1. Prime and Bond ® NT ™ & TPH ® 3, Class I, II, IV, Facial Veneers, & Diastema Closures Material: Prime and Bond NT with TPH3 Title: A Clinical Evaluation of a New Anterior Composite Study (TPH3) Principle Investigator: Dr. James Dunn Type of Restoration: Class I, II, IV, facial veneers, and diastema closures 18 Month Results: 18 Patients; 33 Restorations; (% alpha— highest rating): Retention (97%), Sentsitivity (100%), Anatomic Form (100%), Color Match (75%), Marginal Adaptation (97%), Marginal Discoloration (100%), Surface Staining (100%), Secondary Caries (100%) Summary: The 18 month evaluation results indicated that all restorations evaluated had excellent surface stain rating, high retention, and no secondary caries. The color match was unchanged from baseline (Note: limited shades were available at placement, resulting in lower color match results). Based on the findings of this study, the “TPH3” micro- hybrid composite is a good choice for anterior or posterior restorations. 33 restorations, 18 month results

The color match remained the same over the evaluation period. All restorations were found to be clinically acceptable. 27 restorations, 3-year results

4. Prime and Bond ® NT ™ & Esthet-X ® Flow Class I Material: Prime and Bond ® NT™ and Esthet-X ® Flow Title: Clinical evaluation of three flowable composite resins in occlusal cavity preparations. Principle Investigator: Drs. John O. Burgess Type of Restorations: Class I 1-year Results: Esthet-X Flow: 21 Patients, 30 Restorations (% alpha—highest rating): Retention rate (100%), Anatomic Form (100%), Color Match (97%), Marginal Adaptation (83%), Marginal Discoloration (97%), Polish (80%), and Secondary Caries (100%). Tetric Flow: 21 Patients, 29 Restorations (% alpha—highest rating): Retention rate (100%), Anatomic Form (100%), Color Match (86%), Marginal Adaptation (62%), Marginal Discoloration (86%), Polish (79%), and Secondary Caries (100%). Summary: The purpose of this study was to compare the performance of different flowable restoratives in Class I cavities over a 1-year period—specifically, Esthet-X Flow and Tetric Flow (Ivoclar). The study allowed for correlation within subjects due to the design (multiple treatments per subject and/or multiple teeth per patient). Summary (Con’t): After 1 year, it was evident that the marginal discoloration showed a significant deterioration for Tetric Flow, which decreased from 100% Alpha to 86.2% Alpha, while Esthet-X Flow experienced no change over this time period. As regards marginal adaptation, Tetric Flow restorations decreased about 30% over 1 year, while the Esthet-X Flow restorations only decreased about 7% for the same time period. The wear for both products over the 1 year time period was approximately 20 microns. The Esthet-X Flow handled well with good, in fact surprising, clinical results.
