Abstract:
1. A tissue treatment device, comprising: a handle suitable to be gripped by a hand of a user; a repetitive movement mechanism; a plurality of activated textured surfaces arranged on the device in rows and configured to be activated by the repetitive movement mechanism to apply one or more of agitation and cleaning forces onto a tissue site; and at least one electromagnetic energy output disposed in a vicinity at least partially beneath each of the rows and configured to be activated during activation of the repetitive movement mechanism to direct light into different parts of each of the plurality of activated textured surfaces as the parts of the activated textured surfaces and the at least one electromagnetic energy output are moved relative to each other under influence of the repetitive movement mechanism; wherein the activated textured surfaces comprise bristles of a first height and bristles of a second height greater than the first height, the bristles of the second height being constructed to direct electromagnetic energy through a first region of a dentifrice that is free of a second agent and into a second region of the dentifrice that contains the second agent.
