Dental caries remains to be one of the most prevalent diseases encountered in the field of dentistry. Several restorative materials have been introduced with variable properties and among them, composite restorative materials are most widely used nowadays because of their superior esthetic property as well as minimal hard tissue removal. Shear bond strength of a restorative material plays a key role in deciding the restoration's longevity. Hence, for a better selection of the composite material, shear bond strength needs to be evaluated.
The study aim was to analyze the shear bond strength of three commercially available esthetic restorative composite materials-Dentsply Ceram X, 3M ESPE™ Filtek™ Z350 XT, and GC Solare Sculpt to the tooth surface.
Thirty extracted human mandibular permanent molars that were caries-free were selected and erected in acrylic blocks. The uniform dentinal surface was exposed by cutting with a diamond disk. These were then randomly divided into three groups-groups I, II, and III based on the restorative material which was used, i.e., Ceram X, 3M ESPE™ Filtek™ Z350 XT, and Solare Sculpt, respectively. The restorative materials were applied on the dentinal surface of the prepared tooth specimens with the help of plastic molds, followed up by storing them in distilled water until they were subjected to shear bond strength testing. The collected data were examined by applying a one-way analysis of variance (ANOVA) and Turkey's test.
The Ceram X (21.6155 ± 2.20717) and Solare Sculpt (19.8747 ± 3.99732) were comparable in terms of shear bond strength values; however, they depicted significantly higher bond strength compared to 3M ESPE™ Filtek™ Z350 XT (12.8068 ± 3.99732).
Among the three materials compared in this study, Ceram X produced higher shear bond strength to tooth surface when compared to Solare Sculpt and 3M ESPE™ Filtek™ Z350 XT.
Restoration failure continues to be a major problem taking a toll on the dentists' time and patient satisfaction. Thus, the demand for restorative materials with better shear bond strength as well as excellent esthetics is on the rise. Thus, this particular study compares the shear bond strength of three commercial esthetic nanocomposites.

龋齿仍然是牙科领域最常见的疾病之一。已经引入了几种具有不同特性的修复材料，其中复合修复材料由于其出色的美学性能以及对硬组织的最小去除量，如今被最广泛地使用。修复材料的剪切粘结强度在决定修复体的使用寿命方面起着关键作用。因此，为了更好地选择复合材料，需要评估其剪切粘结强度。
本研究旨在分析三种市售美学修复复合材料——登士柏西诺德Ceram X、3M ESPE™ Filtek™ Z350 XT和GC Solare Sculpt与牙齿表面的剪切粘结强度。
选择30颗无龋的拔除人类下颌恒磨牙，固定于丙烯酸树脂块中。用金刚石盘切割以暴露均匀的牙本质表面。然后根据所使用的修复材料将其随机分为三组——第一组、第二组和第三组，分别使用Ceram X、3M ESPE™ Filtek™ Z350 XT和Solare Sculpt。借助塑料模具将修复材料应用于制备好的牙齿标本的牙本质表面，随后将其储存在蒸馏水中，直至进行剪切粘结强度测试。通过应用单因素方差分析（ANOVA）和土耳其检验对收集的数据进行分析。
Ceram X（21.6155±2.20717）和Solare Sculpt（19.8747±3.99732）在剪切粘结强度值方面具有可比性；然而，它们的粘结强度明显高于3M ESPE™ Filtek™ Z350 XT（12.8068±3.99732）。
在本研究中比较的三种材料中，与Solare Sculpt和3M ESPE™ Filtek™ Z350 XT相比，Ceram X对牙齿表面产生了更高的剪切粘结强度。
修复失败仍然是一个主要问题，耗费牙医的时间并影响患者满意度。因此，对具有更好剪切粘结强度以及出色美学性能的修复材料的需求正在上升。因此，本特定研究比较了三种市售美学纳米复合材料的剪切粘结强度。
