Abstract :
Melanin hyperpigmentation is the result of melanin granules. "Black gums" may cause esthetic problems. Different treat-ment modalities have been used with the aim of removing pigmentations for esthetic reasons, all of which have some advan-tages and disadvantages. Recurrent lesions are the most important concept in all of these treatments. Cryotherapy is a method of tissue destruction by rapid freezing. It is an atraumatic, cost-effective and simple method for treating oral pig-mentation. This report presents the effects of cryotherapy on physiologic pigmentations of oral mucosa in a 9-year-old boy. In this case no recurrent lesions were observed after 12 months.
