Study Arms:
- Experimental: Bromelain, Then Placebo (Type: EXPERIMENTAL): Subjects were asked to chew a disclosing tablet, swish, and expectorate. Intraoral photographs were obtained. They then received a vial containing 1 gram of bromelain that was reconstituted with 15ml of pineapple juice at 50 degrees F. Subjects swished the solution in their mouth for 2 minutes and then expectorated. Intraoral photographs were obtained. Subjects then received a toothbrush and were asked to brush their teeth for 2 minutes. Intraoral photographs were obtained. The subjects were then given a Waterpik and instructed to use the appliances to clean their teeth and brackets to the best of their ability, for 2 minutes. Intraoral photographs were obtained. After a 1 week washout period, they received the placebo rinse (powdered sugar), following the same protocol and series of intraoral photographs.
