Introduction:

ozone has been studied and applied with great success in different areas of Stomatology, a premise that imposes the need for professionals to become familiar with new procedures for patients with dyschromia.

Objective:

to evaluate the effectiveness of Oral OLEOZON® as an alternative treatment for dyschromia of devitalized permanent uniradicular teeth in patients treated at the Stomatology Service of the Policlínico Universitario Sur of Morón municipality.

Methods:

experimental study, with pretest/posttest design and control group, during January 2020 until April 2021. We worked with the total universe, constituted by 18 patients, nine integrated the study group (OLEOZON® Oral) and nine the control group (hydrogen peroxide at 30 %). Descriptive and inferential statistics were used.

Results:

as the days of evolution elapsed, the color change varied in each of the groups. At 35 days after the treatments were applied, 75,0 % of the controls and 50,0 % of the study group achieved a total color change (desired color) according to the shade guide used at all times during the intervention. The Mann-Whitney U test and the Kruskal-Wallis test were not significant, so there were no statistical differences between the results obtained in each of the treatment groups, there being homogeneity between them.

Conclusions:

there was a variation in the color of the tooth in each of the groups under study, so it could be inferred that the treatment with OLEOZON® Oral was effective.
