This document discusses bruxism, a medical condition where people grind their teeth or clench their jaws. It analyzes EEG signals to help diagnose bruxism. The key points are: - Bruxism is the grinding or clenching of teeth and can cause jaw pain and damage teeth over time. It often occurs during sleep. - EEG signals measure brain wave patterns and are used to analyze alpha, beta, gamma, theta, and delta waves to help diagnose bruxism. - MATLAB coding was used to compare original and filtered EEG wave signals between a bruxism patient and normal person. The results clearly showed a difference, aiding in prognosis of bruxism.
