Warm vertical condensation technique showed deeper root dentin penetration of the sealer. Better adaptation of the sealer to apical root dentin with minimal voids (
≤ 0.05) was achieved with warm vertical condensation in comparison to the injectable gutta-percha method and lateral condensation obturating techniques.

At all three root levels (coronal, middle, and apical), warm vertical condensation technique exhibited more sealer penetration with minimum gaps, whereas lateral condensation technique exhibited more gaps and less sealer penetration.

The aim is to evaluate the effect of different layer thickness on the amount of elution of monomers from two high viscosity bulk-fill composites after 24 h and 1 month storage in ethanol using high-performance liquid chromatography (HPLC) analysis.

Forty-eight samples prepared from two high viscosity bulk-fill composite resins; Tetric EvoCeram Bulk Fill and x-tra fil were divided into three groups (
= 8) based on their layer thickness, i.e., Group 1 (2 mm), Group 2 (4 mm), and Group 3 (6 mm) and were then subdivided based on their storage period. The analysis of the eluates was performed using HPLC unit. Statistical analysis was performed using One-way ANOVA, independent sample
-test, and paired "t" test at a significance level of 0.05 (
< 0.05).

Increase in layer thickness resulted in increased amount of bisphenol A-glycidyl methacrylate (Bis-GMA) and urethane dimethacrylate (UDMA) elution for both composites, i.e., Group 3 > Group 2 > Group 1 and there was statistically significant difference among all the groups. Tetric EvoCeram Bulk Fill showed a statistically significant increase in amount of Bis-GMA and UDMA elution for all groups compared to x-tra fil. Furthermore, increase in storage period resulted in statistically significant increase in amount of Bis-GMA and UDMA elution for both composites, i.e., Group 1B > Group 1A, Group 2B > Group 2A, and Group 3B > Group 3A. The mean value of UDMA elution was higher when compared to that of Bis-GMA elution for both composites and there was statistically significant difference for all groups.

Within the limitations of this
study, it was concluded that increase in layer thickness resulted in increased amount of Bis-GMA and UDMA elution for both Tetric EvoCeram Bulk Fill and x-tra fil.

can be found in failed endodontic treatment (FET) even after performing primary endodontic treatment (PET). Calcium hydroxide (Ca(OH)
) cannot fully eliminate this microorganism during PET. Brazilian green propolis (bee glue) was found to be more effective against
when compared to Ca(OH)
. A much less studied Malaysian geopropolis (MP) as well as
(AV) is antibacterial but is unknown against
.

The objective of this study is to determine the antimicrobial effects of MP, AV, and MP + AV in comparison with Ca(OH)
against
, as an intracanal medicament.

Antimicrobial activity of MP, AV, MP + AV, Ca(OH)
, and dimethyl sulfoxide was tested against
using antimicrobial sensitivity testing, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC). The results were analyzed by Kruskal-Wallis test with Mann-Whitney
test and repeated measures analysis of variance with Bonferroni
test (
< 0.05).

For agar well-diffusion method, MP + AV gave maximum inhibition zone diameter (mean 8.11 ± 0.015 mm), MP (mean 6.21 ± 0.046 mm, Ca(OH)
(mean 5.5 ± 0.006), and AV (mean 5.05 ± 0.012) with
< 0.05. MIC for MP + AV was 2 mg/ml, MP at 8 mg/ml, Ca(OH)
at 8 mg/ml, and AV at 16 mg/ml. The MBC for MP + AV is at 4 mg/ml, MP at 16 mg/ml, Ca(OH)
at 16 mg/ml, and AV at 32 mg/ml.

The combination of MP and AV consistently showed better antimicrobial activity compared to MP and AV alone against
. The findings suggest that MP and AV used in combination may be an ideal intracanal medicament in FET and PET.

To assess the effect of etidronic acid (EA) mixed with sodium hypochlorite (NaOCl) and two ethylenediaminetetraacetic acid-containing preparations (EDTA and SmearClear) alternated with NaOCl, as a final rinse, on root fracture resistance to a compressive force.

Seventy-two premolar roots were randomly allocated to the following groups according to the irrigant solutions. signaling pathway For the EA group, 9% EA + 2.5% NaOCl were used throughout the assays (
= 21). The remaining groups received 2.5% NaOCl during and immediately after chemo-mechanical instrumentation. Intermediately, the roots received 17% EDTA (
= 19), or SmearClear (
= 16), or no irrigation (control) (
= 16) plus a final rinse with 2.5% NaOCl. The specimens were subjected to a vertical compressive force loaded at a crosshead speed of 0.02 mm/s parallel to the long axis of the root until fracture occurred. The results were compared statistically using the one-way analysis of variance for intergroup comparisons.

The negative control presented with the highest values, whereas the SmearClear presented with the lowest values, though no significant differences were found when comparing the different groups (
= 0.82).

The use of EA + NaOCl or two EDTA formulations in association with NaOCl does not affect the fracture resistance of previously chemo-mechanically prepared roots.

Regenerative endodontics uses the concept of tissue engineering to restore the diseased immature tooth, allowing for continued development of the root to a healthy state. For regenerative endodontics, the use of human dental pulp stem cells (HDPSCs) with appropriate scaffolds and growth factors is imperative.

The aim of the study was to evaluate the human dental pulp cell viability in two-dimensional (2D) and 3D fibrin glue scaffold to be used in regenerative endodontics.

Regenerative potential of HDPSCs was comparatively assessed usings 2D and 3D fibrin glue scaffold. 3D scaffold was made with different concentrations of fibrinogen. Cell morphology was studied under inverted phase-contrast microscopy, and cell proliferation was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay at various time intervals.

Collected data underwent a two-way ANOVA test. The
value of the study was kept 0.05 according to the sample size.

Study revealed a significant increase in the proliferation of HDPSCs in fibrin glue precoated wells of 2D fibrin glue compared to preseeded cells on day 1 and day 3.
