Abstract：
To evaluate the impact of using ion-releasing liners on the 3-year clinical performance of posterior resin composite restorations after selective caries excavation with polymer burs. 20 patients were enrolled in this trial. Each patient had two deep carious lesions, one on each side of the mouth. After selective caries removal using polymer bur (PolyBur P1, Komet, Brasseler GmbH Co. KG, Lemgo, Germany), cavities were lined with bioactive ionic resin composite (Activa Bioactive Base/Liner, Pulpdent, Watertown, MA, USA) or resin-modified glass ionomer liner (Riva Light Cure, SDI, Bayswater, Victoria, Australia). All cavities were then restored with nanofilled resin composite (Filtek Z350XT, 3M Oral Care, St. Paul, MN, USA). All the tested materials were placed according to the manufacturers\' instructions. Clinical evaluation was accomplished using World Dental Federation (FDI) criteria at baseline and after 6 months, 1, 2, and 3 years. Data were analyzed using Mann-whitney U and Friedman tests (p < 0.05). The success rates were 100% for all resin composite restorations either lined with ion-releasing resin composite or resin-modified glass ionomer liner. Mann-whitney U test revealed that there were no statistically significant differences between both ion-releasing lining material groups for all criteria during the follow-up periods (p > 0.05). Resin composite restorations showed acceptable clinical performance over 3 years either lined with bioactive ionic or resin-modified glass ionomer liners after selective caries excavation preserving pulp vitality. After the 3-year follow-up period, Activa Bioactive and Riva Light Cure liners were clinically effective and they exhibited with the overlying composite restorations successful clinical performance.Trial registration number: NCT05470959.

摘要：
评估使用离子释放衬垫对聚合物毛刺选择性龋齿挖除后树脂复合材料修复体3年临床性能的影响。20名患者被纳入本试验。每个病人都有两个深龋病变,嘴的每一侧都有一个。在使用聚合物bur（PolyBurP1，Komet，BrasselerGmbHCo.KG,Lemgo,德国),空腔衬有生物活性离子树脂复合材料(ActivaBioactiveBase/Liner，牙髓,沃特敦,MA,美国)或树脂改性玻璃离聚物衬里(RivaLightCure，SDI,贝斯沃特,维多利亚,澳大利亚)。然后用纳米填充树脂复合材料(FiltekZ350XT，3M口腔护理,圣保罗,MN,美国）。根据制造商的说明放置所有测试材料。在基线和6个月后，使用世界牙科联合会（FDI）标准完成临床评估。1、2、3年。使用Mann-whitneyU和Friedman检验分析数据(p<0.05)。所有衬有离子释放树脂复合材料或树脂改性玻璃离聚物衬里的树脂复合材料修复体的成功率均为100％。Mann-whitneyU检验显示，在随访期间，对于所有标准，两个离子释放衬里材料组之间没有统计学上的显着差异（p>0.05）。在选择性龋齿挖掘后，树脂复合材料修复体在3年内显示出可接受的临床性能，无论是用生物活性离子衬里还是用树脂改性的玻璃离聚物衬里。经过3年的随访，ActivaBiactive和RivaLightCure衬垫在临床上有效，并且与上覆的复合修复体一起表现出成功的临床性能。试验注册号：NCT05470959。注册日期：2022-7-22。追溯登记。
