Participants will be recruited from an endodontic clinic after ethics committee approval. Resting-state EEG will be recorded using a wearable EEG system prior to treatment. Post-operative pain intensity will be assessed using a patient-reported Visual Analogue Scale (VAS) during the early post-treatment period.\n\nParticipants will be classified based on baseline alpha activity (e.g., lower versus higher alpha power range). Analyses will evaluate whether baseline EEG alpha measures are associated with subsequent pain ratings and whether differences in alpha activity relate to higher post-operative pain susceptibility. The goal is to determine whether EEG alpha activity may serve as a practical biomarker for post-endodontic pain susceptibility.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '40 Years', 'minimumAge': '20 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'The study population consists of patients seeking dental treatment at the Department of Endodontics, Faculty of Dentistry, Ain Shams University.', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion criteria:\n\n1.
