Abstract
Introduction: Gingival melanin hyperpigmentation is clinically presented as black gum
which is not medical but esthetic problem especially for those who have gummy
smile. Various treatment modalities have been made for cosmetic removal of
pigmented area including gingival melanin hyperpigmentation
by Er:YAG laser. Laser ablation which recently seems to be the most effective
reliable and satisfactory method.
Patients and method: Two patients with
gingival melanin hyperpigmentation were treated by
2940 nm Er:YAG laser device
which was set at 1.0, 1.75 watt, 7% water and 11% air for gingival ablation,
and then 0.5 watt, 0% water and 11% air for biologic bandage. The operation was
done in noncontact mode under topical anesthesia. Patients were observed for 12
months.
Results: Removal of melanin pigment was seen
immediately after treatment healing was good within a week. No postoperative complications
such as infection, pain or bleeding was encountered. The final outcome was
satisfactory for all patients. However, second applications may be needed.
Slight repigmentation was found in one patient in the
eleventh month of observation.
Conclusion: considering good clinical outcome
and patients satisfaction, Er:YAG
laser ablations possibly a method of choice for effective removal of gingival
melanin hyperpigmentation.
