Baseado nos resultados do presente trabalho in vitro, pode-se concluir que tanto a aplicação do plasma frio de argônio em pressão atmosférica como a PDI mediada pela combinação curcumina/EDTA podem reduzir significativamente a viabilidade do S. mutans por meio das ROS geradas por ambos tratamentos. Deste modo, ambos tratamentos se apresentam como técnicas promissoras para reduzir a viabilidade de S. mutans.
