A 3  months clinical evaluation comparing two professional bleaching systems of 25% and 40% hydrogen peroxide and extended treatment outcome using a power versus a manual toothbrush

ConclusionsAt Day 7, PZW showed statistically greater change in overall color and shade than UOB. The SDC maintained tooth shade significantly better than MTB. Both bleaching regimens were safe.Clinical SignificanceThe outcomes confirm the bleaching efficacy advantage of a lower H2O2 dose ‐LED accelerated professional tooth bleaching system, compared to a higher‐dose H2O2 approach. The safety assessments via clinical intraoral exam and daily logged use of subjects' desensitizing agents, and the incidence and severity of reported sensitivity, provide evidence that both professional products are safe for use. Finally, powered tooth brushing may confer an advantage to manual tooth brushing in maintaining tooth shade ‐change results following professional whitening.
