Materials and Methods. The investigators
prepared Class II cavities in 60 extracted human premolars.
They performed conventional endodontic therapy using a resin-based sealer
andgutta-percha points. They randomly assigned each tooth to a group
receiving one of the following adhesives: Adper Prompt L-Pop (3M ESPE,
Seefeld, Germany), Clearfil SE Bond (Kuraray, Osaka, Japan), FL Bond
(Shofu, Kyoto, Japan), Single Bond (3M ESPE) or Xeno III (Dentsply De
Trey, Konstanz, Germany). They restored all teeth with resin-based composite material (Z250, 3M ESPE). Specimens underwentthermocycling and
dye penetration and were sectioned longitudinally. The authors photographed the sections under a stereomicroscope. They transferred the
images to an IBM-compatible personal computer for quantitative assessment of dye penetration using image analysis software. They analyzed data
by means of Kruskal-Wallis and Mann-Whitney U tests (P = .05) and evaluated two specimens from each groupunder scanning electron microscopy.
Results. None of the tested self-etch adhesives completely eliminated
microleakage. Dye leakage was restricted to the coronal cavity walls; it did
not migrate toward the pulp chamber or toward the root canal. Single Bond
and Clearfil SE Bond showed significantly lower dye penetration values at
occlusal and gingival margins.
Conclusions. The coronal sealingperformance of the tested self-etch
adhesive systems in endodontically treated teeth was material-dependent.
The use of Clearfil SE Bond in such teeth can help achieve a marginal seal
comparable to that achieved with Single Bond.
Key Words. Self-etch adhesive; microleakage; endodontically treated
teeth; total-etch adhesive.
