Microbial ecology and bacterial co-occurrence. The most expressed interactions were observed between Streptococcus species. In the NPT were observed only positive interactions for Streptococcus mitis/oralis/pneumoniae, Rothia aeria/dentocariosa, Prevotella loescheii, Haemophilus parainfluenzae, Veillonella dispar, Rothia dentocariosa, Fusobacterium nucleatum, Streptococcus mitis and Neisseria oralis. In the PT group, Streptococcus mitis was positively associated with Rothia aeria/dentocariosa and negatively associated with Parvimonas micra, Porphyromonas endodontalis and Prevotella oris. Negative interactions between species are depicted in yellow, positive interactions in blue and insignificant interaction in grey
