Assessment of the Mouth01:26

Assessment of the Mouth

1.6K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Oral Cavity01:11

Oral Cavity

3.8K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

3.6K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Area of Science:

  • Biomaterials Science
  • Dental Materials
  • Tribology

Background:

  • Mimicking the complex oral environment in vitro is crucial for testing dental materials.
  • Existing simulators may not fully replicate the combined chemical and mechanical challenges faced by dental structures.

Purpose of the Study:

  • To introduce and describe the novel Rub&Roll simulator.
  • To demonstrate its capability in simulating oral conditions for wear and fatigue testing.

Main Methods:

  • The Rub&Roll device utilizes counter-rotating cylinders to apply controlled force, speed, and liquid conditions.
  • Specimens are subjected to various simulated oral challenges, including acidic slurry, fruit juice/pulp, and abrasive conditions.

Main Results:

  • The simulator allows for precise control over force, speed, liquid type, and duration.
  • Tested applications included occlusal wear, erosive-abrasive wear, sealant wear, and adhesive bond strength under mechanical loading.
  • Results obtained were clinically relevant, reproducible, and consistent with existing literature.

Conclusions:

  • The Rub&Roll simulator effectively replicates in vivo oral conditions.
  • It enables controlled application of combined chemical and mechanical loading for diverse dental research applications.
