“…The present study used SEM to observe the obturated surface area which was congruent with the previous studies 1, [3][4][5]8 because of the ability to produce high resolution images and higher magnification compared with the conventional microscope. This approach is appropriate for evaluating the irregular surfaces due to the depth of the focal field and the degree of magnification obtainable.…”

“…The obturation quality has been studied by many researchers in aspects of the presence of marginal gaps and voids. [1][2][3][4][5][6][7][8][9] Marginal gaps are defined as a discontinuity at the interface made of two different materials while voids are defined as the vacant area surrounded by the same materials. 5 During obturation procedure, the extrusion of root filling material beyond the apical foramen is sometimes inevitable, especially in patent root canal terminus.…”

INTRODUCTION: This study compared the obturated surface area, the extrusion of root filling material beyond the apical foramen and the duration of obturation procedure in single-rooted mandibular premolar using monocone obturation technique. MATERIALS AND METHODS: The root canal of twenty single-rooted mandibular premolars were prepared, and then divided into two groups; Group 1 (GuttaFlow Bioseal (GFB) and a gutta-percha (GP) cone) and Group 2 (RoekoSeal Automix root canal sealer and a GP cone). The obturation procedure was timed and the obturation radiograph was taken after the procedure. The roots were sectioned perpendicularly and the surfaces were observed under scanning electron microscope. The images were transferred to the SketchAndCalc Area Calculator software for evaluation of the obturated surface area. RESULTS: The median score of obturated surface area in Group 1 and 2 at the apical was 86.51 and 83.00, at the middle was 90.48 and 87.35 and at the coronal was 93.00 and 83.39, respectively. The extrusion of root filling material between two groups did not show statistically significant difference. The mean duration of obturation in Group 1 and 2 was 149.50 and 137.60, respectively. CONCLUSIONS: The obturated surface area at the apical and middle root regions in Group 1 and 2 was comparable but at the coronal region, Group 1 showed 11.5% better coverage. The extrusion of root filling material in Group 1 and 2 was equivalent. Obturation procedure in Group 1 took 8.6% longer than in the Group 2.

“…Moreover, this method allows for the distinction of gutta-percha, sealer, and tooth structure volumes at different levels of the dental roots (apical, middle, and coronal thirds) due to the possibility of using different greyscale levels [ 20 ]. Given these advantages, studies investigating endodontic filling quality using micro-CT analysis have become relatively frequent [ 21 – 24 ]. Still, selected segmentation threshold values may vary largely, and the objects of interest may vary along with the different settings used [ 25 ].…”

While several materials and techniques have been used to assess the quality of root canal fillings in micro-CT images, the lack of standardization in scanning protocols has produced conflicting results. Hence, the aim of this study was to determine a cutoff voxel size value for the assessment of root canal filling voids in micro-CT and nano-CT images. Twenty freshly extracted mandibular central incisors were used. Root canals were prepared with nickel titanium files to an ISO size 40/0.06 taper and then filled with a single cone (40/0.06 taper) and AH Plus sealer. The teeth were scanned with different voxel sizes with either micro-CT (5.2, 8.1, 11.2, and 16.73 μm) or nano-CT (1.5 and 5.0 μm) equipment. Images were reconstructed and analyzed with the NRecon and CTAn software. Void proportion and void volume were calculated for each tooth in the apical, middle, and coronal thirds of the root canal. Kruskal-Wallis and post hoc Mann–Whitney U tests were performed with a significance level of 5%. In micro-CT images, significantly different results were detected among the tested voxel sizes for void proportion and void volume, whereas no such differences were found in nano-CT images (p > 0.05). Micro-CT images showed higher void numbers over the entire root length, with statistically significant differences between the voxel size of 16.73 μm and the other sizes (p < 0.05). The values of the different nano-CT voxel sizes did not significantly differ from those of the micro-CT (5.2, 8.1, and 11.2 μm), except for the voxel size of 16.73 μm (p < 0.05). All tested voxel sizes enabled the detection of root canal filling voids except for the voxel size of 16.73 μm. Bearing in mind the limitations of this study, it seems that a voxel size of 11.2 μm can be used as a reliable cutoff value for the assessment of root canal filling voids in micro-CT imaging.

Aim:To study the prevalence of additional root canal orifices of upper first permanent molars in Saudi subpopulation in Jeddah, Kingdom of Saudi Arabia, utilizing micro-computed tomography X-ray (micro-CT). Materials and methods:One hundred extracted upper first permanent molars of Saudi patients were included in the study. Micro-CT was used to detect the prevalence of extra root canal orifices of the permanent upper first molars. Results:The evaluation of three-dimensional (3D) images of this study showed that of 100 upper permanent first molars scanned and analyzed, 10.53% had 6 pulp canal orifices, 35.09% had 5 pulp canal orifices, 47.37% had 4 pulp canal orifices and 7.01% had 3 pulp canal orifices. Conclusion:The current data showed the highest prevalence of 4 and 5 root canal orifices compared to 3 and 6 root canal orifices. Clinical significance:The knowledge of anatomic variations of teeth before starting root canal treatment can help dentists to detect and manage all root canals successfully.
