Seventeen studies were included. Most of the documents identified and covered generic aspects of delivering digital oral healthcare (n = 11) without explicitly referring to any dental specialty. The most mentioned legal issues were data security (n = 15); liability and malpractice (n = 14); consent (n = 12); and confidentiality (n = 12). To a lower extent, patient-practitioner relationship (n = 11); and license and jurisdiction (n = 11) were also covered. These were followed by privacy of information (n = 10); adequacy of records (n = 9); and e-referrals (n = 8). On the other hand, fewer studies commented on social media use (n = 3), authentication (n = 2); or e-prescriptions (n = 2). Before implementing any digital health solution, practitioners need to be aware of the many legal issues that the introduction of these technologies involves, be clear where the responsibility lies, and apply extreme caution in following national guidelines. Current literature concentrates on a few well-known legal issues. Issues around authentication, use of social media, and e-prescriptions received less attention.
