title: Clinical evaluation of two "packable" posterior composite resins.
abstract: The purpose of this study was to evaluate the clinical performance of two "packable" posterior composites: Prodigy Condensable (P) (Kerr) and Definite (D) (Degussa). Thirty-six patients participated in the study. A total of 78 restorations were made, 40 with D and 38 with P. Each patient received at least two restorations, one of each studied material. The materials were handled according to the manufacturer's instructions. The restorations were finished and polished after 1 week. They were evaluated at baseline and after 1 year by two independent evaluators using the United States Public Health Service (USPHS) criteria. Colored slides were made of all the restorations. After 1 year, 35 patients and 76 restorations (39 with D and 37 with P) were available for evaluation. All restorations received A criteria except the following ones, which received B criteria: color P (one restoration) and D (one restoration), marginal staining P (three restorations) and D (two restorations), surface staining P (nine restorations) and D (three restorations), anatomic form P (one restoration) and D (three restorations), and marginal adaptation P (one restoration) and D (eight restorations). The obtained data were tabulated and statistically analyzed using the Fisher and McNemar tests. After 1 year, P showed a significant increase in superficial staining. For D, the marginal adaptation became significantly worse than baseline and P. The studied materials can be considered acceptable during this evaluation period. Further evaluations are necessary for a better clinical performance analysis.
