Abstract

Purpose: To investigate shear bond strength (SBS) of three restorative materials on primary dentin after silver diamine fluoride (SDF) application.
Methods: Thirty primary teeth were randomized into three groups of 10 teeth. Each tooth was split mesiodistally and randomized into experimental (artificial caries plus SDF) and control (sound dentine without SDF) groups. Glass ionomer cement (GIC), resin-modified bioactive resin (ACTIVA), and composite resin (CR) restorations were tested for SBS and mode of failure (MF).
Results: All SDF groups exhibited significantly lower SBS compared to the control (CR: P =0.001; ACTIVA: P =0.001; GIC: P =0.004). For the SDF group, the compa- rison of materials was statistically significant (P =0.006); posthoc tests showed significance only between CR and ACTIVA (P =0.009) and between ACTIVA and GIC (P =0.020). The lowest mean value was obtained for ACTIVA (1.4 MPa) and the highest mean value was obtained for CR (3.3 MPa). For the control group, Welch's F test was statistically significant (P =0.044), but all posthoc tests were not. For MF, SDF exhibited a significantly greater percentage of adhesive failures with ACTIVA and CR than with GIC. In the control group, a mixed MF was more dominant with no significant differences.
Conclusion : The SDF group had significantly lower SBS.

氟化二胺银处理后不同修复材料与乳牙本质的剪切结合强度

目的:研究三种氟化二胺银(SDF)修复材料在初级牙本质上的剪切结合强度(SBS)。方法:30颗乳牙随机分为3组，每组10颗。每颗牙中向裂牙，随机分为实验组(人工龋齿加SDF组)和对照组(健全牙本质不加SDF组)。玻璃离子水泥(GIC)、树脂改性生物活性树脂(ACTIVA)和复合树脂(CR)修复体的SBS和失效模式(MF)进行了测试。结果:与对照组相比，所有SDF组的SBS均显著降低(CR: P =0.001;Activa: p =0.001;Gic: p =0.004)。SDF组材料比较有统计学意义(P =0.006);术后检测仅显示CR与ACTIVA (P =0.009)、ACTIVA与GIC (P =0.020)之间存在显著性差异。ACTIVA的平均值最低(1.4 MPa)， CR的平均值最高(3.3 MPa)。对于对照组，Welch’s F检验具有统计学意义(P =0.044)，但所有事后检验均无统计学意义。对于MF, SDF与ACTIVA和CR的粘合失败率明显高于GIC。在对照组中，混合型MF更占优势，差异无统计学意义。结论:SDF组患者SBS明显降低。

期刊介绍： Acquired after the merger between the American Society of Dentistry for Children and the American Academy of Pediatric Dentistry in 2002, the Journal of Dentistry for Children (JDC) is an internationally renowned journal whose publishing dates back to 1934. Published three times a year, JDC promotes the practice, education and research specifically related to the specialty of pediatric dentistry. It covers a wide range of topics related to the clinical care of children, from clinical techniques of daily importance to the practitioner, to studies on child behavior and growth and development. JDC also provides information on the physical, psychological and emotional conditions of children as they relate to and affect their dental health.
