Advanced Theory and Simulations, EarlyView.The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

Thermal irritation of teeth during dental treatment procedures
Restorative Dentistry & Endodontics, 2013 While it is reasonably well known that certain dental procedures increase the temperature of the tooth's surface, of greater interest is their potential damaging effect on the pulp and tooth-supporting tissues.

Stress behaviour across human tooth by temperature gradient resulting of laser irradiation
Journal of Mechanical Engineering and Sciences, 2020 The authors report the simulation of temperature distribution and thermally induced stress in the premolar tooth under ND-YAG pulsed laser beam. The Three-Phase-Lag (TPL) non-Fourier model is proposed to describe the heat conduction in the human tooth ...

Intra-pulp temperature increase of equine cheek teeth during treatment with motorized grinding systems : influence of grinding head position and rotational speed [PDF]
, 2014 BACKGROUND: In equine practice, teeth corrections by means of motorized grinding systems are standard procedure. The heat resulting from that treatment may cause irreparable damage to the dental pulp. It has been shown that a 5.5degreesC temperature rise

Advanced Science, EarlyView.Early childhood caries (ECC) involves cariogenic persisters that evade antimicrobial treatment. Persisters achieve this by downregulating heat shock proteins (HSPs) and formation of protein aggregates. Ti3C2 MXene‐based photothermal therapy (PTT) acts as a “nanothermal knife,” disrupting membranes, upregulating HSPs, inhibits aggregates, prevents ...

Microenvironment Influences Odontogenic Mesenchymal Stem Cells Mediated Dental Pulp Regeneration
Frontiers in Physiology, 2021 Dental pulp as a source of nutrition for the whole tooth is vulnerable to trauma and bacterial invasion, which causes irreversible pulpitis and pulp necrosis. Dental pulp regeneration is a valuable method of restoring the viability of the dental pulp and

Advanced Science, EarlyView.The Irisin/Ce‐MBGNs delivery system can slowly release myokine Irisin for vital pulp therapy. Irisin/Ce‐MBGNs can enhance mitochondrial function and promote the differentiation of inflammatory macrophages toward M2‐Mφ, thereby regulating the immune response mechanism of inflamed dental pulp.
