly increased in the CD and UC patients compared with those in the controls (P < 0.001). Patients with CD [odds ratio (OR) = 4.27, 95% confidence interval (95% CI): 2.63-6.95, P < 0.001] and UC (OR = 2.21, 95% CI: 1.24-3.94, P = 0.007) had significantly higher risks of dental caries than controls. Significantly higher percentages of sites with probing pocket depth ≥ 5 mm and clinical attachment loss ≥ 4 mm were observed in CD and UC patients compared with controls (P < 0.001). A fully adjusted model revealed that CD and UC were risk indicators for periodontitis (OR = 4.46, 95% CI: 2.50-7.95, P < 0.001; OR = 4.66, 95% CI: 2.49-8.71, P < 0.001, respectively). No significant differences in dental caries and periodontal disease were observed between the CD and UC patients. CONCLUSIONS Chinese IBD patients have a higher prevalence, severity and extent of dental caries and/or periodontal disease than controls, and require oral health education and multidisciplinary treatment.
