Abstract
INTRODUCTION: This study aimed to analyze the existing evidence on the association between dental diseases and stroke. Various pathogenic mechanisms, including bacteraemia and systemic inflammation, were investigated to explore their impact on stroke occurrence and severity. METHODS: A comprehensive literature search was conducted through the online databases PubMed, Google Scholar, Web of Science, and Scopus. The initial screening process resulted in a total of 138 articles being gathered. Upon subsequent refinement, 52 articles were discarded due to duplication or non-English language, leaving 86 articles for further assessment. RESULTS: Oral bacteria can travel to the brain's blood vessels and cause bacteraemia, leading to local inflammation and the release of toxins. This process can result in the blockage or rupture of blood vessels, leading to stroke. Oral infections consistently trigger immune responses and systemic inflammation, with inflammation-related proteins playing a crucial role in stroke development. Notably, periodontal treatment could reduce the risk of stroke. CONCLUSION: This review emphasizes the role of dental diseases in promoting stroke occurrence through various mechanisms. Dental diseases contribute to the development of stroke by facilitating bacteraemia and systemic inflammation. Furthermore, through effectively treating and preventing dental diseases, the risk of strokes can be significantly reduced.
