Abstract
This randomized clinical study was conducted to evaluate the clinical performance -especially recurrent caries incidence - of self-etch adhesive with chlorhexidine versus that of the conventional adhesive without chlorhexidine in class II cavities in high caries risk patients after 1 year follow-up . The study compared Peak® Universal Bond , (Ultradent Products Inc., South Jordan, Utah, USA) served as intervention with Futurabond M+, (VOCO, Cuxhaven, Germany) served as control. A total number of 37 patients with 74 moderate class II carious lesions in vital permanent posterior teeth with no signs of irreversible pulpitis , no history of hypersensitivity, good oral health , same load and force distribution on both sides which means same number of antagonist and adjacent or missing teeth on both sides , were the criteria of inclusion selected. At least two Class II restorations required in each patient and the number of restorations of each material required to be equal in each patient .Condition of patient{u2019}s oral hygiene was enhanced before the study then Patients were randomly allocated. All restorations (37 for each restorative material) were performed by the same operator and same instruments{u2019} type and materials to ensure consistency. Pre-contoured matrix band application was done then the tested adhesive systems were applied according to manufacturer’s instructions onto each quadrant followed by the application of resin composite restoration , finishing and polishing
