Depending on the disposable prophy angle that you’re using, esa disposable prophy angles may cost less, the same or as much as 25¢ more to buy. However, to properly compare esa to regular disposable angles using a nose cone connection, you must consider the cost of autoclaving the nose cone or straight attachment. When you include the amortization of the nose cone wear, sterilization pouches, cleaning agents and the labor involved in infection control process, esa disposable prophy angles cost about half as much money to use. Based on the average cost of a esa and a traditional disposable prophy angle/connection offices can realize a savings of 50¢ per prophy procedure.
