Stable Light Or Heat Activated Dental Bleaching Compositions
US Patent:
5785527, Jul 28, 1998
Filed:
Jan 10, 1997
Appl. No.:
8/781662
Inventors:
Steven D. Jensen - Midvale UT
Dan E. Fischer - Sandy UT
Dan E. Fischer - Sandy UT
Assignee:
Ultradent Products, Inc. - South Jordan UT
International Classification:
A61C 500
US Classification:
433215
Abstract:
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 patient's 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.
Polymerizable Isolation Barriers With Enhanced Tissue Adherence And Methods For Forming And Using Such Barriers
US Patent:
6048202, Apr 11, 2000
Filed:
Nov 9, 1998
Appl. No.:
9/189006
Inventors:
Steven D. Jensen - Midvale UT
Dan E. Fischer - Sandy UT
Dan E. Fischer - Sandy UT
Assignee:
Ultradent Products, Inc. - South Jordan UT
International Classification:
A61C 514
US Classification:
433136
Abstract:
The polymerizable dental isolation barrier has a monomer and an initiator. The barrier composition has at least one additive including a polymer strength reducer, a wet tissue adherence accentuator, and a reflective material The polymer strength reducer is an organic compound that prevents complete polymerization. The tissue adherence accentuator enables the barrier to adhere to a dental substrate ever after polymerization. The reflective material lowers the reaction rate and lowers the production of excess heat to reduce patient discomfort and to avoid tissue damage.

Dental Bleaching Compositions With High Concentrations Of Hydrogen Peroxide
US Patent:
5858332, Jan 12, 1999
Filed:
Jan 10, 1997
Appl. No.:
8/781858
Inventors:
Steven D. Jensen - Midvale UT

Dan E. Fischer - Sandy UT
Assignee:
Ultradent Products, Inc. - South Jordan UT
International Classification:
A61K 716, A61K 720, C01B 1501, C01B 15055
US Classification:
424 53
Abstract:
Dental bleaching compositions that include a high concentration of bleaching agent and a bleaching agent stabilizer that maintains the potency of the bleaching agent over time. The dental bleaching compositions of the present invention may be one-part, pre-mixed compositions that do not require mixing at the time of treating a patient's 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 stabilizer includes an impurity scavenger that binds or ties up impurities, such as errant or residual metal ions, that can cause decomposition of the bleaching agent. The bleaching agent stabilizer may include a carboxylic acid chelator or a tin salt. The bleaching composition may include a thickening agent to achieve a selected viscosity and a neutralizing agent to adjust the pH and a carrier to help provide selected consistency and potency.

Syringe-Deliverable Neutralizing Barrier
US Patent:
5700148, Dec 23, 1997
Filed:

Appl. No.:
8/408812
Inventors:
Dan E. Fischer - Sandy UT

Steven D. Jensen - Midvale UT
Assignee:
Ultradent Products? Inc. - South Jordan UT
International Classification:
A61K 608
US Classification:
4332171
Abstract:
A syringe-deliverable neutralizing barrier and methods for delivering a composition to form the neutralizing barrier. The neutralizing barrier is formed from a viscous caulking-type material delivered onto a tooth surface to define an etching area while protecting surrounding dental tissues during the application etching solution. The caulking-type material includes a matrix material and a neutralizing agent and has a viscosity such that it is syringe-deliverable yet will intimately and continuously adhere to the tooth surface without substantially flowing after being placed in a desired configuration. The neutralizing barrier is generally water soluble in order to facilitate quick and easy rinsing of the etching solution and neutralizing barrier in order to terminate the etching process, and preparatory to subsequent bonding of a porcelain crown or resinous composite to the tooth or porcelain prosthesis. The neutralizing barrier is particularly useful with etching solutions containing hydrofluoric acid, but can be used for other relatively strong tooth etchants.
