AI Technical Summary

Problems solved by technology

While dental trays or toothbrushes can be used to apply hydrophobic lotions, they can be difficult to clean with soap and / or water after use
Strips can be used to deliver lotion compositions, but they are discarded after each use
Additionally, the strip may shift in the mouth after initial placement and during application

Embodiment

[0090] The invention is further illustrated by the following examples which should not be construed in any way as limiting the scope of the invention. After reading the description herein, various other aspects, modifications and their equivalents may suggest themselves to those skilled in the art without departing from the spirit of the invention or the scope of the appended claims.

[0091] Using an in vivo model, applicator devices were screened for uniformity of application of the emulsion composition to the tooth surface and the percentage of emulsion composition transferred from a given applicator to the tooth surface. A blue dye was added to the emulsion composition to facilitate visual and quantitative analysis of various applicator devices.

[0092] and Figure 2A The applicator device was evaluated on a normal toothbrush to show the percentage of transfer of the emulsion compound onto the tooth surface, expressed as transfer efficiency. This was achieved by loading...

Abstract

An applicator device for the application of hydrophobic compositions to hydrophilic surfaces. An applicator device for the application of an emulsion composition to wetted teeth. An applicator tip with at least one external ridge, a plurality of internal ridges, and a plurality of internal channels between the plurality of internal ridges.

Description

technical field [0001] The present invention relates to devices for applying emulsion compositions, such as water-in-oil emulsion compositions, to oral surfaces, such as teeth or gums. The invention also relates to a device for applying a hydrophobic composition to a hydrophilic surface and / or applying a hydrophilic composition to a hydrophobic surface. The invention also relates to methods of using the devices disclosed herein. Background technique [0002] Active agents have been delivered to the oral cavity using various devices such as strips, trays, and the like. However, applying emulsion compositions to many oral surfaces, such as teeth and / or gums, can be challenging. For example, it can be difficult to apply a hydrophobic emulsion directly to a wetted tooth's hydrophilic surface due to energetically disadvantaged hydrophobic-hydrophilic interactions. Unfortunately, many applicators can cause low transfer, smearing, and / or inconsistent application. [0003] Some ...
