The tensile bond strength of the inner and outer layers of two-layered acrylic resin denture teeth to heat cured and self-curing acrylic resin denture base material was tested. The bond between the heat-cured resin and the inner layer of the denture teeth was significantly stronger than the bond between the heat-cured resin and the outer layer of the denture teeth. The bond between both layers of the denture teeth and the self-curing acrylic resin was significantly weaker than with the heat-cured acrylic resin. In situations where excessive reduction of the teeth is required there may be a case for choosing teeth with a homogenous structure.

Department of Pharmaceutical Sciences, School of Pharmacy, Shanghai University of Traditional Chinese Medicine, Shanghai 201203, China.
Background: Hot-melt Pressure-sensitive Adhesives (HMPSA) are eco-friendly pressuresensitive adhesives, with the potential of being used as substrates for transdermal patches. However, due to the low hydrophilicity of HMPSA, the application is limited in the field of Traditional Chinese Medicine (TCM) plasters.
Methods: Three modified HMPSA were prepared with acrylic resin EPO, acrylic resin RL100, and Polyvinylpyrrolidone (PVP) as the modifying materials.
Not All Antiseptic Solutions Are Equivalent in Removing Biofilm: A Comparison Across Different Orthopaedic Surfaces.

Adult Reconstruction and Joint Replacement, Hospital for Special Surgery, New York, NY.
Background: Antiseptic solutions are commonly utilized during total joint arthroplasty (TJA) to prevent and treat periprosthetic joint infection (PJI). The purpose of this study was to investigate which antiseptic solution is most effective against methicillin-sensitive Staphylococcus aureus (MSSA) and Escherichia coli biofilms established in vitro on orthopaedic surfaces commonly utilized in total knee arthroplasty: cobalt-chromium (CC), oxidized zirconium (OxZr), and polymethylmethacrylate (PMMA).
Methods: MSSA and E.

Osteoporotic vertebral compression fractures (OVCFs) can be painful. Percutaneous kyphoplasty (PKP) aims at strengthening the vertebra and reducing pain, but efficacy can vary among patients. The purpose of this study was to establish a risk prediction model for pain relief following PKP in patients with OVCF.

Objective: To evaluate the influence of different cleaning methods, surface treatments, and aging on the repair bond strength to a CAD/CAM glass-ceramic.
Materials And Methods: Forty-eight lithium disilicate CAD/CAM ceramic blocks were fabricated, sintered, and embedded in acrylic resin. After contamination with human saliva, they were divided according to the factors "Cleaning method" (Control-water/air spray, Air-particle abrasion with AlO, Ivoclean cleaning paste), "Surface treatment" (5% Hydrofluoric acid-HF + Silane, Monobond Etch & Prime-MEP), and "Aging" (thermocycling, no thermocycling).
