TWO-YEAR CLINICAL EVALUATION OF SMART DENTIN REPLACEMENT FLOWABLE RESIN COMPOSITE AS A LINER UNDER CLASS II RESIN COMPOSITE RESTORATIONS
Mohammed Ali Salem, Mohammed Awad, Nashaat Magdy

Objectives: To evaluate in Vivo the effect of Smart Dentin Replacement (SDR) resin-based composite as a liner under  Class II nano hybrid resin composite restorations after two years. Methods: Forty-five patients with Class II carious lesions were selected. A total of 90 Class II cavities were prepared in premolar/molar teeth. The cavities were equally divided into  three groups. Group I was restored with nanohybrid RBC (Esthet.x-HD), group II was restored with Esthet.x-HD/SurFil SDR flowable composite and group III was restored with Esthet.x-HD/Filtek z350 XT flowable composite. The patients were recalled at 6,12 and 24 month and restorations were evaluated using Modified United States Public Health Criteria (USPHS criteria). Results: There were no significant differences (p >0.05) between the tested groups. Conclusions: SDR as 4 mm bulk fill dentin replacement showed good performance as a liner under nano hybrid composite resin restorations.
