Recommendations for antibiotic prophylaxis prior to certain dental procedures have existed historically for two groups of patients:

• Those with heart conditions that may predispose them to infective endocarditis; and
• Those who have a prosthetic joint(s) and may be at risk for developing hematogenous infections at the site of the prosthetic.

However, compared with prior recommendation statements, there are currently relatively few patient subpopulations for whom antibiotic prophylaxis may be indicated prior to certain dental procedures.

The guidelines say patients who have taken prophylactic antibiotics routinely in the past but no longer need them include people with:

1. mitral valve prolapse
2. Rheumatic heart disease
3. Bicuspid valve disease
4. Calcified aortic stenosis
5. Congenital heart conditions such as ventricular septal defect, atrial septal defect and hypertrophic cardiomyopathy

• All patients during the first two years after joint replacement (or as directed by their orthopedic surgeon)
• immunocompromised/immunosuppressed patients ( inflammatory arthropathies for example rheumatoid arthritis, systemic lupus erythematosus, druge induced immunosuppression, radiation indiced immunosuppression
• Patients with co-morbidities such as (previous prosthetic join infections, malnourishment, hemophilia, HIV infection, insulin dependent (type 1) diabetes, malignancy)

For further questions contact your surgeon , doctor , and dentist.
