This article has dentinal fluid cited by other articles in PMC. Abstract Dental thermal pain is a significant health problem in daily life and dentistry.

There is a long-standing question regarding the phenomenon that cold stimulation evokes sharper and more dentinal fluid pain sensations than hot stimulation. This phenomenon, however, outlives the well-known hydrodynamic theory used to explain dental thermal pain dentinal fluid.

Dentinal fluid | definition of dentinal fluid by Medical dictionary

Here, we present a mathematical model based on the hypothesis that hot or cold stimulation-induced different directions of dentinal fluid flow and the corresponding odontoblast movements in dentinal microtubules contribute to different dental pain responses.

We coupled a computational fluid dynamics model, describing the fluid mechanics in dentinal microtubules, dentinal fluid a modified Hodgkin-Huxley model, describing the discharge behavior of intradental neuron.

The outward flow repels acids and microbes, keeping them from penetrating the tooth. The fluid, being alkaline, helps neutralize acids generated by the microbes. So if teeth are protected, why do they become vulnerable to decay? Because sometimes, the flow can actually reverse course or otherwise be disrupted.

When dentinal fluid flows inward, toward the pulp, it draws acids dentinal fluid pathogens into the tooth, as well.

Factors that can reverse or disrupt the flow include high intake of sugars and simple carbs, inactivity, chronic stress, pharmaceutical drug dentinal fluid and malnutrition not getting enough vitamins, minerals and other necessary micronutrients.

Suffice it to say, healthful dentinal fluid and an active, balanced lifestyle are among the best things you can do to make sure your teeth can take care of themselves as they were designed to do.


The others, of course, are regular flossing and brushing. Nutritionally, you want to be sure to get plenty of calcium, phosphorous and vitamin Dall of which help remineralize dentinal fluid teeth, keeping them strong and solid.

Also, a healthy intake of antioxidants may reduce inflammation, which subsequent research has shown capable of interfering with good hypothalamus function — the gland Dr.

Steinman and his colleague Dr. Cavities were prepared dentinal fluid human premolars scheduled for extraction for orthodontic reasons. The smear layer was removed from the dentin surface by acid etching, and the cavity was sealed dentinal fluid a hollow chamber.

The chamber was filled with sterile saline solution and connected via tubing to a hydraulic circuit featuring an adjustable pressure reservoir and dentinal fluid device that measures fluid movement across dentin.
