Preoperative Oral Health Screening in Patients Undergoing Hip and Knee Arthroplasty: A Cross-Sectional Study

Aim of study was to assess the prevalence and distribution of oral infections potentially leading to bacteriemia in patients scheduled for hip and knee arthroplasty. Materials and Methods: This prospective research was performed on a study group of 51 patients (mean age 67.51+/-5.78 years; 21-males, 30-females) diagnosed with hip osteoarthritis and knee osteoarthritis, scheduled for hip or knee arthroplasty in Clinical Rehabilitation Hospital (Iasi, Romania). A dental specialist performed a standardized clinical and paraclinical intraoral examination on all patients. The following conditions were assessed as oral sources of infection: chronic periapical lesions, endo-periodontal lesions, deep periodontal pockets, residual roots, fixed prosthetic restorations with inadequate marginal adaptation. Results: All patients were diagnosed with periodontal disease. Chronic periapical lesions (23.5%) and endo-periodontal lesions (41.2%) were frequently in maxillary molars. Residual roots were detected in 84.3% of patients (mostly in mandibular molars) while ill-fitting fixed prosthetic restorations in 64.7% of patients. Periodontal treatment of deep periodontal pockets was the most commonly treatment need, followed by replacement of ill-fitted fixed prosthetic restorations, and tooth extraction. Conclusions: Oral infectious foci-associated pathologies were frequent among patients scheduled for hip or knee arthroplasty, with deep periodontal pockets being the most frequent source of oral infection, followed by residual roots and ill-fitted fixed prosthetic restorations. Our results emphasize the necessity of the preoperative oral health evaluations for patients scheduled for hip and knee arthroplasty, a therapeutic approach required especially in the case of those with comorbidities or with risk of systemic bacteriemia of dental origin.
