背景Gutta-percha是用于根管闭塞的最常用的填充材料。这种热塑性材料满足根管充填的主要要求,其中之一是在牙髓再治疗的情况下容易去除的材料。最常用的溶剂是氯仿,二甲苯,和橙色油,因为它们在最短的时间内溶解和去除最大的古塔胶。目的评估和比较古塔胶在三种不同有机溶剂中的溶解度,即,橙色油,二甲苯,还有氯仿.方法和材料选择40颗单管拔除的下颌第二前磨牙。样本被归类为对照,橙色油,二甲苯,还有氯仿.通过k文件和旋转文件进行清洁和成型的访问腔准备,其次是闭塞。将两滴指定的溶剂放在闭塞管的孔上,电晕-古塔-胶胶被盖茨滑翔钻清除。锥束计算机断层扫描(CBCT)图像拍摄之前和之后的古塔胶去除,和溶剂的效力进行了评估。统计分析用于分析的统计检验是单向方差分析(ANOVA)。该测试的置信区间和p值分别设定为95%和<0.05。结果发现,橙色油(II组),其次是二甲苯(III组)>氯仿(IV组)>对照组,对胶胶的去除量最大。通过ANOVA的统计学分析揭示了四组之间的显著差异,p值小于0.05。此外,配对比较表明,用橙色油去除古塔胶的量与二甲苯和氯仿明显不同,显著性水平小于0.021,001。然而,对照组和氯仿之间没有观察到差异。结论在本体外研究的局限性内,可以得出结论,在橙色油组中发现了最大量的古塔胶去除量。用橙色油去除古塔胶的量与二甲苯和氯仿明显不同,显著性水平小于0.02,001。因此,在对照组和氯仿组之间没有观察到差异。
Background Gutta-percha is the most frequently used filling material for root canal obturation. This thermoplastic material fulfills the primary requisites for root canal filling, one of which is easily removable material in cases of endodontic retreatment. The most commonly used solvents were chloroform,
xylene, and orange oil due to their effectiveness in dissolving and removing maximum gutta-percha in a minimum time. Aims The aim is to evaluate and compare the solubility of gutta-percha in three different organic solvents, i.e., orange oil, xylene, and chloroform. Methods and material Forty extracted mandibular second premolars with a single canal were selected. The sample was categorized into control, orange oil,
xylene, and chloroform. Access cavity preparations with cleaning and shaping were performed by k files and rotary files, followed by obturation. Two drops of assigned solvent were placed on the orifices of the obturated canal, and corona-gutta-percha ha was removed by gates glidden drills. Cone-beam computed tomography (CBCT) images were taken before and after the gutta-percha removal, and the solvents\' efficacy was assessed. Statistical analysis The statistical test applied for the analysis was one-way analysis of variance (ANOVA). The confidence interval and p-value were set for this test at 95% and < 0.05, respectively. Results Gutta-percha Removal was found to be maximum with orange oil (Group II) followed by
xylene (Group III) >Chloroform (Group IV) >Control Group. The Statistical Analysis by ANOVA revealed a significant difference between the four groups with a p-value of less than 0.05. Furthermore, the pair-wise comparison revealed that the amount of gutta-percha removal with orange oil significantly differs from xylene and chloroform, with a significance level of less than 0.021,001. However, there was no difference observed between control and chloroform. Conclusions Within the limitations of this in vitro
study, it can be concluded that the maximum amount of gutta-percha removal was found in the orange oil group. The amount of gutta-percha removal with orange oil significantly differs from
xylene and chloroform, with a significance level of less than 0.02,001. Hence there was no difference observed between Control and Chloroform groups.
