Nanomaterials, 2019 Dentin hypersensitivity (DH) is one of the most common clinical conditions usually associated with exposed dentinal surfaces. In this study, we identified the effectiveness of poly(amidoamine) (PAMAM) dendrimer-coated mesoporous bioactive glass ...

Measure of the hygroscopic expansion of human dentin [PDF]
arXiv, 2022 Background: Direct dental restoration implies a drying of the dentin substrate. This drying may induce significant strain in the dentin, affecting the bonding efficiency of the restoration. Objective: We measure the dilatation of dentine under changes of relative humidity as well as the impact of humidity on dentin elastic properties. This investigates

Phases and Transitions in Phantom Nematic Elastomer Membranes [PDF]
Phys. Rev. E 71, 011802 (2005), 2004 Motivated by recently discovered unusual properties of bulk nematic elastomers, we study a phase diagram of liquid-crystalline polymerized phantom membranes, focusing on in-plane nematic order. We predict that such membranes should enerically exhibit five phases, distinguished by their conformational and in-plane orientational properties, namely ...

Anomalous elasticity in nematic and smectic elastomer tubule [PDF]
Phys. Rev. E 78, 031704 (2008), 2008 We study anomalous elasticity in the tubule phases of nematic and smectic elastomer membranes, which are flat in one direction and crumpled in another. These phases share the same macroscopic symmetry properties including spontaneously-broken in-plane isotropy and hence belong to the same universality class.

Membrane tubulation by elongated and patchy nanoparticles [PDF]
Adv. Mater. Interfaces 2016, 1600325, 2016 Advances in nanotechnology lead to an increasing interest in how nanoparticles interact with biomembranes. Nanoparticles are wrapped spontaneously by biomembranes if the adhesive interactions between the particles and membranes compensate for the cost of membrane bending.

Self-assembly of Chiral Tubules [PDF]
Soft Matter 10, 510 (2014), 2013 The efficient and controlled assembly of complex structures from macromolecular building blocks is a critical open question in both biological systems and nanoscience. Using molecular dynamics simulations we study the self-assembly of tubular structures from model macromolecular monomers with multiple binding sites on their surfaces [Cheng et al., Soft

Interpretation of the concepts of dentinal tubule and dentinal canaliculus
Regulatory Mechanisms in BiosystemsThe biology of dentin occupies a central place in the theory of tooth integrity as an organ, and knowledge about the microstructure of dentin changes with the development of new research methods, such as scanning electron microscopy.

Evaluation of the Efficacy of Caries Removal Using Polymer Bur, Stainless Steel Bur, Carisolv, Papacarie – An Invitro Comparative Study [PDF]
Journal of Clinical and Diagnostic Research, 2015 Context: Dental caries continues to affect a significant portion of the world population and treatment of the decay is associated with pain by many patients. Intervention and application of rotary instruments for treatment of carious lesions has often
