“…The samples were placed in an ultrasonic device (Eruonda, Italy) for three minutes to remove the debris and be prepared for microscopic evaluations. The samples were immersed in 17% EDTA (Biomed, South Korea) for 2 minutes, followed by immersion in 5.25% NaOCl for 3 minutes and rinsing with distilled water (15). Finally, the samples were dehydrated and mounted in an aluminum stub and gold-sputtered (Fig.…”

Introduction: A sealer’s ability to effectively and stably penetrate the dentinal tubules is an essential factor for selecting an effective root canal obturation material. Evaluation of the sealers’ penetration into the dentinal tubules provides valuable data in the endodontic treatment outcome. Aim: To compare the dentin penetration of AH Plus, Endoseal MTA, and Syntex endodontic sealers in the presence and absence of the smear layer. Materials and methods: Thirty single-rooted teeth were selected in the present in vitro study and randomly assigned to three experimental groups (n=10). Half of the samples were prepared by removing the smear layer in each group, and the remaining samples were prepared without removing the smear layer. Root canal preparation was carried out with the Perfect Rotary system up to file T3. The root canals were obturated with gutta-percha and AH Plus, Endoseal MTA, or Syntex endodontic sealers. The samples were incubated at 100% relative humidity at 37°C for one week. Each root was sectioned at 2-, 5-, and 8-mm distances from the apex, and sealer penetration depth at each section was determined under a scanning electron microscope (SEM). ANOVA was used to compare penetration depths. Results: There were significant differences in sealer penetration between the samples with and without smear layer removal in each group. The maximum and minimum sealer penetration was at the coronal and apical sections, respectively. The maximum sealer penetration depths in descending order were observed with AH Plus, Syntex, and Endoseal MTA sealers (p<0.05). Conclusions: Elimination of smear layer increased three sealers’ dentin penetration depth, with the deepest penetration for the AH Plus sealer in the coronal section without the smear layer.

Background: The failure of root canal treatment is non-hermetic obturation. It could be prevented with the use of sealer material. The sealer with an excellent bond to the dentin is epoxy resin and glass ionomer cement sealer. Eucalyptus oil is a natural substance that could dissolve gutta-percha because it has an antimicrobial effect and is biocompatible. Objective: To determine the effect of softening with Cajuput Oil on root canal filling with epoxy resin and glass ionomer cement sealers. Methods: The design of this study was pure laboratory experimental, 24 samples of single root canal block, each block was prepared with step back technique and obturation with lateral condensation. The samples were treated differently by the type of sealer used and incubation time. Group of treatment will be dripped with 0.1 ml of cajuput oil for 5 minutes. Compressive loading was performed apico-coronally by Universal testing machine using cylindrical stainless-steel plunger speed of 2 mm/min until softening occurred. The data were processed using a one-way ANOVA and Post-Hoc Tukey test with a significance level of 95% (p <0,05). Results: There was a significant effect of epoxy bisphenol resin sealer and Glass Ionomer Cement sealer in softening gutta-percha using cajuput oil. The epoxy resin sealer, which was incubated for 22 days after contact with cajuput oil for 5 minutes, had a higher softening value than others. Conclusion: Sealer epoxy bisphenol resin is easier to remove than the Glass Ionomer Cement sealer with cajuput oil solvent at 22 days after incubation.
