%X Background and Design: Although gingival hyperpigmentation is not a medical problem, people who have moderate or severe gingival pigmentation, particularly patients having a gummy smile, frequently request cosmetic treatment. For gingival depigmentation, different treatment modalities have been reported such as surgical treatment, cryotherapy, electrosurgery, and laser therapy. Materials and Methods: Twenty-one patients with gingival melanin pigmentation were included in the study. We applied liquid nitrogen to the hyperpigmented area for 5-10 seconds using open spray technique with a cryogun. Clinical observations for intensity of pigmentation were recorded at baseline and 3 months after the treatment. Clinical parameters, such as bleeding, swelling, redness, and healing, were evaluated immediately after the cryotherapy and 24 hours, and 1 week after the treatment. We used a numeric pain scale to evaluate the pain level. Results: Three months after the treatment, the mean gingival melanin pigmentation score decreased from 41.62¡À16.58 to 19.28¡À11.85. The difference between pretreatment and posttreatment mean scores was found to be statistically significant.Discussion: Removal of gingival melanin pigmentation can be performed safely by open spray cryotherapy in dermatology clinics.
