Summary
This study investigated preferred chewing side (PCS) determination in 60 subjects. While two methods showed no significant agreement, both indicated a strong tendency for a right-sided chewing preference.
Area of Science:
- Dentistry
- Human Physiology
- Biomechanics
Background:
- Lateral preference is common in human activities, including hand use.
- Mastication, or chewing, also exhibits a preferred chewing side (PCS), though its determination is complex.
Purpose of the Study:
- To analyze the relationship between two different methods for determining a lateral chewing preference.
- To investigate the consistency of preferred chewing side determination.
Main Methods:
- Analysis of mastication in 60 healthy subjects.
- Utilized preferred chewing side (PCS) tests, the Kazazoglu test, and kinesiography (KGF).
- Defined PCS as the side with the majority of chewing cycles analyzed.
Main Results:
- No statistically significant agreement was found between the two techniques used for PCS determination.
- Both methods indicated a marked preference for the right-hand side in the subjects studied.
Conclusions:
- Current methods for determining preferred chewing side may lack consistency.
- Despite methodological differences, a right-sided chewing preference appears prevalent.
