Insight into the Internal Structure of Biogenic, Synthetic and Geological Apatite by Electron Microscopy and X‐Ray Scattering

Advanced Functional Materials, EarlyView.
Apatite occurs in many forms in nature, e.g. in teeth and geological minerals. Internally, biological apatite contains nanocrystals that are also found in synthetically prepared calcium phosphate nanoparticles which are used in biomedicine, e.g. for gene and drug delivery and for bone regeneration. Abstract Calcium phosphate is the inorganic component (

An in vitro comparison between two methods of electrical resistance measurement for occlusal caries detection [PDF]

, 2006
Because of different measurement techniques and the easier design of the CRM prototype, this in vitro study aimed to compare the diagnostic performance and reproducibility of two electrical methods (Electronic Caries Monitor III, ECM and Cariometer 800 ...

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

Advanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Clinical efficacy of toothpaste containing potassium citrate in treating dentin hypersensitivity

Journal of Dental Sciences, 2009
Many adults suffer from sensitivity, and dentin hypersensitivity is most commonly the result of exposed dentin which can sometimes trigger pain or discomfort when eating, drinking or simply brushing. The purpose of this study was to evaluate the clinical

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

Advanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Effects of different desensitizing treatments on root dentin permeability

Brazilian Oral Research
The objective of this study was to evaluate the effects of diode laser and a desensitizing dentifrice on dentin permeability. Fifty-two root dentin fragments were obtained (5 × 5mm) and treated with 24% EDTA gel. The samples were divided into 4 groups (n

Dynamic, Reconfigurable, and Hierarchical Biosynthetic Composites via Collagen Self‐Assembly within Highly Crowded Microgel Pastes

Advanced Materials, EarlyView.
A new approach to extracellular matrix‐mimetic, hierarchical biomaterials is presented. Soft gels composed of overpacked hydrogel microparticle arrays present a biomolecularly crowded environment permissive to the self‐assembly of collagen networks.

Efficacy of a bioactive material and nanostructured desensitizing on dentin hypersensitivity treatment

Revista de Odontologia da UNESP
Introduction Dentin hypersensitivity is a frequent occurrence in dental practice. It is clinically characterized by acute, short, and temporary pain in response to mechanical, chemical, thermal, or osmotic stimuli resulting from dentin exposure ...
