Abstract: The study of atmospheric pressure plasma technology has become a prominent area of research due to its diverse applications in health. Areas such as pollution control, materials processing, electrochemistry and engineering as a whole have this technology as very relevant. The moment in which the chemical species in the plasma reach the treated surfaces still requires studies, so the current search aims to obtain deeper knowledge for applications in dentistry. Special attention is paid to the biological and surface effects of plasma-generated reactive species. This research aims to use the Optical Emission Spectroscopy (EEO) technique, a tool for plasma diagnosis, detection of reactive species and their identification, as well as the analysis of how they behave according to the parameters adopted in the process of obtaining plasma by Dielectric Barrier Discharge (DBD). To carry out this analysis, it was necessary to follow the steps of searching for articles to carry out the bibliographic review, laboratory experiments to obtain data and analysis of reactive species. The results include graphs of the plasma spectrum, with its respective parameters, as well as the identification of its chemical species, with thermal images of some samples under the influence of the plasma plume, considered critical for dentistry. It is concluded that the study of reactive species is very important for several areas, especially dentistry, as chemical species not only carry out surface modifications, increasing the energy applied, but also inactivate unwanted microorganisms, with a sterilizing effect
