To reduce the risk of infection after orthopedic surgery, patients are asked to undergo preoperative assessments in various medical domains. However, to our knowledge, there has been no systematic review to evaluate the performance of a preoperative dental assessment before orthopedic surgery. We focus on two questions as follows: (1) is there a link between the presence of preoperative dental assessment and orthopedic infections?; (2) is the probability of an orthopedic infection increased in the presence of dental risk factors and comorbidities?
