摘要
Introduction: Joint implant infection rates range between 0.5% and 3%. Contamination may be hematogenous, originating in oro-dental infection and, as in endocarditis, antibiotic prophylaxis has been recommended to cover oro-dental surgery in immunodepressed patients with joint implants less than 2 years old, despite the lack of any formal proof of efficacy. In this context, the cost and side effects of such prophylaxis raise the question of its real utility.
Materials and methods: A search of Pubmed was performed using the following keywords: prosthetic joint infection, dental procedure, antibiotic prophylaxis, hematogenous infection, dental infection, bacteremia, and endocarditis. Six hundred and fifty articles were retrieved, 68 of which were analyzed in terms of orthopedic prosthetic infection and/or endocarditis and oro-dental prophylaxis, as relevant to the following questions: frequency and intensity of bacteremia of oro-dental origin, frequency of prosthetic joint infection secondary to dental surgery, and objective efficacy of antibiotic prophylaxis in dental surgery in patients with joint implants.
Results: Bacteremia of oro-dental origin is more frequently associated with everyday activities such as mastication than with tooth extraction. Isolated cases of prosthetic contamination from dental infection have been reported, but epidemiological studies in joint implant bearers found that absence of antibiotic prophylaxis during oro-dental surgery did not increase the rate of prosthetic infection. The analysis was not able to answer the question of the efficacy of dental antibiotic prophylaxis in immunodepressed patients; however, oro-dental hygiene and regular dental treatment reduce the risk of prosthetic infection by 30%.
Discussion and conclusion: The present update is in agreement with the conclusions of ANSM expert group, which advised against antibiotic prophylaxis in oro-dental surgery in implant bearers, regardless of implant duration or comorbidity: the associated costs and risks are disproportional to efficacy.
Level of evidence and type of study: Level V; expert opinion.
