Abstract
Despite limited evidence for a preoperative dental screening examination and needs-based focal rehabilitation, as well as the need for antibiotic prophylaxis prior to invasive dental procedures, oral health is and remains a relevant topic in arthroplasty. The aspect of oral health should not be neglected in the future in connection with periprosthetic infections and should continue to be the subject of intensive research. The frequency of conspicuous dental findings in middle and old age underlines the importance of this problem. A dental examination prior to arthroplasty implantation can generally contribute to minimizing the risk of arthroplasty infection. It would be desirable for further studies to provide evidence on this topic in order to make recommendations for action. Independently of this, the development of an interdisciplinary guideline (arthroplasty and dentistry) on this topic should be encouraged. This could help to ensure that standardized treatment procedures are integrated into everyday clinical practice across the board.

Antibiotic Prophylaxis Prior to Dental Procedures After Total Hip and Knee Arthroplasty Does Not Decrease the Risk of Periprosthetic Joint Infection. J Arthroplasty 2024; 39:S420-S424. [PMID: 38401610 DOI: 10.1016/j.arth.2024.02.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 02/09/2024] [Accepted: 02/13/2024] [Indexed: 02/26/2024] Open
Abstract
BACKGROUND Periprosthetic joint infection (PJI) is a devastating complication after total hip and total knee arthroplasty (THA/TKA). While some guidelines no longer recommend routine use of prophylactic antibiotics for dental procedures, many surgeons continue to prescribe antibiotics for their THA/TKA patients. In a setting of increasing antibiotic resistance, it is important to reduce unnecessary antibiotic use. This study aims to evaluate antibiotics prior to dental procedures and the association between dental procedures and PJI. METHODS We conducted a retrospective cohort study of patients who underwent THA/TKA between January 1, 2019 and December 31, 2020. The primary outcome was late-presenting PJI, occurring > 90 days after surgery. Patients were designated in the antibiotic group (2,000 mg of amoxicillin) or non-antibiotic group based on their surgeon's prophylaxis protocol. Dental-associated PJIs were considered if the patient had evidence of poor dentition or a recent dental procedure prior to the onset of PJI symptoms. RESULTS There were 2,871 (26.4%) patients in the no antibiotics group and 8,023 (73.6%) patients in the antibiotics group. We found 27 (0.3%) late-presenting PJIs and 4 dental-associated PJIs. In the univariate and multivariable analyses, body mass index ≥-30 and revision surgery were the only variables that increased the odds of late-presenting PJI. All 4 dental-associated PJIs occurred in patients prescribed antibiotics. CONCLUSIONS We found a low rate of late-presenting PJI. Routine antibiotics prior to dental procedures were not shown to affect the risk of late-presenting PJI. These findings suggest that routine antibiotic prophylaxis before dental procedures is not necessary after THA/TKA.

Abstract
BACKGROUND Although the risk of dental procedures as a cause of bacteremia has been recognized, evidence regarding the association between dental procedures and late periprosthetic joint infection (LPJI) is scarce. We sought to determine whether dental procedures are associated with an increased risk of LPJI. METHODS The study was conducted under a case-crossover design using a large claims database in Japan. We identified adult patients who had undergone dental procedures and were hospitalized for LPJI between April 2014 and September 2021. Exposure to dental procedures was assessed during a case period of 1-4 weeks, with two control periods of 9-12 weeks and 17-20 weeks, preceding LPJI hospital admission. Conditional logistic regression models were used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) of LPJI associated with dental procedures in the case period compared with the two control periods. RESULTS In total, 241 patients with LPJI were included in the case-crossover study. At least one dental procedure was performed in 46 patients (19.1%) in the hazard period and in 75 patients (31.1%) in the control periods. The OR for LPJI with dental procedures was 0.96 (95% CI, 0.61-1.53; p = 0.88). Findings were robust in several sensitivity analyses, including stratification by whether the dental procedure included antibiotic prophylaxis. CONCLUSIONS This study suggests that dental procedures are not associated with increased risk of LPJI, and will raise questions about the recommendation for antibiotic prophylaxis before dental procedures.

Abstract
Background The prevalence of revision surgery due to aseptic loosening and periprosthetic joint infection (PJI) following total hip and knee arthroplasty is growing. Strategies to prevent the need for revision surgery and its associated health-care costs and patient morbidity are needed. Therapies that modulate the gut microbiota to influence bone health and systemic inflammation are a novel area of research. Methods A literature review of preclinical and clinical peer-reviewed articles relating to the role of the gut microbiota in bone health and PJI was performed. Results There is evidence that the gut microbiota plays a role in maintaining bone mineral density, which can contribute to osseointegration, osteolysis, aseptic loosening, and periprosthetic fractures. Similarly, the gut microbiota influences gut permeability and the potential for bacterial translocation to the bloodstream, increasing susceptibility to PJI. Conclusions Emerging evidence supports the role of the gut microbiota in the development of complications such as aseptic loosening and PJI after total hip or knee arthroplasty. There is a potential for microbial therapies such as probiotics or fecal microbial transplantation to moderate the risk of developing these complications. However, further investigation is required. Clinical Relevance Modulation of the gut microbiota may influence patient outcomes following total joint arthroplasty.

Clin Orthop Relat Res 2024; 482:411-422. [PMID: 38231150 PMCID: PMC10871784 DOI: 10.1097/corr.0000000000002966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 12/05/2023] [Indexed: 01/18/2024]
Abstract
BACKGROUND The question of whether dental procedures increase the risk of periprosthetic joint infection (PJI) in patients who have undergone total joint arthroplasty (TJA) remains controversial. QUESTIONS/PURPOSES (1) Are dental procedures associated with an increased incidence of PJI in the setting of either primary or revision TKA after controlling for relevant potentially confounding variables? (2) Is the administration of prophylactic antibiotics before dental procedures associated with any differences in this risk? (3) Which factors are associated with increased incidence of PJI after dental procedures? METHODS This nationwide, retrospective, comparative, large-database study evaluated 591,602 patients who underwent unilateral primary or revision TKA between 2009 and 2019 using the Health Insurance Review and Assessment Service data in South Korea, in which all people in South Korea were registered and to which all medical institutions must charge any procedures they performed. The study population was divided into 530,156 patients with dental procedures and 61,446 patients without dental procedures based on whether the patients underwent a dental procedure at least 1 year after the index surgery. After propensity score matching, patients were classified into a dental (n = 182,052) and a nondental cohort (n = 61,422). The dental cohort was then divided into two groups: 66,303 patients with prophylactic antibiotics and 115,749 patients without prophylactic antibiotics based on prophylactic antibiotic use. After propensity score matching, patients were categorized into prophylactic (n = 66,277) and nonprophylactic (n = 66,277) cohorts. Propensity score matching was used to control for covariates including posttraumatic arthritis associated with PJI risk according to the dental procedure and prophylactic antibiotic use among the cohorts. After propensity score matching, the standardized mean difference was confirmed to be less than 0.1 for all variables. Kaplan-Meier survival analyses, log-rank tests, and Cox proportional hazards regression analysis was performed. RESULTS Dental procedures were not associated with an increase in PJI risk after primary (adjusted HR 1.56 [95% CI 0.30 to 8.15]; p = 0.60) or revision TKA (adjusted HR 1.74 [95% CI 0.90 to 3.34]; p = 0.10). Additionally, use of prophylactic antibiotics was not associated with a reduced PJI risk after the index surgery, either for primary (adjusted HR 1.28 [95% CI 0.30 to 5.42]; p = 0.74) or revision TKA (adjusted HR 0.74 [95% CI 0.45 to 1.23]; p = 0.25). Although surgery type and prophylactic antibiotic use exhibited no influence on PJI occurrence after dental procedures, posttraumatic arthritis was associated with PJI. The adjusted HR for posttraumatic arthritis was 4.54 (p = 0.046). CONCLUSION Our findings suggest that dental procedures were not associated with an increased risk of PJI for up to 2 years after the dental procedure in patients who underwent either primary or revision TKA. Based on these findings, there is insufficient rationale for the use of prophylactic antibiotics before dental procedures in patients who have undergone primary or revision TKA.

Abstract
Antibiotic prophylaxis is the use of antibiotics perioperatively to prevent infections at the surgical site or distant locations. The decision to provide prophylaxis must balance risks of antibiotic resistance, adverse drug reactions, and increased health care costs with the benefit of decreasing infection. This determination has been studied extensively in patients with specific cardiac conditions and prosthetic joints. Prophylactic antibiotics in healthy patients have been shown to reduce the frequency of alveolar osteitis and decrease the failure rates of dental implants.

Abstract
BACKGROUND There is a reasonable body of evidence around oral/dental health and implant infection in orthopaedic and cardiovascular surgery. Another large area of surgical practice associated with a permanent implant is mesh hernia repair. This study aimed to review the evidence around oral/dental health and mesh infection. METHODS The research protocol was registered in PROSPERO (CRD42022334530). A systematic review of the literature was undertaken according to the PRISMA 2020 statement. The initial search identified 582 publications. A further four papers were identified from references. After a review by title and abstract, 40 papers were read in full text. Fourteen publications were included in the final review, and a total of 47,486 patients were included. RESULTS There is no published evidence investigating the state of oral hygiene/health and the risk of mesh infection or other infections in hernia surgery. Improvement in oral hygiene/health can reduce surgical site infection and implant infection in colorectal, gastric, liver, orthopaedic and cardiovascular surgery. Poor oral hygiene/health is associated with a large increase in oral bacteria and bacteraemia in everyday activities such as when chewing or brushing teeth. Antibiotic prophylaxis does not appear to be necessary before invasive dental care in patients with an implant. CONCLUSION Good oral hygiene and oral health is a strong public health message. The effect of poor oral hygiene on mesh infection and other complications of mesh hernia repair is unknown. While research is clearly needed in this area, extrapolating from evidence in other areas of surgery where implants are used, good oral hygiene/health should be encouraged amongst hernia patients both prior to and after their surgery.

Abstract
Surgical site infections (SSIs) represent a potential complication in surgical procedures, mainly because clean/contaminated surgery involves organs that are normally colonized by bacteria. Dental, maxillo-facial and ear-nose-throat (ENT) surgeries are among those that carry a risk of SSIs because the mouth and the first respiratory tracts are normally colonized by a bacterial flora. The aim of this consensus document was to provide clinicians with recommendations on surgical antimicrobial prophylaxis in neonates (<28 days of chronological age) and pediatric patients (within the age range of 29 days−18 years) undergoing dental, maxillo-facial or ENT surgical procedures. These included: (1) dental surgery; (2) maxilla-facial surgery following trauma with fracture; (3) temporo-mandibular surgery; (4) cleft palate and cleft lip repair; (5) ear surgery; (6) endoscopic paranasal cavity surgery and septoplasty; (7) clean head and neck surgery; (8) clean/contaminated head and neck surgery and (9) tonsillectomy and adenoidectomy. Due to the lack of pediatric data for the majority of dental, maxillo-facial and ENT surgeries and the fact that the recommendations for adults are currently used, there is a need for ad hoc studies to be rapidly planned for the most deficient areas. This seems even more urgent for interventions such as those involving the first airways since the different composition of the respiratory microbiota in children compared to adults implies the possibility that surgical antibiotic prophylaxis schemes that are ideal for adults may not be equally effective in children.

Abstract
Background: To determine the prevalence of prosthetic joint infections (PJIs) after elective clean hand surgery in order to determine whether prophylactic antibiotics are warranted in patients who have previously undergone total joint arthroplasty (TJA). Methods: All patients undergoing elective clean hand surgery between 2012 and 2018 were retrospectively cross-referenced with patients who had previously undergone a TJA at the same urban academic medical center. Inclusion criteria were any patients who underwent clean hand surgery during the study period who were an adult between the ages of 30 and 90, had a previous TJA, and did not have a previous history of a PJI. All charts were reviewed to collect data on patient demographics, co-morbidities, the type of TJA and hand surgery performed, whether prophylactic antibiotics were used prior to the hand surgery, and whether a PJI occurred within 3 months of the hand surgery. Results: Total of 331 patients (181 females and 150 males) were identified over the 6-year period that met inclusion criteria. In total, 13% of the patients received prophylactic antibiotics prior to their hand surgery and 87% had not. Only 1 case of a PJI occurred within 3 months of a hand surgery. No relationship was identified between the PJI and the hand surgery, nor the need for preoperative antibiotic prophylaxis. Conclusions: Incidence of PJI after clean hand surgery is very low. We do not recommend the routine use of antibiotic prophylaxis in patients undergoing clean elective hand surgery with a history of prior TJA in order to prophylax against a PJI.

Abstract
As the population ages, more and more patients with orthopaedic prostheses (OPs) require dental implant treatment. Surveys of dentists and orthopaedic surgeons show that prophylactic antibiotics (PAs) are routinely prescribed with a very high frequency in patients with OPs who are about to undergo dental procedures. The present study aims to determine the need to prescribe prophylactic antibiotic therapy in patients with OPs treated with dental implants to promote their responsible use and reduce the risk of antimicrobial resistance. An electronic search of the MEDLINE database (via PubMed), Web of Science, LILACS, Google Scholar, and OpenGrey was carried out. The criteria used were those described by the PRISMA® Statement. No study investigated the need to prescribe PAs in patients with OPs, so four studies were included on the risk of infections of OPs after dental treatments with varying degrees of invasiveness. There is no evidence to suggest a relationship between dental implant surgeries and an increased risk of OP infection; therefore, PAs in these patients are not justified. However, the recommended doses of PAs in dental implant procedures in healthy patients are the same as those recommended to avoid infections of OPs.

J Clin Periodontol 2021; 48:1270-1280. [PMID: 34189757 PMCID: PMC8457097 DOI: 10.1111/jcpe.13514] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Accepted: 06/19/2021] [Indexed: 11/29/2022]
Abstract
AIM To identify invasive dental procedures as a risk factor for postoperative spinal infection (PSI) and evaluate the effectiveness of antibiotic prophylaxis. MATERIALS AND METHODS We analysed 229,335 patients who underwent spinal surgery with instrumentation from 2010 to 2017, using the nationwide database. The incidence of spinal infection 2 years after surgery was determined. Invasive dental procedures as a risk factor for PSI and the effects of antibiotic prophylaxis during this period were also analysed. RESULTS A total of 15,346 patients (6.69%) were diagnosed with PSI. It was found that advanced age, male sex, and a high Charlson Comorbidity Index were risk factors for PSI. The risk of PSI did not increase following dental procedures (adjusted hazard ratio [HR] 0.850; 95% confidence interval [CI], 0.793-0.912) and was not affected by antibiotics (adjusted HR 1.097; 95% CI, 0.987-1.218). Patients who received dental treatment as early as 3 months after spinal surgery had the lowest risk of postoperative infection (adjusted HR 0.869; 95% CI, 0.795-0.950). CONCLUSIONS Invasive dental procedure does not increase the risk of PSI, and antibiotic prophylaxis before dental procedure was not effective in preventing spinal infection.

Abstract
Dentists prescribe 10% of all outpatient antibiotic prescriptions, writing more than 25.7 million prescriptions per year. Many are for prophylaxis in patients with prosthetic joint replacements; the American Dental Society states that "in general," prophylactic antibiotics are not recommended to prevent prosthetic joint infections. Orthopedic surgeons are concerned with the risk of implant infections following a dental procedure and, therefore, see high value and low risk in recommending prophylaxis. Patients are "stuck in the middle," with conflicting recommendations from orthopedic surgeons (OS) and dentists. Unnecessary prophylaxis and fear of lawsuits amongst private practice dentists and OS has not been addressed. We review The American Heart Association/American College of Cardiology, American Dental Association, and American Association of Orthopedic Surgeons' guidelines on dental antibiotic prophylaxis for the prevention of endocarditis and prosthetic joint infections. We provide experience on how to engage private-practice dentists and OS in dental stewardship using a community-based program.

Abstract
Objective Fusobacterium nucleatum is an anaerobic gram‐negative bacilli that is one of the oral and other mucosal surface microbiota. It involves a wide range of human diseases and was first found in periodontal diseases, but reports of bone‐related infections caused by F. nucleatum are rare, especially periprosthetic joint infections (PJI). Methods Here, we present the first case of acute hematogenous PJI of the hip joint caused by F. nucleatum, and debridement, antibiotics, and implant retention (DAIR) was performed. Results The patient was successfully treated with DAIR, identification of isolates by metagenomics next‐generation sequencing was confirmed by polymerase chain reaction. Conclusions For stable acute hematogenous PJI after hip replacement, quick and accurate diagnosis, the identification of pathogenic microorganisms, and the use of DAIR combined with sufficient sensitive antibiotics have a certain clinical effect and can achieve the purpose of both preserving the prosthesis and infection control.

A Systematic Review of the Literature. J Bone Jt Infect 2020; 5:7-15. [PMID: 32117684 PMCID: PMC7045525 DOI: 10.7150/jbji.40096] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2019] [Accepted: 11/13/2019] [Indexed: 12/29/2022] Open
Abstract
Background: The indication of prophylactic antibiotics prior to dental procedures for non-infected causes in order to reduce the risk of haematogenous periprosthetic joint infection (PJI) remains as controversial. We performed a systematic review of the literature assessing the relationship between PJI and invasive dental procedures and whether there is evidence to support the use of antibiotic prophylaxis. Methods: This review was conducted in accordance with the 2009 Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. MEDLINE, EMBASE and the Cochrane Database of Systematic Reviews were searched for studies focusing on dental procedures after TJA, reporting on PJI as an outcome. The methodological quality was assessed with the Newcastle-Ottawa quality assessment scale for case-control and cohort studies and by the tool proposed by Murad et al. for observational studies. Results: Our systematic literature review yielded 90 individual studies, of which 9 met the inclusion criteria. The overall infection rate ranged from 0.26% to 2.12%. Of these, cases associated with a dental procedure ranged from 0% to 15.9%. Five of the studies described cases in which antibiotic prophylaxis was administered; however, no clear algorithm regarding type and dosage of antibiotic was mentioned. When assessing the methodological quality of the evidence, all studies had an overall low to moderate quality. Conclusion: The current systematic review, mostly composed of low-quality studies, suggests that there is no direct evidence to indicate prophylactic antibiotics prior to dental procedures in patients with TJA. In line with the current guidelines, no prophylaxis should be used on interventions for non-infected causes, except for occasional unusual situations, which can then be judged individually.

Abstract
We present the case of a 92-year-old man with septic arthritis of a prosthetic hip joint due to Streptococcus salivarius one week following a high-risk dental procedure despite preprocedure amoxicillin. S. salivarius is a commensal bacterium of the human oral mucosa that is an uncommon cause of bacteremia. S. salivarius has previously been described as a causative agent of infective endocarditis and spontaneous bacterial peritonitis but was only recently recognized as a cause of prosthetic joint infection. This case highlights the potential pathogenicity of a common commensal bacteria and the questionable utility of prophylactic antibiotics before dental procedures to prevent periprosthetic joint infections.

Abstract
BACKGROUND The global rise in infectious disease has led the Center for Disease Control and Prevention and the World Health Organization to release new guidelines for the prevention of surgical site infection. METHODS In this article, we summarize current recommendations based on level of evidence, review unresolved and unaddressed issues, and supplement them with new literature. RESULTS Although the guidelines discuss major issues in reducing surgical site infection, many questions remain unanswered. CONCLUSION These guidelines will hopefully help in setting a standard of care based on best evidence available and focus investigators on areas where evidence is lacking.
