Deglutition01:25

Deglutition

2.3K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

Oral Cavity01:11

Oral Cavity

1.0K
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...

Assessment of the Mouth01:26

Assessment of the Mouth

328
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.

Cephalic Phase of Digestion01:24

Cephalic Phase of Digestion

1.5K
The process of digestion is composed of three stages – cephalic, gastric, and intestinal – each with a distinct control center. The cephalic phase is the first stage, and it starts even before the food enters the stomach. It is controlled by the central nervous system and is initiated by any food-related sensory stimuli, such as the sight and smell of food, which send signals to the brain. While eating, the taste receptors intensify these signals, which travel to the cerebral cortex...

Tooth Anatomy01:21

Tooth Anatomy

872
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Summary

Chewing gummy jelly revealed distinct masticatory path patterns. Normal chewing patterns demonstrated superior masticatory performance compared to abnormal patterns, with no significant sex-based differences observed.

Area of Science:

  • Oral physiology
  • Biomechanics of mastication
  • Nutritional science

Background:

  • Understanding masticatory function is crucial for assessing dietary intake and oral health.
  • Gummy jelly provides a standardized food model for studying chewing mechanics.
  • Previous research has not fully elucidated the relationship between specific masticatory path patterns and performance.

Purpose of the Study:

  • To investigate and classify masticatory path patterns during gummy jelly chewing.
  • To evaluate masticatory performance based on glucose extraction across different patterns.
  • To determine potential sex-based differences in masticatory patterns and performance.

Main Methods:

  • 235 healthy adults chewed gummy jelly for 20 seconds per side.
  • Masticatory movements were recorded using the Motion Visi-Trainer (MVT V1).
  • Masticatory performance was quantified by measuring glucose extraction.

Main Results:

  • A normal pattern (N) was the most frequent (73.6%), followed by abnormal patterns (A1-A4).
  • Pattern N was most common in both sexes, with no significant sex differences in pattern occurrence.
  • Masticatory performance, indicated by glucose extraction, was significantly higher in the normal pattern (N) compared to abnormal patterns.

Conclusions:

  • Masticatory path patterns during gummy jelly chewing are classifiable into normal and abnormal types.
  • Normal masticatory patterns are associated with significantly higher masticatory performance.
  • No significant sex differences were found in masticatory path patterns or performance with gummy jelly.
