CACERES SANDI, Oscar et al. Focal multiepithelial hyperplasia: comparative treatment, glycyrrhizinic acid versus liquid nitrogen. Rev. Odont. Mex [online]. 2015, vol.19, n.2, pp.101-105. ISSN 1870-199X.

In pediatric population, focal multiepithelial hyperplasia (FMH) is characterized by the onset of multiple lesions in the mucosa of the mouth; it is associated to the human papillomavirus. Presently, no special treatment is preferred, the most widely used is liquid nitrogen (LN) treatment, nevertheless, this is an uncomfortable and painful treatment for the patient. This would prompt us to look for new, less invasive treatment alternatives such as use of glycyrrhizinic acid (GA). Aim: To compare GA efficiency versus LN in FMH in Mexico Children's Hospital patients (HIM) aged 5 to 13 years. To determine clinical epidemiological characteristics as well as adverse effects. Material and methods: The present was a randomized controlled clinical trial. It was divided into two groups: group A was treated with GA applications, four times a day, two atomizer shots, for one month. Group B was treated with LN once a month for three months. Results: 20 pediatric-age patients were studied, out of which 11 were male and 9 female. 12 patients had relatives afflicted with the disease. Most frequent topography was the lower lip. Efficiency of group treated with GA was 63% when compared to group treated with LN which exhibited 81% efficiency. Systemic diverse effects were only observed with use of LN. 0.075 p was obtained (7.5%). Conclusions: GA efficiency was ascertained although it was lesser than that of LN. GA can be used as an adjuvant treatment in order to decrease lesions, it elicits minimal local adverse effects.
