Adhesion of Porphyromonas gingivalis and Biofilm Formation on Different Types of Orthodontic Brackets
Figure 1
The mean log-transformed number and standard deviation of adhering P. gingivalis to the 3 types of brackets ( for each column). The first two sets of columns represent the effect of saliva coating (data is combined for the mono- and multispecies conditions). The other 2 groups present the mean numbers of P. gingivalis adhering alone or in combination with the other added bacterial species (Pg+) (data is combined for the nonsaliva and saliva coating conditions). (SS: stainless steel, PL: plastic, and CE: ceramic brackets).
