概要	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.
