Interfacial adaptation of newly prepared nano-tricalcium silicate-58s bioactive glass-based endodontic sealer.

Background: The sealer's interfacial adaptability is one of the critical factors for successful root canal therapy. This study evaluated and compared the interfacial adaptability of newly prepared nano-tricalcium silicate-58s bioactive glass-based endodontic sealer (C S-BG-P) to root dentin with two bioactive sealers Nishika Canal Sealer BG and BioRoot RCS.

Methods: Thirty newly extracted single-rooted lower premolars were decoronated and instrumented.

Physical-chemical properties and acellular bioactivity of newly prepared nano-tricalcium silicate-58s bioactive glass-based endodontic sealer.

Objectives: To evaluate the physiochemical properties and apatite-forming ability of a newly prepared nano-tricalcium silicate-58s bioactive glass-based endodontic sealer (CS-BG-P) and compare its results with the Nishika BG canal sealer and BioRoot™ RCS.

Methods: The physicochemical properties (setting time, flow, solubility, film thickness, and radiopacity) of CS-BG-P, Nishika BG canal sealer, and BioRoot™ RCS were evaluated in accordance with ANSI/ADA 57/2000 (reaffirmed 2012) and ISO 6876:2012 for root canal sealing materials. The in vitro apatite-forming ability was evaluated after 28 days of immersion of disc-shaped specimens in phosphate-buffered saline (PBS) using field emission scanning electron microscopy and energy-dispersive X-ray spectroscopy.

Effect of Oral Vitamin D3 on Dental Caries: An In-Vivo and In-Vitro Study.

Aim Vitamin D3 plays an important role in affecting the overall remineralization process of the dentition. The use of supplements help to keep the levels at optimum and thus reduce the chances of treating very early lesion of caries. Hence the aim was to investigate the indirect effects of oral vitamin D3 on microhardness and elemental weight percentage of Calcium (Ca) and Phosphorous (P) in enamel surface with an artificially initiated carious lesion.
