ABSTRACT


Aim

Self-etch bonding systems have been introduced recently and have the advantage of reduced operating time.
Because of patient management and isolation difficulties in children, the present study aimed to evaluate microtensile bond
strength of two self-etch bonding systems (AdheSE and Xeno III) on cleaned only, ground and sandblasted enamel.

Methods

Thirty intact primary molars were selected and randomly divided into two groups according to
the type of bonding used (Xeno III and AdheSE). The teeth were divided into three subgroups according to enamel
surface conditioning method: prophylaxis with pumice, grinding with coarse finishing and polishing disc, and sandblasting
with aluminum oxide particles. Tetric Ceram composite then was applied. Samples were sectioned coronally and axially. The
interface area of dental sticks was measured and specimens were subjected to a tensile force of 0.5 mm/min until failure.

Results

Microtensile bond strength of Xeno III-sandblasting, AdheSE-sandblasting, AdheSE-grinding, and AdheSE-
cleaned only were 25.57.7, 21.22.3, 12.92.2, and 9.11.1, respectively. During sectioning,
all specimens of Xeno III-cleaned only and Xeno III-grinding groups were fractured. CONCLUSIONS: Two step
AdheSE yields higher mTBS in comparison to one step Xeno III. In regard to surface conditioning, sandblasting
increases the mTBS relative to grinding with finishing and polishing disc, and the cleaned-only enamel has the lowest
mTBS.
