Gingival Depigmentation

Aim of the Study. This study aimed to compare the effectiveness of diode laser (980 nm) and erbium-YAG laser (2940 nm) for gum depigmentation. Background. Gingival hyperpigmentation, “black gum,” refers to black discrete single or multiple pigments on the gingiva. Several factors may play a role in gingival hyperpigmentation ranging from physiologic pigmentation to manifestations of systemic diseases. Several techniques have been used for gingival depigmentation to lighten its color. Methods. Fifteen patients exhibiting nonsmoking melanin hyperpigmentation, with the mean age of 28.6 ± 7.8 years, were recruited. The facial gingiva of the anterior teeth and premolars of each jaw was divided into two halves. The right or left side of each jaw quadrant randomly received either diode laser operating at 980 nm wavelength or erbium-YAG laser at 2940 nm. Parameters such as degree of gingival depigmentation, bleeding, pain, patient satisfaction, and wound healing were assessed and compared between the two techniques. The subjects were followed up to six months for melanin pigmentation recurrence. Results. Both techniques were efficient for gingival depigmentation. Nevertheless, bleeding during surgery was statistically higher for Er:YAG laser technique as compared to diode laser. Wound healing showed statistically nonsignificant differences between the two lasers, although Er:YAG seems to give better outcomes than the diode. The patients were satisfied with both laser techniques during and after gingival depigmentation. However, the pain score was higher for Er:YAG laser than for diode laser. Conclusion. This study demonstrated that both lasers’ techniques are efficient for gingival depigmentation. However, diode laser seems to show less painful experience and relatively better bleeding control.

AbstractGingival melanin pigmentation occurs in all races in variable amount caused by melanin granules. The degree of pigmentation varies from person to person. Excessive gingival pigmentation may be a major esthetic concern for many patients. Methods of deepithelialization of the pigmented or discolored areas of gingiva using different methods such as scalpel method, bur method or laser method are well documented. The procedure for all three techniques has been described and evaluated here. Following presentation encloses a case series in which depigmentation of upper anterior gingival was carried out. The case presented with moderate to severe pigmented gingival (DOPI score ≥ 3) which were treated with one of the above mentioned techniques. The results of these cases suggested that ablation of the gingiva by a Diode laser, abrasion with a scalpel or rotary round bur is good enough to achieve esthetic satisfaction and fair wound healing without infection or severe pain.

Gingival Depigmentation

<p>Excessive gingival pigmentation is a major aesthetic concern in modern society, though it is not a medical problem they consider it as a negative attribute. Patients with gingival hyperpigmentation usually complain and request cosmetic therapy, particularly if the pigmentation is visible during speaking and smiling. Various depigmentation methods, including burr abrasion, cryosurgery, electro-surgery, split thickness flap excision and surgical scraping techniques have been used with varying degrees of success. Recently, lasers have been used to ablate cells containing and producing the melanin pigment. The present study was undertaken to compare the clinical effectiveness and patient comfort of surgical scrapping and diode laser technique used for gingival depigmentation for a follow up period of 6 months.20 subjects participated in this split mouth study. The clinical evaluation parameters included Extent and Intensity of gingival hyperpigmentation, post-operative gingival bleeding and pain. On follow up examination at 6<sup>th</sup> month there was no statistical difference in repigmentation extent and intensity between diode laser and surgical scraping techniques. The mean pain scores for treated sites with diode laser were significantly lower than surgical scrapping technique at 24 hours (t-value=2.430, p-value=0.02). The postoperative gingival bleeding at end of procedure was significantly lower with diode laser than surgical scrapping technique (p-value=&lt;0.0001). There was no statistical difference in postoperative re-pigmentation and clinical efficacy among the subjects between surgical scraping and diode laser technique at 6<sup>th</sup> month follow up. Diode laser technique provides better haemostasis and good visibility at the surgical site. The post-operative patient comfort is better at the surgical sites treated with diode laser than surgical scrapping method. Hence, both the techniques are used for depigmentation procedures depending on the severity and gingival biotype and patient acceptance.</p>

ABSTRACT Gingival hyperpigmentation are major concerns for a large number of patients visiting the dentist. Melanin hyperpigmentation usually does not present a medical problem, but patients usually complain of dark gums as unesthetic. Pigmentation of gingiva is commonly caused by deposition of melanin in the basal layer of oral epithelium. Gingival melanin pigmentation may be seen across all the races and at any age without gender predilection. This case report describes the application of semi conductor diode laser procedure for gingival depigmentation. How to cite this article Saini R, Pazinatto FB, Radnai M.

Gingival hyperpigmentation in many esthetic concern patient poses a psychological problem and embarrassment. Among the many procedures used for gingival depigmentation, diode laser is considered as one which is highly accepted by the patient due to the absence of bleeding during and after procedure and being a fast and effective method. Literature have also stated the beneficial effect of low dose laser therapy on wound healing due to its potential to increase mitochondrial function, adenosine triphosphate (ATP), RNA, and protein synthesis which may further increase the cellular metabolism resulting in enhancement in wound healing and acceleration of the inflammatory process. This case report presents the use of diode laser for gingival depigmentation followed by laser photobiomodulation in an attempt to fasten the healing.

ABSTRACT The complaint of black gums is common particularly in patients having a very high smile line and possess esthetic problems for them. The degree of gingival pigmentation depends on melanoblastic activity. Various treatment options are in practice for depigmentation which includes scalpel gingivectomy, free gingival graft surgery, use of chemicals, such as 90% phenol and 95% alcohol, bur abrasion, electrosurgery, cryosurgery and lasers. Among the various techniques lasers offer a promising therapeutic option since it is simple, painless and predictable. Laser has been recognized as the most effective and reliable technique having many advantages as compared to other conventional treatment modalities. It provides a bloodless and painless surgery. Here, we report gingival depigmentation of 21-year-old female patient using scalpel and laser technique. How to cite this article Bhardwaj A, Grover HS, Lal S.

Gingival Depigmentation

The normal appearance of the gingiva is pink to light red, and this appearance may change due to many factors and might be noticeable causing aesthetic concerns. In the Gulf area, the gingival melanin pigmentation is of the main type of concern, and patients expect the pigmentation to be removed for aesthetic reasons. Many techniques have been used to remove the melanin pigmentation such as using surgical blades, diamond or ceramic burs, chemicals, and lasers. This study is comparing the results of three lasers (Er, Cr, YSGG 2780 nm, Diode 940 nm, and 445 nm) in the removal of melanin gingival depigmentation. Clinical outcome parameters including bleeding, wound healing, pain, duration of procedure, color improvement, patient satisfaction, and relapse rate after 2 years were assessed. Conclusion. Within the limitation of this study, all three wavelengths were fast, effective in peeling the pigmentations and well tolerated by the patients. The esthetical results were excellent, and the patients were highly satisfied. Suggestion. To have a bigger number of samples in future papers, and histological studies might be included to explore the different impacts of each wavelength on the gingival melanin pigmentation specifically and on the gingival tissue generally.

Purpose: The goal of this study is to compare the scalpel and diode laser methods for treating gingival hyperpigmentation in terms of postoperative discomfort and wound healing. Materials & Methods: Sixteen systemically healthy individuals diagnosed with light or moderate gingival hyperpigmentation were enrolled for this study. Patients were randomly assigned to one of two treatment groups: scalpel or laser. Dummett’s oral pigmentation index was recorded at baseline. Early wound healing and post-operative discomfort were evaluated on the 7th day by using the VAS form. Comparisons between the groups were tested using the Mann-Whitney U test and P-value < 0.05 was considered significant. Results: Total epithelization was observed in the laser group, whereas the epithelization was incomplete in the scalpel group at the end of the observation period. The pain perception on the first two days after the surgery was significantly higher in the scalpel group than in the laser group. (p=0,002 and p=0,038, respectively). No significant differences were found between the fourth- and seventh-day when surgical techniques were compared regarding pain perception (p>0,05). Similarly, pain perceptions of female and male individuals showed no significant difference (p>0,05). Conclusion: In the treatment of gingival hyperpigmentation, both surgical techniques were clinically successful. Although the treatment process was long, according to the results of our study, the laser technique is superior to the scalpel method in terms of patient comfort. The choice of the method may vary depending on the available equipment and the clinician’s preference or request of the patient.
