Design outcomes

Primary

MeasureTime frame
It is expected to observe the reduction of dental sensitivity through the application of potassium nitrate and sodium fluoride desensitizers (Experimental Group 1) and nanostructured calcium phosphate (Experimental Group 2) verified through the visual analogue pain scale ( VAS) at the beginning, during and at the end of the study.—

Secondary

MeasureTime frame
It is expected to observe the teeth whitening of all patients in the research, using 35% hydrogen peroxide bleaching gel, verified by color evaluation with digital spectrophotometer.—
