Video training for dental sealants: just as good as In-Person?

This study tested whether intern dental students can learn to place pit and fissure sealants (a coating that prevents cavities) effectively through a video demonstration instead of in-person training. Fifty children aged 7-9 received sealants on their lower first permanent molars, with one tooth treated by a student trained via video and the other by a student trained in person. After 3 months, researchers checked how well the sealants stayed in place and whether there was any discoloration at the edges.
