Summary
Stronger perioral muscles, including tongue and cheek pressure, are linked to better chewing performance in healthy adults. This study found that increased muscle strength correlates with improved masticatory efficiency.
Area of Science:
- Oral physiology
- Biomechanics
- Human performance
Background:
- Masticatory performance is crucial for nutrient intake and overall health.
- The role of perioral muscle strength in mastication is not fully understood.
- Previous research has focused on jaw muscles, with less attention to perioral muscles.
Purpose of the Study:
- To investigate the association between perioral muscle strength and masticatory performance in healthy adults.
- To compare muscle strength and chewing efficiency between sexes and habitual/non-habitual chewing sides.
Main Methods:
- 56 healthy adults (30 male, 26 female) with normal occlusion participated.
- Perioral muscle pressure (tongue, cheek) measured using JMS device.
- Masticatory performance assessed by glucose extraction from gummy jelly after chewing.
Main Results:
- Men exhibited higher maximum tongue pressure, cheek pressure, and glucose extraction than women.
- Glucose extraction was significantly higher during habitual chewing (H) versus non-habitual chewing (non-H).
- Positive correlations found between perioral muscle pressure and masticatory performance in both sexes.
Conclusions:
- Higher perioral muscle pressure is associated with enhanced masticatory performance.
- Sex and chewing side influence both muscle strength and chewing efficiency.
- Findings highlight the importance of perioral muscles in effective chewing.

The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

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.

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
