[The value of dental imaging in the teaching and promotion of oral health]

In the context of the great diversity of oral microflora, including over 600 species, we highlight the educational value of electron micrographs and images of dental plaque cultures in dental models made with culture media, showing the bacterial colonies in the anatomic sites of the teeth that were most abundantly colonized. Such images allow for an easy understanding of the magnitude of the oral microbiome for students of biomedical careers--especially dentistry--and for the general public. As such, these images can be used in teaching programs and oral health campaigns.
