EVALUATION OF THE ADHESIVE INTERFACE BETWEEN ENAMEL AND A SINGLE-COMPONENT ADHESIVE APPLIED IN SELF-ETCHING AND SELECTIVE-ETCHING PROCEDURES
Abstract
Aim of the study The aim of this study was to analyze the adhesive joint with enamel for a single-component
system which can be used in either self- or selective-etching procedures. Material and methods The study
group included 10 extracted third molars. Class V cavities were prepared in both lingual and labial surface and
restored using a composite resin (Filtek Z550, 3MESPE) and the adhesive Single Bond Universal (3M ESPE).
For the facial cavities, the adhesive was applied using a total-etch procedure. In the lingual cavities no etching
gel was applied. The prepared teeth were split in an axial linguo-facial direction. The sections were observed by
scanning electron microscopy using a VEGA II LSH (TESCAN) microscope. Results The images have showed
that an adhesive joint was formed between composite and enamel regardless of the chosen technique (with or
without etching). The adhesive layer interposed between the enamel and the composite resin was thicker in most
samples were the specimens were subjected to acid etching. Conclusions Phosphoric acid pre-treatment could
be beneficial for bonding to enamel when using mild self-etching adhesive systems.
