The article presents the Polish version of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), detailing the process of translation and cultural adaptation. Temporomandibular disorders (TMDs) are a heterogeneous group of conditions affecting the masticatory system, with symptoms including pain, limited jaw movement, and TMJ sounds. TMDs are a significant public health issue, affecting 5–12% of the population. The RDC/TMD, an evidence-based diagnostic method introduced in 1992, was later replaced by the DC/TMD, which is now the standard for reliable and valid diagnosis of TMDs. The DC/TMD consists of two axes: Axis I for physical diagnosis and Axis II for psychosocial and behavioral assessment. The Polish version was developed through a rigorous process involving 10 stages, including forward and backward translation, expert review, and cultural adaptation. The translation was validated by an expert committee to ensure cultural validity and accuracy. The DC/TMD is available on the INfORM website and includes detailed examination procedures, a scoring manual, and diagnostic algorithms. The DC/TMD provides a structured approach for clinical examination and diagnosis, incorporating both physical and psychosocial assessments. It is recommended for use in all patients with a potential TMD diagnosis. The article emphasizes the importance of the biopsychosocial model in TMD management, which is not yet fully accepted by all clinicians in Poland. The Polish DC/TMD is now available for use in clinical and research settings, facilitating the diagnosis and assessment of TMDs.The article presents the Polish version of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), detailing the process of translation and cultural adaptation.
