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 person's teeth, or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray and placed over the person's 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 person's teeth as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking of the tray over the person's teeth. The dental compositions may further include anticariogenic and antimicrobial agents.

An improved method and system for attaching a welded wire grid-work panel to a plurality of face panels of a retaining wall. The method first begins by providing a plurality of stackable face panels, each face panel having a plurality of anchor links fixed within a back portion of the face panels. Each of the anchor links forms a vertical loop extending outwardly generally perpendicular to the back portion of the face panels. Additionally, each anchor link includes two legs extending laterally from each anchor link within the face panel. Next, a first tier of the face panels is disposed at the bottom of the embankment being erected. Soil is then back-filled behind the first tier of panels to a level of the anchor links disposed within the first tier of face panels. A welded wire grid-work panel, which extends perpendicularly from the back portion of the face panels into a soil embankment, is positioned so that a plurality of wire loops at the edge of the grid-work panel aligns with the vertical loops. A connector rod is extended through the vertical loops of the anchor links and the wire loops of the grid-work panel. Next, additional soil is back-filled behind the first tier of face panels and over the anchor links, vertical loops, wire loops, and grid-work panel to a level at a top edge of the first tier of face panels. The method is repeated until the desired height of the embankment is attained.

Stackable weight plates comprised of a front and a rear lateral faces with a protrusion at a proximal radial center of the front lateral face and corresponding recess at a proximal radial center of the rear lateral face is provided. The rear lateral face with the recess section at the proximal radial center of a top weight plate in a stack may rest (or be stacked) on the front lateral face with the protrusion at a proximal radial center of another weight plate. Because each plate is restrained along its center axis by the mating or interlocking of the protruded area of one plate with the recessed area of another weight plate, the stacked plates are therefore generally stable and do not fall due to lateral shearing of the stack. When mounted on a handle bar to form an inertial force exercise device, the recessed area of the rear lateral face of the weight plates of the present invention house the mounting or fastener mechanism.
