Plain-language summary

This study aimed to translate the Helkimo Clinical Dysfunction Index (HCDI) into Turkish and to test its validity and reliability as an outcome measurement method in individuals with temporomandibular dysfunction (TMD). The study included 40 patients. Participants' pain intensity and range of jaw movement were measured, followed by the administration of the HDCI, the Fonseca Anamnestic Index (FAI), and the Mandibular Function Impairment Questionnaire (MFIQ). For test-retest reliability, the same questionnaire was administered again to the same patients two weeks later, and the FAI was used to test the validity of the questionnaire.
