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.
