What was done
This narrative review evaluated the literature regarding the dissemination of oral bacteria and endotoxins into the bloodstream from gingivitis and periodontitis during dental procedures and daily activities such as tooth brushing. It examined the potential pathological consequences across major organ systems and summarized suggested preventive and treatment measures.
What was found
The abstract reports no quantitative data or specific numerical effect sizes. It notes qualitatively that oral bacteria and endotoxins enter the systemic circulation via gingival injuries, potentially causing secondary bacterial infections or immunological reactions in distant organs (including sepsis, infective endocarditis, lung infections, and liver disease), particularly in immunocompromised individuals or those with underlying conditions. The authors identify plaque control as the primary preventive approach.
Why it matters
The review highlights the biological plausibility linking routine oral inflammation and transient bacteremia to systemic organ complications, emphasizing the role of basic oral hygiene and plaque removal in systemic disease prevention.
Limits
This is an unsystematic narrative review with no defined inclusion criteria, primary experimental data, or statistical pooling. The abstract does not quantify absolute risks, infection rates, or the magnitude of risk reduction conferred by specific oral hygiene interventions.
