خلاصه	The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) is a comprehensive, evidence-based diagnostic system for identifying and classifying temporomandibular disorders (TMD)—a group of painful and functional conditions affecting the jaw joint, muscles of mastication, and related structures. Originally developed in 1992 by Schiffman and colleagues and updated to the Diagnostic Criteria for TMD (DC/TMD) in 2014, the RDC/TMD is the international gold standard for TMD diagnosis in research and clinical practice. It combines structured patient history, pain questionnaires, and standardized clinical examination to reliably diagnose muscle disorders, intra-articular disorders, and headache associated with TMD.	The Modified Dental Anxiety Scale (MDAS) is a brief 5-item self-report instrument measuring anxiety anticipation and response to common dental situations. Developed by Humphris and colleagues in 1995 as a refinement of prior instruments, the MDAS has become the gold standard for rapid dental anxiety screening in clinical practice and research. Its brevity, psychometric rigor, and clinical utility have made it the most frequently used measure of dental anxiety internationally.	The Xerostomia Inventory (XI) is an 11-item self-report questionnaire designed to measure subjective perception of dry mouth (xerostomia). Developed by Thomson and colleagues in 1999, it has become the standard validated instrument for assessing dry mouth severity in clinical practice and research. The XI captures both the frequency and severity of oral dryness symptoms and their impact on daily functioning, distinguishing symptomatic xerostomia from objective salivary gland dysfunction.
