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.

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.

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.

Abstract Vitiligo is a disease that causes the loss of skin color in patches due to loss of melanin pigmentation of specific areas of the skin. Although several hypotheses have been proposed, the leading theory is still the auto-immune etiology linked to specific genetic mutations. Vitiligo can also be associated with several autoimmune diseases. There is no curative treatment for vitiligo but, several treatment modalities are considered. Topical therapies like steroids and Calcineurin inhibitors are of popular use in clinical settings also, steroids can be administered systemically in vitiligo patients. Physical therapies as fractionated CO2 (Fr: CO2) laser and Narrowband-UV (NBUV) phototherapy represent a gold standard in treatment in clinical practice. Moreover, intralesional therapies are emerging, one of which is autologous platelet-rich plasma injection. Aim of the study This study aimed to evaluate and compare the efficacy and safety of Fr: CO2 laser, PRP, combined Fr: CO2 laser and PRP, combined Fr: CO2 laser and NB-UVB, combined Fr: CO2 laser, PRP and NB-UVB in the treatment of vitiligo as well as reporting the side effects. Patients and methods This study included 20 vitiligo patients with at least 6 patches of stable vitiligo (120 patches), the patches were divided into six groups according to the treatment modality. Assessment of treatment response was done through patient satisfaction score and Vitiligo analysis by computer-assisted grid (VACAG). Results Regarding surface area reduction in included patients, fractional CO2 laser achieved the best results followed by triple combination therapy (CO2 with PRP and NB-UVB), the least response was with CO2 with PRP treatment. Patient satisfaction in the current study had a different outcome, PRP treated patients exhibited the highest satisfaction scores while triple combination treated group showed the least satisfaction scores.

Oral melanin pigmentation is a ubiquitous presentation in the oral cavity. It could be a cause of psychological distress to many subjects due to aesthetic reasons. Aims and Objectives: This study attempts to compare the laser and scalpel depigmentation techniques. It also includes a comparison related to the Visual Analog Scale, patient comfort, healing response and time taken for the procedure and recurrence of pigmentation. Materials and Methods: A total of 10 patients were included in the study. A split-mouth approach comparing the scalpel technique with that of the diode laser technique was planned. Results and Conclusion: The results of the present study revealed that both laser and scalpel techniques are equally effective for depigmentation, yielding aesthetic results.

Wound dressings can accelerate wound healing. The degradable polymer poly(lactic acid) (PLA) shows good mechanical properties and biocompatibility. Sodium alginate (SA) holds good biocompatibility, hemostasis, and high hygroscopicity. Poly(vinyl alcohol) (PVA) has good spinnability as a pharmaceutical excipient. Herein, we carried out a comparison study of electrospun PLA and PLA/PVA/SA fiber membranes for wound healing in vitro and in vivo. In this study, PLA and PLA/PVA/SA nanofiber membranes were fabricated through electrospinning to produce a highly porous and large specific surface area that could promote wound healing. In vitro experiments showed that PLA and PLA/PVA/SA nanofiber membranes could all provide good support for the growth of rat fibroblasts (L929). Moreover, rat fibroblasts displayed slightly better adhesion and proliferation on PLA/PVA/SA than on the PLA fiber membranes. The in vivo potentiality of the PLA and PLA/PVA/SA fiber membranes was assessed in rat models of skin defects in which the PLA and PLA/PVA/SA fiber membranes significantly improved wound healing compared to commercially available gauzes. No significant differences in wound healing were observed between PLA and PLA/PVA/SA fiber membranes in our study. Furthermore, Masson staining and PCR displayed the PLA fiber membrane promoted protein deposition compared to the PLA/PVA/SA fiber membrane. In addition, IHC suggested that PLA/PVA/SA dressing reduced the inflammatory response during early wound healing compared to the PLA fiber membrane. These findings highlight the utility of fiber membranes as novel wound-healing dressings.

Studies of patient satisfaction are continually needed to provide feedback to the medical community about rapidly changing telemedicine technology. We accumulated data during 1998 from geriatric patients living in a retirement community based on their experience with telemedicine (one encounter a week for eight weeks). Responses to the items on a Likert scale were generally positive. A similar study was conducted with random patients at the same site two and a half years later. The results were once again positive and appeared to show an even better response than those obtained in the previous study. Thus, although the pilot study was small (20 patients, 18 reporting), this trend may reflect an increased acceptance of telemedicine applications among geriatric patients. Larger studies are needed to substantiate this claim.

<p>The purposes of this research are to know the effect of <em>C.pubescens</em> fruit extract on the amount of gingival fibroblasts in wound healing of <em>Rattus </em><em>norvegicus</em> mouth cavity’s mucosal and to know the effect of <em>C.pubescens</em> comes from two different areas (Dieng and Cangar) on the amount of gingival fibroblasts in wound healing of <em>Rattus</em><em> norvegicus</em> oral mucosa. Twenty eight rats are divided to be four groups (K1, K2, K3, and K4), each rat is wounded 1 cm on the gingival mucosa of lower jaw (specifically on the apical region of incisive teeth). K1 is the control group with aquadest treatment on the wound. The wound in the K2 is treated with <em>C.pubescens </em>fruit extract from Dieng. The wound in the K3 is treated with <em>C.pubescens </em>fruit extract from Cangar. And the treatment for K4 is medicated by policresulen (common medicine for oral mucosal wound). On the fifth day of the treatment, all rats are sacrificed, and the gingival tissue is taken up for the next step. Gingival tissue is smeared by Haematoxylin Eosin (HE) to analyze the amount of gingival fibroblasts histologically. The result of this research shows that the highest average amount of gingival fibroblasts comes from K4 (policresulen treatment). And there is no significant difference on the number of <em>Rattus norvegicus</em> gingival fibroblasts from all of the groups (K1, K2, K3, and K4).</p><p> </p><p><strong>Keywords</strong>: <em>fibroblast, gingival, wound, mucosa, mouth, C.pubescens</em></p>
