Abstract Aim: To evaluate the clinical performance of two bulk Fill composites (Admira Fusion x-tra and Tetric N-ceram) and one incremental composite (Gandio SO) in Class I molar cavities along one year. Materials and methods: Twenty patients of age 20-35 years old selected to participate according to inclusion criteria. Each patient received at least three restorations. Restorations were randomly distributed to eliminate variables such as tooth type and position. Patients were selected from the clinic of Conservative Dentistry Department, Faculty of Dentistry, Tanta University to participate in the present study. They signed an informed consent approved by the Ethics Committee of Faculty of Dentistry of Tanta University. All the benefits, drawbacks, difficulties expectations and steps of the treatment procedures were explained in details. Each patient received three different composite resin restorations, two bulk-fills and one incremental type; (Admira Fusion x-tra bulk-fill and Futurabond U adhesive system), (Tetric N-ceram bulk-fill composite resin restoration and Tetric N bond adhesive system) and (Grandio SO composite resin and Futurabond U adhesive system). Simple Class I molar cavity was prepared according to caries extension; extension for prevention was disregarded for maximal substance protection. Cavity preparation was limited to just removal of carious lesions with the moderate cavity depth 3-4mm (cavities less than 4-5 mm will be excluded) without preparing any undercuts (no macro mechanical means of retention) and no bevels were prepared. All the cavities were prepared using number #57 straight plain carbide fissure burs. |
