Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: similar results of maximum strain and deformation forces for all ligatures are expected after the use of whitening and control dentifrices, verified by the tensile test from the absence of a statistically significant difference of at least 5%;Outcome 1: it was observed that the 3M ligatures showed a reduction in the maximum strain force and the Orthotechnology ligatures showed less deformation after the use of whitening and control dentifrices, verified by the tensile test based on the finding of statistically significant differences (p lower than 0.05);Expected outcome 2: color change results are expected to be above a clinically perceptible level in all ligatures following the use of whitening and control dentifrices, verified by photography and spectrophotometry from the finding of no difference by visual means and no statistically significant difference of at least 5% respectively;Outcome 2: it was observed that results of color change above a clinically perceptible level were found in all ligatures after the use of whitening and control dentifrices, verified by photograph color assessments from the absence of visual differences and by spectrophotometry from the finding of absence statistically significant difference (p higher than 0.05);Expected outcome 3: non-differential colonization of microorganisms is expected to be found in all ligatures after the use of whitening and control dentifrices, verified by the microbial culture method from the finding of no statistically significant difference of at least 5%.;Outcome 3: it was observed that non-differential colonization of microorganisms was found in all ligatures after the use of whitening and control dentifrices, verified by the microbial culture method from the absence of a statistically significant difference (p higher than 0.05).;Expected outcome 4: similar surface structures are expected to be found for all ligatures after the use of whitening and control dentifrices, verified by the s | — |
