Abstract：
:Current paper aims to hypothesize that, oral surgical interventions such as tooth extractions, endosseous implant placement, subgingival curettage, etc. might result in widespread of fungal species via blood stream and can cause fungal contaminations of the cardiac valves. We hereby suggest that, an additional fungal endocarditis risk assessment and prevention protocol should be created for patients with a possible risk of endocarditis development.
