Abstract: An improved method for manufacturing a palatable, aluminum-based anticariogenic composition is described. Critical pH adjustment of aluminum salt solutions is accomplished advantageously by pre-blending the aluminum salt solution with at least a portion of a humectant ingredient component. Cellulosic binder components, when used, are preferably hydrated in the pH-adjusted aluminum/humectant solutions. Consistent product rheology and aluminum availability can be obtained in large-scale preparations by blending the aqueous pH-adjusted aluminum/humectant solution with humectant/surfactant and flavor oil/pH-adjusted surfactant premixes.

Abstract: Improved anticariogenic oral preparations having a pH of about 2.5 to about 5.0 comprise an anticariogenically effective amount of a water-soluble aluminum salt in a surfactant-containing emulsion system suitable for use in the mouth.

Abstract: Anti-calculus oral compositions include an aluminum salt and an aliphatic carboxylic acid or water-soluble salt thereof capable of complexing with the aluminum, together with a carrier suitable for use in the oral cavity. Such compositions exhibit marked effectiveness in inhibiting the formation and growth of calculus on the dental enamel.

Abstract: Improved anticariogenic oral preparations having a pH of about 2.5 to about 5.0 comprise an anticariogenically effective amount of a water-soluble aluminum salt in a surfactant-containing emulsion system suitable for use in the mouth.

Abstract: Incorporation of talc in dentifrice preparations based on calcined kaolins enhances the rheological properties of such dentifrices. In addition, new and more effective dentifrice preparations may be obtained by employing therein a cleaning and polishing constituent comprising a mixture of calcined kaolin, talc and titanium dioxide. Additionally, anticariogenic adjuvants, such as sodium fluoride and stannous fluoride, especially a 1:2 molar mixture thereof, may be incorporated in such dentifrice preparations.

Abstract: The application discloses new dental prophylactic cleaning and polishing agents predominantly comprising magnesium metasilicate particles obtained by thermally treating selected minerals.

Abstract: New and more effective dentifrice preparations may be obtained by employing therein a cleaning and polishing constitutent comprising purified, calcined kaolin particles. Additionally, anticariogenic adjuvants such as sodium fluoride, NaF, may be incorporated in such dentifrice preparations.

Abstract: Improved anticariogenic oral compositions comprise a non-toxic and anticariogenically effective amount of one or more water-soluble alumium salts, a non-toxic stable complexing carboxylic acid or water-soluble salt thereof, and a carrier suitable for use in the oral cavity at a pH of about 7.0-9.0.

Abstract: Improved therapeutic dentifrice preparations comprise a nontoxic and anticariogenically effective amount of one or more water-soluble aluminum salts and a compatible dental abrasive selected from the group consisting of purified, calcined kaolin, calcined aluminum silicate, zirconium silicate, silica, alumina, calcined and uncalcined talcs, barium sulfate, resin abrasives, and mixtures thereof.

Abstract: Aqueous anionic maloaluminate complexes of the structure: ##STR1## at mildly alkaline pH are effective in reducing the incidence and severity of dental caries. These complexes may be advantageously incorporated in aqueous oral compositions, especially dentifrices, having pH values lying in the range of about 7.0 - 9.0.

Abstract: A system and machine, or orbital brushing simulator, especially designed for testing the effect of cleaning and polishing agents and of brushes on tooth or similar specimens, with particular respect to enamel, dentin, or cementum abrasion, enamel or dentin polishing, enamel scratching, and cleaning. The machine accommodates several individually-mounted specimens, each acted upon by a brush moving over it in either of two directions, or in combinations of the two, thereby avoiding grooving of the specimen surfaces as well as providing more flexible and useful patterns for study. The system has a gravity-operated mechanism to set the pressure between each specimen and its brush, which thereby avoids variation in the pressure in a test involving a substantial number of cycles. This means is adjustable to provide very light pressures that are nevertheless steady. Means are provided to maintain a uniform suspension of the cleaning and polishing agent during the testing operation.
