Cleveland Dental Institute
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.
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.
Inclusion Criteria: * Males and females * Age: 20-60 years. * Tooth #8 vital and mature. No history of dentoalveolar trauma. * Adequate coronal tooth structure. Exclusion Criteria: * Chronic periodontitis. * Vertical root fracture. * Immature teeth. * Necrotic teeth. * Systemic diseases that affect the healing process. * Non restorable teeth.
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.
