Abstract

The purpose of this in vitro study was to determine the effects of three commercially available 10% carbatnide peroxide solutions and a 1.5% hydrogen peroxide solution on enamel surfaces and color. The crowns of forty freshly extracted human teeth were sectioned in half incisogingivally One half ivas bleached for 250 hours total treatment title. The other half of each looth was subjected to the same profoeol in distilled water solutiotis. The eolor of both the treated and eontrol halves was determined using a colorimeter There was no significant difference between any of the control groups, and each treated group was significantly lighter than its corresponding control group. The control and treated halves of samples of each group were then sputter eoated and examined for differences in surface morphology and were compared to enamel etched with 31% phosphoric acid. No significant differences in enamel surface texture were detected between the treated and control enamel surfaces of the teeth in any of the groups. However, the enamel surfaees in all groups differed significantly from conventionally etched enamel.
