CLINICAL EVALUATION of N'DURANCE, A HIGH-CONVERSION/LOW€-SHRINKAGE NANOHYBRID DENTAL COMPOSITE

Objective: To evaluate an 18-month clinical effectiveness of the new nanohybrid resin composite, N'DURANCE (Septodont, USA), in Class III, IV, V, diastema closure restoration and facial veneers. Materials and Methods: IRB protocol and consent approval were obtained. 52 restorations of N'DURANCE were placed using Opti-Bond Solo Total Etch (Kerr) as a dental adhesive. At the 18-month recall, 33 restorations were evaluated using a modified CDA evaluation criterion for the following variables: Anatomic Form (AF), Color Match (CM), Marginal Adaptation (MA), Marginal Discoloration (MD), Surface Staining (SS), Retention (RT), Secondary Caries (SC), Fracture (FX) and Polishability (PL). The gingival health and post operative sensitivity of the restored teeth were also evaluated. Results: Results at 18-month evaluation indicated that all restorations (33) had excellent AF, MD, SS, RT, and SC. The following results are in percentages (%).

In general, all the restorations were judged to be clinically satisfactory. CONCLUSIONS: Based on the18-month findings of this study, the High Conversion / Low Shrinkage Nanohybrid Composite, N'DURANCE, when used with Opti-Bond Solo gives excellent clinical results for anterior restorations.
