Background: Juvenile Xanthogranuloma (JXG) is a non-hereditary, self-limiting disease which is usually presented in infancy or early childhood and in males over females., Case Presentation: We report a rare case of oral Juvenile Xanthogranuloma with recurrent progressive gingival hyperplasia and concomitant presentation of osteolysis in a 21-year-old adult male with no significant medical history. Patient presented with generalized gingival hyperplasia, osteolysis of the maxilla and mandible, and a round, firm, nodular mass with clear circumference on the left shoulder. Results of gingival tissue biopsy, karyotype, bone marrow biopsy and immunohistochemistry were suggestive of a diagnosis of Juvenile Xanthogranuloma with no association to hematologic malignancy. Unfortunately, patient declined treatment and elected to be transferred back to local hospital for future evaluation., Conclusions: Juvenile Xanthogranuloma in adults can have atypical manifestations including generalized gingival hyperplasia and osteolysis of the maxilla and mandible. It should be differentiated between Langerhans cell histiocytosis, Papillon-Lefevre Syndrome, and Pyogenic Granulomas. Despite uncommon incidence, it should be included in differential diagnoses in cases of similar clinical presentations., (© 2022. The Author(s).)

An 18-year-old woman presented with enlarged gingivae of 1-year duration with no history of drug consumption or systemic conditions that might explain the enlargement. Biopsy revealed hyperplastic gingival epithelium and a plasma cell-rich inflammatory infiltrate in the subepithelial connective tissue with the presence of scattered multinucleated giant cells. Immunostaining revealed the plasma cells to be positive for IgG4. Serum IgG4 levels were elevated at 3.6 g/L (reference range: 0.049-1.985). These findings led towards the diagnosis of an IgG4-related disease (RD). Other granulomatous conditions were also ruled out via series of investigations. The enlarged tissue was surgically excised. No corticosteroids were administered owing to the localised nature of the manifestations. After 3 months, the gingival size remained unchanged. This case has been reported with a relatively shorter follow-up period because of the rarity of the presentation. IgG4-RD should be considered while diagnosing a patient with gingival enlargement., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Gingival enlargement, although frequently encountered in clinical settings, is rarely associated with systemic diseases or syndromes. Among the diverse pathological conditions of neurofibromatosis type 1 (NF-1), minor manifestations in the orofacial region are occasionally overlooked. Herein, the authors present an unusual case of gingival neurofibroma in a patient with NF-1 associated with characteristic osseous defects in the alveolus in the long-term course of 17 years from the first examination.A 5-year-old boy with NF-1 was referred for the evaluation of gingival enlargement in the posterior left maxilla. An incisal biopsy led to the diagnosis of neurofibroma. At 22 years of age, the patient was referred again with a complaint of bleeding and pain in the same region refractory to periodontal therapy. The gingiva and tuberosity were swollen, and the second molar was affected by the tumor. Radiography revealed a low level of the interdental septum beneath the tumor with a relatively intact periodontal cortical bone, exhibiting a teardrop-shaped bone defect. The lesion was completely resected with the periosteum.Gingival neurofibroma in NF-1 may be associated with osseous and dental abnormalities and can be mistaken for periodontitis. Raising awareness of this clinical entity can lead to proper management of the esthetic and functional problems in the oral and maxillofacial region.

Acute myeloid leukemia is a highly aggressive malignancy with a high morbidity rate, for which an accurate and rapid diagnostic is essential. Acute myeloid leukemia manifestations frequently include oral abnormalities. Still, there is a limited number of studies reporting the incidence of oral manifestations in acute leukemia, the prevalence of periodontal status and periodontal parameters in these patients. Our aim was to emphasize the importance of early recognition by the dental practitioners of oral cavity manifestations as signs of acute myeloid leukemia, so that prompt referral to the hematologists is being done, and appropriate treatment is offered., (Copyright © 2018.

Acute myeloid leukaemia is a myeloid neoplasm with an extremely varying clinical appearance. Skin lesions are common for specific subtypes of acute myeloid leukaemia but are often misinterpreted. Here, we present a case of acute myeloid leukaemia in a young woman exhibiting genital ulcerations and gingival erosions., (© 2018 Medicalhelplines.com Inc and John Wiley & Sons Ltd.)

Background: Many gingival lesions are not induced by plaque. The aim of this study was to analyze the frequency of biopsied non-plaque-induced gingival lesions (NPIGL) in a Chilean population., Methods: One thousand twelve cases of biopsied gingival lesions with confirmed anatomopathologic diagnosis were included, from the records of the Oral Pathology Referral Institute (OPRI), Faculty of Dentistry, University of Chile, between years 1990 and 2009., Results: The most frequent non plaque-induced gingival lesions categories from biopsied cases included hyperplastic lesions, malignancies and benign neoplasms. The most frequent diagnoses in each category were fibrous hyperplasia (35.47%), squamous cell carcinoma (3.85%) and giant cell fibroma (2.08%), respectively. From all lesions, only 8.3% fitted in the specified categories of the current classification of periodontal diseases., Conclusions: The most frequent biopsied NPIGL were hyperplastic lesions and neoplasms. These categories represent relevant lesions to be included in a future periodontal classification system to improve the care needs of the patients, as well as early diagnosis and treatment.

Background and Aims: The CONCERTO study results showing the beneficial effects of conversion from cyclosporine to tacrolimus prolonged-release (tacrolimus PR) in stabilised patients after kidney transplantation, were first published in 2011. This communication describes our first experience of conversion from cyclosporine to tacrolimus PR in stabilised kidney transplant patients. The aim was to determine whether it could be used in routine clinical practice in the Czech and Slovak Republics., Methods: Evaluation was carried out at five transplantation centres in the Czech Republic and Slovakia. In all participating Centres, the drug conversion was conducted according to the ICH/GCP guidelines. A total of 104 patients stabilised after kidney transplantation were converted from maintenance therapy with cyclosporine to treatment with tacrolimus PR. The data were collected 26 weeks after the switch. The primary endpoint was change in kidney graft function measured from the estimated glomerular filtration rate (GFR). The effect of conversion on blood pressure, metabolic parameters and cosmetic changes was also recorded. Special attention was paid to the safety and tolerability of treatment with tacrolimus PR., Results: GFR increased after six months by 10 % (P = 0.040). In addition a significant decrease in serum creatinine and triglycerides level was found together with major reduction in the incidence and severity of gingival hyperplasia and hirsutism. 3% of patients developed new onset of diabetes mellitus. Otherwise, the switch was very well-tolerated, without serious adverse events or acute rejections., Conclusion: Conversion from cyclosporine to tacrolimus PR was shown to be a safe therapeutic alternative with patient benefits.

Background: Sturge-Weber syndrome (SWS) is a rare congenital neurocutaneous disorder. It is characterized by the presence of facial port wine stains, neurological abnormalities like seizures and mental retardation, ocular disorders, oral involvement and leptomeningeal angiomas., Case Report: A 13-year-old boy presented with the chief complaint of swollen, bleeding gums and deposits on the teeth. Detailed medical and dental history, clinical examination and investigations confirmed the diagnosis of Sturge-Weber syndrome. The treatment comprised of a thorough plaque control regimen to reduce the gingival enlargement, and it included oral hygiene instructions, thorough scaling, root planing at regular intervals and plaque index scoring which motivated the patient at each visit., Conclusion: This case illustrates that early intervention in a patient with Sturge-Weber syndrome is quintessential because of its associated gingival vascular features and their complicating manifestations. Furthermore, the need for periodic oral examinations and maintenance of good oral hygiene to prevent any complications from the oral vascular lesions has been highlighted.

During pregnancy periodontal tissues may become more susceptible to internal and external factors promoting inflammation. Changes in hormone levels, alterations in the periodontal tissue structure and a predisposition to dilating blood vessels during pregnancy may lead to a painful inflammation as a response to a slightest amount of biofilm. Tumor gravidarum emerges in 5% of pregnant women during the first or second trimester - it may recede and fade completely right after the labour when hormone levels normalize. This paper explains the aetiology and potential risk factors of pregnancy gingivitis.

Juvenile hyaline fibromatosis (JHF) is a rare progressive autosomal recessive disease that is characterised by papulonodular skin lesions, soft tissue masses, joint contractures, gingival hypertrophy and osteolytic bone lesions. We present an 18-month-old boy with JHF. This case demonstrates that JHF should be considered in the differential diagnosis when multiple subcutaneous nodules are observed in the face, head and neck. Gum hypertrophy with palatal nodules is unusual in JHF., (2015 BMJ Publishing Group Ltd.)

Gingival fibromatosis is a rare, benign, slow progressive fibrous overgrowth of gingiva, with great genetic and clinical heterogeneity. It can be inherited as an isolated trait (hereditary/idiopathic gingival fibromatosis), and/or as a component of a syndrome. We report a case of a young girl suffering from psoriasis who also presented with an unusual generalised idiopathic gingival fibromatosis. Psoriasis, a chronic inflammatory skin disease, of multifactorial origin, is characterised by keratinocyte hyperproliferation, dedifferentiation, neoangiogenesis and inflammation. T cell-mediated immunity is considered to be the key element in the disease process. The existence of oral mucosal alterations in patients with psoriasis is a controversial topic, as histopathological correlations are not clearly evident, and oral and cutaneous lesions do not follow a parallel course. However, this article highlights a possible association of T-lymphocyte stimulation inducing fibroblasts to undergo epidermal hyperproliferation and increased collagen production in the gingiva, which in turn may be responsible for inducing gingival hyperplasia., (2015 BMJ Publishing Group Ltd.)

Background: Plasminogen deficiency is a rare autosomal recessive disease, which is associated with aggressive periodontitis and gingival enlargement. Previously described treatments of plasminogen deficiency associated periodontitis have shown limited success. This is the first case report indicating a successful therapy approach consisting of a non-surgical supra- and subgingival debridement in combination with an adjunctive systemic antibiotic therapy and a strict supportive periodontal regimen over an observation period of 4 years., Case Presentation: The intraoral examination of a 17-year-old Turkish female with severe plasminogen deficiency revealed generalized increased pocket probing depths ranging from 6 to 9 mm, bleeding on probing over 30%, generalized tooth mobility, and gingival hyperplasia. Alveolar bone loss ranged from 30% to 50%. Clinical attachment loss corresponded to pocket probing depths. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, Prevotella intermedia, Prevotella nigrescens and Eikenella corrodens have been detected by realtime polymerase chain reaction. Periodontal treatment consisted of full mouth disinfection and adjunctive systemic administration of amoxicillin (500 mg tid) and metronidazole (400 mg tid). A strict supportive periodontal therapy regimen every three month in terms of supra- and subgingival debridement was rendered. The reported therapy has significantly improved periodontal health and arrested disease progression. Intraoral examination at the end of the observation period 3.5 years after non-surgical periodontal therapy showed generalized decreased pocket probing depths ranging from 1 to 6 mm, bleeding on probing lower 30%, and tooth mobility class I and II. Furthermore, microbiological analysis shows the absence of Porphyromonas gingivalis, Prevotella intermedia and Treponema denticola after therapy., Conclusion: Adjunctive antibiotic treatment may alter the oral microbiome and thus, the inflammatory response of periodontal disease associated to plasminogen deficiency and diminishes the risk of pseudomembrane formation and progressive attachment loss. This case report indicates that patients with plasminogen deficiency may benefit from non-surgical periodontal treatment in combination with an adjunctive antibiotic therapy and a strict supportive periodontal therapy regimen.

Introduction: Gingival enlargement is a common form of periodontal tissue reaction to several irritating factors. The most common form is the drug related gingival hyperplasia--nevertheless the heredity gingival fibromatosis and hematological cases can also occur and might impose a challenge to periodontists. After a short literature summary three Case reports are presented. The first case is a drug related gingival overgrowth in a young kidney transplant women who took Cyclosporin-A. The excessive mass of fibrotic tissue was removed by a series of internal beveled incision and the oral and buccal gingival flaps were united with sutures. The healing was uneventful and during the follow up patient's compliance and oral hygiene was superb. The second case is a very severe antihypertensive drug related gingival overgrowth in a 62 years old man interfering with the closure of his lip and corrected with a combination of conventional gingivectomy and internal reverse beveled incision both and Ca-channel blockers. The third case is a 42 years old woman with chronic idiopathic hemolytic anemia who presented a sudden onset acute excessive generalized gingival enlargement accompanied with severe pain and fever. At admission she was suspect for leukemia. After obtaining biopsy samples and having negative histology the soft tissue mass was removed under general anesthesia with conventional gingivectomy technique, but after a couple of days the severe pain and gingival swelling recurred. With administering systemic corticosteroid therapy (32 mg Medrol), the gingiva healed in five days and the one year follow-up showed a stable hematological and periodontal status. Today the more conservative internal beveled incision is preferred over the conventional gingivectomy in the most cases because it provides a more predictable healing and better esthetics. The recurrence of the drug related gingival hyperplasia can be anticipated by meticulous postoperative individual oral hygiene and regular supportive therapy., Conclusion: The combined conservative and surgical therapy leads to predictable postoperative result even in very severe systematically motivated gingival enlargements, nevertheless the successful patients management needs good cooperation with medical doctors and with the patients themselves.

Case: Haven is an 11-year-old primary care patient who you have followed since her birth. She was the 9 lb 6 oz product of a 38-week gestation complicated by maternal hypertension and seizure disorder treated with tegretol. Her delivery and neonatal course were uneventful. She was diagnosed with austistic disorder at age 2 years, at which time she used no functional language or gestures, had repetitive motor mannerisms, and limited eye contact. She had strong tactile sensory aversions. Her diet was very restricted including only banana yogurt and drinking milk and apple juice for the first several years of life. She was followed by a developmental-behavioral pediatrician approximately annually through age 8 years and then more frequently. She was healthy other than lead exposure (maximum serum level 18 at age 3 years) and multiple febrile seizures with other possible absence episodes. Her development remained very delayed with use of single words and short phrases. She developed multiple repetitive, anxious, obsessive behaviors (picking up lint, organizing, cleaning, and freezing in certain postures) that were treated with a selective serotonin reuptake inhibitors fluvoxamine. Sensory issues were ongoing, with restrictive eating (primarily peanut butter and jelly sandwiches, cereal bars, milk, and a kiwi-strawberry drink). She took a liquid multivitamin until age 8.At age 11 years, 3 weeks prior to admission, Haven developed acute loss of ambulation over the course of 1 day, initially dragging her right leg, and then refusing to walk and her parents brought her in to see you. She had fever, vomiting, and general weakness. She developed extensive bruising over her legs, especially in the popliteal fossae. She was also noted to have friability and dark discoloration of her gums. Initially, you suspected a post-viral syndrome and close monitoring. She was seen twice in the next 2 weeks in a local emergency room where her erythrocyte sedimentation rate was reported to be elevated and juvenile rheumatoid arthritis or a reaction to fluvoxamine were suspected. Antibiotics were also prescribed for gingivitis. She was seen by an orthopedist who felt it was not an orthopedic issue and leg films were unremarkable. With her second emergency room visit, she was transferred to a tertiary medical center and admitted for further evaluation. Where would you go from here?

Purpose: Gingival enlargement, also synonymous with the terms gingival hyperplasia or hypertrophy, is defined as an abnormal overgrowth of gingival tissues. A case of a 19-year-old male presenting with maxillary and mandibular chronic inflammatory gingival enlargement associated with prolonged orthodontic therapy is reported here. Surgical therapy was carried out to provide a good aesthetic outcome. No recurrence was reported at the end of 1 year. The importance of patient motivation and compliance during and after therapy as a critical factor in the success of treatment has also been highlighted through this case report.

Background: A worrying correlation which seems to be overlooked by clinicians is allergic reactions to titanium (Ti) in patients with dental implants., Purpose: The aim of the present review study was to assess whether or not Ti sensitivity is associated with allergic reactions in patients with dental implants., Materials and Methods: To address the focused question "Can Ti cause allergic reactions in patients with dental implants?", databases were explored from 1977 until May 2010 using a combination of the following keywords: "allergy,""dental,""hypersensitivity,""implant,""oral," and "Titanium." Letters to the editor and unpublished data were excluded., Results: Seven studies (six clinical and one experimental) were included. The participants were aged between 14.3 and 84.1 years. In five clinical studies, Ti implants were inserted in the mandible. Five studies reported dermal inflammatory conditions and gingival hyperplasia as allergic reactions in patients with Ti dental implants. A case report presented swelling in submental and labial sulcus and hyperemia of soft tissues in a patient with Ti dental implants. Two studies reported that Ti implants are well tolerated in host tissues. The patch test was performed in two clinical studies for the diagnosis of allergic reactions. Memory lymphocyte immunostimulation assay and lymphocyte transformation tests were also performed., Conclusion: The significance of Ti as a cause of allergic reactions in patients with dental implants remains unproven., (© 2011 Wiley Periodicals, Inc.)

Gingival hyperplasia is a relatively frequent pathologic condition during orthodontic treatment. Oral hygiene can be easily altered in such cases because of additive and irritative effects of orthodontics appliances. So, adequate control of the gingival inflammation is required. The present case reports on a 13-year-old boy who developed, during orthodontic treatment, a gingival hypertrophy that was successfully treated with periodontal surgery consisting on an apically positioned flap procedure. For this purpose, multidisciplinary approach involving orthodontist and periodontist was crucial in the perspective of optimal clinical issues.

Objective: The aim of this follow-up study was to evaluate the long-term outcome of implant-supported or implant-retained mandibular overdenture treatment., Material and Methods: Altogether 112 patients treated with implant-supported overdentures between 1985 and 2004 were invited to the follow-up and 58 attended the clinical examination. The total amount of implants examined and still in use was 197. The average number of implants installed was three (range 2-4), and the mean length of the implants was 12 mm (range 8-21 mm). There were altogether 48 overdentures with a bar connection and 10 with a ball connection., Results: The most frequent prosthetic complications were technical: loosening of the retentive mechanism (39.7%) and breakage of the matrices (5.2%). The most common peri-implant soft-tissue findings were bleeding and slight hyperplasia. The implant-supported overdentures of 19 patients (32.8%) had been renewed, while 39 patients (67.2%) still used their original overdentures, of which the oldest was 20 years old., Conclusion: The results of this long-term follow-up study show that the outcome of implant-supported mandibular overdenture treatment was excellent. The patients were satisfied with the treatment, regardless of the attachment type used. Removable overdentures are more easy to clean and can be cleaned outside the patient's mouth, whereas fixed-implant full-arch dentures in the edentulous mandible require much more time-consuming hygiene. This kind of overdenture treatment is suitable also in the elderly, even though their ability to practice appropriate oral hygiene might be decreased., (© 2012 The Gerodontology Society and John Wiley & Sons A/S.)

Purpose: This report aimed to compare prosthetic aspects and patient satisfaction during a 3-year randomized clinical trial of bar- and implant-retained mandibular overdentures attached with either resilient liners or clips., Materials and Methods: Thirty edentulous male patients (mean age: 62.5 years) received two implants in the anterior mandible after being allocated into two equal groups (according to attachment type received) using balanced randomization. After 3 months, implants were connected with resilient bars. New maxillary complete dentures were then constructed, and mandibular overdentures were retained to the bars with either clips (group I) or silicone resilient liners (group II). Subjects indicated satisfaction with their prostheses using a questionnaire and visual analog scale. Patient satisfaction and prosthetic complications were recorded for both attachments at 6 months and 1 and 3 years after overdenture insertion., Results: Comfort and stability with the maxillary denture and ease of hygiene procedures were rated higher in group II, while ease of handling the dentures was rated higher in group I. No significant differences in other parameters of patient satisfaction between groups were noted after 3 years. The mean number of prosthetic adjustments and repairs in group I (11.9) was significantly higher (P = .00) compared to that in group II (4.8). The most common complication in group I was clip wear, while separation of the resilient liner from the denture base was the most common problem in group II. Hyperplasia under the bar and flabby ridge in the maxilla occurred significantly more often in group I compared to group II., Conclusions: Resilient liner-retained mandibular overdentures had comparable patient satisfaction, less prosthetic maintenance and costs, and less soft tissue complications when compared to clip-retained ones after 3 years.

Crohn's disease (CD) is an inflammatory bowel disease with oral findings, including periodontal manifestations. Anemias, such as iron deficiency and anemia of chronic disease (ACD), are the most common hematologic complications of CD. Periodontitis has systemic effects, and may tend toward anemia, which can be explained by depressed erythropoiesis. In the report presented here, the authors review a case of Crohn's disease diagnosed 10 years previous to the patient presenting with a changing anemic profile and periodontal disease. A discussion of patient and disease management is included.

This case report describes the unilateral acute reduction of vision in the right eye of a 48-year-old woman. The patient was otherwise healthy but 2 days previously had suffered from dizziness and blurred vision. Secondary to this, the patient had already been under dental treatment for 1 week due to gingival swelling. At the first examination a macular branch retinal vein occlusion and Roth spots were found in the right eye by indirect ophthalmoscopy. The immediate diagnostic procedure identified aute amyeloid leukemia (AML) as the cause of the vascular pathology. The AML can be manifested in different ways and the retina is involved in approximately 50% of cases. Due to a secondary hyperviscosity syndrome, which is found in approx. 20% of acute leukaemias, symptomatic central vein occlusion or macular branch vein occlusion can occur. Ophthalmic symptoms can be the first and only signs to be detected. Therefore, ophthalmologists should also consider a systemic disease and initiate a clarification. A differential blood count is indispensable. The results usually improve by a rapidly arranged and suitable therapy. Ophthalmological follow-up examinations are imperative as an initiated chemotherapy can also produce ophthalmological side-effects.

Unlabelled: Aimed at the practitioner in Special Care Dentistry, this is the second article in a two-part series providing guidelines on the dental management of renal patients. Dentists working in Special Care Dentistry will frequently be called upon to manage dialysis patients, whether pre- or post-transplant. The following paper deals with guidance as to the assessment, work-up and management of such patients when undergoing specialist dental treatment. The key to safe treatment is careful assessment, discussion and planning with the relevant team members., Clinical Relevance: This paper provides guidance to the special care dentist for the dental management of patients with renal disease, and highlights issues in patients who are either on dialysis or have a kidney transplant.

Background: Cyclosporin A (CsA) is an immunosuppressant with side effects including gingival hyperplasia. Sarcoidosis is a systemic disease characterized by granulomas. Here, we report on a rare case of sarcoidosis with gingival hyperplasia to clarify whether clinical observation corresponds to in vitro results., Methods: Gingival fibroblasts (HGFs) were isolated from healthy gingiva and cultured with CsA. Total RNA was collected and expression of mRNAs examined using semi-quantitative RT-PCR analysis. Cathepsin B, D, and L expression in overgrown gingiva of the patient was examined by immunohistochemistry., Results: Cathepsin D, L, and vascular endothelial growth factor (VEGF)165 mRNA were markedly suppressed in CsA-treated HGFs, whereas cathepsin B, matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) mRNA were not reduced. Next, the decrease of cathepsin B and L expression in enlarged gingiva was observed, whereas an increase of cathepsin D expression was observed. Clinically, the enlarged gingival lesions were fully resolved by performing oral infection control., Conclusions: Cathepsins regulation might be an important factor in the development of CsA-mediated gingival hyperplasia.

The biologic width includes both the connective tissue attachment and the junctional epithelium and has a mean dimension of approximately 2 mm. Invading the biologic width with a restoration can result in localized crestal bone loss, gingival recession, localized gingival hyperplasia, or a combination of these three. When restoring teeth that have subgingival caries or fractures below the gingival attachment, a clinical crown-lengthening procedure is needed to establish the biologic width. This article presents three case reports that utilized crown-lengthening procedures.

Epulis fissuratum is a pathological condition caused by an ill-fitting denture. The mucogingival hyperplasia may be considered as a reactive condition of the oral mucosa to excessive mechanical pressure on the mucosa. Epulis fissuratum excision is a procedure usually done for prosthodontic reasons. The treatment of this benign entity is essential mainly for masticatory reasons. The use of diode laser for epulis removal without infiltrated anesthesia in a conscious geriatric patient is currently under investigation.

Kidney transplantation is the best option of treatment for patients with end-stage renal failure. However, following kidney transplantation many stomatological abnormalities are frequently reported. It is mainly due to immunosuppressive therapy and subsequent impaired immune response. There is an increased risk of infections and malignancies. The most frequent findings in the oral cavity include: aphthae, erosions of bacterial, viral and fungal origin, lichen-like or leukoplakia-like changes. The another type of change is gingival hyperplasia and its periodontologial consequences. In this review etiology, clinical symptoms of periodontological changes are described together with algorithm of pre- and posttransplant management of oral healthy is provided.

Adverse reactions stemming from the use of fixed and removable orthodontic appliances have been a cause for concern for both orthodontists and researchers in the health care field. Nickel often has been indicated as a biological sensitizer capable of causing short- and long-term reactions (Type IV immune response). This article addresses the clinical and diagnostic aspects of nickel-related reactions in orthodontic patients, based on the literature. A case report highlighting the periodontal, clinical, and histopathologic aspects of an allergic patient in orthodontic treatment is presented.

Purpose: The objective of the present study was to emphasise the oral and dental findings of a male patient with the Maroteaux-Lamy syndrome who successfully underwent bone marrow transplantation (BMT) at the age of 22 months., Case Report: A 15-year-old boy was referred to the Dentistry Division of the Catholic University of Brasília, Brazil, for dental diagnosis. General characteristics of the Maroteaux-Lamy syndrome, such as a large head, a short neck, corneal opacity, an open mouth with macroglossia, enlargement of the skull and a long anteroposterior dimension, were observed. The patient had received the benefit of a BMT at an early stage. Therefore, characteristics were presented in a moderate form, except for the skeletal symptoms., Discussion: Maroteaux-Lamy syndrome, also known as mucopolysaccharidosis type VI, is a lysosomal storage disorder that is caused by a deficiency of arylsulphatase B, which leads to an accumulation of dermatan sulphate in tissues and its increased excretion in urine. The deposition of mucopolysaccharides leads to a progressive disorder involving multiple organs. It is a rare condition that is inherited as an autosomal recessive trait. The characteristic features of this disease include retardation in growth, a large head, a short neck, corneal opacity, typical facies and spinal abnormalities. The main dental findings of this syndrome include gingival hyperplasia, hypertrophy of the maxillary alveolar ridge, macroglossia, unerupted dentition, malocclusions and dentigerous cyst-like follicles. BMT is a therapeutic treatment that is given to permanently replace any disorder caused due to the deficiency of enzymes in patients with storage diseases.

Alport Syndrome (AS) is an important hereditary disorder affecting the glomerular basement membrane. Diagnosis of AS is based on the presence of hematuric nephropathy, renal failure, hearing loss, ocular abnormalities and changes in the glomerular basement membrane of the lamina densa. The aims of this case report were to show the changes in the gingival tissues in a patient with AS under therapy with cyclosporin-A after renal transplantation and to discuss the possible role of type IV collagen in gingival basal lamina as an alternative approach for the diagnosis of AS. A 20-year-old male patient with AS underwent periodontal therapy including a series of gingivectomy surgeries. Gingival samples obtained during the second surgery were examined histopathologically and by transmission electron microscopy for further pathological examination. Gingivectomy procedures have been performed every 6 months over the last 4 years. The excessive and fibrous gingival enlargements resulted in migration of the anterior teeth, but no alveolar bone loss occurred. This is the first report to demonstrate the possible changes in the gingival tissues caused by AS. It is suggested that gingival biopsy can be an initial diagnostic tool instead of renal or skin biopsies. Proper dental and periodontal care and regular visits to the dentist could provide limited gingival hyperplasia to patients with AS.

Objective: To determine the prevalence of nickel allergy in a sample of orthodontic patients and longitudinally compare the clinical periodontal status of these individuals with that of a group of nonallergic patients., Materials and Methods: The initial sample consisted of 96 patients selected randomly from a databank of patients who sought orthodontic care at a teaching institution. Following the selection and beginning of treatment, periodontal status was assessed over a 12-month period (one evaluation every 3 months-T(1), T(2,) T(3,) T(4)) using the Loe index. The evaluations were performed blindly by a single, calibrated examiner and were followed by prophylaxis and orientation regarding oral hygiene. The prevalence of nickel allergy was determined by the patch test 9 months after the beginning of treatment and occurred in 16 individuals (17.2%). Two groups were then established: the allergic group (AG, n = 16) and the age-paired nonallergic control group (NAG, n = 16). Data were analyzed using the Mann-Whitney U-test and Friedman's analysis of variance (ANOVA) tests (P < or = .05)., Results: Significant differences were present between groups at the T(3) and T(4) evaluations for the LOE index (P = .045 and .009), with allergic individuals showing higher mean values than nonallergic individuals (hyperplasia, change in color, and bleeding). No significant differences were found in the intragroup evaluations between the four evaluations (P > .05)., Conclusions: The results suggest a cumulative effect from nickel throughout orthodontic treatment associated with clinically significant periodontal abnormalities in allergic individuals over time.

Background: The introduction of digital planning programs has made it possible to place dental implants in preplanned positions and being immediately functionally loaded by using prefabricated prostheses., Purpose: The aim of this multicenter study was to describe the 1-year results of digitally planned, immediately loaded edentulous maxillae., Materials and Methods: A total of 312 implants (Brånemark System, TiUnite RP, Nobel Biocare, Göteborg, Sweden) in 52 patients from eight Scandinavian clinics were digitally planned, surgically as well as prosthetically, by using the NobelGuide (Nobel Biocare AB, Göteborg, Sweden) and received prefabricated, immediately loaded fixed prosthetic constructions in the maxillae. Individual implant stability was manually tested at 1-year follow-up., Results: All patients received a Procera Implant Bridge (Nobel Biocare AB); however, in two cases, the bridges were reconstructed due to misfit. In five patients, difficulties in getting the surgical guide completely in position, and in five patients, getting the prostheses completely seated, were noted. All but four patients fulfilled the 1-year follow-up. Two implants were lost during the study period, resulting in a cumulative survival rate of 99.4%. The mean marginal bone resorption from implant placement to the 1-year follow-up was 1.3 mm (SD 1.28). More than 2 mm of marginal resorption was noted in 19% of the implants at this instant. The most frequently reported complications during the first year were gingival hyperplasia and prosthesis-related problems (prosthesis screw loosening, occlusal fractures, and occlusal adjustments)., Conclusion: The 1-year results in this multicenter are promising regarding implant and bridge stability; however, the study is planned to be running for at least 3 years.

Traditional gingivectomy procedures have been a challenge for pediatric dentists who confront issues of patient cooperation and discomfort. Treatment of pediatric patients must involve minimal operative and postoperative discomfort. Laser soft-tissue surgery has been shown to be well accepted by children. For the pediatric patient, the greatest advantage of the laser is the lack of local anesthesia injection and the associated pre- and postoperative discomfort. The following case report describes a gingivectomy procedure performed on a 14-year-old female.

This article describes the periodontal management of a patient with severe aplastic anemia. A 51-year-old female patient was hospitalized with aplastic anemia and was referred for the management of her cyclosporine-induced gingival enlargement and bleeding from her gums. She also complained of pain in the palatal area and the mandibular anterior region. The patient was managed successfully with supra- and subgingival instrumentation, local drug delivery (LDD), electrosurgery, repeated oral hygiene instruction, and constant supervision. The treatment resulted in dramatic improvement in the patient's oral health and quality of life. This report highlights the importance of nonsurgical therapy followed by electrosurgery for the management of residual gingival enlargement.

Management of orthodontic treatment requires specific attention when patients develop medical problems that affect their general health or require treatments that might not be compatible with orthodontic care. This article describes the interface of orthodontic and medical care in a patient who was diagnosed with acute myeloid leukemia midway through her orthodontic treatment.
