Evaluation of Revascularization in numerous Suzuki Levels regarding Ischemic Moyamoya Condition by Whole-Brain CT Perfusion.
Data were analysed by ANOVA and Tukey tests (α=0.05).

The comparison of DTS in pH groups were 8.4>7.4>9.4>6.4>5.4>4.4 (P<0.05); and in bismuth oxide groups were fine particles > medium particles > coarse particles (P<0.05). Acidic pH, negatively affected the distribution of Ca2+ and Si4+ ions, while bismuth oxide with fine particles enhanced it.

Acidic pH can decline the DTS of MTA significantly. However, reducing the particle size of bismuth oxide can increase the DTS of MTA significantly.

The bioactivities of TotalFill BC and the MTA Fillapex sealers were evaluated.

Sixty horizontal root sections were enlarged to size 5 Gates Glidden and randomly divided into six groups (n=10 in each group). In Groups 1-3, sections were filled with TFBCS, while sections in groups 4-6 were filled with MTAFS. Specimens from groups 1 and 4 were soaked in simulated body fluid (SBF) for one day, those from groups 2 and 5 for one week, and those from groups 3 and 6 for two months. All specimens were processed for scanning electron microscope (SEM) examination. Apatite precipitation on sealer and sealer-dentine interfaces was quantified using image analysis software (ImageJ). Tomivosertib datasheet Energy dispersive X-ray (EDX) was used to analyse calcium (Ca) and phosphate (P) contents of surface precipitation on which calculation of the calcium phosphate (Ca/P) ratio was based.

TFBCS samples, regardless of the duration of SBF soaking, yielded a significantly higher surface area of precipitation compared to MTAFS (P<0.05); such phigh Ca2+ ion release as reflected by the formation of apatite with a high Ca/P ratio. These bioactivity features increased over time. In comparison, the MTAFS appears to have lower and delayed bioactivity.
There are no reports in the literature on whether FGP geometry influences the bond strength of the endodontically restored tooth. This study aimed to determine the stress distribution and the pull-out bond strength of different FGP geometries, before and after chewing loads simulation.

One hundred and twenty root analogues were prepared and randomly distributed in six groups according to the post geometry. Half of the specimens were aged in water at 37 °C using a mechanical fatigue machine (84 N, 2 bar, 45°, 106 cycles, 4 Hz); while the remaining specimens were immediately submitted to the pull-out bond strength test. The specimens were tested in a universal testing machine and the bond strength in MPa was calculated. To assess the stress concentration, the finite element method was used simulating the same post geometries that were used in the in vitro test.

Two-way ANOVA (95%) showed no influence of post geometry on the bond strength (P=0.055) while fatigue cycling was statistical significant to reduce the bond strength values (P=0.000). The factors interaction was significant (P=0.019); however, TUKEY test (5%) showed no significant difference between post geometries after mechanical cycling. The tensile stress result showed critical areas in the post's cervical region regardless of the design.

The FGP geometry does not affect the root stress distribution and the long-term bond strength. However, FGP that allow a reduced cement layer thickness can improve the immediate pull-out bond strength value.

The aim of this study was to compare and evaluate the dentinal tubule penetration and adaptation of a premixed bioceramic sealer and an epoxy-resin based sealer in the three radicular thirds.

30 wide roots, with single straight canals and totally formed apexes, were endodontically prepared and divided into two groups (n=14) according to the sealer used for root canal filling AH-Plus (AHP) and Bio-C Sealer (BIOC). Two samples were left as controls. After the canals were filled, the samples were cut and viewed under Scanning Electron Microscopy by taking images to analyse the tubular penetration and adaptation of the sealers. The results were statistically analysed with the Shapiro Wilk, Levene and Mann-Whitney tests (P<0.05).

BIOC showed significantly higher penetration in dentinal tubules than AHP in the cervical, middle and apical thirds of the root canal (P<0.05) and better adaptation to the dentinal tubule walls.

Under the parameters of this study, BIOC exhibits higher penetration and better adaptation to the dentinal tubules compared to AHP.

The aim of this study was to evaluate the sensitivity and specificity of electric pulp testing (EPT) using the bridging technique in comparison to a cold test on crowned teeth.

Thirty teeth were included in this study. Only one crowned tooth from each subject was included. The adjacent teeth served as controls. The crowned teeth were tested for pulp vitality using a bridging EPT technique and cold test. Vitality was confirmed upon access based on bleeding or lack of bleeding from detected root canal systems. The data was statistically analyzed using the McNamara test (P<0.05).

The sensitivities of the cold test and bridging EPT were 87% and 66% respectively. Accuracy for cold and bridging EPT were 87% and 67% respectively. The cold test demonstrated a statistically significant higher accuracy and sensitivity than the bridging EPT. However, no significant difference was detected in the specificity between the two tests.

Both EPT and cold test should be considered as an adjunctive diagnostic tool when determining pulp status in a crowned tooth. Pulp sensitivity tests are essential but the results should be interpreted in combination with other clinical signs/symptoms.
