Hypersensitivities01:30

Hypersensitivities

7.4K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

What is a Sensory System?01:31

What is a Sensory System?

101.1K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

Responses to Heat and Cold Stress

14.7K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Cold Weather Concreting01:27

Cold Weather Concreting

372
When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.
To counteract the negative impacts of cold weather, ensuring...

Sensory Modalities01:15

Sensory Modalities

3.9K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Air-entraining Agents01:27

Air-entraining Agents

268
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Area of Science:

  • Dentistry
  • Pain Research
  • Sensory Science

Background:

  • Quantifying dentin hypersensitivity (DH) presents challenges due to the need for standardized, naturalistic stimuli.
  • Accurate measurement is crucial for effective DH management and treatment evaluation.

Purpose of the Study:

  • To identify subjects with DH and longitudinally track their pain thresholds using cold air quantitative sensory testing (QST).
  • To validate a novel cold air QST method for assessing DH stability.

Main Methods:

  • Recruited subjects via an online DH questionnaire and screened them with dental air stimulation.
  • Excluded sensitizing/habituating subjects and employed a new cold air QST device.
  • Verified single-tooth DH and analyzed temperature reliability for pain detection over three weeks using intra-class correlation coefficients.

Main Results:

  • Twenty-nine subjects completed the three-week QST monitoring.
  • Demonstrated high intra-individual stability in temperature thresholds for moderate to strong pain intensity (MPI) (ICC=0.83).
  • Mean MPI temperature was -13.69°C, with significant inter-subject variability (SD ±10.04°C).

Conclusions:

  • A novel dental QST approach using cold air stimuli shows temporally stable DH perceptions over three weeks.
  • This method meets international guidelines and is recommended for valid DH intervention testing.
