Cognitive behavioral therapy eases orthodontic pain: EEG states and functional connectivity analysis

Area of Science:

• Neuroscience
• Pain Management
• Psychology

Background:

• Orthodontic pain significantly impacts patient quality of life.
• Understanding the neurophysiological underpinnings of pain is crucial for effective management.

Purpose of the Study:

• To evaluate the impact of Cognitive Behavioral Therapy (CBT) on electroencephalogram (EEG) activity in individuals experiencing orthodontic pain.
• To explore the relationship between EEG changes and pain processing during orthodontic treatment.

Main Methods:

• A randomized controlled trial involving 24 young adults, comparing a CBT group to a control group.
• Continuous EEG and visual analog scale (VAS) pain scores were recorded before, during, and after archwire placement.
• A 1-month follow-up assessed daily pain scores.

Main Results:

• The CBT group showed reduced overall EEG spectral power, particularly in theta and beta frequency bands.
• Enhanced coupling of theta and beta frequencies was observed in specific brain regions.
• EEG power in delta and theta bands positively correlated with reported pain intensity.
• CBT group exhibited increased network coherence in the theta band.

Conclusions:

• Continuous EEG can detect specific cerebral responses to CBT in orthodontic pain.
• These findings suggest a potential neurophysiological mechanism for CBT in orthodontic pain control.
• EEG monitoring may offer new avenues for assessing CBT efficacy in pain management.
