Comparison between one-step self-etch adhesive and along with additional hydrophobic layer in the retention of giomer at non-carious cervical lesion

Abstract

The purpose of the present study was to assess the giomer retention following application of one step self etch adhesive and one-step self-etch adhesive plus an extra hydrophobic adhesive layer in non-carious cervical lesion. Twenty four participants having bilateral cervical lesion at the maxillary premolars teeth were selected. Following cleaning of the cervical lesions, 24 left premolar teeth were restored with giomer by using the one-step self-etch system (Group A) and 24 right premolar teeth were restored with giomer by using one-step self-etching plus extra hydrophobic adhesive layer (Group B). Participants were recalled at 6 and 15 months for evaluating the clinical outcome. The results showed that at 15 months, 18 giomer restorations in Group A and 21 in Group B were intact inside the cavity and no significant difference was found between the two groups. It can be concluded that giomer restoration used with one-step self- etching plus additional adhesive layer slightly improved the retention of the material.
