EVALUATION OF INNOVATIVE DIGITALLY CONTROLLED ER:YAG LASER IN SURGICAL TREATMENT OF ORAL LEUKOPLAKIA - A PRELIMINARY STUDY.

ABSTRACT

The use of lasers for treatment of oral leukoplakia has gained a lot of interest in the past years, however, data on the use of ErYAG laser are scarce. The aim of this study was to compare the efficacy of ErYAG laser and 1% topical isotretinoin in the treatment of 27 oral leukoplakia patients. ErYAG laser (LightWalker AT, Fotona, Slovenia) was used in 27 patients with 27 leukoplakia lesions. Postoperative pain was assessed by use of visual analog scale (VAS), and the impact of laser treatment on the quality of life was assessed by the OHIP-14 questionnaire (Croatian version). Control group consisted of the same 27 patients previously treated with 1% topical isotretionin three times a day during the period of one year. No improvement in the size of leukoplakia lesions was observed after treatment with topical isotretinoin. There were significant differences between men and women according to leukoplakia localization, number of laser sessions and VAS (p<0.05). At follow-up after six months and one year, there was no recurrence of lesions. ErYAG laser is a successful treatment for oral leukoplakia. Topical isotretionin treatment is unsuccessful in patients with oral leukoplakia.
