Identification of Possible Trigeminal Neuralgia

Sponsor: University College, London

Summary

Trigeminal neuralgia (TN) is a severe type of non-dental orofacial pain that can feel like sudden electric shocks in the face and is often mistaken for tooth pain or other dental problems. This can lead to delays in referral and unnecessary, sometimes irreversible, dental treatment. The goal of this observational study is to evaluate how well a new questionnaire (IDentification of possible Trigeminal Neuralgia - IDTN) identifies adults with possible trigeminal neuralgia among patients attending hospital clinics with orofacial pain, with the aim of supporting its use in dental and general medical practice to improve early recognition and referral. The main questions it aims to answer are: * How accurately does the IDTN questionnaire identify patients with possible trigeminal neuralgia compared with the specialist clinical diagnosis? * Which combination of questionnaire items best supports a practical screening score for use in dental and/or general medical practice? Participants will: 1. Complete the IDTN questionnaire before their clinical appointment (either electronically or on paper) 2. Undergo their usual specialist clinical assessment, during which the final diagnosis will be recorded 3. Allow the research team to compare questionnaire responses with the specialist diagnosis (the reference standard) A subset of participants will also be asked to complete the questionnaire again a few days later to assess test-retest reliability.
