Currently, there is considerable interest in biodegradable films that release drugs as a therapeutic device (Ahuja et al., 2003, 2006), and the films prepared in this work would be one alternative for new investments in minimally invasive therapies in the dental area. Other studies are being conducted to assess the moisture con- tent, thickness, color and opacity, mechanical properties (tensile strength and elongation), water solubility and vapor water perme- ability (PVW and thermal gravimetric analysis) of the films.
