Cention N is relatively new and an "alkasite" restorative material, indicated for direct restorations.
The aim of this study was to comparatively evaluate the sealing ability of Cention N and resin-modified glass ionomer cement (GIC) when used to restore primary molars.
It is a split-mouth study. Twenty children having bilateral deep dentinal caries involving primary molars requiring restoration were selected. After caries excavation under the rubber dam, samples were collected from the cavity. Restorations of the teeth were done using either resin-modified GIC (RMGIC) or Cention N. Patients were recalled after 6 weeks and the restorations done previously were removed using contra angled micromotor handpiece under rubber dam isolation. The samples were collected again. The collected samples were used to estimate the total viable count.
The pretreatment, posttreatment colony counts, and the differences between the groups were analyzed using paired -test.
No statistically significant difference was observed in the mean differences of the pre- and posttreatment colony count between alkasite restorative material and RMGIC ( = 0.056).
Restorations done using alkasite restorative material and RMGIC performed equally in terms of sealing ability.
Cention N是一种相对新型的“碱式材料”修复材料,适用于直接修复。
本研究的目的是比较评估Cention N和树脂改性玻璃离子水门汀(GIC)用于修复乳磨牙时的封闭能力。
这是一项双侧对照研究。选取20名患有双侧涉及需要修复的乳磨牙的深龋患儿。在橡皮障下进行龋洞预备后,从窝洞中采集样本。使用树脂改性GIC(RMGIC)或Cention N对牙齿进行修复。6周后召回患者,在橡皮障隔离下使用反角微型电机机头去除先前进行的修复体。再次采集样本。采集的样本用于估计活菌总数。
使用配对t检验分析治疗前、治疗后菌落计数以及组间差异。
碱式修复材料与RMGIC治疗前和治疗后菌落计数的平均差异无统计学显著差异(P = 0.056)。
使用碱式修复材料和RMGIC进行的修复在封闭能力方面表现相当。
