Comparative evaluation of depigmentation techniques in split-mouth design with electrocautery and laser

Abstract

Excessive gingival pigmentation is a major esthetic concern for many people. Melanin pigmentation is known to be caused by melanin granules within the gingival epithelium. Smile is determined not only by the shape, the position, and the color of the teeth, but also by the gingival tissues. Gingival health and appearance are essential components of an attractive smile. It is not a medical problem, but it feels unesthetic for the patient and particularly in patients having a very high lip/smile line. Depigmentation is not a clinical indication but a treatment of choice where esthetics is a concern and is desired by the patient. For depigmentation of gingival, different treatment modalities have been reported such as bur abrasion, scraping, partial thickness flap, cryotherapy, electrosurgery, and laser. The present case series describes two simple and effective surgical depigmentation techniques treated with diode laser and electrosurgery.

Evaluation the rate of recurrence of gingival pigmentation removed by cryotherapy and electrosurgery for 6 months

“…While no significance difference was found when comparing between the DOPI at 3 months and 6 months. This is in agreement with Elavarasu et al (2015) (17) who made a comparative evaluation of depigmentation techniques in split-mouth design with electrosurgery and laser, in regarding to electrosurgery group after patient evaluation for 3 months they found healthy pink gingiva with no repigmentation. Concerning cryosurgery group significance differences were found when comparing the preoperative score of DOPI versus both after 3 and 6 months, while no significance difference was found when comparing between DOPI at 3 months and 6 months.…”

“…Elavarasu et al [19] also reported similar results in a comparison between electrocautery and laser therapy.…”

“…Chandna et al [ 6 ] compared and evaluated pain using electrosurgery and a diode laser for a depigmentation treatment and found that electrosurgery can result in uncontrolled necrosis of the tissue whereas lasers offer a controlled range of treatment, making them a better choice than electrosurgery. Elavarasu et al [ 19 ] also reported similar results in a comparison between electrocautery and laser therapy.…”

DIODE LASER IN PERIODONTAL TREATMENT (Tinjauan Pustaka)

“…2 Pada perawatan depigmentasi gingiva dapat dilakukan dengan bur abrasive, scraping, flap ketebalan sebagian, cryotherapy, electrosurgery dan laser diode. 13 Laser diode merupakan pilihan perawatan yang menjanjikan karena alat ini sederhana, tidak menimbulkan rasa sakit karena terbentuknya protein koagulum dan meninggalkan medan darah yang lebih sedikit dengan mengeblok pembuluh darah kecil dan limfatik sebagai hasil dari generasi panas. Prosedur rasa sakit mungkin terjadi peningkatan ambang rasa nyeri setelah laser menghasilkan blockade saraf, khususnya penghambatan serat saraf A dan C. Penghambatan ini dapat dimediasi dengan mengubah aliran aksonal atau dengan menghambat enzim saraf.…”
