摘要： Included are embodiments of product performance and perception modeling. At least some embodiments include receiving a product geometry for a simulated toothbrush, the product geometry defining a physical product characteristic of the simulated toothbrush, receiving an environmental geometry for a simulated mouth, the environmental geometry defining a physical mouth characteristic and a perspective characteristic of the simulated mouth, and applying a simulated plaque indication layer in the simulated mouth. Similarly, some embodiments include applying a predetermined brushing stroke of the simulated toothbrush in the simulated mouth, determining sensory performance of the simulated toothbrush from the predetermined brushing stroke, and generating a scorecard indicating the sensory performance of the simulated toothbrush.

摘要： A head for an oral care implement has an outer rim and an inner portion. The head comprises at least one tuft of filaments of a first type and at least one tuft of filaments of a second type. The at least one tuft of the first type is arranged at the inner portion of the head and comprises a plurality of filaments, each filament having a longitudinal axis and a substantially circular cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The at least one tuft of the second type is arranged at the outer rim of the head and comprises a plurality of filaments, each filament having a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis, the cross-shaped cross-sectional area having four projections and four channels, the projections and channels being arranged in an alternating manner. The at least one tuft of filaments of the second type has a packing factor within a range from about 40% to about 55%.

摘要： A filament for an oral care implement has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels. The projections and channels are arranged in an alternating manner. Each channel has a concave curvature formed by neighboring and converging projections. The concave curvature has a radius, and each projection is end-rounded thereby forming a curvature. The curvature has a diameter, and the ratio of the diameter of the curvature of the projection to the radius of the curvature of the channel is from about 0.2 to about 1.5.

摘要： A head for an oral care implement comprises at least one tooth cleaning element of a first type and at least one tooth cleaning element of a second type. The at least one tooth cleaning element of the first type has a length extension along a longitudinal axis being about 1 mm to about 2 mm longer than the length extension of the at least one tooth cleaning element of the second type along its longitudinal axis. The at least one tooth cleaning element of the first type is a tuft of a first type comprising a plurality of filaments. Each filament has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels, the projections and channels being arranged in an alternating manner. The at least one tuft of the first type has a packing factor within a range from about 40% to about 55%, preferably from about 45% to about 50%.
