Design outcomes

Primary

MeasureTime frame
The primary target value is the plaque record control (PCR) value. This is a value that indicates the teeth affected with plaque in comparison to the plaque-free tooth areas as a percentage value. The PCR value is collected at both the 1st and 2nd session by staining the tooth surfaces with a colour solution.

Secondary

MeasureTime frame
The secondary target value is the Ginigval Bleeding Index (GBI). This is a value that provides information about gum health. The GBI value is determined at both the 1st and 2nd session by running a blunt probe along the transition between the tooth and the gum. The GBI value is also a percentage value.
