“…3 Similar results were recorded using chloroform with PTUR as the results showed that chloroform presented the highest value for remaining root canal filling when used as a solvent. 13 However, the results of the present study came in contradiction with other studies in which there was no difference in the capacity between these three solvents. 1,9,14 This could be attributed to the different evaluation methods as they used immersion weight loss evaluation, while in this study a more clinical method using solvents and rotary files till reaching the working length.…”

ObjectivesThe aim of the study was evaluation of the effectiveness of three different solvents (orange oil solvent, eucalyptol oil solvent, and chloroform) during retreatment regarding: root canal filling removal Methods were 33 premolar root canals were prepared by using Protaper universal files for cleaning and shaping, obturation was done by lateral compaction technique. Samples were divided (n=11) Group A Chloroform, Group B orange oil, and Group C Eucalyptus oil according to the solvent used into three groups. Retreatment was done by combining two methods for filling removal as chemical by using organic solvents and mechanical by utilizing rotary retreatment files (Protaper retreatment files). Roots were split longitudinally, canals were observed using a stereomicroscope at 6x. The images were subjected to morphometric analysis to assess the amount of remaining root filling materials. Data were explored for normality using Kolmogorov-Smirnov and Shapiro-Wilk tests, data showed parametric (normal) distribution. Repeated measure ANOVA was used to compare between more than two groups in related samples. Results:The highest mean value was found in (Group A) followed by (Group B), while the least mean value was found in (Group C). A statistically significant difference was found between (Group C) and each of (Group A) and (Group B) (p<0.001). No statistically significant difference was found between (Group A) and (Group B) (p=0.853). Conclusion:Chloroform and orange oil are preferable to be used in retreatment.

“…It compared two sealers with or without chloroform using maxillary incisor with straight root. The study contradicted Sherif et al's study (12) because this study exhibited that using chloroform left less filling material than without chloroform and BC sealer showed more remnants obturated material than AH Plus. Furthermore, this study supported the finding of Hess et al in 2011 that AH Plus could regain 100% patency and BC sealer could gain patency when used solvent and no solvent 93% and 14% respectively (11).…”

“…There was the study about using solvent or no solvent (chloroform) on the retreatment of BC sealer by using SEM. The result showed that removal filling material using solvent left more residual filling material than rotary instrument alone (12). Recently, there was one study on retreatability between BC sealer and AH Plus by using micro-computed tomography.…”

This study evaluated�the influence of a curved root canal on the retreatment efficacy of root canals sealed with bioceramic sealer. 60 mandibular molars were divided into 4 subgroups of severely curved canal filled with AH Plus, slightly curved canal filled with AH Plus, severely curved canal filled with BioRoot RCS�and slightly curved canal filled with BioRoot. Two�weeks after root canal obturation, retreatment�was performed with WaveOne Gold Primary and ProTaper Next X3 following with passive ultrasonic irrigation. The retreatment efficacy parameters were regaining canal patency, retreatment time and residual filling material. MicroCT and confocal microscope were used to evaluate the residual filling materials and sealer penetration in dentinal tubules. Regaining canal patency was compared by Pearson Chi-square test. Retreatment time and residual filling materials were compared using one-way ANOVA at 0.05 level of confidence. �Retreatment efficacy of BioRoot RCS in severely curved root canal was similar�to that of slightly curved root canal. There was no significant difference in retreatment efficacy between BioRoot RCS and AH Plus groups, except for regaining canal patency.
