dental hardware other constituents may also be components of the cleaning solution the illustration of the cleaning chamber as shown in fig1 is intended to depict the major elements of this assembly for describing the general process itself additional details of the cleaning chamber are provided in fig2 2 a 2 b and 2 c further descriptions of these figures will be provided hereinafter again with reference to fig1 the cleaning chamber within which the aqueous cleaning solution and the dental hardware are placed is comprised of an upper section 37 and a lower section 36 both sections are constructed in major part out of a thermoplastic material the upper section 37 is domed having a central flat circular segment about its vertical axis and has a first surface reflective material 39 a affixed to its interior surfaces for reflecting incident uv light rays the cleaning chamber lower section 36 also has a first surface reflective material 39 b affixed to its interior surfaces similarly intended to reflect incident uv light rays lower section 36 is also constructed to include window 35 as an integral component both chamber sections join by friction fit 38 around their respective perimeters such that this friction fit creates a leak tight seal thereby preventing the aqueous cleaning solution 57 from leaking or otherwise escaping from the assembled cleaning chamber during operation the uv light rays 34 emitted by ccf lamp 33 pass through the fixed enclosure window 65 and cleaning chamber window 35 irradiating the cleaning solution.
