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.
背景 牙胶是根管充填最常用的充填材料。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易于去除。由于氯仿、二甲苯和橙油能在最短时间内有效溶解和去除最多的牙胶，因此它们是最常用的溶剂。目的 旨在评估和比较牙胶在三种不同有机溶剂（即橙油、二甲苯和氯仿）中的溶解度。方法和材料 选取40颗拔除的单根管下颌第二前磨牙。样本分为对照组、橙油组、二甲苯组和氯仿组。用K锉和旋转锉进行开髓腔预备、清洁和成形，随后进行充填。在充填根管的开口处滴两滴指定的溶剂，并用盖茨钻针去除冠部牙胶。在去除牙胶前后拍摄锥形束计算机断层扫描（CBCT）图像，并评估溶剂的效果。统计分析 用于分析的统计检验是单因素方差分析（ANOVA）。该检验的置信区间和p值分别设定为95%和<0.05。结果 发现橙油组（第二组）去除的牙胶最多，其次是二甲苯组（第三组）>氯仿组（第四组）>对照组。方差分析的统计分析显示四组之间存在显著差异，p值小于0.05。此外，两两比较显示，橙油去除牙胶的量与二甲苯和氯仿有显著差异，显著性水平小于0.021,001。然而，对照组和氯仿组之间未观察到差异。结论 在本体外研究的局限性内，可以得出结论，橙油组去除的牙胶量最多。橙油去除牙胶的量与二甲苯和氯仿有显著差异，显著性水平小于0.02,001。因此，对照组和氯仿组之间未观察到差异。
