Evaluating the penetration efficacy of calcium silicate-based bioceramic sealers into dentinal tubules with cold lateral compaction technique using confocal laser scanning microscopy: An study.

Background: The micromechanical interlocking between dentinal walls and root canal sealer aids in achieving a three-dimensional impermeable hermetic seal. Calcium silicate-based bioceramic sealers are promising, but their comparative effectiveness in sealing dentinal tubules still needs further research.

Objective: This study evaluated the penetration efficacy of four calcium silicate-based bioceramic sealers - CeraSeal (Meta BIOMED Co.

Nano eggshell-titanium-dioxide biocomposite in occluding opened dentine tubules.

It is of interest to synthesize Nano eggshell-titanium-dioxide (EB@TiO2) biocomposite and to evaluate its effectiveness in occluding opened dentine tubules. EB@TiO2 was synthesized and characterized using X-ray diffraction (XRD), and Transmission Electron Microscope (TEM). Sixteen simulated bovine dentine discs were prepared and randomly assigned into four groups according to the following treatment (n = 4): Group 1: No treatment; Group 2: eggshell powder; Group 3: EB@TiO2; and Group 4: GIC mousse.

Evaluation of Bond Strength of Resin and Non-resin Cements to Different Alloys.

Background:  A strong metal-cement bond is one of the many factors that contribute to the clinical success of a fixed prosthesis. Even though it is crucial to create ideal resistance and retention forms during tooth preparation, dental cement must be strong enough to hold the restoration in place in the mouth. The present study set out to evaluate and compare the binding strength of resin modified glass ionomer cement, resin cement, and glass ionomer cement to four different metal alloys: titanium alloy, cobalt-chromium (Co-Cr) alloy, nickel-chromium (Ni-Cr) alloy, and noble metal alloys (silver palladium based).

The effect of natural reducing agents on push-out bond strength of AH plus and BioRoot RCS to sodium hypochlorite treated root dentin.

Aims: To evaluate the effect of natural anticoagulants 6.5% proanthocyanidin (PA) and 25% bamboo salt on push-out bond strength (PBS) of AH Plus and BioRoot RCS to dentin.

Subjects And Methods: 30 single-rooted extracted human teeth were collected.
