In two experiments, each running for 2 weeks, plaque formation was studied on forty-two teeth acting as abutments for removable partial dentures. In the first experiment, only ordinary tooth brushing was practised. Plaque accumulation was rapid, yielding scores ranging between 2 and 5. In the second experiment, following instruction in intensive tooth brushing, plaque scores were depressed to approximately 1.5 and below.
