Summary

This study aimed to find out how many people with trigeminal neuralgia (a severe facial nerve pain condition) also have temporomandibular disorder (TMD), which causes jaw pain. Researchers planned to follow patients from three clinics and test a questionnaire to better diagnose both conditions. However, the study was withdrawn before enrolling any participants.
