Prepackaged collections of the devices and supplies (i.e., either custom or standard kits) needed for in situ restoration of the appearance, structure and/or function of a patient\'s teeth, requiring light to activate polymerization of the composite resin. Items in these kits usually include a dental syringe, a mixing palette, a mixing pad, brushes, and light-cured composite resin; they may also include liquid etching products and a shade guide. The kits are frequently supplied in supporting trays (i.e., procedure trays) consisting of a flat-bottomed receptacle with a border around the periphery supporting all the instruments and supplies needed for the procedure; the trays are usually covered or wrapped. Light-cured composite resin restorative procedure kits and trays are intended for use in dental offices for dental restoration in highly visible areas (e.g. the central incisors or any other teeth that can be seen when smiling) or in areas where conservation of tooth structure is a top priority.
