Frequent dental scaling for improved results after total knee arthroplasty

Research from Taiwan has showed that frequent and regular dental scalings (cleanings) are associated with a decreased risk of infection after total knee arthroplasty (TKA). The data analysis showed that patients who received dental scaling had a 20% lower risk for infection than patients who did not get scaling. The more frequently patients got scaling the lower their risk for infection.
