The aim of the present study is volumetric analysis of root canal filling with cold lateral compaction, Obtura II, Thermafil, and Calamus using spiral computerized tomography (SCT).
Root canals of eighty mandibular premolars were instrumented using rotary ProTaper, and the volume of the canal space was measured using spiral computerized tomography (SCT). The teeth were divided into four groups of twenty teeth each, and root canals filled by lateral compaction technique, Thermafil carriers, Obtura II, and Calamus techniques, respectively. AH Plus was used as a sealer with all techniques. The filled volume in each canal was measured using SCT, and the percentage of obturated volume (POV) was calculated. The data were statistically analyzed using ANOVA, Kruskal-Wallis test, and Mann-Whitney U-test.
The four groups were comparable in canal volume. The overall POV was 78.11%, 85.72%, 82.50%, and 87.89% for lateral compaction, Thermafil, Obtura II, and Calamus, respectively (P Conclusion: The greatest POV was obtained with Calamus and Thermafil. Voids were seen in all root fillings.
本研究旨在使用螺旋计算机断层扫描(SCT)对冷侧向加压充填、Obtura II、Thermafil和Calamus根管充填进行容积分析。
使用旋转ProTaper对80颗下颌前磨牙的根管进行预备,并使用螺旋计算机断层扫描(SCT)测量根管空间的容积。将牙齿分为四组,每组20颗,分别采用侧向加压技术、Thermafil载体、Obtura II和Calamus技术进行根管充填。所有技术均使用AH Plus作为封闭剂。使用SCT测量每个根管的充填容积,并计算充填体积百分比(POV)。使用方差分析、Kruskal-Wallis检验和Mann-Whitney U检验对数据进行统计学分析。
四组根管容积具有可比性。侧向加压、Thermafil、Obtura II和Calamus的总体POV分别为78.11%、85.72%、82.50%和87.89%(P结论:Calamus和Thermafil获得的POV最大。在所有根管充填物中均可见空隙。
