A method is presented for creating a controller to simulate free motion for a cobot. A cobot is a class of mechanically passive robotic devices, intended for direct physical collaboration with a human operator (Colgate, et al., 1996a). One common cobot application involves a person using the cobot’s endpoint to probe a virtual surface. This task requires that the user have freedom of motion whi...

This in vitro study evaluated the biocompatibility and abrasivity of whitening conventional toothpastes. Samples (non-whitening) - Edel White Infant (EWI) toothpastes Whitening (EWW), CAREFORTE (EWC), Colgate Total 12 Ò Professional (C), Oral-B (OB) were dissolved culture medium (0.2 g sample weight per mL). Human gingival fibroblasts (hGF) placed contact with different dilutions media that had...

The chemical inhibitors act according to the following objectives: to disrupt the metabolism of the bacterial plaque and biochemical mechanisms of it, or to act upon the enamel structure in order to make it more resistant to the action of the bacterial plaque. In terms of the antibacterial activity, we compared toothpastes with different antiplaque chemical inhibitors: Triclosan / Copolymer (TC...
