Turkish Version of Helkimo Clinical Dysfunction Index
Sponsor: Sevgi Medical Center
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.

Turkish Version of Helkimo Clinical Dysfunction Index and Accompanying Scales
The intervention includes a detailed clinical assessment and a series of questionnaires. Participants will provide demographic data, trauma, and surgical history. Clinical evaluation includes the measurement of pain and jaw movements. Subjective symptoms will be assessed using the Numerical Pain Rating Scale (NPRS), linear ruler, Fonseca Anamnestic Index (FAI), and Mandibular Function Impairment Questionnaire (MFIQ). The Turkish version of the Helkimo Index will be administered to test its validity and reliability. To evaluate test-retest reliability, the entire procedure will be repeated for a subgroup after 14 days.
