Objectives

Narrative objectives1

This research aimed to verify the significant parameter that can distinguish between the true bruxism and bruxism like hyper muscle activities (swallowing, head motion, scratching). Thus, individual EMG and auscultatory sound ware compared in order to verify the parameter.

Assessment

Primary outcomes

After obtaining the EMG of true bruxism and bruxism like muscle hyper activity events, these will be compared and analyzed by the hidden Markov model. Then, Mel Frequency Cepstral Coefficient will be calculated individually.

Key secondary outcomes

After obtaining the auscultatory sound of true bruxism and bruxism like muscle hyper activity events, these will be compared and analyzed by fast Fourier transform. Then specific frequency that can distinguish between the true bruxism and bruxism like muscle hyperactivity events will be evaluated.

the hidden Markov model. Then, Mel Frequency Cepstral Coefficient will be calculated individually.

Interventions/Control_1

In the supine position, subjects are asked to bite and tighten at the molars. Continue this task for 10 seconds and perform it 3 times. Rest for 20 seconds between each task.

Interventions/Control_2

In the supine position, subjects are asked to make muscle hyper activities without tooth contacting for 10 seconds, and perform it 3 times. Rest for 20 seconds between each task.

Interventions/Control_3

In the supine position, subjects are asked to swallow 3 times during 10 seconds. Rest for 20 seconds between each task.

Interventions/Control_4

In the supine position, subjects are asked to scratch the electrode. Continue this task for 10 seconds and perform it 3 times. Rest for 20 seconds between each task.

Interventions/Control_5

In the supine position, subjects are asked to make head motion. Continue this task for 10 seconds and perform it 3 times. Rest for 20 seconds between each task.

Interventions/Control_6

In the supine position, subjects are asked to make somniloquy . Continue this task for 10 seconds and perform it 3 times. Rest for 20 seconds between each task.

Interventions/Control_7

In the supine position, subjects are asked to snore. Continue this task for 10 seconds and perform it 3 times. Rest for 20 seconds between each task.
