Guidelines for antibiotic prophylaxis — In the past, American Heart Association guidelines recommended that most patients with a heart murmur receive antibiotics prior to almost any dental procedures, even minor ones. However, these guidelines have changed considerably over time as more information has become available about the actual risk of dental procedures for patients with heart conditions. Review of studies performed between 1950 and 2006, which included thousands of patients, has shown that there was no benefit of using preventive antibiotics, except in the highest risk patients [1].
