Topic-the effect of three cavity disinfectants (chlorhexidine gluconate-based. Consepsis; benzalkonium chlorite-based, Tubulicid red; sodium hypochlorite based-Chlorcid V on the self - etch dentine bonding agent ( Adeper Easy One,3M ESPE

The purpose of this study was to determine the effect of three cavity disinfectants (chlorhexidine gluconate-based. Consepsis; benzalkonium chlorite-based, Tubulicid red; sodium hypochlorite based-Chlorcid V on the self -etch dentine bonding agent ( Adeper Easy One,3M ESPE ) under SEM. Method and materials: 30 Class V cavity preparations were prepared on the buccal surfaces of extracted mandibular molars with occlusal margins at the enamel and gingival margins in cementum then they were divided into 3 experimental groups-A,B and C. In the experimental groups, cavities were treated with combinations of one of the three cavity disinfectants with Adeper Easy One, self -etch dentine bonding agent. After the cavity preparations were restored with resin composite Filtek Z 35O (3M ESPE), specimens were thermocycled, , and sectioned the toothresin composite interface of the sectioned specimens was examined under scanning electron microscopy. Results: Consepsis and Tubilicid red specimens shows the resin-tag formation whereas Chlorcid V exhibited marginal gap formations at the tooth-resin composite interface. Conclusion: 2%chlorhexidine gluconate and benzalkonium chlorite can be used as cavity disinfectants with Adeper Easy One SE bonding agent. However sodium hypochlorite is not an appropriate disinfectant to use with this bonding system as it showed marginal gap formation.
