The primary function of dental cement is to seal and support prosthodontic restorative materials. Proper selection of the dental cement contributes to the clinical success of the restoration.
A total of 166 molar tooth samples were prepared to simulate the type of tooth commonly found in prosthodontic practice. Each sample was restored using one of the tested dental cement materials employing a prestabilized methodology. The performance of resin-modified glass ionomer cement (RMGIC) (GC Fuji PLUS Capsule, GC America, Alsip, IL), zinc phosphate cement (ZPC) (Dentsply Sirona, Charlotte, NC), and resin cement (RC) (RelyX ARC, 3M ESPE, Saint Paul, MN) in bonding strength, marginal adaptation, and microleakage was evaluated and compared. The bonding strength, marginal adaptation, and microgroove were tested using specific established methodologies. The outcomes were then analyzed using statistical analyses for means and standard deviations to compare different types of dental cement.
The total outcome shows that the highest bonding strength with the highest mean was the resin cement, rating 24.8 MPa, followed by RMGIC and ZPC at 20.5 and 18.9 MPa, respectively. The marginal adaptation scores indicate that RC had the highest score at a mean of 4, followed by ZPC at 3.2 and RMGIC at 2.5. The dye penetration measurements in millimeters revealed that ZPC had a penetration of 0.31 mm, RMGIC had a penetration of 0.25 mm, and RC had the least penetration at 0.20 mm. The results of the statistical data analysis show significant differences between the dental cements in bonding strength and marginal adaptation.
In conclusion, resin cement demonstrated superior performance in bonding strength, marginal adaptation, and resistance to microleakage compared to RMGIC and zinc phosphate cement. These findings highlight the importance of selecting resin cement for achieving optimal clinical outcomes in prosthodontic restorations.
牙科粘固剂的主要功能是封闭和支持口腔修复材料。正确选择牙科粘固剂有助于修复体的临床成功。
制备了166颗磨牙样本，以模拟口腔修复实践中常见的牙齿类型。每个样本使用一种经过测试的牙科粘固剂材料，采用预稳定方法进行修复。评估并比较了树脂改性玻璃离子水门汀（RMGIC）（GC Fuji PLUS胶囊，GC America，阿尔西普，伊利诺伊州）、磷酸锌水门汀（ZPC）（登士柏西诺德，夏洛特，北卡罗来纳州）和树脂水门汀（RC）（RelyX ARC，3M ESPE，圣保罗，明尼苏达州）在粘结强度、边缘适应性和微渗漏方面的性能。使用特定的既定方法测试粘结强度、边缘适应性和微沟。然后使用均值和标准差的统计分析来分析结果，以比较不同类型牙科粘固剂。
总体结果表明，粘结强度最高且均值最高的是树脂水门汀，评分为24.8MPa，其次是RMGIC和ZPC，分别为20.5MPa和18.9MPa。边缘适应性评分表明，RC的平均分最高，为4分，其次是ZPC，为3.2分，RMGIC为2.5分。以毫米为单位的染料渗透测量显示，ZPC的渗透为0.31mm，RMGIC的渗透为0.25mm，RC的渗透最少，为0.20mm。统计数据分析结果表明，牙科粘固剂在粘结强度和边缘适应性方面存在显著差异。
总之，与RMGIC和磷酸锌水门汀相比，树脂水门汀在粘结强度、边缘适应性和抗微渗漏方面表现出卓越的性能。这些发现凸显了选择树脂水门汀以实现口腔修复最佳临床效果的重要性。
