Background: In Esthetic zone, the gingival labial margin position is an important parameter for ideal smile. Excessive gingival displays are major concerns for a large number of patients. Hyperpigmentation of gingiva is pronounced if it is related with short clinical crown. Surgical crown lengthening and depigmentation can be performed together to help improving patient satisfaction. Laser therapy is one of the alternative treatment that can be used in such situation. Objective: This case report presents the surgical crown lengthening and depigmentation by using Er:YAG and diode laser in esthetic zone. Method: A 19-year-old Thai female patient was referred for increasing clinical crown and depigmentation in esthetic zone. Upper anterior teeth (13-23) was found gummy smile appearance and she had hyperpigmentation on her anterior gingiva. There was no pocket formation and keratinized gingiva was 6-8 mm. All upper anterior teeth was performed to decreasing the height of gingival margin by using Er:YAG laser at 150 mJ, 10 Hz. 1-2 mm. with water spray expressed, followed with ostectomy to reduce the bone level 1-2 mm. by using Er:YAG laser at 300 mJ, 10 Hz. with water spray expressed. Finally, hyperpigmentation of gingiva was depigmented by diode laser 2 watt. Paracetamol and chlorhexidine 0.12% were prescribed after surgery. Results: No sign of infection and inflammation, no complain about pain or unexpected result in 7 days and the clinical crown was found increase 1-2 mm. After 1 month follow-up, result showed excellent color, contour and margin of the gingiva. Patient was very appreciated with the new appearance. Conclusion: Laser therapy can be considered alternative treatment or assisted periodontal management for esthetic crown lengthening and depigmentation.
