Summary

This double-blind randomized clinical trial evaluated the effect of 1.5% potassium oxalate on pain sensitivity control and color change after home tooth whitening. It also evaluated the influence of potassium oxalate on health-related quality of life (HRQOL) and on the degree of patient satisfaction after bleaching treatment.

Conditions

• Dentin Sensitivity

Interventions

Type	Name	Description
OTHER	Carbamide Peroxide (PC) 22%) + placebo gel	Application of one drop of Polanight bleaching agent (SDI, SP, Brazil) on each corresponding tooth in a tray that was used for 45 minutes a day, for a period of twenty-one days. After the bleaching treatment, the participants were instructed to wash the trays under running water and dry them. The volunteers were instructed to apply a small amount of placebo gel, without active ingredient, with color, texture and odor similar to 1.5% oxalate gel (Painless, BM4, SC, Brazil) in the spaces related to the vestibular portions of the teeth trays, which were used for 10 minutes.
OTHER	Carbamide Peroxide (PC) 22%) + Potassium Oxalate gel 1.5%	Application of one drop of Polanight bleaching agent (SDI, SP, Brazil) on each corresponding tooth in a tray that was used for 45 minutes a day, for a period of twenty-one days. After the bleaching treatment, the participants were instructed to wash the trays under running water and dry them with absorbent paper. The volunteers applied a small amount of 1.5% potassium oxalate gel (Painless, BM4, SC, Brazil) in the spaces relative to the vestibular portions of the tray's teeth, which were used for 10 minutes.
