Abstract

<p>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.</p>

Highlights

Non-carious cervical lesions occurred due to loss of hard tissues at the cement-enamel junction or its adjoining one-third portion of the crown/ root.[1]
Materials and Methods In Group B, the right permanent premolars were treated according to the following techniques: Study population following application of one-step self-etch adhesive
The adhesive layer may help to preserve the integrity of hybridized dentin, protecting it from polymerization shrinkage stress and acting as a stress absorbing layer

Summary

Introduction

Non-carious cervical lesions (e.g. abrasion, erosion and abfraction) occurred due to loss of hard tissues at the cement-enamel junction or its adjoining one-third portion of the crown/ root.[1]. Fluoride has been added to the materials.[4, 5] Several fluoride-containing materials such as resin modified glass ionomer,[6] compomer,[5] fluoridecontaining resin-based composite,[7] have been developed
