PERFECT SMILE CORPORATION ANNOUNCES RESULTS OF UNIVERSITY TEETH WHITENING STUDY

Cleveland, Ohio, April 12, 2005 -- Perfect Smile Corporation today announced specific results from a clinical study in which its Perfect Smile “click & brush-on” Teeth Whitening Pen outperformed leading competitive products in a study recently conducted at Case Western Reserve University.

The study was conducted at the University’s MicroDesign Center utilizing an X-Rite Corporation Shadevision scanner to measure changes in whiteness resulting from whitening products applied to bovine teeth.  The whitening products evaluated in the study were Crest White Strips, Colgate Simply White, and the Perfect Smile Whitening Pen (formerly EnamelWhite™).

Study results indicated that Perfect Smile outperformed the competitive products by a range of 14% - 82% utilizing data considered to be reliable by X-Rite Corporation technical staff.  Results using all data compiled from the study showed that Perfect Smile outperformed the competitive products by 20% - 77%.

Dr. Robert O. Wolf, creator of the Perfect Smile Whitening Pen, stated “we are very pleased with the study results which clearly place our product at the front of the line compared to teeth whiteners widely available in retail stores.  The Invisible Film-Forming technology contained in our water soluble, pH neutral gel formulation, combined with the unique brush pen delivery method, creates a superior product with virtually zero sensitivity that is also the most cost effective, convenient and easy-to-use whitening product available in the market today.”
