Filter by:Gingiva being the most frequently pigmented tissue of the oral cavity challenges a lot of people with an esthetic concern. Increased production of melanin, a pigment produced by the melanocytes present in the basal and suprabasal cell layers of the epithelium leads to the hyper-pigmented appearance. Over the decades many non-surgical as well as surgical techniques have been developed to manage the melanin induced hyper-pigmentation of gingival tissue with comparable efficacies. Till date, the most common gingival depigmentation procedure with satisfactory results remains the conventional scalpel (#15 blade) method. Nowadays, minimally traumatising the surgical field and gaining maximum outputs with help of microscopy and microsurgical instruments has attained a level of utmost importance in surgical procedures including periodontal therapy. Improved results in terms of increased vascularization of the grafts, relatively better percentages of root coverage a significant increase in width and thickness of keratinized tissue, an improved esthetic outcome and decreased patient morbidity in cases of gingival recession treated via microsurgical approach have been observed and well documented. However, perusal of the literature available suggests that clinical outcomes and esthetic potential of the results of gingival depigmentation using principles of microsurgery is an area of interest that still needs to be explored further. This study is therefore aimed at evaluating and comparing the clinical, esthetic and patient-related outcomes of gingival depigmentation performed using microsurgery vs conventional surgical technique.
Gingiva being the most frequently pigmented tissue of the oral cavity challenges a lot of people with an esthetic concern. Increased production of melanin, a pigment produced by the melanocytes present in the basal and suprabasal cell layers of the epithelium leads to the hyper-pigmented appearance of these tissues. Over the decades many non-surgical as well as surgical techniques have been developed to remove the melanin induced hyper-pigmentation of gingival tissue with comparable efficacies. The surgical treatment modalities include use of scalpel, laser ablation, bur abrasion, electrocautery, cryosurgery, radio-surgery, free gingival grafts and acellular dermal matrix allograft etc. Diode lasers have frequently been used in a variety of soft tissue surgical procedures and have many advantages such as less pain, bleeding, scar formation and infection. Examined histologically, laser wounds have been resulted in less wound contracture or scarring, and ultimately improved healing. Depigmentation with lasers has become popular in recent times due to good results but requires sophisticated equipment and occupies a large space. Therefore the most practical gingival depigmentation procedure, both patient and operator wise, with satisfactory results remains the conventional scalpel (#15 blade) method. Nowadays, minimally traumatising the surgical field and gaining maximum outputs with help of microscopy and microsurgical instruments has attained a level of utmost importance in surgical procedures including periodontal therapy.

The study is a randomized controlled clinical trial comparing the use of microneedling with vitamin C against injecting vitamin C for depigmentation in physiological gingival melanin hyperpigmentation in a group of patients attending the outpatient clinic of the department of Oral Medicine and Periodontology-Cairo University.
This observational cross-sectional study aims at determining the prevalence of gingival pigmentation among a sample of adult Egyptian patients attending the diagnostic centre at Faculty of Dentistry, Cairo University and identifying its association with other risk factors.
AIM: To evaluate the association of the levels of blood haemoglobin to the distribution and severity of gingival melanin pigmentation at 3 different periodontal health status SAMPLE SIZE ESTIMATION - Done using GPower v.3.1.9.2 - Total sample size = 60 (20 each in 3 groups) - Effect size = 40% - Power = 80% - α-error = 5% SAMPLING: - Simple random sampling - Subjects to be recruited from out patient pool of KLE Society's Institute of Dental Sciences, Bangalore - Subjects to be categorised into 3 groups (20 subjects each) 1. Group A - Healthy periodontium 2. Group B - Gingivitis 3. Group C - Periodontitis PARAMETERS ASSESSED - Blood Haemoglobin Concentration (in %gm/dL) - Hedin Melanin Index Score 0: No pigmentation Score 1: one or two solitary unit(s) of pigmentation in papillary gingiva without formation of a continuous ribbon between solitary units Score 2: More than three units of pigmentation in papillary gingiva without the formation of a continuous ribbons of pigmentation Score 3: One or more short continuous ribbons of pigmentation Score 4: One continuous ribbon including the entire area between canines STATISTICAL ANALYSIS - SPSS for Windows Version 22.0 to be used - Descriptive statistics: It includes expression of study parameters in terms of Mean & SD for continuous variables, whereas in terms of frequency and proportions for categorical variables. - Inferential Statistics: Chi Square Test will be used to compare the pigmentation index between 03 groups. And similarly, gender wise comparison of hemoglobin concentration will be done using the same test. One-way ANOVA test followed by Tukey's HSD post hoc Analysis will be used to compare the mean hemoglobin levels based on the pigmentation index scores in each group. The level of significance [P-Value] was set at P<0.05
