BEhavioral EConomics for Oral Health iNnovation Pilot Trial

If both groups are acceptable and feasible, the reward group with toothbrushing outcomes at
least 20% better than the other one (and the control) will be chosen for a future Phase
II/III trial; if they are similar, the fixed monetary reward will be used because it is
simpler to explain, monitor, and implement.
