(1) The latest one-step self-etch systems showed significant higher bond strengths than earlier one-step systems. However, even the latest systems could not eliminate technique sensitivity.(2) Class 5 resin composites restored with two-step self-etch (Liner Bond 2) and two-step total-etch (Single Bond) systems have demonstrated excellent clinical performances for 9 years.(3) Although marginal discoloration occurred earlier compared to the two-step systems, class 5 resin composite restored with the latest one-step self etch systems (S^3 Bond and G-Bond) have shown acceptable clinical performances for 18 months.(4) There were no significant difference in clinical performances between types of resin composite (hybrid : Clearfil AP-X ; flowable Clearfil Flow FX).(5) Significant difference in 10-year survival rates of class 5 resin composites was found between operators (principal investigator:86%, other dentists:54%).(6) Loss of restorations was the main reason for failures of class 5 resin composites. From the viewpoint of tooth types, however, their main reasons were different: secondary caries for anterior teeth and loss for posterior teeth.(7) Mean progress rate of non-carious cervical lesions was approximately 70 μm per year.(8) Caries at cervical regions has been arrested for 5.8 years if it was in non-active stage.(9) A questionnaire study on decision-making for retreatment of resin composites revealed that there were great variances in criteria among dentists in some cases.(10) Long-term clinical observation suggested that monitoring of restorations could provide more accurate diagnosis and proper decision-making.

(1)最新的一步自蚀刻系统显示出显着更高的粘结强度比早期的一步系统。然而，即使是最新的系统也无法消除技术敏感性。(2)使用两步自蚀刻（Liner Bond 2）和两步全蚀刻（Single Bond）系统修复的5类树脂复合材料已在9年内表现出优异的临床性能。(3)尽管与两步系统相比，边缘变色发生得更早，但使用最新的一步自蚀刻系统（S^3 Bond和G-Bond）修复的5类树脂复合材料在18个月内表现出可接受的临床性能。(4)不同类型树脂复合材料（混合型：Clearfil AP-X ;可流动型Clearfil Flow FX）的临床性能无显著差异。(5)5级树脂复合材料的10年生存率在不同术者之间存在显著差异（主要研究者：86%，其他牙医：54%）。(6)结晶度损失是5类树脂复合材料失效的主要原因。但从牙型上看，其主要原因是不同的：前牙继发龋和后牙缺失。(7)非龋性宫颈病变的平均进展速度约为每年70 μm。(8)颈部龋处于非活动期者，其防龋期为5.8年。(9)一项关于树脂复合材料再治疗决策的问卷调查显示，在某些情况下，牙医之间的标准存在很大差异。(10)长期的临床观察表明，监测并发症可以提供更准确的诊断和正确的决策。
