Phenytoin Induced Gingival Enlargement

Certain anticonvulsants, cyclosporine, and calcium channel blockers like amlodipine have been shown to produce clinically and histologically similar gingival enlargements in certain susceptible patients in response to local factors. These drugs appear to be similar with respect to their pharmacologic mechanism of action at the cellular level. Therefore, it is tempting to speculate that these agents may act similarly on gingival connective tissue and cause a hyperplastic response. This tissue reaction may involve a disturbance of calcium ion influx into specific cell populations with a resulting alteration in collagen metabolism and other host cell response mechanisms. A connection between ion exchange, folate uptake, collagenase activation, and bacterial inflammation may exist. The management involves Phase I therapy followed by surgical intervention. The purpose of these case reports is to highlight certain modifications in existing surgical techniques like gingivectomy, to have better aesthetic and functional outcome.

Juvenile hyaline fibromatosis: a case report and literatures review / 口腔疾病防治

Objective@#To investigate the clinicopathological characteristics, imaging manifestations, genetic manifestations, diagnosis and treatment of juvenile hyaline fibromatosis.@*Methods @# A case of juvenile hyaline fibromatosis was reported, and the patient's clinical manifestations, imaging examinations, histopathological examinations, genetic changes and treatment were summarized and analyzed.@*Results @#Juvenile hyaloid fibromatosis is more common in infants and children. This patient had typical clinical and pathological manifestations, including posterior occipital masses, skin and subcutaneous nodules, gum hyperplasia, joint contractures, and joint osteolytic lesions. The histopathological lesions were characterized by the proliferation of spindle cells in the tissue accompanied by a large amount of amorphous transparent matrix. Genetic testing was performed to confirm an ANTXR2 gene mutation, consistent with the known genetic changes of juvenile hyaline fibromatosis. The 6-month follow-up of the patient showed that there was no obvious recurrence after resection of the gum and facial mass. In addition to surgery, the treatment of this disease requires multidisciplinary symptomatic treatment combined with rehabilitation and supportive treatment to achieve a better prognostic effect.@*Conclusion@# Juvenile hyaline fibromatosis is a rare nonneoplastic autosomal recessive genetic disease. Mutations in the ANTXR2 gene lead to disorders of collagen synthesis and metabolism in the tissues and further cause subcutaneous nodules, gingival hyperplasia, joint contractures and bone dissolution.

Diferencias fenotípicas de fibroblastos gingivales en sujetos con hiperplasia gingival idiopática frente a sujetos periodontalmente sanos: estudio piloto / Phenotypic differences of gingival fibroblasts in subjects with idiopathic gingival hyperplasia versus periodontally healthy subjects: a pilot study

Objetivo: identificar, describir y diferenciar las características fenotípicas de los fibroblastos gingivales (FGs) en pacientes con hiperplasia gingival idiopática (HGI) e individuos periodontalmente sanos. Métodos: los FGs fueron aislados a partir de tejido gingival de individuos periodontalmente sanos (n=2) y pacientes con HGI (n=2). Los FGs se cultivaron en el medio DMEM (Dulbecco's Modified of Eagle Medium) a 37°C con 5% de CO2. La identificación y localización de la actina, vimentina y mitocondrias en FGs fue realizada y evaluada microscópicamente mediante inmunofluorescencia con anticuerpos monoclonales. La capacidad de migración de los FGs en los pacientes con HGI e individuos sanos también fue estudiada. Resultados: todos los FGs fueron mononucleares, fusiformes y con prolongaciones citoplasmáticas visibles. La faloidina permitió identificar una densa red de actina en los FGs de pacientes con HGI, contrariamente a los FGs de individuos periodontalmente sanos. La vimentina y mitocondrias fueron identificadas en los FGs de individuos sanos y pacientes con HGI sin ninguna alteración en su expresión y localización. La migración de la monocapa de los FGs indicó una actividad de migración celular importante en los FGs de los pacientes con HGI, en relación a los FGs de los individuos periodontalmente sanos. Conclusión: los FGs de pacientes con HGI conservan características fenotípicas celulares similares a los FGs de individuos periodontalmente sanos. Sin embargo, los FGs de pacientes con HGI simulan tener una mayor capacidad migratoria que amerita ser explorada en futuros trabajos de investigación.

Objective: To identify and to describe the phenotypic characteristics of gingival fibroblasts from patients with idiopathic gingival hyperplasia (IGH) and periodontally healthy individuals. Methods: Gingival fibroblasts (GFs) were isolated from gingival tissue from periodontally healthy individuals (n=2) and patients with IGH (n=2). The GFs were grown in DMEM (Dulbecco's Modified of Eagle Medium) at 37°C with 5% CO2. The identification and location of actin, vimentin and mitochondria in GFs were performed and evaluated microscopically by immunofluorescence with monoclonal antibodies. The migration capacity of GFs from IGH and healthy individuals was also studied. Results: All the GFs were mononuclear, fusiform and with visible cytoplasmic extensions. The phalloidin allowed to identify a dense actin network in the GFs of patients with IGH, contrary to the GFs of periodontally healthy individuals. Vimentin and mitochondria were identified in the GFs of healthy individuals and patients with IGH without any alteration in their expression and location. Monolayer migration of GFs indicates significant cell migration activity in the GFs of patients with IGH in relation to the GFs of periodontally healthy individuals. Conclusion: GFs from patients with IGH retain cellular phenotypic characteristic similar to GFs from periodontally healthy individuals. However, the GFs of patients with IGH simulate having a greater migratory capacity that deserves to be explored in future research works.

Prevalence of Gingival Hyperplasia Induced by Anticonvulsants: A Systematic Review / Prevalência da Hiperplasia Gengival Induzida pelo uso de anticonvulsivantes: Revisão sistemática

Objective: Gingival hyperplasia (GH) is one of the side effects of anticonvulsant drugs. The aim of this study was to verify the prevalence of GH associated with the use of anticonvulsant, through a systematic review. Material and Methods: Systematic search was done at databases Pubmed and Embase between January 1984 and March of 2020 for identification of articles addressing the prevalence of GH associated with the use of anticonvulsant drugs. The methodological index for non-randomized studies (MINORS) was independently assessed for quality in the selected papers. Results: The search identified 4.471 references. Nine articles were selected and evaluated 632 participants. All of the studies included in the systematic review showed a low risk of bias. The anticonvulsants used by patients were carbamazepine, ethosuximide, phenytoin, primidone, phenobarbital, sodium valproate. The studies showed a correlation between different types of anticonvulsants and GH prevalence, with a range from 0% to 73%. Among the anticonvulsants used, phenytoin showed the greatest incidence of GH, varying between 15.61% and 73% in patients. Conclusion: In the analysis of the results obtained in the literature, it is possible to notice that the great majority of studies presented incidence of GH associated with anticonvulsant use. However, further studies are necessary to understand the anticonvulsant action mechanism inducing GH, as well as the prevention forms, given that GH is a significant side effect. (AU)

Objetivo: Hiperplasia gengival (HG) é um dos efeitos colaterais das drogas anticonvulsivantes. O objetivo deste estudo foi verificar a prevalência de HG associada ao uso de anticonvulsivantes, por meio de uma revisão sistemática. Material e Métodos: A busca sistemática foi realizada nas bases de dados Pubmed e Embase entre janeiro de 1984 e março de 2020 para identificação de artigos que abordassem a prevalência de HG associada ao uso de drogas anticonvulsivantes. Foi avaliado independentemente, o risco de viés através do "Methodological index for non-randomized studies" (MINORS), para análise da qualidade dos trabalhos selecionados. Resultados: A pesquisa identificou 4.471 referências. Nove artigos foram selecionados e avaliaram 632 participantes. Todos os estudos incluídos na revisão sistemática mostraram baixo risco de viés. Os anticonvulsivantes utilizados pelos pacientes foram carbamazepina, etossuximida, fenitoína, primidona, fenobarbital e valproato de sódio. Os estudos mostraram correlação entre os diferentes tipos de anticonvulsivantes e a prevalência de HG, com variação entre 0% a 73%. Entre os anticonvulsivantes utilizados, a fenitoína apresentou a maior incidência de HG, variando entre 15,61% e 73% em pacientes. Conclusão: Na análise dos resultados obtidos na literatura, é possível notar que a grande maioria dos estudos apresentou incidência de HG associada ao uso de anticonvulsivantes. No entanto, estudos adicionais são necessários para compreender o mecanismo de ação do anticonvulsivante para a indução da HG, bem como as formas de prevenção, dado que a HG é um efeito colateral significativo (AU)

Hiperplasia gengival durante uso de ciclosporina / Gingival hyperplasia during cyclosporine use

Paciente do sexo masculino, com 24 anos, portador de dermatite atópica desde o primeiro ano de vida. Começou a evoluir com forma grave da dermatite atópica aos 17 anos, e devido à refratariedade clínica ao tratamento convencional tópico, foi encaminhado para serviço de referência. Após otimizar os cuidados com uso de emolientes, corticoides tópicos e cursos de antibioticoterapia, manteve persistência de eczema generalizado, com SCORAD oscilando entre 40 e 50 no período de 4 meses. Dessa forma, optou-se por terapia sistêmica, sendo iniciado o uso de ciclosporina oral na dose de 200 mg. A resposta terapêutica com a ciclosporina foi percebida após 4 semanas, sendo refletida na redução do escore de gravidade (SCORAD=10). Durante o seguimento, além da melhora clínica, eram monitorados potenciais eventos adversos. O paciente fez uso da ciclosporina durante 5 anos sem apresentar eventos adversos, com necessidade de aumento de dose para 300 mg/dia dois anos após início da medicação. Porém, neste quinto ano de uso da ciclosporina, o paciente apresentou hipertrofia gengival importante. Assim, optou-se por reduzir a dose de ciclosporina de 300 para 200 mg/dia. Nenhum outro sinal ou sintoma foi observado, e os exames laboratoriais também não mostraram qualquer toxicidade. O paciente se mostrou resistente à redução da medicação, pois o temor de piora das lesões de pele o aflige muito. Orientamos sobre a necessidade de melhorar a higiene bucal de forma disciplinada, e agendamos reavaliação clínica mensal. Além disso, foi encaminhado para avaliação odontológica.

A 24-year-old man had atopic dermatitis since the first year of life. He first developed a severe form of atopic dermatitis at the age of 17, and because of clinical refractoriness to conventional topical treatment, he was referred to an excellence center. After care was optimized with emollients, topical corticosteroids and courses of antibiotic therapy, generalized eczema persisted, with Scoring Atopic Dermatitis (SCORAD) score oscillating between 40 and 50 in a period of 4 months. Thus, systemic therapy was chosen, with use of oral cyclosporine at a dose of 200 mg. Therapeutic response with cyclosporine was observed after 4 weeks, with a reduction in the severity score (SCORAD = 10). During followup, in addition to clinical improvement, potential adverse events were monitored. The patient used cyclosporine for 5 years with no adverse events, requiring a dose increase to 300 mg 2 years after initiating the medication. However, in the 5th year of cyclosporine use, the patient had significant gingival hyperplasia. Thus, we decided to reduce the dose of cyclosporine from 300 to 200 mg. No other signs or symptoms were observed and laboratory tests also showed no toxicity. The patient was resistant to reducing the medication, as he feared the skin lesions would aggravate. We advised him on the need to improve oral hygiene in a disciplined manner and scheduled a monthly clinical reevaluation. In addition, he was referred to dental evaluation.

Idiopathic gingival fibromatosis: a case report and literature review / 口腔疾病防治

Objective @#To explore the etiology, clinical manifestations, diagnosis, differential diagnosis and treatment of idiopathic gingival fibromatosis, and to provide references for clinical diagnosis and treatment.@*Methods @#The clinical data and related literatures of a case of idiopathicgingival fibroma that occurred in the oral cavity were retrospectively analyzed. @*Results @#Total periodontal treatment was performed for the patient, and the gingival morphology was improved after periodontal surgery in the anterior region. Idiopathic gingival fibromatosis is a rare disease characterized by gingival tissue hyperplasia. The etiology and pathogenesis are unknown. The disease can occur in young children. Generally, it occurs after the permanent teeth erupt, and it manifests as extensive gingival hyperplasia, which can affect the entire gingival margin, gingival papilla and attached gingival, and can even reach the membrane-gingival junction. The pathological changes include thickening of the spinous layer of the gingival epithelium, significant increases in the epithelial styloid process, increases in the connective tissue volume, and filling with large collagen fiber bundles and a large number of fibroblasts. The blood vessels are relatively small, and inflammation is not obvious. Clinically, this disease needs to be distinguished from drug-induced gingival hyperplasia and chronic gingivitis with hyperplasia as the main manifestation. At present, the treatment of idiopathic gingival fibromatosis is mainly gingival angioplasty. The disease easily relapses after surgery. The recurrence rate is related to the quality of oral hygiene. After recurrence, it can be treated again.@*Conclusion@# Idiopathic gingival fibromatosis is relatively rare, and the diagnosis mainly depends on the history of inquiry, clinical manifestations and pathological examination. The treatment is mainly surgical resection, and future research should focus on finding a more effective treatment.

Hereditary gingival fibromatosis: a three-generation case report / 华西口腔医学杂志

Hiperplasia gengival associada ao uso de anticonvulsivantes à base de ácido valpróico / Gingival hyperplasia associated with the use of valproic acid-based anticonvulsants

Anticonvulsivantes são drogas capazes de modificar a resposta dos tecidos gengivais a processos inflamatórios na presença ou não de placa bacteriana, induzindo o crescimento gengival. O presente trabalho revisou a respeito das alterações periodontais exacerbadas pela utilização de anticonvulsivantes à base de ácido valpróico. Foram incluídos no estudo todos os trabalhos que pudessem descrever algo a respeito das características bioquímicas e farmacológicas do ácido valpróico e sua correlação com as alterações periodontais hiperplásicas. A pesquisa bibliográfica foi realizada nas bases Scopus, PubMed, BVS, Web of Science e Scielo utilizando os descritores "sodium valproate" "valproic acid" "gingival enlargement" e "gingival hyperplasia". Como resultado, um total de 111 referências foram encontradas e 54 artigos contemplavam todos os critérios de inclusão e foram submetidos a análise qualitativa. Algumas hipóteses sugerem um papel determinante dos fibroblastos, citocinas inflamatórias e também com a síntese de metaloproteinases na resposta tecidual. Concluiu-se que o mecanismo interveniente na histopatogênese do tecido conjuntivo desencadeadas pelo ácido valpróico e com repercussões nos tecidos periodontais ainda é pouco compreendido e apresentam pouca relação com o acúmulo de biofilme dentário, sendo decorrentes mais por mecanismos atribuídos ao próprio medicamento (AU)

Anticonvulsants are drugs capable of modifying the response of gingival tissues to inflammatory processes in the presence or absence of plaque, inducing gingival growth. The present study reviewed the periodontal changes exacerbated by the use of valproic acid-based anticonvulsants. All studies that could describe something about the biochemical and pharmacological characteristics of valproic acid and its correlation with hyperplasic periodontal changes were included in the study. The literature search was carried out in the bases of Scopus, PubMed, BVS, Web of Science and Scielo using the descriptors "sodium valproate" "valproic acid" "gingival enlargement" and "gingival hyperplasia". As a result, a total of 111 references were found and 54 articles covered all the inclusion criteria and were included in the qualitative analysis. Some hypotheses suggest a role of fibroblasts, inflammatory cytokines and also the synthesis of metalloproteinases in the tissue response. It was concluded that the mechanism involved in the histopathogenesis of connective tissue triggered by valproic acid and with repercussions on the periodontal tissues is still poorly understood and presents little relation with the accumulation of dental biofilm, being more due to mechanisms attributed to the drug itself (AU)

Surgical and nonsurgical treatment of papillary hyperplasia: A case report / Tratamiento quirúrgico y no quirúrgico de la hiperplasia papilar inflamatoria: Reporte de Caso

Profile evaluation of patients diagnosed with non-neoplastic proliferative lesions in a dentistry clinic

Non-neoplastic proliferative lesions (NNPLs) are alterations that affect oral mucosal tissues. The etiology of these lesions is associated with local irritant processes, principally inflammation, infections and mechanical irritants. NNPLs are classified into four groups: inflammatory fibrous hyperplasia, pyogenic granuloma, peripheral ossifying fibroma, and peripheral giant cell lesion. Aim: This cross-sectional, quantitative, retrospective, analytical, informative and educational study aimed to evaluate the profiles of patients who were diagnosed with any non-neoplastic proliferative lesion in the Unimontes Stomatology Clinic, Brazil. Methods: From January 2001 to June 2012, 1505 patients were counted who underwent anatomopathological examination, in addition to evaluations for other conditions. Results: Of these 1505 patients, 223 were diagnosed with some type of non-neoplastic proliferative lesion, and statistical analysis showed that 76% were female and 24% male and that 23.3% were between 41 and 50 years of age. Inflammatory fibrous hyperplasia was the most common NNPL (86.5%). Conclusion: Due to the high frequency of these lesions in the dental clinic, this type of survey has significant relevance for informing health professionals about these proliferative processes. This information is necessary, since the dentist is intimately involved in both the etiology, treatment and prevention of these lesions

La Amelogénesis Imperfecta (AI) es alteración de la estructura y apariencia del esmalte dental de origen genético, puede presentarse como defecto aislado o sistémico. El Síndrome Amelogénesis imperfecta­Nefrocalcinosis (OMIM # 204690), también conocido como Síndrome Esmalte-Renal (ERS, en inglés), se caracteriza por la presencia de AI de tipo hipoplásico, hiperplasia gingival con mineralizaciones ectópicas, retraso y/o ausencia de la erupción dental y Nefrocalcinosis. Este síndrome es asociado a mutaciones autosómicas recesivas del gen FAM20A. El objetivo de esta revisión es exponer las características clínicas y fenotípicas de pacientes con el Síndrome Amelogénesis imperfecta­ Nefrocalcinosis. La obtención del material fue realizado mediante una búsqueda electrónica en las bases de datos MEDLINE (PubMed), EBSCO- Host y Scopus (ScienceDirect). Los resultados confirman la escasa frecuencia de casos clínicos con el Síndrome Amelogénesis imperfecta­Nefrocalcinosis. Las características clínicas y fenotípicas se exponen de manera clara, sencilla y precisa. Se recomienda a los odontólogos generales y odontólogos pediátricos que al diagnosticar una AI, particularmente de tipo hipoplásico, realicen una detallada historia médica personal - familiar y contemplen una interconsulta con el servicio de nefrología que permita diagnosticar o realizar un seguimiento al estado renal del paciente de una forma preventiva.

Amelogenesis Imperfecta (AI) is an alteration of the structure and appearance of dental enamel of genetic origin that can occur as an isolated or systemic defect. The Amelogenesis Imperfecta-Nefrocalcinosis Syndrome (OMIM # 204690), also known as Enamel-Renal Syndrome (ERS), is characterized by the presence of hypoplastic AI, gingival hyperplasia with ectopic mineralization, delayed tooth eruption and Nephrocalcinosis. This syndrome is associated with autosomal recessive mutations of the FAM20A gene. The aim of this review is to present the clinical and phenotypic characteristics of patients with the Amelogenesis Imperfecta-Nefrocalcinosis Syndrome. The material was obtained through an online search of MEDLINE database (PubMed), EBSCO-Host and Scopus (ScienceDirect). The results confirm the low frequency of clinical cases reported with Syndrome Amelogenesis Imperfecta-Nefrocalcinosis. The clinical and phenotypic characteristics were exposed in a clear, simple and precise way. It is recommended to general dentists and pediatric dentists that, when diagnosing an AI, particularly of hypoplastic type, they perform a detailed personal-family medical history and contemplate an interconsultation with the nephrology service that allows to diagnose or monitor the patient's renal status in a preventive style.

Corrección quirúrgica en una adolescente con hiperplasia gingival hereditaria / Surgical correction in an adolescent with hereditary gingival hyperplasia

Se describe el caso clínico de una adolescente que fue atendida en la consulta de Periodoncia del Hospital General Docente Dr Juan Bruno Zayas Alfonso de Santiago de Cuba, por presentar agrandamiento de las encías desde hacía más de un año, lo que le dificultaba la masticación de los alimentos y, por tanto, le producía trastornos digestivos transitorios, además de afectar su estética. Luego de realizados los exámenes físico y complementarios, se estableció el diagnóstico presuntivo de hiperplasia gingival hereditaria o familiar y se indicó el tratamiento, que incluyó 3 fases: la inicial, la correctiva quirúrgica y la de soporte periodontal. En la fase quirúrgica se tomó una muestra hística cuyo análisis anatomopatológico confirmó el diagnóstico presuntivo inicial

The case report of an adolescent that was assisted in the Periodontics Service of Dr Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba is described. He presented enlargement of the gums for more than a year, which made mastication of foods difficult and therefore, transitory digestive dysfunctions took place, besides affecting her aesthetics. After the physical and complementary tests, the presumptive diagnosis of hereditary or family gingival hyperplasia was established and the treatment was indicated into 3 phases: initial phase, surgical corrective phase and that of periodontal support. In the surgical phase a tissue sample was taken which pathologic analysis confirmed the initial presumptive diagnosis

Manifestaciones periodontales de la leucemia mieloide aguda: reporte de un caso / Periodontal manifestations of acute myeloid leukemia: a case report

Fundamento: la leucemia se considera una neoplasia maligna que se desarrolla en la médula ósea. En esta enfermedad la respuesta inflamatoria en presencia de irritantes locales es mucho mayor, la capacidad defensiva está disminuida y las manifestaciones bucales son de las primeras en aparecer. El diagnóstico específico de la leucemia demanda un buen interrogatorio, examen físico completo y estudios hematológicos minuciosos. Objetivo: presentar un caso de leucemia mieloide aguda que desarrolló manifestaciones periodontales y describir el tratamiento periodontal de las leucemias. Caso clínico: se presenta el caso de un paciente con pérdida de la morfología gingival generalizada, encías hipercoloreadas, con aumento de volumen no doloroso, de consistencia esponjosa, que en algunos sitios cubría la corona completa de los dientes, lesiones ulceradas, halitosis y adenopatías submandibulares. A través del interrogatorio y el ánalisis del cuadro clínico periodontal se decidió la remisión al servicio de Hematología Clínica, donde se le practicaron los exámenes de laboratorio, se confirmó la presencia de una leucemia mieloide aguda y el paciente fue atendido hasta su fallecimiento. Conclusiones: los estomatólogos deben conocer las manifestaciones periodontales de la leucemia para realizar la remisión oportuna del paciente a un servicio de Hematología Clínica o Medicina Interna, y efectuar la eliminación de los factores locales, el minucioso control de la placa dental, la limpieza profesional regular y enjuagues con clorhexidina con vistas a aliviar las lesiones en la boca. El médico del paciente siempre debe ser consultado antes de llevar a cabo cualquier tratamiento.

Background: leukemia is considered a malignant neoplasm that is developed in the marrow bone. In this entity the inflammatory response in the presence of local irritants is higher and the defensive capacity is diminished. The specific diagnosis of leukemia demands a good interrogation, complete physical exam and detailed hematological studies. Objective: to present a case of acute myeloid leukemia which developed periodontal manifestations and to describe the treatment of leukemias. Clinical case: it is presented the case of a patient with loss of the generalized gingival morphology of spongy consistency, hipercolored, with a no painful increase in volume and that in some places covered the full crown of the teeth, ulcerated lesions, halitosis and submandibular lymphadenopathy. It was decided through the questioning and the periodontal clinical manifestations analysis, the remission of the patient to the Clinical Hematology Service, where laboratory tests were carried out, in addition it was confirmed the presence of acute myeloid leukemia and the patient was attended until he died. Conclusions: the dentists should know the periodontal manifestations of leukemia to carry out the convenient remission of the patient to a Service of Clinical Hematology, and to eliminate the local factors, the meticulous control of dental plaque, the regular professional cleaning and rinses with chlorhexidine with the purpose to alleviate the lesions in the mouth. The patient's physician should always be consulted before carrying out any treatment.

Expression of Wnt1 and β-catenin in the gingival tissure with gingival overgrowth induced by nifedipine / 实用口腔医学杂志

Objective:To study the expression of Wnt/β-catenin signaling pathway related proteins Wnt1 and β-catenin protein in gingival tissues of the patients with drug-induced gingival overgrowth(DGO) caused by nifedipine.Methods:Wnt1 and β-catenin expression were tested with Western Blot and RT-PCR in gingival tissues of 10 cases of DGO induced by nifedipine,10 cases of high blood pressure with gingival hyperplasia(without use of any medicine) and 10 cases of healthy control.Results:In the gingival tissues of DGO group the levels of Wnt1 and β-catenin protein and mRNA were significantly higher than those of the healthy control group(P ＜ 0.05) and the high blood pressure group (P ＜ 0.05).Conclusion:The levels of Wnt1 and β-catenin are increased in nifedipine induced gingival hyperplasia.The gingival hyperplasia may be caused by the promotion of gingival fibroblast proliferation through Wnt/β-catenin signaling pathway.

Agrandamiento gingival por ciclosporina: reporte de un caso / Gingival enlargement due to cyclosporine: a case report

El agrandamiento gingival (AG) es el aumento de volumen anormal de la encía que genera cambios estéticos y síntomas clínicos como sangrado gingival espontáneo o inducido, trastornos periodontales y migración patológica dentaria, entre otros. Este proceso patológico puede ser un efecto secundario a ciertos fármacos como anticonvulsivantes, bloqueadores de canales de calcio e inmunosupresores. Se presenta el caso de un paciente sexo masculino de 74 años de edad con antecedentes de trasplante renal, en tratamiento con ciclosporina, que acude por aumento del volumen intraoral, clínicamente compatible con agrandamiento gingival. Se realiza tratamiento basado en exodoncias, biopsia y control de placa. A los 2 meses se pudo observar una regresión de la lesión, y se confirma el diagnóstico con el estudio histopatológico. El manejo actual del tratamiento de esta enfermedad se basa en el control de la placa. Se sugiere dar un enfoque multidisciplinario y crear protocolos para derivar oportunamente antes de la expresión más agresiva de la enfermedad.

Gingival enlargement is an abnormal increased volume of the gum that induces cosmetic changes and clinical symptoms, such as gingival bleeding, periodontal disorders, pathological tooth migration, among others. This condition can be a side effect of certain drugs such as anticonvulsants, calcium channel blockers, and immunosuppressants. A 74 year-old male patient with a medical record of kidney transplant secondary to chronic renal failure receiving cyclosporine for the past 14 years is referred to our Hospital with the chief complaint of gingival enlargement. The treatment is based on tooth extractions, biopsy and periodontal treatment. A complete regression of the lesion was observed after two months. The current approach to treat this disease is focused on plaque control. A multidisciplinary approach should be used and clinical protocols prepared that allow early treatment and avoidance of more aggressive disease expression.

The Gingival Fibromatosis (GF) is described as a rare oral condition, clinically manifested by a slow, progressive, diffuse, and benign growth of gingival tissues. This condition can manifest itself in isolation, in combination with other systemic diseases or as a component of syndromes. GF may have an identifiable etiology or be idiopathic. Depending on the severity of each case, GF may result in significant functional and aesthetic disorders, mainly related to the difficulty of cleaning, speech and swallowing due to formation of large gingival tissue masses. This paper proposes a review of the clinical features, diagnosis and treatment of gingival fibromatosis and reports a severe case of this condition that was surgically treated... (AU)

Amlodipine induced gingival hyperplasia: a case report.

A 55-year-old South Indian male with hypertension, benign prostate hypertrophy and old myocardial infarction was admitted with painless inflammation of gingiva. He received amlodipine 5 mg once a day, atorvastatin 10 mg once a day, aspirin 75 mg once a day and rabeprazole 20 mg once a day for past 5 months. The patient in the case presented had gingival hyperplasia as a result of managing his hypertension with amlodipine. Calcium channel blockers are one of the most widely used antihypertensive and are known for causing gingival hyperplasia as an adverse effect. It may develop as a result of two inflammatory and non-inflammatory pathways. The problem completely resolved when the offending drug was withdrawn and he was switched over to an angiotensin receptor blocker. The present case is interesting as it occurred with a low dose of amlodipine (5 mg) and appeared on administration for 5 months. This paper aims at drawing the attention of clinicians toward adverse effects of amlodipine along with a brief review on the management of hyperplasia without surgical interventions.

Phenytoin-Induced Gingival Overgrowth Management with Periodontal Treatment

Phenytoin-induced gingival overgrowth (PIGO) is a common complication of the continuous use of medications. This paper presents a case of PIGO hindering oral function and compromising oral hygiene and aesthetics, which was treated with a combination of nonsurgical and surgical periodontal therapies. A 39-year-old male patient was referred for dental treatment with several complaints, especially upper and lower gingival overgrowth that hindered speech and swallowing. Generalized deep probing pockets and bone loss were detected. Diagnosis of gingival overgrowth associated with phenytoin and chronic periodontitis was established. The treatment plan consisted of conservative therapy with education on oral health, motivation and meticulous oral hygiene instruction in combination with scaling and root planing. During the revaluation period, a marked reduction in the clinical parameters was noted, particularly probing pocket depth reduction. Surgical therapy for removal of gingival overgrowth was also performed to achieve pocket reduction. Supportive periodontal therapy was proposed and the patient is currently under follow-up for 4 years. Management of PIGO may be obtained by the use of periodontal procedures combined with good oral hygiene and periodontal supportive care.

O crescimento gengival induzido pela fenitoína é uma complicação comum do uso contínuo da medicacão. Este artigo apresenta um caso de crescimento gengival excessivo que dificultava a função oral e comprometia a higiene oral e a estética, o qual foi tratado com uma combinação de terapias periodontais não-cirúrgicas e cirúrgicas. Paciente masculino de 39 anos de idade foi encaminhado para tratamento odontológico com várias queixas, especialmente do crescimento gengival superior e inferior que prejudicava a fala e deglutição. Profundidades de sondagens severas generalizadas e perda óssea foram detectadas. Diagnóstico de crescimento gengival induzido pela fenitoína e periodontite crônica foi estabelecido. O plano de tratamento consistiu de terapia conservadora com educação, motivação e meticulosa instrução de higiene oral em associação com raspagem e alisamento corono-radicular. Durante o período de reavaliação, uma acentuada redução nos parâmentros clínicos foi observada, principalmente uma redução das profundidades de sondagem. Terapia cirúrgica para remoção do excesso de tecido gengival também foi realizada para conseguir redução das bolsas. Terapia periodontal de suporte foi proposta e o paciente está atualmente sob acompanhamento por um período de 4 anos. O manejo do crescimento gengival induzido pela fenitoína pode ser obtido pelo uso de procedimentos periodontais combinados com uma boa higiene oral e cuidados periodontais de suporte.
