Summary
Your preferred chewing side strongly correlates with your most effective chewing side. Consistently chewing on one side is as effective as alternating sides for masticatory performance.
Area of Science:
- Biomedical Engineering
- Dental Science
- Biomechanics
Background:
- Masticatory laterality, the preference for chewing on one side, is a key aspect of oral motor behavior.
- Understanding the relationship between chewing laterality and masticatory performance is crucial for assessing oral function.
Purpose of the Study:
- To investigate the association between masticatory laterality and lateral asymmetry of masticatory performance.
- To compare masticatory performance between free-style, unilateral, and alternate unilateral chewing strategies.
Main Methods:
- A cross-sectional study involving 42 young adults with natural dentition.
- Masticatory performance was assessed using silicon pieces, measuring particle size and chewing cycle duration.
- Subjects performed free-style, right unilateral, and left unilateral chewing assays with bagged and unbagged silicon.
Main Results:
- Masticatory function was comparable between bagged and unbagged silicon.
- A significant positive relationship was found between the preferred chewing side and the side exhibiting better masticatory performance.
- Unilateral chewing demonstrated equal or greater efficiency compared to free-style chewing.
Conclusions:
- A direct association exists between the preferred chewing side and the side with superior masticatory efficiency.
- Alternate unilateral mastication does not inherently offer superior masticatory performance compared to consistent unilateral chewing.

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.

Deglutition
7.5K
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...

Direct-Acting Cholinergic Agonists: Therapeutic Uses
1.9K
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren...

Types of Selection
37.5K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...
