“…Furthermore, the diagnostic method termined the effectiveness of swab and probe cryosurgery methods in gingival pigmentation removal (26). Kumar et al, 2013, in their study showed that cryosurgery is an effective method for gingival depigmentation (27) The result of According to the findings of the present study, no significant difference was found between the 2 pigmentation removal methods. Farahmand et al, 2014, in their study conducted in Iran, investigating Er:YAG laser (Pd: 120 mj, RR:120 Hz) and cryosurgery methods, found no significant difference between the 2 methods and both were announced effective methods (28).…”

Background: Patients often complain about the esthetic problems of gingival pigmentation. The aim of this study was to compare the effectiveness and recurrence of diode laser 810 nm and cryosurgery for gingival depigmentation. Methods: A total of 12 patients with physiologic gingival pigmentation were selected. The inclusion criterion was the presence of gingival pigmentation of maxillary incisors and the exclusion criteria was the presence of systemic diseases or use of any drugs associated with gingival pigmentation. For further evaluation, photographs were taken before and after treatment within the same position and light. Color analysis was done using the Adobe Photoshop software. Patients were treated by diode laser 810 nm -2 w and on the opposite side cryosurgery was performed. Treatment was done under topical anesthesia if required. The laser beam was activated using the brush technique and in contact mode. Application period differed according to the degree of melanin pigmentation and epithelial thickness of the treated area. Cryosurgery was performed by a cotton swab. The swab was gently touched and rolled on the area for 10 to 15 seconds until the disappearance of gingival pigmentation. All patients were examined 1, 3, and 6 months after treatment. Results: Data were analyzed using the SAS software version 19. The degree of pigmentation was considered as follows: score1: mild pigmentation, score 2: average pigmentation, and score 3: intense pigmentation. The treatment of gingival pigmentation with laser and cryosurgery showed marked improvement of gingival pigmentation in both methods as well as no significant difference between the 2 methods after 1, 3, and 6 months of treatment. Conclusions: Both methods are appropriate for the treatment of gingival depigmentation and no significant recurrence was observed during the 6 months follow -up.

“…Some of them, such as chemical techniques, are no longer used, 7 but some others such as gingival abrasion are still practiced. 8 Cryosurgery 9 and laser therapy 10 have also been used for treatment of gingival pigmentation with promising results and have met patients' expectations. Traditional methods for treatment of gingival pigmentation including gingivectomy with free gingival autografting, electro-surgery and radio-surgery have disadvantages such as pain, high cost and risks of surgery, including scar formation, gingival recession, trauma to the bone and periosteum and delayed wound healing.…”

Efficacy of Conventional Laser Irradiation Versus a New Method for Gingival Depigmentation (Sieve Method): A Clinical Trial

et al. 2017

Introduction: Diode laser irradiation has recently shown promising results for treatment of gingival pigmentation. This study sought to compare the efficacy of 2 diode laser irradiation protocols for treatment of gingival pigmentations, namely the conventional method and the sieve method. Methods: In this split-mouth clinical trial, 15 patients with gingival pigmentation were selected and their pigmentation intensity was determined using Dummett's oral pigmentation index (DOPI) in different dental regions. Diode laser (980 nm wavelength and 2 W power) was irradiated through a stipple pattern (sieve method) and conventionally in the other side of the mouth. Level of pain and satisfaction with the outcome (both patient and periodontist) were measured using a 0-10 visual analog scale (VAS) for both methods. Patients were followed up at 2 weeks, one month and 3 months. Pigmentation levels were compared using repeated measures of analysis of variance (ANOVA). The difference in level of pain and satisfaction between the 2 groups was analyzed by sample t test and general estimate equation model. Results: No significant differences were found regarding the reduction of pigmentation scores and pain and scores between the 2 groups. The difference in satisfaction with the results at the three time points was significant in both conventional and sieve methods in patients (P = 0.001) and periodontists (P = 0.015). Conclusion: Diode laser irradiation in both methods successfully eliminated gingival pigmentations. The sieve method was comparable to conventional technique, offering no additional advantage.

“…Debido a la presencia de pigmentaciones en esta región, existen distintos métodos utilizados para la despigmentación de manchas provocadas por melanosis como el láser (14-17), la criocirugía (17,18), mediante instrumentos rotatorios (18), ácido ascórbico (19), bisturí (20), injerto gingival libre (21), aloinjerto de matriz dérmica acelular (22), y radiocirugía (23); pero estas técnicas tienen desventajas como el ser costosas, requerir anestesia y/u otro método quirúrgico, y en algunos casos de un postoperatorio prolongado. Muchas de estas técnicas presentan ventajas y también desventajas que deben ser tomadas en cuenta al momento de planear el tratamiento.…”

RESUMENLa pigmentación melánica es una característica de la encía que podría ser considerada como antiestética; tanto por el profesional como por el paciente. Uno de los tratamientos que ha demostrado mayor efectividad es la despigmentación mediante el uso del láser; sin embargo, su alto costo limita el acceso en algunos estratos sociales, por ello, se emplean otros métodos, tales como: la abrasión con fresas diamantadas, la criocirugía y la electrocirugía. Otra alternativa es el uso del nitrato de plata que actúa produciendo coagulación del epitelio, edema y desnaturalización de proteínas; permitiendo una regeneración óptima del epitelio y logrando una estética gingival adecuada. Se presenta un reporte de caso con el uso de esta técnica y su posterior control por periodos hasta los 18 meses post tratamiento.
