Hypothesis
Does facial vibrotactile stimulation increase salivary secretion?
Conclusion
Facial vibration at 89 Hz effectively stimulates salivary glands, increasing salivation in most subjects.
Supporting Evidence
- 89 Hz vibration was found to be the most effective frequency for increasing salivation.
- 95% of subjects showed increased salivation with at least one frequency of vibration.
- Salivation was measured using a standardized cotton roll method.
Takeaway
When you vibrate your face, it can make your mouth produce more saliva, like when you eat something tasty.
Methodology
Subjects were stimulated with vibration on the masseter muscle for 3 minutes, and saliva was collected using cotton rolls.
Potential Biases
Potential bias due to informal reporting from subjects about their salivation.
Limitations
The study had a small sample size and variations in individual responses to stimulation.
Participant Demographics
21 healthy volunteers aged 23 to 29 years, 14 male and 7 female.
