Abstract: The aim of this multicentric study was to assess the diagnostic accuracy of a telediagnosis service for oral mucosal disorders. This study included 100 patients seen at the oral medicine outpatient clinic of 3 Brazilian Dental Schools (University of Campinas, Federal University of Pernambuco, and Federal University of Santa Catrina) from March 2019 to October 2019. In addition to the face-to-face assistance provided by graduate students and the final diagnosis validated by the professors of these institutions, a remote evaluation was requested for these patients through the EstomatoNet/TelessaúdeRS platform. The sensitivity and specificity of telediagnosis were compared with those of the face-to-face approach and found to be 100% and 97.4%, respectively. The concordance between the examiners was 95%, and case management was relatively simple in approximately 60% of cases. Based on the results, telediagnosis for oral diseases can be considered a reliable method, representing a promising alternative for the clinical support of health professionals, particularly in remote locations Ver menos
