Masticatory path pattern and masticatory performance while chewing gummy jelly

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.
