, mesh size is larger sized when compared to the drug molecules: the whole release method is controlled by diffusion. It's the case of small drug molecules which diffuse freely from the network, as well as their migration is not depending on the mesh dimensions;
In current decades, for the therapy of oral diseases, which include periodontitis, viral or fungal bacterial infections, solutions with the possibility of releasing drugs instantly into the oral cavity are actually applied.
