Summary

Observational study at CDI Cleveland Dental Institute. Investigators will assess the pain perception in one group of patients using two non-invasive methods. First, a numerical rate scale (NRS) and second, a brain wave EEG.

Detailed description

To generate the nociceptive stimulus, The investigators will apply cold (Endo-Ice) to a healthy upper incisor tooth #8. Inclusion criteria: Patients between 20 and 60 years old, with healthy teeth, no history of dental alveolar trauma, and no pulp chamber calcification. After the nociceptive stimulus, patients will write their pain perception on paper from 0 to 10, and at the same time, we will record the brain activity with a non-invasive EEG Emotiv. Then, we will correlate both methods.

Conditions

• Pain
• Electroencephalography
• Toothache

Interventions

Type	Name	Description
DEVICE	EEG EMOTIV	The teeth will be dried with 2x2 gauze; then, Endo Ice will be applied. The patient response will be written on a sheet numbering to choose from 0 to 10, and at the same time, the brain waves will be recorded through EEG.
