Summary
Individuals needing orthodontic treatment showed differences in masticatory performance, specifically in median particle size and broadness of particle distribution. Females with malocclusion chewed slower at 40 cycles.
Area of Science:
- Dental Science
- Biomedical Engineering
- Human Physiology
Background:
- Masticatory performance is crucial for nutrient intake and overall health.
- Orthodontic treatment needs can potentially impact chewing efficiency.
- Understanding these differences aids in treatment planning and patient outcomes.
Purpose of the Study:
- To compare masticatory performance between individuals with and without orthodontic treatment need.
- To investigate the influence of age, sex, weight, and stature on masticatory parameters.
Main Methods:
- A cohort of 120 participants (60 male, 60 female) were categorized based on orthodontic treatment need using the Index of Complexity, Outcome, and Need (ICON).
- Masticatory performance was assessed using test foods chewed over 20, 30, and 40 cycles.
- Key parameters calculated included median particle size (MPS), masticatory frequency (MF), and broadness of particle distribution (BPD).
Main Results:
- Significant differences in MPS were observed between individuals with and without orthodontic treatment need (P < .05).
- Broadness of particle distribution (BPD) showed significant differences at 40 masticatory cycles (P < .05).
- Females exhibited poorer MPS, and those needing treatment chewed significantly slower at 40 cycles.
Conclusions:
- Masticatory performance, specifically MPS and BPD, differs between individuals with and without orthodontic treatment need.
- Age, weight, and stature did not significantly influence treatment need or MPS.
- Females, particularly those with malocclusion, demonstrated slower chewing speeds at 40 cycles.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:26Assessment of the Mouth
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.
