ABSTRACT Background Gingival melanin pigmentation often occurs as the result of abnormal deposition of melanin. Melanin pigmentation is completely benign and presents no medical problem. However, patients complain the esthetic problem as ‘Black Gum’. The aim of this study was to compare the effectiveness of depigmentation by Er:YAG laser and cryosurgery. Materials and methods This study included 20 patients with gingival pigmentation of maxillary incisors, aged 15 to 44 years. Excluding criteria were smoking, systemic disease and pregnancy. Patients treated randomized split mouth, with Er:YAG laser (Pd: 120 mj, RR:12 Hz) along with water spraying of half of maxillary gingivae and on the opposite side cryosurgery was done under topical anesthesia. Patients were followed up at 1, 2, 4 weeks and 3, 6, 12 months after treatment. Results Healing was uneventful follow-up period for 6 to 12 months showed no repigmentation in none of them. Slight erythema was observed. No postoperative swelling, hemorrhage, pain, infection were reported. Conclusion Depigmentation of gingival melanin hyperpigmentation by cryosurgery and Er: YAG laser radiations were found to be an effective procedures. Postoperative patient's satisfaction were impressive. How to cite this article Farahmand A, Moghareh Abed A, Mansouri Y.

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.

Background: To present the benefits of high power lasers (Er: YAG and Nd: YAG) over the use of the high speed turbine for the extraction of ceramics restorations, without damaging the surfaces of the teeth; being a relatively easier and faster procedure without the use of anesthetic agents, and the preparation of the ceramic restorations and cementing in the single session; with a follow-up of 1 year. Objective: The benefits of lasers over high-speed turbine mechanical instrumentation for crown removal encompass efficient restoration recovery without damage to tooth surfaces; and a relatively easier and faster procedure without the use of anesthetic agents. Methods: The Er: YAG laser (no contact; 3.2-4.0 W, 20 Hz) was used to extract the porcelain prosthesis, followed by a gingivectomy with the Nd: YAG laser on tooth 12 to improve the gingival contour. The dental surfaces where the ceramic prosthesis will be cemented were scanned. Then, CAD / CAM technology was used to make the ceramic veneers that were cemented in the same session. Results: The efficacy the Er:YAG laser energy was observed by the decreased of the time to remove all-ceramic materials through ablation of bonding cements, reducing working time by 75% compared to a high-speed turbine. Conclusions: An Er: YAG laser can safely remove lithium disilicate crowns with the settings used in this study. Laser-assisted removal of all ceramic PDFs is a promising treatment protocol. The use of the Nd: YAG (2.0 W power, short 20Hz, 320 µm optical fiber, in contact) laser allowed gingivoplasty to be performed, automatically cauterizing avoiding post-operative bleeding, and facilitating the preparation of ceramic restorations the same day. The use of high-power lasers and the use of accompanying CAD / CAM technology allowed this clinical case to be completed in a single visit without the use of temporary restorations, achieving absolute patient satisfaction.   Keywords Er:YAG; Nd:YAG; Lithium disilicate ceramic; CAD/CAM.

ABSTRACTBackground : Gingival enlargement, a terminology for an increase in the size of the gingiva, is a general feature of gingival dis­eases. Gingival melanin pigmentation does not present a medical problem, but is likely to generate a concern in aesthetic function. Although melanin pigmentation is not a chief complain, this condition still need to be corrected. Clinicians are often confronted with a challenge in achieving gingival esthetics. Purpose : This case report aims to explain how to achieve esthetical and functional demands in gingival enlargement and gingival hyperpigmentation case with gingivectomy and gingival depigmentation. Case: This surgical procedure aim to retain esthetical and functional demands. Case Management: An 18-years-old male presenting with maxillary chronic inflam­matory gingival enlargement associated with prolonged orth­odontic therapy is reported. Orthodontic appliances are factors for irritation and plaque retention that interfere oral hygiene and regulate gingival inflammation. Surgical therapy was performed to provide a better aesthetic outcome and prevent plaque retention. Conclusion: The combination of gingivectomy and gingival depigmentation can resolve gingival enlargement and gingival hyperpigmentation perfectly with close proximity to the ideal gingival condition.Keyword : Gingival depigmentation, Gingivectomy, Orthodontic

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.

Premature loss of teeth in children leads to space loss and affects arch integrity. The band and loop space maintainer is used in majority of patients requiring single tooth space maintenance in both primary and mixed dentitions. It preserves the proximal dimensions, but it is nonfunctional. This paper describes a method to modify the conventional band and loop space maintainer into a functional one and reports its clinical application and follow-up in five children.

Background:IgA vasculitis (IgAV) could be limited to skin or evolve into a systemic disease, affecting characteristically joints, gastrointestinal tract and/or kidneys.Objectives:We aimed to look for differences between adult IgAV patients with disease limited to skin compared to systemic IgAV.Methods:Medical records of histologically proven adult IgAV cases, diagnosed between January 2010 and December 2020 at our secondary/tertiary rheumatology centre were analyzed.Results:During the 132-month observation period we identified 328 new IgAV cases (59.5% males, median (IQR) age 64.3 (45.1; 76.1) years). Ninety-four (40.2%) patients had skin limited disease, and the rest systemic IgAV.Clinical differences between skin limited and systemic adult IgAV are presented in table 1. Adults with IgAV limited to skin were significantly older, had less commonly skin lesions above the waistline and a lower level of C reactive protein compared to patients with a systemic disease. There were no differences in the frequency of skin necroses between the compared IgAV subgroups. The frequency of potential vasculitis triggers (prior infections, new medications, malignancy) was similar between the compared subgroups.Table 1.Clinical characteristics of IgA vasculitis patients with skin limited and systemic diseaseClinical characteristicsSkin limited IgAV (94)Systemic IgAV (234)P valueMale gender (%)54.361.50.263Age (years)*68.0 (55.0-80.5)61.5 (41.7-75.8)0.007Current smoker (%)13.821.80.123Antecedent infection (%)28.733.80.434New medication23.423.51.0History of cancer12.810.70.569Symptom duration (days)*7 (5-21)8 (5-14)0.756Purpura above waistline36.255.60.002Skin necroses (%)52.145.70.329ESR /mm/h) *32 (18-52)34 (17-53)0.873CRP (g/l) *13.5 (1-32)30 (11-68)<0.001Elevated serum IgA (%)50.649.10.892Legend: * median and IQR;Follow up data were available for 250 (76.2%) patients.

Lipofilling is a popular technique to treat volume loss in aging patients. The isolated adipose tissue is composed of adipocytes and stromal vascular fraction cells, which include adipose-derived stem cells (ASC). We hypothesize that the patient’s wrinkle severity scale (WSS) and patient’s satisfaction on the global aesthetic improvement scale (GAIS) can be improved after using concentrated lipoaspirate. Fourteen patients (54 years ± 11.09 years) with volume loss in the midface area underwent waterjet-assisted liposuction (Human Med AG, Schwerin, Germany). Fat was centrifuged in an ACP Double Syringe (Arthrex GmbH, Munich, Germany) using Rotofix 32A centrifuge (Andreas Hettich, GmbH & Co.KG, Tuttlingen, Germany). Homogenization was performed using the double syringe and a 1.4 mm female–female luerlock connector. After a second centrifugation, patients received periorbital (PO) and nasolabial (NL) lipografting. ASC count was performed after enzymatical digestion. Vitality of cells was assessed using a resazurin assay. During long-term follow up (12 months, n = 10), we found a high patient’s satisfaction (GAIS 1+/−0.52) and a good improvement of the WSS during short- and long-term follow-up. The ASC count of processed lipoaspirate was 2.1-fold higher than of unprocessed lipoaspirate (p < 0.001). The difference of ASC in sedimented and simply centrifuged lipoaspirate was also significant (p < 0.05). Facial rejuvenation with concentrated fat graft offers good results concerning objective aesthetic outcome and patient’s satisfaction.

Objective. This study was aimed at assessing the long-term ocular control of adalimumab (ADA) in a large real-world population with noninfectious primary or secondary uveitis, focusing on the steroid-sparing effect and on disease-modifying antirheumatic drug (DMARD) cotreatment. Methods. In this retrospective, multicenter study, the efficacy of ADA was evaluated in terms of ocular control, changes in best-corrected visual acuity (BCVA), corticosteroid-sparing effect, and drug retention rate, overall and stratified according to DMARD cotreatment. Results. 106 patients were included. 88.7% had an associated systemic disease. After 6 and 12 months, proportions of patients with effective ocular control were 83.7% and 83.3%, respectively. At last the follow-up, 94.6% of patients had satisfactory ocular control. No difference in terms of ocular control at all time points emerged among patients starting ADA for ocular vs. systemic involvements. Patients with poor baseline BCVA remained stable or improved, while those with good BCVA hardly worsened. At 6 and 12 months, the median dose of prednisone significantly reduced to 5 mg/day (0-5) and 2.5 mg/day (0-5) (p<0.001). Over a median follow-up of 36 months, 38 subjects discontinued ADA treatment. Mild to moderate side effects were reported in 7 patients (6.6%). ADA ocular control, corticosteroid-sparing effect, and drug retention rate were not influenced by the concomitant use of DMARDs. Conclusion. The long-term ocular control of ADA in noninfectious primary or secondary uveitis is confirmed, also for BCVA preservation. Concomitant use of DMARDs does not provide additional benefits to ADA alone in terms of ocular control, steroid spare, and drug retention rate.

AbstractAmyloidosis is a group of idiopathic clinical syndromes caused by the deposition of insoluble fibrillar proteins (amyloid) in the extracellular matrix of organs and tissues. These deposits disrupt the function of the target organ. Amyloidosis can manifest as a systemic disease or a single-organ involvement (local form). Its etiology still remains unclear. Deposits of amyloid in the larynx are rare, accounting for between 0.2 and 1.2% of benign tumors of the larynx. In this retrospective study, we report the clinical aspects, diagnosis, treatment and follow-up of five female patients with localized laryngeal amyloidosis without systemic involvement. The patients were all treated successfully using microlaryngoscopy with CO2 laser or cold instruments. Prognosis is excellent; however, appropriate follow-up is an important part of the long-term management of this disease in order to prevent and control the possibility of local recurrence.
