Abstract

Objective: The aim of this study was to assess the sealing abilities of two calcium hydroxide (Ca[OH] 2) pastes and two mineral trioxide aggregates (MTA) against leakage on direct pulp capping with a computerized fluid filtration (CFF) method. Materials and Methods: The 60 recently extracted sound human molar teeth were sectioned at the level of the highest pulp horn to obtain dentin discs of 0.5 ± 0.2 mm. The dentin discs were numbered and permeability measurements were done before and after the operation for the same sample. For simulating direct pulp capping, dentin discs were perforated with a standard diamond bur and restorated with four different capping materials: Dycal, Calcimol light-curing (LC), ProRoot MTA and DiaRoot BioAggregate. Fluid movement measurements were tested with a CFF method and a mean value was calculated for each specimen. Results: Calcimol LC and Dycal showed significantly higher fluid conductance values compared to other pulp capping materials (P < 0.05). There were no significant differences between ProRoot MTA and DiaRoot BioAggregate (P > 0.05). Conclusion: Within the limitations of this study, it can be concluded that using the MTA materials as a pulp-capping agent would be more efficient than Ca (OH) 2 materials with regard to pulpal microleakage.
用计算机化流体过滤仪评价直接封盖纸浆时封盖剂对泄漏的密封能力
目的:本研究的目的是评估两种氢氧化钙(Ca[OH] 2)糊剂和两种矿物三氧化物聚集体(MTA)在计算机流体过滤(CFF)方法直接盖髓时对泄漏的密封能力。材料与方法:将60颗新近拔除的健全人磨牙在最高牙髓角处进行切片,得到0.5±0.2 mm的牙本质盘。对同一样品的牙本质盘进行编号,并在术前和术后进行渗透性测量。为了模拟牙髓直接封盖,牙本质盘用标准钻石钻穿孔,并使用四种不同的封盖材料进行修复:Dycal, calcalmol光固化(LC), prooroot MTA和DiaRoot BioAggregate。流体运动测量采用CFF方法进行测试,并计算每个样品的平均值。结果:与其他盖髓材料相比,钙mol LC和Dycal的流体电导值显著高于其他盖髓材料(P < 0.05)。prooroot MTA与DiaRoot BioAggregate之间无显著差异(P > 0.05)。结论:在本研究的限制范围内,可以得出结论,MTA材料作为牙髓封盖剂比Ca (OH) 2材料在牙髓微渗漏方面更有效。
