Evaluation of osteoblast response to polyacrylonitrile infused nano-curcumin coated on titanium discs: Invitro study cell culture experimental study.

Purpose: The study evaluated the influence of titanium discs, coated with polyacrylonitrile infused curcumin nanofibers on osteoblast activity.

Materials And Methods: The titanium discs were coated with polyacrylonitrile nanofibers infused with curcumin. MG-63 cell lines were utilized for cell culture to assess osteoblast morphology upon exposure of curcumin on titanium discs.

Effect of curcumin on physico-mechanical properties of heat polymerized denture base resin.

Purpose: Current denture base resins lack adequate strength and antimicrobial properties, necessitating the exploration of alternative solutions. The purpose of this study was to evaluate the effects of curcumin incorporation on the physico-mechanical properties of heat-cured denture base resin, filling a gap in the literature regarding this correlation.

Methods: Heat-cured denture base resin was supplemented with increasing concentrations of curcumin (CR).

Comparing the influence of cuspal angulation, occlusal loading, and connector widths between tooth- and implant-supported zirconia fixed dental prosthesis.

Background: Few studies have established the relationship between connector widths, cuspal angulation, loading forces, and supporting structures of zirconia fixed dental prosthesis (FDP). The objective of the study was to compare the stress distribution in implant- and tooth-supported zirconia FDP with different connector designs, and cuspal angulations of replaced teeth under diverse angulations of forces.

Methods: Finite element (FE) analysis was done by simulating a 3-unit implant- and tooth-supported FDP.

Trends and future perspectives of 3D printing in prosthodontics.

The three-dimensional (3D) printing technology has led to transformative shift in prosthodontics. This review summarizes the evolution, processing techniques, materials, integration of digital plan, challenges, clinical applications and future directions of 3D printing in prosthodontics. It appraises from the launch of 3D printing to its current applications in prosthodontics.

A review of Health Canada's progress on human biomonitoring-based risk assessments and the path forward.

Since the launch of the Chemicals Management Plan (CMP) in 2006, Health Canada has initiated screening-level risk assessments (RAs) of approximately 4300 priority substances under the Canadian Environmental Protection Act, 1999 (CEPA). With the availability of nationally representative human biomonitoring (HBM) data, over 300 of these substances were assessed using HBM-based RA approaches. Qualitative and quantitative HBM-based RA approaches for the regulatory risk assessment of the general population of Canada were developed to increase the efficiency of screening the potential health risk of CMP priority substances.
