Infective endocarditis and the heavily restored dentition: are clinicians becoming more complacent regarding...

The use of antibiotic prophylaxis to reduce the risk of infective endocarditis (IE) in susceptible individuals is a topic which has historically prompted many controversial debates. In the past, dentists have been understandably unwilling to prescribe antibiotic prophylaxis for fear of deviating from the National Institute for Health and Care Excellence (NICE) guidelines. However, in 2016, NICE altered the wording of these guidelines. The subtle change in wording implied that the clinician could use their clinical judgement, alongside advice from cardiologists, to deem their patient high-risk enough to prescribe antibiotics. In this article we discuss the implications of the NICE guidelines, and present the case of a patient who historically received antibiotic prophylaxis due to a history of rheumatic fever. Following the old NICE guidelines of 2008 he no longer received this prescription. As a consequence, he went on to suffer from IE from an unexpected cause due to ineffective preventative advice.
