“…It provides a high-resolution image, and 3D visualization of the images allows the inspection of the internal structure as well. In addition, it requires less time and is less labor intensive [35,[46][47][48][49][50][51][52][53][54][55][56][57][58]. Therefore, the micro-CT analysis was considered suitable for observing and quantifying the internal and external porosity from the canal space separately.…”

This study aimed to quantify and compare the obturation quality after mineral trioxide aggregate (MTA) orthograde fillings with three different obturation techniques. Thirty-three extracted human maxillary molars were collected. Distobuccal and palatal canals were prepared to an apical size of #40/06 with a Profile Ni-Ti system. All 66 canals were divided into two groups according to the material (EZ-seal or OrthoMTA) and then obturated using three different techniques: manual compaction using S-kondenser (group H), compactor activation (group C), or reverse rotary motion of Ni-Ti file (group R). The obturated roots were scanned using micro-computed tomography (micro-CT). The percentage of voids located in the apical 5 mm was measured separately, that is, closed, open, and total porosity. There was no relation between the filling material and obturation technique (p > 0.05). The percentage volume of open and total porosity was higher in EZ-seal than in OrthoMTA (open: p = 0.002, total: p = 0.001). Group H showed higher open and total porosity than groups C and R. Micro-CT analysis showed that the void volume after orthograde MTA fillings significantly decreased when the additional activation was accompanied by hand condensation. Obturation with a Ni-Ti file using reverse motion could be recommended as an MTA orthograde filling technique.

“…Therefore, given the effect of each porosity and its clinical outcome, it is important to distinguish the location of the porosity. It seems rational to focus more on open porosity, which may contribute to apical periodontitis [50,53,54].…”

“…Milanovic et al wanted to quantify and compare the closed and open porosity of calcium silicate-based cements (BioRoot RCS, EndoSequence BC Sealer, MTA Fillapex) with epoxy resin-based cements (AH plus), and evaluate the long-term effect of conservation within simulated body fluids on porosity; higher percentages of open porosity than closed porosity were recorded in all samples [31]. Significantly higher open and total porosities were initially found in MTA Fillapex than AH Plus.…”

In recent years, calcium silicate cements have been introduced. The purpose of this study is to analyze the main differences between calcium silicate-based cements and epoxy resin-based cements, analyzing the scientific literature of the last year to highlight the main advantages for predictable clinical use. Data collected from the included studies were used in order to analyze different features: chemical-physical properties, cytotoxicity and cell migration, inflammatory response, mineralizing and osteogenic activity, ion release and the filling efficiency of root canals. The calcium silicate cements analyzed in these studies showed good biological and mechanical properties compared to conventional resin-based cements, resulting in better biocompatibility and less cytotoxicity; long-term studies are needed, but these cements have ideal characteristics to allow efficient filling of root canals.

“…The two types of pores can be detected: open or external, and closed or internal [5]. The open pores form between the filling material and the root-canal walls and therefore create a through-and-through "network" of the pores providing the excellent conditions for the microleakage and negatively affecting the outcome of endodontic treatment [2,6]. Meanwhile, the internal pores are entrapped inside filling material and do not have any substantial adverse clinical impact [5].…”

“…Microcomputed tomographic (µCT) imaging has recently become the technique of choice to assess the quality of root-canal cleaning, shaping, and obturation in vitro [14,27]. The technique ensures the possibility of characterizing filling materials, and quantifying and qualifying the pores, voids, and gaps inside the material or at the material/root-canal wall interface [5,6]. The main advantage of the µCT method is its nondestructiveness, repeatability, and high accuracy [17].…”

The objective of this study was to assess the porosity distribution of BioRoot RCS/single gutta-percha point root-canal fillings performed by a general dental practitioner and endodontist. Fourteen plastic models of maxillary premolars with two roots were selected and shaped with HyFlex EDM instruments to a size 40/0.04 taper and randomly divided into two experimental groups. A total of 14 canals in each group were obturated by two different operators with one HyFlex EDM size 40 gutta-percha point and BioRoot RCS sealer. The specimens were scanned with a high-resolution micro-computed tomography scanner, and the porosity of the fillings at the coronal, middle, and apical thirds of the root canals was qualified and quantified. The differences between groups and root-canal thirds were compared using Mann–Whitney, Friedman, and Wilcoxon tests with the significance level set at p < 0.05. The highest number of pores was observed in the apical third of root-canal fillings in both groups; however, the porosity distribution between the two groups was not significantly different in the apical and middle thirds (p > 0.05). Statistically significant differences were determined only in the coronal third (p < 0.05). The predominance of open pores was detected in all root-canal thirds and groups, with no significant differences in the number of open pores between the coronal and middle thirds (p > 0.05).
