Assessment of the Mouth01:26

Assessment of the Mouth

1.5K
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.

Fixation and Sectioning01:03

Fixation and Sectioning

8.9K
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Area of Science:

  • Dental Science
  • Biomedical Engineering
  • Gerontology

Background:

  • Evaluating chewing efficiency is crucial, particularly for elderly and dysphagic individuals.
  • Traditional methods for assessing chewing function can be subjective and time-consuming.
  • Objective, quantifiable methods are needed for precise chewing efficiency assessment.

Purpose of the Study:

  • To evaluate three distinct two-colored chewing gums for their color-mixing ability.
  • To validate a novel, custom-built software, ViewGum©, for opto-electronic analysis.
  • To assess the reliability and discriminative capacity of ViewGum© in different participant groups.

Main Methods:

  • Two groups participated: dentate individuals and edentulous patients with implant overdentures.
  • Participants chewed three types of two-colored gum for varying cycle counts (5-50).
  • Chewing efficiency was assessed visually (Scale A) and opto-electronically using ViewGum© (Variance of Hue - VOH).

Main Results:

  • High intra- and inter-rater agreement (95.00-98.75%) was achieved at 20 chewing cycles.
  • Gums exhibited distinct color-mixing patterns (logarithmic for gum1, linear for gum2/gum3).
  • The number of chewing cycles was predictable from VOH (p<0.0001); both methods differentiated dental status.

Conclusions:

  • ViewGum© is a reliable and discriminative tool for opto-electronically assessing chewing efficiency.
  • Optimal assessment is achieved with elastic specimens chewed for 20 cycles.
  • This method is recommended for clinical and research settings, aiding in the evaluation of oro-functional status.
