What is the True Incidence of Dental Pathology in the Total Joint Arthroplasty Population?

One million total joint arthroplasties (TJAs) are performed annually in the United States. The incidence of oral disease has not been documented in this population. To understand the scope of disease, a descriptive longitudinal population-based study sought to define the true incidence of dental pathology in the TJA population. One hundred consecutive TJA patients from a dedicated arthroplasty practice were sent for dental clearance, including oral examination, cleaning, radiographs, and treatment of active decay. The incidence of pathology was documented. Of 10 patients, 23 (23%) were treated before being cleared for arthroplasty. Sixty-six procedures were performed—2.9 problems per patient. No patient developed TJA infection. Routine preoperative dental clearance revealed 23% incidence of pathology, and no patient developed TJA infection.
