Title: Clinical Efficacy and Marginal Adaptation of Cavities Restored with Composite Tetric N- Ceram Bulk Fill by Two Conventional LED Devices and LED Third Generation
Abstract: Background and Objective: The aim of this study was to investigate the marginal adaptation of Ttric N-Ceram Bulk Fill Filled restorations with two curing units: conventional full name (LED) and third generation LED. Subjects and Methods: Sixty premolar teeth divided in 4 groups (n=15) Standardizes cavies prepared in one proximal Surface of teeth. Cavities restored with two posterior composites; Tetric N-Ceram Bulk Fill and photo core. Each composite cured with a conventional LED curing unit and a third generation of LED curing unit. The adhesive applied to all groups was single Bond 2. The restored ns were aged and stored in fushin. After sectioning, dye penetration was investigated under the stereomicroscope (scale -0-3*25). man Whitney and Krustal-Wallis tests were used to analyzed the data (p<0.05) Results: All groups showed dye penetration at the gingival margin of the cavities. No significant difference was found between two composites and the type of curing units. Conclusion: Posterior small to medium cavies with the depth of 4 mm can be restored with Tetric N-Ceram Bulk Full. Either conventional or third generation LED curing can be used to cure this composite.
