Antibiotic Prophylaxis for Dental Patients with
Total Joint Replacements
An expert panel of dentists, orthopaedic surgeons and infectious disease
specialists, convened by the American Dental Association (ADA) and the American
Academy of Orthopaedic Surgeons (AAOS) performed a thorough review of all
available data to determine the need for antibiotic prophylaxis to prevent
hematogenous prosthetic joint infections in dental patients who have undergone
total joint arthroplasties. The result is this report, which has been adopted by
both organizations as an advisory statement. The panel's conclusion: Antibiotic
prophylaxis is not indicated for dental patients with pins, plates and screws,
nor is it routinely indicated for most dental patients with total joint
replacements. However, it is advisable to consider premedication in a small
number of patients (Table 1) who may be at potential increased risk of
hematogenous total joint infection.
Approximately 450,000 total joint arthroplasties are performed annually in the
United States. Deep infections of these total joint replacements usually result
in failure of the initial operation and the need for extensive revision. Due to
the use of perioperative antibiotic prophylaxis and other technical advances,
deep infection occurring in the immediate postoperative period resulting from
intraoperative contamination has been markedly reduced in the past 20 years.
Patients who are about to have a total joint arthroplasty should be in good
dental health prior to surgery and should be encouraged to seek professional
dental care if necessary. Patients who already have had a total joint
arthroplasty should perform effective daily oral hygiene procedures to remove
plaque (e.g. manual or powered toothbrushes, interdental cleaners, oral
irrigators) to establish and maintain good oral health. The risk of bacteremia
is far more substantial in a mouth with ongoing inflammation than in one that is
healthy and employing these home-oral hygiene devices.1
Bacteremias can cause hematogenous seeding of total joint implants, both in the
early postoperative period and for many years following implantation.2 It
appears that the most critical period is up to two years after joint placement.3
In addition, bacteremias may occur in the course of normal daily life4-6 and
concurrently with dental and medical procedures.6 It is likely that many more
oral bacteremias are spontaneously induced by daily events than are dental
treatment-induced.6 Presently, no scientific evidence supports the position that
antibiotic prophylaxis to prevent hematogenous infections is required prior to
dental treatment in patients with total joint prostheses.1 The risk/benefit7,8
and cost/effectiveness7,9 ratios fail to justify the administration of routine
antibiotic prophylaxis. The analogy of late prosthetic joint infections with
infective endocarditis is invalid as the anatomy, blood supply, microorganisms
and mechanisms of infection are all different.10
It is likely that bacteremias associated with acute infection in the oral
cavity,11,12 skin, respiratory, gastrointestinal and urogenital systems and/or
other sites can and do cause late implant infection.12 Any patient with a total
joint prosthesis with acute orofacial infection should be vigorously treated as
any other patient with elimination of the source of the infection (incision and
drainage, endodontics, extraction) and appropriate therapeutic antibiotics when
indicated.1,12 Practitioners should maintain a high index of suspicion for any
unusual signs and symptoms (e.g. fever, swelling, pain, joint warm to touch) in
patients with total joint prostheses.
Antibiotic prophylaxis is not indicated for dental patients with pins, plates
and screws, nor is it routinely indicated for most dental patients with total
joint replacements. This position agrees with that taken by the Council on
Dental Therapeutics,13 the American Academy of Oral Medicine,14 and is similar
to that taken by the British Society for Antimicrobial Chemotherapy.15 There is
limited evidence that some immunocompromised patients with total joint
replacements (Table 1) may be at higher risk for hematogenous infections.13,
16-22 Antibiotic prophylaxis for such patients undergoing dental procedures with
a higher bacteremic risk (as defined in Table 2), should be considered using an
empirical regimen (Table 3). In addition, antibiotic prophylaxis may be
considered when the higher risk dental procedures (as defined in Table 2) are
performed on dental patients within two years post implant surgery,3 on those
who have had previous prosthetic joint infections, and on those with some other
conditions (Table 1).
Occasionally, a patient with a total joint prosthesis may present to the dentist
with a recommendation from his/her physician that is not consistent with these
guidelines. This could be due to lack of familiarity with the guidelines or to
special considerations about the patient's medical condition which are not known
to the dentist. In this situation, the dentist is encouraged to consult with the
physician to determine if there are any special considerations that might affect
the dentist's decision on whether or not to premedicate, and may wish to share a
copy of these guidelines with the physician, if appropriate. After this
consultation, the dentist may decide to follow the physician's recommendation,
or, if in the dentist's professional judgment, antibiotic prophylaxis is not
indicated, may decide to proceed without antibiotic prophylaxis. The dentist is
ultimately responsible for making treatment recommendations for his/her patients
based on the dentist's professional judgment. Any perceived potential benefit of
antibiotic prophylaxis must be weighed against the known risks of antibiotic
toxicity, allergy, and development, selection and transmission of microbial
resistance.
This statement provides guidelines to supplement practitioners in their clinical
judgment regarding antibiotic prophylaxis for dental patients with a total joint
prosthesis. It is not intended as the standard of care nor as a substitute for
clinical judgment as it is impossible to make recommendations for all
conceivable clinical situations in which bacteremias originating from the oral
cavity may occur. Practitioners must exercise their own clinical judgment in
determining whether or not antibiotic prophylaxis is appropriate.
