“…The use of extracted human teeth sharing similar anatomy might mimic clinical set up accurately; however, recruitment of the specimens should be performed meticulously due to the high variation of isthmus type, volume, length, and dimensions. Micro‐CT enables the validation of experimental groups' homogeneity prior to experimental procedures without harming the specimens (Keleş et al, ). Isthmus dimensions were taken into consideration to create homogeneity by selecting similar specimens regarding their length, major diameters, and volume in the present study.…”

“…A recent study reported that the mean percentage of void volume was 1.4 and 2.3% at the apical 3 mm of root canals of teeth showing Vertucci Type II canal morphology and a V‐shaped isthmus, irrespective of filling techniques (Keleş et al, ). It is known that isthmus ovality is an important factor for the void distribution produced by root canal filling techniques (Çelikten et al, 2016; Keleş et al, ). Keleş et al () reported that canal filling techniques resulted in void percentages between 2.6 and 10% in the coronal half of canals, where the ovality is the most increased.…”

“…These challenges have been reported to result in voids within the canal filling and in the interface between filling and dentine (Gillen et al, ). The homogeneity of the obturation material has been assessed by the calculation of voids present within fillings performed with different materials or techniques using micro‐computed tomography (micro‐CT), which is a nondestructive method to visualize inner anatomy of teeth and canal fillings (Çelikten et al, ; Huang et al, ; Keleş et al, ; Kim, Kim, Park, Jung, & Shin, ).…”

The present micro‐computed tomography (micro‐CT) study compared the presence of voids in the band‐shaped isthmuses obturated by warm vertical compaction (WVC) and single‐cone (SC) techniques. Twenty mesial roots from mandibular first molar teeth showing a band‐shaped isthmus were selected and assigned into two groups based on their preoperative anatomical dimensions (n = 10), according to the filling technique: WVC or SC. Post‐filling micro‐CT scanning was performed. The percentage volume of root canal filling materials and voids were calculated and data were analyzed using the Mann–Whitney U test with a significance level of 5 and 95% confidence interval. Mean percentage volumes of filling materials and voids were 86.88 ± 8.53 and 13.11 ± 8.53 for the WVC group, 84.39 ± 8.30 and 15.60 ± 8.30 for the SC group, respectively, with no significant difference between them (p > .05). Neither WVC nor SC produced void‐free root canal fillings in the band‐shaped isthmuses and both techniques resulted in a similar quality of root canal filling.

“…The presence of microorganisms in these areas compromises the endodontic treatment outcome, as this is a risk factor for post-treatment apical periodontitis [ 9 ]. Therefore, the significance of a 3-dimensional (3D) sealing of the root canal system must be emphasized [ 10 ].…”

Objectives The present study aims to compare the obturation quality of 2 confluence confirmation techniques in artificial maxillary first premolars showing Vertucci type II root canal configuration. Materials and Methods Thirty artificial maxillary premolars having Vertucci type II root canal configuration were made. They were divided into 3 groups according to the confluence confirmation technique as follows. Gutta-percha indentation (GPI) group (confluence confirmation using a gutta-percha cone and a K file); electronic apex locator (EAL) group (confluence confirmation using K files and EAL); and no confluence detection (NCD) group. In the GPI group and the EAL group, shaping and obturation were performed with the modified working length (WL). In the NCD group, shaping was performed without WL adjustment and obturation was carried out with an adjusted master cone. Micro-computed tomography was used before preparation and after obturation to calculate the percentage of gutta-percha occupied volume (%GPv) and the volume increase in the apical 4 mm. Data were analyzed using 1-way analysis of variance and post hoc Tukey's test. Results Statistically significant difference was not found in terms of the %GPv from the apex to apical 4 mm. However, the NCD group showed a statistically significant volume increase compared with the EAL group ( p < 0.05). Conclusions In terms of gutta-percha occupied volume, no significant difference was observed among the 3 groups. Confluence confirmation using an EAL in teeth with Vertucci type II configuration showed less volume increase during canal shaping compared with no confluence confirmation.

AimThis study aimed to use the micro‐computed tomography to evaluate the interfacial adaptation and the presence of gaps of NeoMTA Plus, BioRoot RCS, and MTA in the root‐end cavities.MethodologyThirty standardized bovine roots measuring 15 mm in length were selected. Chemical–mechanical preparation was performed up to instrument #80 and obturation with the cold lateral compaction technique with cement based on zinc oxide and eugenol. The roots were kept at 37°C for 7 days. Afterward, apicectomy of the apical 3 mm and a root‐end filling cavity was performed at 3 mm depth. Micro‐computed tomography (micro‐CT) was performed to measure the volume of the retroactivity. The roots were divided by stratified randomization into three groups according to the retro‐end filling material: NeoMTA Plus, BioRoot RCS, and MTA. A new micro‐CT was performed to assess the presence of voids in the root‐end filling material and between it and the canal wall. One‐way ANOVA and Tukey tests were performed using the BioEstat 4.0 program.ResultsThere was no difference in the initial volume values of the root‐end cavities (p > .05). After the insertion of root‐end filling materials, the most significant volumes of voids were observed in the NeoMTA Plus group (p < .05), with no difference for the BioRoot RCS and MTA Angelus groups (p > .05).ConclusionMicro‐computed tomography showed that MTA and BioRoot RCS have better interfacial adaptation and presented fewer number of gaps than NeoMTA Plus when used as root‐end filling materials.Research Highlights Micro‐computed tomography evaluation of different root‐end fillings materials.
