Introduction:

The manufacturers of DMC 35% hydrogen peroxide propose a whitening technique of vital teeth that waste the product and the time of treatment, so a modified technique would bring material and economic benefits for operators and patients.

Objective:

To describe the application of a modified technique in vital teeth whitening using DMC 35% hydrogen peroxide.

Case presentation:

A 44-year-old female patient undergoing a whitening treatment with a modification of the technique proposed by the product manufacturer. The modification consisted in the use of a single application of the bleaching gel instead of three applications, and an increase in the exposure time to 40 min instead of the 10-15 min recommended by the manufacturer. The variables used to evaluate the treatment and its results were defined by the registration of the color before and after treatment and also by the satisfaction of the patient with the result. The teeth exposed to treatment were found with healthy enamel tissues without dentine exposure on any of the surfaces.

Conclusions:

The described modification of the whitening technique proposed by the manufacturer with DMC Lase Peroxide Sensy (35% hydrogen peroxide) consisting mainly on the use of a single application and the increase of the exposure time in a single treatment session contributed to a considerable saving of the product and led to the change of the final coloring of the teeth, which resulted in the full satisfaction of the patient and the protection of her exposed teeth and tissues.
