Abstract: The present invention provides a calcified tissue facing preparation characterized by having a polymerizable resin, and an antimicrobial agent of the formula: where R1 is a hydrocarbon radical having between 1 and 16 carbon atoms, n is an integer between 1 and 8 inclusive and X is a halogen atom selected from fluorine, chlorine or bromine. It is appreciated that R1 includes unsaturated hydrocarbon radicals, as well as heteroatom containing radicals. Preferably, the molecule of Formula (I) is associated with an adduct species. At least one of glutaraldehyde or a chelating agent are added to enhance the preparation characteristics.

Abstract: A dental bonding formulation provides a single application step in which a chelating agent present within the formulation is capable of complexing ions present in a dentinal tubule calcified deposit. The formulation has a pH of between 1.2 and 4 to promote complexation without inducing excessive dentin etch. A curable resin is also present in the formulation to seal the underlying dentin surface.

Abstract: The present invention provides a calcified tissue facing preparation characterized by having a polymerizable resin, and an antimicrobial agent of the formula: 1

Abstract: The present invention provides a calcified tissue facing preparation characterized by having a polymerizable resin, and an antimicrobial agent of formula (I) where R1 is a hydrocarbon radical having between 1 and 16 carbon atoms, n is an integer between 1 and 8 inclusive and X is a halogen atom selected from fluorine, chlorine or bromine. It is appreciated that R1 includes unsaturated hydrocarbon radicals, as well as heteroatom containing radicals. Preferably, the molecule of formula (I) is associated with an adduct species. A solvent and the complementary spectrum antimicrobial benzalkonium chloride are also optionally added. An antimicrobial oral rinse excluding the polymerizable resin contains at least 0.2% by weight of the antimicrobial agent.

Abstract: A dental impression tray having a pair of spaced and outwardly flared sidewalls with a layer of material, such as gauze, netting, plastic or the like, or a rigid material, extending perpendicularly between the sidewalls. The sidewalls, furthermore, are dimensioned to extend substantially a one-half arch of a dental occlusion. The layer of material, however, extends outwardly from one end of the sidewalls so that the layer extends substantially a three-quarters of an arch of a dental occlusion. The dental impression tray is easily convertible between a one-half arch and a three-quarters arch of a dental occlusion by selectively removing the outwardly extending portion of the layer material. Additionally, a frame connects the sidewalls together while a notch in the frame enables the sidewalls to deflect upon occlusion and remain in a deflected position. Optionally, the sidewalls are eliminated.

Abstract: A dental composite is disclosed which is made of a light curable material containing filler particles suspended in the light curable material. The filler particles are formed from material that has been previously cured and then reduced in size, preferably by grinding, to a predetermined range of particle sizes.

Abstract: A method for making a custom impression tray is disclosed. The method includes the steps of heating a thermosetting material, such as polycaprolactone until the material becomes pliable and then molding the material in the area of the mouth for which a custom impression tray is desired. The material, upon cooling, sets thus forming a custom impression tray which is then removed from the mouth.
