A method for bleaching teeth is disclosed. The method includes the formation of a dental bleaching tray in a one step process that includes placing a moldable material adjacent teeth, permitting the moldable material to cure, and removing the cured moldable material which will then serve as a dental bleaching tray. Dental bleach may be placed into the dental bleaching tray and the tray may be placed onto teeth to accomplish bleaching. The entirety of the process may be performed at a patients home or at a dental office, as desired.

Composition and methods that include potassium nitrate for whitening and/or reducing tooth sensitivity. The dental compositions may optionally include a dental bleaching agent, such as hydrogen peroxide or carbamide peroxide. The dental compositions may be applied directly to the persons teeth, or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray and placed over the persons teeth. In that case, the dental compositions will include a tackifying agent, such as carboxypolymethylene, dispersed within a solvent, which assists the composition in retaining the dental tray over the persons teeth as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking of the tray over the persons teeth. The dental compositions may further include anticariogenic and antimicrobial agents.

Gingival retracting cords including propylhexedrine (e. g. , propylhexedrine HCI) for providing hemostasis and retraction or displacement of gingival tissue. The retraction cords include a hemostatic and tissue stiffening and retraction effective amount of propylhexedrine which avoids the negative side effects associated with the use of epinephrine, commonly used in conventional retraction cords. Retraction cords incorporating propylhexedrine do not cause increased blood pressure or accelerated heart rate. In addition, such retraction cords may include astringents, such as iron (III) salts without causing discoloration of the retraction cord, the patients teeth or gums, or the fingers of the dental practitioner, as would occur if one were to blend epinephrine with iron (III) salts. Water or other appropriate solvents may be used to impregnate, or otherwise treat, the retraction cord with propylhexedrine (e. g. , propylhexedrine HCI).

Dental bleaching compositions are made with a bleaching agent and a stable radiant-energy absorbing compound that acts as a bleaching agent activator. The dental bleaching compositions of the present invention can be one-part, pre-mixed compositions that do not require mixing at the time of treating a patients teeth but which remain stable over time. The bleaching agent may consist of hydrogen peroxide, either in aqueous form or complexed with urea (carbamide peroxide) or sodium perborate. The bleaching agent activator includes hydrocarbons that are stable in the presence of the bleaching agent, which do not prematurely accelerate liberation of the bleaching agent, but which allow for selective activation of the bleaching agent by irradiation of the bleaching composition with radiant energy. The bleaching composition may optionally include a neutralizing agent to adjust the pH, a carrier to help provide proper consistency and potency, and a stabilizing agent to maintain maximum potency of the bleaching agent over time. The bleaching composition may also include a thickening agent to achieve a selected viscosity.

Compositions, method and systems for bleaching tooth surfaces in an accelerated manner. The dental bleaching compositions include a bleaching agent and a stable radiant energy absorbing material that acts as a bleaching agent activator. The dental bleaching compositions of the present invention can be stable one-part compositions that do not require mixing at the time of treating a persons teeth but which remain stable over time. The dental bleaching composition is applied to the labial surface of teeth that are to be bleached. A source of radiant energy is directed onto the treated tooth surfaces to accelerate bleaching activity. The radiant energy source includes a dental light guide having an arcuate light directing member that is positioned in close proximity to the treated teeth. The light directing member has one or more light-emitting panels communicating with a radiant energy generating source that efficiently direct radiant energy onto the treated tooth surfaces. The dental light guide can irradiate all treated teeth of one or both dental arches simultaneously while in a fixed position relative to the one or both dental arches.

Dental bleaching compositions that include perborate bleaching agents, such as sodium perborate monohydrate. The bleaching agent is dispersed within a sticky and viscous carrier such as a mixture of propylene glycol and silica fume. Anhydrous propylene glycol and/or anhydrous glycerin are especially useful in order to maintain the desired degree of hydration of the perborate being used. Flavorants may be added to enhance the taste of the dental compositions, since they will be used within a persons mouth. For best results, a flexible, thin-walled, comfortable-fitting, custom dental tray is used with the dental bleaching compositions. The dental compositions are sufficiently sticky and viscous so as to adhere and retain a dental tray against a persons teeth which is designed so as to not exert significant mechanical pressure onto the persons teeth.

Endodontic sealant compositions and methods for sealing a root canal using sealant or other filling materials. The compositions include one or more resins that promote adhesion to hydrophilic dental tissues. Examples include alkyl methacrylates and derivatives thereof, such as alkylamino methacrylates and oxyphosphoro methacrylates. The compositions include a radio opacifying agent, so that they may be seen using X-rays, and one or more polymerization initiators to effect curing, typically both chemical and photo initiators to yield a dual cure sealant composition. The compositions are introduced into the root canal using a narrow cannula coupled to a high pressure hydraulic delivery device. Additional pressure may be applied to the sealant compositions using a syringe-like plunger introduced within a cylindrical access hole drilled through the crown of the tooth. A curing lamp may be used to cure the top layer of the sealant composition to provide a rigid bonding surface to which a composite resin can chemically bond or adhere.

Examples include alkyl methacrylates and derivatives thereof, such as alkylamino methacrylates and oxyphosphoro methacrylates. The compositions include a radio opacifying agent, so that they may be seen using X-rays, and one or more polymerization initiators to effect curing, at least one chemical initiator and, optionally, a photoinitiator, to yield a curable sealant composition. The compositions are introduced into the root canal using a narrow cannula coupled to a high pressure hydraulic delivery device. Additional pressure may be applied to the sealant compositions using a syringe-like plunger introduced within a cylindrical access hole drilled through the crown of the tooth. The chemical initiator causes the mixed composition to harden over time.
