AI Article Synopsis
- Gingival color significantly impacts smile aesthetics, with hyperpigmentation leading to unesthetic appearances, especially in individuals with a gummy smile. This study aims to evaluate the efficacy of carbon dioxide (CO) laser treatment for gingival hyperpigmentation.
- Conducted in Vietnam with 38 patients, the study used assessments like Ponnaiyan classification and the Hedin melanin index to measure pigmentation and evaluated pain levels during treatment with the Visual Analog Scale (VAS).
- Results indicated that CO laser treatment resulted in minimal pain and 100% complete epithelization within a week, with high rates of improvement in pigmentation scores after 12 weeks, confirming it as a safe and effective treatment option.
Article Abstract
Background: Smile aesthetics has a vital role to play in an individual's life and one of the factors affecting the beauty of the smile is gingival color. A gingival color change or gingival hyperpigmentation causes an unesthetic smile line, especially in patients with a gummy smile, which is also known as a black gummy smile. Numerous gingival depigmentation methods have been performed successfully for ablating gingival melanin pigmented epithelium. Thus, the aim of this study is to evaluate the treatment efficacy of gingival hyperpigmentation by using a carbon dioxide (CO) laser.
Methods: A cross-sectional descriptive study was carried out with 38 patients at a hospital in Vietnam. Ponnaiyan classification and the Hedin melanin index were used to assess the distribution and extent of gingival pigmentation in the study. Pain assessment was performed using the Visual Analog Scale (VAS) to evaluate the intensity of pain during the laser treatment. In addition, clinical evaluation (i.e., wound healing) of each treatment procedure was conducted using the three level Dummett-Gupta Oral Pigmentation Index (DOPI) assessment.
Results: This study showed that less pain was experienced by patients treated by CO laser; the rates of no pain, mild pain and moderate pain after treatment were, respectively, 21%, 76% and 2.6%; there was 100% complete epithelization after 1 week. The DOPI rates for turning from a DOPI score of 1, 2 or 3 to a DOPI score of 0 after a 12-week treatment were 87.5%, 76.9% and 24%, respectively.
Conclusions: Using a CO laser for gingival melanin pigmentation treatment is a safe and effective procedure.

Gingival depigmentation with the help of lasers is known as an effective technique. The aim of this study was to compare the efficiency of 980nm diode and CO2 lasers in the treatment of gingival hyperpigmentation. In this clinical trial study, 14 individuals (8 females and 6 males) with the age range of 19 to 47 years were selected.

Background: Recurrence of gingival pigmentation following depigmentation procedures is common, raising the question of the influence of an underlying cause, if any. Melanin, a non-hemoglobin-derived brown pigment, is the most common endogenous pigment contributing to gingival pigmentation. Hemoglobin derivatives are among the other prime pigments that contribute to gingival color.

Gingival hyperpigmentation is a condition wherein there is excessive deposition of melanin pigment, which is produced by the melanocytes of the gingiva. Gingival depigmentation is a periodontal surgical procedure whereby the pigmentation is removed or reduced by various surgical techniques that are associated with significant postoperative pain, bleeding, and recurrence. Laser ablation has been recognized as one of the minimally invasive, effective, comfortable, and reliable techniques for gingival depigmentation.

The color of the gingiva is determined by the degree of vascularization, epithelial thickness, and the number of melanin pigments within the epithelium. Melanin pigmentation is caused by abnormal or increased deposition of melanin by active melanocytes located mainly in the basal and supra-basal cell layers of the oral epithelium. Oral melanin pigmentation occurs most frequently in the gingiva, known as gingival hyperpigmentation (GHP), which is a common esthetical concern with variable etiologic factors.

Diode lasers are one of the most widely used modalities in soft tissue dental surgery. Recent advancements have expanded the clinically useful emission spectrum of diode lasers to include the blue light region, corresponding to wavelengths such as 445 and 450 nm. The melanin present in hyperpigmented gingiva acts as a chromophore and absorbs laser energy, thus facilitating the denaturing of melanin-containing cells in the gingiva.
