Icon Caries Infiltrant
Arrest progression of early carious lesions and remove white spots in one visit without drilling.
DMG America introduces an entirely new, revolutionary approach to treating incipient caries—Icon, a caries infiltrant. Until now, dental professionals had only two options for treating caries: fluoride and other remineralization therapies, if the caries was not too advanced, or the “wait and see” approach until it was time to “drill and fill.” Caries infiltration is a major breakthrough in microinvasive dentistry that fills, reinforces, and stabilizes demineralized enamel without drilling or sacrificing healthy tooth structure. Icon provides a highly esthetic alternative to microabrasion and other restorative treatments for cariogenic white-spot lesions.
Icon-Proximal can be used for proximal lesions with noncavitated enamel and a maximum radiographic lesion depth not exceeding the outer third of the dentin. The proximal patient pack contains all of the materials required for treating one patient with two carious lesions, arranged according to the treatment steps. The kits include specially designed dental wedges for making difficult-to-reach interproximal areas accessible, Proximal Tips or carriers for the materials, individual syringes filled with Icon-Etch, Icon-Dry, and Icon-Infiltrant, along with written and diagrammatic instructions.
Before treatment, the tooth should be thoroughly cleaned and isolated with a rubber dam. Rubber dam isolation is highly recommended to maintain a dry field and allow the infiltration to work. The first step is inserting the specially designed dental wedges (Figure 1) to slightly separate the carious tooth from adjacent teeth. After wedge placement, a specially designed tip, called the Proximal-Tip, is loaded with a 15% hydrochloric gel (Figure 2). The tips are ultrathin, perforated film-like carriers that are flexible, can be turned 360°, and allow for safe and precise application of the acid-etch and infiltrant. Once loaded, the tip is placed between the teeth and left in contact for 2 minutes to remove the pseudo-intact surface layer and expose the pore system or chambers of the lesion. After rinsing with water for 30 seconds and air drying, Icon-Dry ethanol is applied and allowed to set for 30 seconds, further drying and disinfecting the area (Figure 3). If any fluid is left on the porous tooth surface, it will inhibit penetration of the caries infiltrant into the lesion.
Next, another tip is loaded with the Icon-Infiltrant, which comes in a special screw-type applicator to ensure the material is gently and slowly extruded onto the tooth. The Icon-Infiltrant, a special resin that works via capillary action, is applied in two steps (Figure 4). The first application is allowed to sit for 3 minutes so it penetrates deeply into the lesion. Excess material is removed with dental floss, and the area is light-cured from three angles for a total of 40 seconds (Figure 5). A second layer of the Icon-Infiltrant is applied, allowed to sit for an additional minute, and light-cured for 40 seconds.
The Icon system stops progression, stabilizes, and seals the carious lesion, visually removing white spots, without changing the anatomical shape of the tooth.
Icon is available in mini-kits that include two patient packs or kits (Cubes) of seven patient packs. Everything necessary for treatment, except for the rubber dam, comes in the package.
