Abstract
Extracted human premolars were cut, cleaned and divided into G experim ental groups. Each group was treated with one of the following bleachi ng materials: 30% hydrogen peroxide, 10% carbamide peroxide, sodium pe rborate, Nu-Smile, Opalescence and DentlBright. Morphological changes in tooth surface occurred following treatment with most bleaching agen ts. Hydrogen peroxide and DentlBright were associated with surface cha nges in all dental tissues. Hydrogen peroxide, DentlBright Nu-Smile an d Opalescence were mainly associated with, surface changes in the ceme ntum, which exhibited mule changes than the other tissues.
