Abstract

Background: The complex anatomy of root canals in primary teeth makes root canal treatment and canal filling difficult. Root canal filling materials should meet the basic requirements for hermetic filling in terms of their physicochemical properties, such as radiopacity and viscosity, which might be affected by heat.

Objectives: The aim of this study was to investigate the effect of different temperatures on the filling quality and hermetic obturation ability of primary root canal filling pastes.

Materials and methods: Primary root canal filling pastes containing calcium hydroxide with barium sulphate and calcium hydroxide with iodoform were heated to four different temperatures (4°C, 23°C, 39°C and 55°C). After instrumentation, 80 endodontic blocks were filled with the heat-treated sealers. Digital radiographs were taken and analysed. The results were analyzed using Tukey's HSD, two-way Robust ANOVA, and the Bonferroni test for multiple comparisons.

Results: The results of this study, the obturation radiopacity values of calcium hydroxide paste containing barium sulphate showed significant differences at different temperature values. Paste at 4°C showed significantly higher radiopacity (p<0.001). Paste at 55°C showed both significantly higher radiopacity (p<0.001), and the total unfilled area values obtained at 55°C was found to be significantly lower than the other temperatures (p=0.025).

Conclusion: It was observed that the preheating process had a positive effect both on the filling quality and hermetic obturation capacity of primary root canal sealants at high temperatures.

根管充填容量及根管膏质量的评价。
背景:由于乳牙根管结构复杂,使得根管治疗和根管充填困难。根管充填材料的物理化学性质,如不透光性、黏性等,都应满足密闭式充填的基本要求。目的:研究不同温度对根管充填膏体充填质量和封闭性能的影响。材料和方法:将含有氢氧化钙-硫酸钡和氢氧化钙-碘仿的初级根管填充糊加热至4℃、23℃、39℃和55℃四种不同温度。预备完成后,用热处理过的密封剂填充80个根管块。拍摄并分析了数字射线照片。结果采用Tukey’s HSD、双向稳健方差分析和Bonferroni多重比较检验进行分析。结果:本研究结果显示,含硫酸钡的氢氧化钙膏体在不同温度值下的闭孔透光度值有显著差异。结论:高温预处理对根管密封胶的充填质量和封闭能力均有积极的影响。
