Prophylactic antibiotic coverage in patients with total arthroplasty: current practice.

Area of Science:

• Orthopedics
• Dentistry
• Infectious Diseases

Background:

• The necessity of prophylactic antibiotics before dental treatment to prevent late prosthetic joint infections remains unproven.
• While most orthopedic surgeons surveyed perceived no link between dental bacteremias and joint infections, they often still recommended prophylaxis.
• Existing literature shows few late prosthetic joint infections attributable to dental-induced transient bacteremias.

Purpose of the Study:

• To evaluate the established need for antibiotic prophylaxis before dental procedures to prevent prosthetic joint infections.
• To analyze current recommendations and literature regarding dental bacteremias and prosthetic joint infections.
• To provide guidance for dental practitioners treating patients with arthroplasty.

Main Methods:

• Survey of orthopedic surgeons regarding their views on antibiotic prophylaxis for dental procedures.
• Review of current scientific literature on prosthetic joint infections and dental bacteremias.
• Analysis of antibiotic preferences and their suitability for oral bacteria.

Main Results:

• Most orthopedic surgeons believed no relationship exists between dental bacteremias and prosthetic joint infections.
• A majority of surveyed surgeons recommended antibiotic prophylaxis despite this perceived lack of relationship.
• Cephalosporins were the preferred prophylactic antibiotic, though penicillin may be more appropriate for oral streptococci.

Conclusions:

• The relationship between dental-induced bacteremias and prosthetic joint infections requires further research.
• Current evidence does not definitively establish the need for routine antibiotic prophylaxis for all dental procedures in patients with joint replacements.
• Dental practitioners should consult orthopedic surgeons for prophylaxis recommendations, and a joint committee should evaluate data to form unified guidelines.
