Summary
This study reveals a significant interaction between the oculomotory (eye movement) and stomatognathic (jaw function) systems. Manipulating jaw position alters eye movement parameters, suggesting a strong connection regardless of age.
Area of Science:
- Neuroscience
- Ophthalmology
- Dentistry
Background:
- The oculomotory and stomatognathic systems are complex neural networks.
- Understanding their interaction is crucial for diagnosing and treating related disorders.
- Cranial nerves and the reticular formation act as key links between these systems.
Purpose of the Study:
- To investigate the functional relationship between the oculomotory and stomatognathic systems.
- To determine how morphofunctional changes in the stomatognathic system affect oculomotory parameters.
- To explore the role of cranial nerves and reticular formation in this interaction.
Main Methods:
- Optometric examinations were conducted on 100 participants (aged 6-78).
- Oculomotory parameters (convergence, divergence, near convergence point) were measured.
- Measurements were taken at rest, with maximal mouth opening, and with occlusal bite-blocking using tin foils.
Main Results:
- Bite manipulation and maximal mouth opening significantly altered all measured oculomotory parameters.
- These effects were consistent across different age groups and genders.
- No significant difference in reactions was observed between subjects with and without asthenopic symptoms.
Conclusions:
- A significant interaction exists between the oculomotory and stomatognathic systems.
- This interaction is influenced by jaw manipulation and mouth opening.
- Further interdisciplinary research is recommended to fully elucidate the correlation between these systems.
