Class I and II posterior composite resin (Ful-Fil) restorations were placed and were clinically evaluated, according to the US Public Health Service criteria, at baseline, 6 months, 5 years, and 8 years. At 5 years/8 years, alpha scores were assigned to the following percentages of restorations: 16%/31% for color match; 65%/62% for marginal discoloration; 74%/54% for cavosurface marginal discoloration; 100%/100% for axial contour; and 81%/65% for anatomic form. At 5 years/8 years, 56%/33% of Class II restorations had tight proximal contacts; 45%/44% had light contacts; and 0%/22% had no contacts. Transient postoperative sensitivity was reported in 6% of the restorations. Indirect evaluation indicated that there was an average of 64 +/- 35 microns of wear at baseline (because of overfinishing), 105 +/- 67 microns at 6 months, 217 +/- 76 microns at 5 years, and 253 +/- 82 microns at 8 years. At 5 years, three of the restorations, and at 8 years, four additional restorations, were clinically unacceptable because of recurrent caries and/or excessive wear. Final success rates of 90% and 77% at 5 and 8 years, respectively, were calculated.
I类和II类后牙复合树脂（Ful-Fil）修复体被放置好，并根据美国公共卫生服务标准在基线、6个月、5年和8年进行临床评估。在5年/8年时，对修复体的以下百分比给出了alpha评分：颜色匹配为16%/31%；边缘变色为65%/62%；洞缘边缘变色为74%/54%；轴面外形为100%/100%；解剖形态为81%/65%。在5年/8年时，56%/33%的II类修复体有紧密的邻面接触；45%/44%有轻度接触；0%/22%没有接触。6%的修复体报告有短暂的术后敏感。间接评估表明，基线时平均磨损64±35微米（由于过度打磨），6个月时为105±67微米，5年时为217±76微米，8年时为253±82微米。在5年时，有3个修复体，在8年时，又有4个修复体，因继发龋和/或过度磨损而在临床上不能接受。分别计算出5年和8年的最终成功率为90%和77%。
