FLUID DYNAMICS ANALYSIS OF SHEAR STRESS ON NERVE ENDINGS IN DENTINAL MICROTUBULE: A QUANTITATIVE INTERPRETATION OF HYDRODYNAMIC THEORY FOR DENTAL PAIN

, 2011
Noxious thermal and/or mechanical stimuli applied to dentine can cause fluid flow in dentinal microtubules (DMTs). The fluid flow induces shear stress (SS) on intradental nerve endings and may excite pulpal mechanoreceptors to generate dental pain ...

Modification of dentin surface to enamel-like structure: A potential strategy for improving dentin bonding durability, desensitizing and self-repairing

Dental Hypotheses, 2014
Introduction: Current theories of dentin bonding are based on the concept of "hybrid layer". However, the histological complexity of dentin, as well as the vulnerability of the hybrid layer, goes against the long-term effect of dentin bonding.

Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Interpretation of the concepts of dentinal tubule and dentinal canaliculus [PDF]

The 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.

Cellular porosity in dentin exhibits complex network characteristics with spatio-temporal fluctuations.

PLoS ONE
According to the current hydrodynamic theory, teeth sensitivity is mediated by odontoblast cell processes which can be activated by fluid flow in the pericellular space of bulk dentin.

Effects of Bleaching Protocols on the Esthetic Outcome and Surface Integrity of Enamel Treated With an Ammonia‐Free Silver Fluoride Solution

Journal of Esthetic and Restorative Dentistry, Volume 38, Issue 9, Page 1754-1765, September 2026.
ABSTRACT Objective To investigate the effects of three bleaching protocols on the color stability and surface roughness of enamel previously treated with a water‐based, ammonia‐free silver fluoride solution (Riva Star Aqua). Materials and Methods Eighty‐eight human enamel/dentin specimens were demineralized and treated with Riva Star Aqua, divided into

The Role of Ion Channels in Dentine Hypersensitivity

Dentistry Review
OBJECTIVES: Dentin hypersensitivity (DH) is a common condition caused by exposure of dentinal tubules to the oral environment. This results in sharp pain in response to mechanical, thermal, chemical, and osmotic stimuli.This review examined the roles of ...
