DIAZ DEL MAZO, Lizel et al. Effectiveness of laser therapy combined with the conventional technique in patients with dental dischromya. MEDISAN [online]. 2021, vol.25, n.2, pp. 292-304. Epub 29-Mar-2021. ISSN 1029-3019.
Introduction:
The dental dischromya is an esthetic disorder, of multifactorial cause, characterized by the change of coloration of one or several teeth.
Objective:
To evaluate the effectiveness of laser therapy as a source of light and heat in patients with dental dischromya.
Method:
A quasi-experiment, of therapeutic intervention study, was carried out in 24 patients with dental dischromya assisted in Mártires del Moncada Teaching Provincial Stomatological Clinic in Santiago de Cuba, from July, 2017 to March, 2018. The members of the study were assigned at random with 2 treatment groups: a study group (pairs) to whom laser combined with the conventional technique of peroxide of hydrogen was applied; to odd number patients (control group), conventional treatment only. The absolute and relative frequencies were used as summary measures, as well as the chi-square test of homogeneity for the statistical validation, with a level of significance of 0.05.
Results:
For the patients of the study group, the second and third sessions were more effective. When culminating the treatment, both were effective, but those that received laser evolved more quickly than those treated with peroxide of hydrogen.
Conclusions:
The use of the laser therapy and peroxide of hydrogen was effective in patients with dental dischromya and it was demonstrated that doesn't cause adverse effects in the treated teeth.
