Abstract
Objective: To inform about the importance of dental work in the prevention and treatment of Helicobacter pylori infection. Bibliographic review: Helicobacter pylori are a Gram-negative bacterium that infects humans and has a carcinogenic potential. The main routes of transmission of this pathogen are through contaminated water or food or oral-oral. Normally, this microorganism settles in the stomach, however, the oral cavity can temporarily shelter it in niches in the dental and gingival biofilm, saliva, tongue, grooves and even in conditions related to inflammatory processes such as periodontitis and aphthous ulcers. Thus, H. pylori can be transmitted from one individual to another through oral-oral means or even cause reinfection in an already infected patient. Therefore, specialized control of dental biofilm is an important factor in the prevention and treatment of Helicobacter pylori infection. Final considerations: The treatment of Helicobacter pylori infection should be done in an interdisciplinary way between the doctor and the dental surgeon in order to prevent the transmission of the pathogen by oral-oral route and the reinfection of the patient.
