Periodontal Composition and Method Abstract A non-aqueous paste or gel dentifrice composition com- prising a water soluble, non-aqueous vehicle having dispersed therein an orally acceptable organic or inorganic peroxide and a bicarbonate salt. The quantities and relative proportions of the peroxide and bicarbonate are sufficient to provide quantities of bactericidally active oxygen upon breakdown of said peroxide by tissue contact and/or by reaction with said bicarbonate in the oral cavity. The bicarbonate also provides a neutral or basic pH upon dissolution of the composition in water. The peroxide and/or bicarbonate is provided with a water soluble barrier coat- ing which is insoluble in the vehicle, to prevent reaction there- between in the absence of water dissolution of the coating. Nor- mal dentifrice adjuvants may also be present, which can similarly be provided with a water soluble barrier coating.
