Objectives: The aim of this in vitro study was to

evaluate the surface roughness of enamel after different

bleaching agents procedure and to determine the effect

of fluoride and bonding agent application on the

roughness of bleached enamel. MATERIAL AND

METHODS: Forty-nine dental slice (5×5 mm) polished

enamel surfaces were randomly assigned to 7 groups

(n=7). All the slices were stored in sterilized saliva at

37°C. In group 1 slices were kept untreated (control

group). The surfaces of the slices were treated with 30%

carbamide peroxide (3M White & Brite) (group 2-3-4),

or 38% hydrogen peroxide (Ultradent Opalesence Boost)

(group 5-6-7) for 20 minutes according to the manu-

facturers instructions. Group 2 and group 5 were only

bleached. Neutral fluoride (Denti-Care Denti-Pro Gel

2% Neutral Sodium Fluoride) was applied to the

bleached surface of the groups 3 and 6. The bleached

surfaces of the groups 4 and 7 were covered with

bonding agent (Kuraray Protect Bond). Surface rough-

ness of the specimens were analyzed with a profilometer

(Taylor Hobson, UK). Data were subjected to analysis

of Tukey test (p>0•05). RESULTS: There were no

statistically significant differences between the surface

roughness of untreated control specimens and the

specimens treated with the bleaching materials, fluoride

gel and dental bonding agent (p>0.05).
