A Comparison of an NPG-GMA and Two BIS-GMA Adhesive Resin Systems.

摘要

Based upon the assessment of data collected from the nineteen patients in this study: (1) There was no statistically significant difference over nine months in the retention of the NPG-GMA or BIS-GMA resin systems to dentin; (2) About 70% of the restorations were present at the end of nine months; (3) The Nuva system, however, had the most favorable surface when viewed by the SEM; (4) Adaptation of the adhesive resin to a rounded cervical defect was more difficult than for an angular lesion.
