Correlation between ultrasound velocity and densitometry in fresh and demineralized cortical bone
ClinicsOBJECTIVE: To compare ultrasound propagation velocity with densitometry in the diaphyseal compact cortical bone of whole sheep metatarsals. METHODS: The transverse ultrasound velocity and bone mineral density of 5-cm-long diaphyseal bone segments were ...

Advanced Science, EarlyView.Mechanical orthodontic treatment for malocclusion is limited by slow remodeling and risks due to poor biomechanical sensing. This study shows that static magnetic fields (SMFs) enhance mechanical sensation in periodontal ligament cells, promoting inflammation and osteoclast activity.

Palaeoproteomic Deconvolution of Physical and Genetic Collagen Mixtures
Advanced Science, EarlyView.ClassiCOL_v2 uses a novel “peptide patching” framework that treats any collagen sample as a patchwork of peptide sequences derived from phylogenetically related species. This allows the algorithm to simultaneously resolve two previously intractable problems: multi‐species samples and/or database deficiencies.

On the stiffness of demineralized dentin matrices [PDF]
Dental Materials, 2016 Resin bonding to dentin requires the use of self-etching primers or acid etching to decalcify the surface and expose a layer of collagen fibrils of the dentin matrix. Acid-etching reduces the stiffness of demineralized dentin from approximately 19 GPa-1 MPa, requiring that it floats in water to prevent it from collapsing during bonding procedures ...

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization
Advanced Science, EarlyView.Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

A Novel Kinetic Method to Measure Apparent Solubility Product of Bulk Human Enamel
Frontiers in Physiology, 2017 Introduction: Tooth enamel mineral loss is influenced by its solubility product value, which is fundamental to the understanding of de- and remineralization resulting from a carious or erosive challenge.

Laser-fluoride effect on root demineralization
, 2006 Although the individual cariostatic effects of laser and fluoride have been shown, the combined effect of CO 2 laser and fluoride on root demineralization remains uncertain and was the main aim of this study.

Advanced Science, EarlyView.Salivary citrate deficiency in early‐stage Sjögren's syndrome accompanies impaired dentin remineralization despite preserved salivary flow and mineral availability. Matched‐ion experiments reveal disrupted mineral organization and reduced dentin recovery at disease‐associated citrate levels.

Enamel Demineralization by Mouthrinses Containing Different Concentrations of Sucrose
, 1983 Intra-oral enamel demineralization tests, involving rinsing with sucrose solutions (5, 1, 0.5, or 0.3%) at varying frequencies during a 1.5-hour period, showed that demineralization was a function of the total sugar dose (frequency of rinsing times ...
