Marchetti G, et al. - Authors evaluated the influence of an App related to conventional educational methods in adolescents’ oral health. They noted the effectiveness of the App in increasing knowledge, especially associated with the video. For a better standard in oral hygiene, the different methods were equally effective. For all methods, there was a significant reduction in oral indexes. A significant increase in knowledge score (KS) was seen with video orientation (VG) + App in the follow-up test compared to the post-test.
