Applicability of the Geographic Tongue Area and Severity Index among Healthcare Professionals: A Cross-Sectional Clinical Validation of a Newly Developed Geographic Tongue Scoring System.

Whilst the validation of GTASI applicability was successfully executed, the general dental practitioners, specialists in oral medicine and dermatologists were equally capable of correct GT diagnosis and appropriately rating its severity. These coherent results were especially replicated among the experienced clinicians. The validation of the newly proposed index confirmed its reliability as a feasible instrument in oral medicine, with the prospect of its wider implementation in clinical practice.
