Review of the effectiveness of various tooth whitening systems.
This review compares nine published studies conducted at the Indiana University School of Dentistry. Twenty-five products in four different systems were evaluated using the Trubyte Bioform Color Ordered Shade Guide and a Chroma Meter. The dentist-prescribed overnight bleaching delta mean shade guide value (DSGV) 10 weeks post-bleaching was 13.2 and delta E value (DEV) 4.7; dentist-prescribed daytime bleaching DSGV 10 weeks post-bleaching was 10.5 and DEV 3.4; in-office bleaching DSGV 10 weeks post-bleaching was 6.7 and DEV was 2.1; over-the-counter bleaching DSGV two weeks post-bleaching was 7.2 and DEV was 4.1. A color difference of Delta E 2.6 is perceivable. Tooth whitening is observable with all methods of bleaching. Dentist-prescribed overnight bleaching was shown to be the most effective method of bleaching.
