Summary
The number of occlusal units is a key predictor of masticatory performance. This study used bicolored chewing gum to assess mixing ability and found that more teeth significantly improve chewing function.
Area of Science:
- Dental Science
- Biomedical Engineering
- Oral Health Research
Background:
- Limited studies explore predictors of masticatory performance using mixing ability tests.
- Assessing chewing function is crucial for overall health and nutrition.
Purpose of the Study:
- To identify determinants of masticatory performance.
- To evaluate masticatory ability using bicolored chewing gum and quantitative methods.
Main Methods:
- Recruited 137 non-dental participants aged 18+.
- Used bicolored chewing gum (20 strokes) analyzed via Photoshop (standard method) and Chewing Performance Calculator.
- Collected sociodemographic, behavioral, medical, and oral health data.
Main Results:
- Masticatory performance was higher in younger individuals, those with greater salivary flow, non-denture users, and more occlusal units.
- Multiple regression identified the number of occlusal units as the sole significant predictor.
- Each occlusal unit improved masticatory performance by 0.8% to 2.2%.
Conclusions:
- The number of occlusal units is a primary predictor of masticatory performance.
- Bicolored chewing gum mixing ability tests are effective for assessing chewing function.

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.

Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to...
