“…None of our patients developed purpura or ecchymoses, although some patients had reddish‐pigmented macules, which appeared to be secondary to scratching and resolved completely within days. Bernstein reported four cases of severe urticaria that occurred immediately after laser epilation and that lasted many days 10. The clinical picture of all four patients was similar to that of our series of patients, although the onset of the urticaria in the Bernstein study occurred within 24 hours, unlike the longer delayed onset (6 hours to 5 days) observed in our study.…”

Persistent urticaria is a rare side effect of laser epilation. Rupture of the hair follicle by laser heat may trigger a delayed hypersensitivity reaction in a subset of predisposed allergic patients. An antigen from the disrupted hair follicle may be the triggering factor. To prevent this side effect, we recommend that laser epilation in allergic patients be preceded by an extended laser patch test, which should be evaluated 24-48 hours later. Preventive prednisone should be prescribed to patients who develop an urticarial rash on the test area.

“…Severe, persistent urticaria may occur in patients who had previously tolerated a similar procedure and do not have a history of urticaria with physical stimuli. This pathogenesis is unclear but may be attributed to an allergic reaction to the cryogen cooling spray or sensitivity to specific wavelengths of light . Lastly, long‐term hyperhidrosis may result after treatment of axillary hair with the Nd:YAG laser, perhaps due to a stimulatory rather than destructive effect on eccrine sweat glands .…”

Introduction: Pigmentation of the gingiva is a negative factor in an otherwise acceptable "smile window." Recently, cryosurgery and laser techniques have gained popularity for depigmentation and seem to be the most reliable and satisfactory procedures. To our knowledge, this case series is unique and is the first reporting comparison of cryosurgery and lasers in the literature. Case Series:The study included 20 patients who presented with a chief complaint of "black gums" and requested cosmetic therapy. They were randomly divided into group A and group B of 10 patients each. Patients in group A were treated using a diode laser. The laser beam was set at 0.70 W power, 200 J energy, in continuous mode. Patients in group B were treated using tetrafluoroethane cryosurgery. Patients were followed for 3, 6, 12, and 18 months. Gingival depigmentation was assessed using a new index system, gingival pigmentation index, on the day of first depigmentation and at the end of 18 months. Patient satisfaction was evaluated by using a simple questionnaire. Both procedures were equally effective in depigmentation. At the 18-month follow-up, spotted repigmentation was found in one case in each group. Although there was initial healing discomfort and mild pain with cryosurgery, all the patients were satisfied with the esthetic outcomes.Conclusion: During the 18-month follow-up, the depigmentation achieved using both the techniques was found equivalent and satisfactory.
