dc.description.abstractVital bleaching is a couservative procedure for teeth that have intrinsic stains but are otherwise normal. This paper reviews the literature, presents the clinical procedure using a bleaching light (Union Broach) and H202 35% and discusses a quantitative study of color changes which occurred in twelve patients that underwent treatment. The baseline color was recorded numerically using a Minolta Chromameter CR100. Color photographs were also taken. The results of the Chromameter readings before and six months after treatment showed the following mean changes: *L = 8.58 *a = -1.25 *b = 6.88. These values at 1% significance level and at II degrees of freedom represent a significant change according to the Paired "t" test. The analysis of repeated measures ANOVA with multiple comparison procedures, showed that this is a significant study at the least significant difference. Clinical evaluations correlating with Chromameter readings indicate that vital bleaching is an effective procedure for most of the patients with intrinsic stains. The use of the bleaching light reduces valuable chair time for the clinician.en_US
