About

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.

Full description

Based on the idea of making the Helkimo Clinical Dysfunction Index (HCDI) available in Turkish, our study aimed to translate this scoring system into Turkish and to test its validity and reliability as an outcome measurement method in individuals with temporomandibular dysfunction (TMD). The study aimed to include 40 patients. Pain intensity during palpation and chewing was measured using a numerical pain rating scale (NPRS), and range of jaw movement was measured using a linear ruler. Participants were then administered the HCDI, the Fonseca Anamnestic Index (FAI), and the Mandibular Function Impairment Questionnaire (MFIQ). To assess test-retest reliability, the same questionnaire was administered again to the same patients after two weeks. The FAI was used to test the validity of the questionnaire.
