Table 1 Settled dental aerosol and splatter for the orthodontic debonding procedure as measured by contaminated surface area using image analysis or by spectrofluorometric analysis. For each experimental condition, the data from three repetitions for all samples at each location are included together. RFU: relative fluorescence units.
