A low-concentration formulation of an active enamel substance, such as an enamel matrix, enamel matrix derivative and/or an enamel matrix protein, is intended to be used as a therapeutic, as a prophylactic and/or as a cosmetic agent. The active enamel substance is incorporated into a polymeric matrix, which is either suitable for cellular in-growth, or is cell-occlusive, so that it is released by degradation of the polymeric matrix, by enzymatic action and/or by diffusion. A new pharmaceutical and/or cosmetic formulation of an active enamel substance is provided at a lower total concentration within the formulation, wherein a spatial and/or selective regulation of release of said active enamel substance permits a greater percentage of the active enamel substance to be released at the time of appropriate cellular activity. |
