Power Calculation As this is a pilot study it is not possible to perform a power calculation based upon antioxidant outcomes. However, using the primary outcome measure of reduction in probing pocket depth and assuming we can obtain additional PPD reductions of 0.5 mm (or 0.4mm) over non-surgical therapy alone through supplementation with Juice Plus+ capsules, then to have an 80% chance of finding a significant difference at the p<0.05 level we would need to exit 12 (or 17) patients per treatment. This is based on accepted mean PPD reductions for mild to moderate periodontal disease of 1-2mm with non-surgical therapy and data from a study we performed that demonstrated mean PPD reductions of 1.08 + 0.4mm (SD). Recruiting 20 per treatment and allowing for a drop out rate of 20% would still provide sufficient power.
