Summary
Intense chewing temporarily reduces masticatory efficiency, maximal occlusal force, and endurance. These effects on chewing function resolved within days, returning to baseline measurements.
Area of Science:
- Dentistry
- Biomechanics
- Human Physiology
Background:
- Masticatory function is crucial for nutrient intake and overall health.
- Understanding the short-term effects of intense chewing on oral motor function is important for clinical and research applications.
Purpose of the Study:
- To investigate the immediate and short-term effects of 30 minutes of intense chewing on masticatory function in healthy adults.
- To quantify changes in mandibular movements, masticatory efficiency, occlusal force, and endurance.
Main Methods:
- 17 healthy subjects underwent functional recordings of mandibular movements and velocity.
- Measurements included masticatory efficiency, maximal occlusal force, and occlusal force endurance time.
- Data were collected before, immediately after, and during a 2- to 5-day follow-up period post-intense chewing stimulation.
Main Results:
- A significant decrease in masticatory cycle and occlusal level phase duration was observed post-chewing.
- Masticatory efficiency and maximal occlusal force, particularly in the incisal region, were diminished.
- Occlusal force endurance time also showed a reduction, with most measurements returning to baseline by follow-up.
Conclusions:
- 30 minutes of intense chewing induces short-term impairments in masticatory function.
- These impairments include reduced efficiency, maximal force, endurance, and cycle duration.
- Masticatory function demonstrates resilience, with recovery observed within a few days.
