Oral Surgeons License Suspended for Five Years After Patients Contract Bacterial Infection of the Heart

by

An oral surgeon in New Jersey has agreed to a five year suspension of his license after 15 patients contracted the bacterial heart infection endocarditis at his office. The oral surgeon also agreed to pay $243,500 in penalties and $50,000 in costs totaling $293,500, to resolve the State of New Jersey’s allegations that he exposed his patients to the risk of contracting endocarditis due to his failure to follow proper infection control procedures at this office. Twelve of the fifteen patients who contracted endocarditis required subsequent surgery and one died as a result of the bacterial heart infection. The investigation into the oral surgeon’s practice began after a 25 year old man was diagnosed with endocarditis about five weeks after having two of his wisdom teeth extracted in June 2014. Specifically the New Jersey Department of Health officials and Enforcement … Read more

Dental Plaque May Trigger Blood Clots

by

Oral bacteria that escape into the bloodstream are able to cause blood clots and trigger life-threatening endocarditis. Streptococcus gordonii is a normal inhabitant of the mouth and contributes to plaque that forms on the surface of teeth. However, if these bacteria enter into the blood stream through bleeding gums they can start to wreak havoc by masquerading as human proteins. Researchers from the University of Bristol and the Royal College of Surgeons in Ireland (RCSI) have discovered that S. gordonii is able to produce a molecule on its surface that lets it mimic the human protein fibrinogen — a blood-clotting factor. This activates the platelets which then clump inside blood vessels. These unwanted blood clots will then encase the bacteria, protecting them from the immune system and from antibiotics that might be used to treat infection. Platelet clumping can lead to … Read more
