Abstract
The present study has two objectives: 1. To formulate experimental dentifrices containing different polymers (CHI: chitosan; LPP: sodium linear polyphosphate; MPC: 2-methacryloyloxyethyl phosphorylcholine and Carbopol) associated to fluoride (F-, as NaF) and to fluoride plus stannous (Sn2+, as SnCl2), which will be characterized in terms of pH and fluoride release; 2. To test the efficacy…
