Clinical evaluation of two "packable" posterior composite resins: two-year results
Tóm tắt
The purpose of this study was to evaluate the clinical performance of two "packable" posterior composites: Prodigy Condensable/Optibond Solo—Kerr (PC-OS) and Definite/Etch & Prime—Degussa (D-EP). Thirty-six patients participated in this study. A total of 78 restorations (40 with D-EP and 38 with PC-OS) were made. Each patient received at least two restorations (one of each studied material). The materials were handled according to the manufacturer's instructions. The occlusal adjustments were made at the placement visit. The restorations were finished and polished after 1 week. They were evaluated at baseline, and after 1 year and 2 years by two independent evaluators using the USPHS criteria. Colored slides were made of all the restorations. After 2 years, 34 patients and 74 restorations (38 with D-EP and 36 with PC-OS) were available for evaluation. A total of 50% of PC-OS restorations received A criterion and 50% received B criterion (2.8% color, 11.1% marginal staining, 27.8% superficial staining, 2.8% anatomic form and 5.6% marginal adaptation). For D-EP, 60.5% of restorations received A criterion and 39.5% received B criterion (2.6% color, 5.3% marginal staining, 10.5% superficial staining, 7.9% anatomic form and 13.2% marginal adaptation). The C criterion was observed only for marginal adaptation with D-EP (2 restorations—5.3%). The obtained data were tabulated and statistically analyzed using the Fisher, Chi-square and McNemar tests. After 2 years, PC-OS showed a significant increase in superficial and marginal staining. For D-EP the marginal adaptation and superficial staining became significantly worse than baseline.
