WebFor plating to a 100 mm plate, 100–200 µL of cell suspension generally works well. If very few colonies are anticipated, the entire cell suspension may be plated. However, if a very high number of colonies is expected, the cell suspension may be diluted up to 1:100 in S.O.C. medium before plating to avoid the formation of a bacterial lawn. WebThe present study found differences in the number of S. mutans colonies between both groups of brackets in which CL showed more accumulation of bacteria. Some studies show that the SL brackets present better hygiene, 8,11 and they are less susceptible to bacterial colonization due to their shape and lack of wire or elastomeric ligatures. 12
