Principle I: Procedure Should Have Significant Risk of Infection

For prophylactic antibiotics to reduce the incidence of infection, the surgical procedure must have a high enough incidence of infection to be reduced with antibiotic therapy. Clean sun.cry done with strict adherence to . basic surgical principles usually has an incidence of infection of about 3%. Infection rates of 10% or more are usually considered unacceptable, and the use of prophylactic antibiotics must be strongly considered. For the dentist doing routine office surgery, this means that most office procedures performed on healthy patients do not require prophylactic antibiotics. The incidence of infection after tooth extraction, frenectomy, biopsy, minor alveoloplasty, and torus reduction is extremely low; therefore antibiotics
would provide no benefit. • liowever, several surgical factors may influence the dentist  o consider strongly the use of antibiotic prophylaxis
(Box 15-9):  The first and most obvious factor that may lead0to infection is a bacterial inoculum of sufficient size. The usual surgical procedure performed in the mouth rarely involves sufficient bacterial inoculation to cause infection. The second factor is surgical procedures that are rather
extensive ami require prolonged surgery. The incidence of infection increases both with the extent of surgery and with longer surgical procedures. A third factor that may suggest the use of antibiotics is the insertion or presenceof a foreign body, most commonly a dental implant.  Most data seem to suggest that the use of antibiotics may decrease the incidence of infection when foreign bodies,  such as dental implants, are inserted into the jaws. The final and most important factor for most dentists
in determining which patients should receive prophylactic antibiotics is whether the patient has depressed host defenses. Patients who have a compromised ability to defend themselves against infection should probably receive prophylactic antibiotics because they are likely to have a higher incidence of more severe infection. All patients receivingcancer chemotherapy or immun suppressives  hould receive prophylactic antibiotics, even
