RESUMO

Objetivo: La gingivitis espongiótica es una patología benigna poco común y una entidad clínica patológica poco frecuente que los odontólogos pueden observar durante la atención odontológica. Es importante conocer la misma para poder diagnosticarla adecuadamente, describir sus características clínicas y elaborar un plan para su tratamiento. El objetivo de este artículo es presentar un caso clínico de esta patología poco conocida, describir sus características y su manejo clínico. Caso clínico: Un niño de 7 años que ingresó derivado por su odontólogo a la cátedra de Estomatología de la Facultad de Odontología de la Universidad Nacional de Córdoba, Argentina, presentaba en la encía libre e insertada del maxilar superior una lesión con ausencia de sintomatología y evolución crónica, benigna y con cambios estéticos notorios. Se deriva a la cátedra de Periodoncia para realizar un tratamiento interdisciplinario. Tuvo una respuesta favorable al tratamiento de la lesión, y se realizó un seguimiento periódico de la misma evitando la técnica quirúrgica convencional para su tratamiento.(AU)

Aim: Spongiotic gingivitis is a rare benign pathology and a rare clinical pathological entity that dentists can observe during dental care. It is important to know it to be able to properly diagnose it, describe its clinical characteristics and develop a plan for its treatment. The aim of this article is to present a clinical case of this little-known pathology and describe its characteristics as well as its clinical management. Clinical case: A 7-yeard-old child who was referred by his dentist to the Department of Stomatology of the Faculty of Dentistry of the National University of Córdoba, Argentina, presented a lesion in the free and inserted gingiva of the upper jaw, with absence of symptoms and chronic, benign evolution with notable aesthetic changes. He is referred to the Periodontics department to perform interdisciplinary treatment. He had a favorable response to the treatment of the lesion, and a periodic follow-up was carried out, avoiding the conventional surgical technique for its treatment.(AU)

RESUMO

The aim of this study is to report a case of an extensive and aggressive gingival lesion, compatible with localized juvenile spongiotic gingival hyperplasia (LJSGH), demonstrating the difficulties of diagnosis and management. A 33 years-old male patient was referred to Department of Oral and Maxillofacial Surgery at the Erasto Gaertner Hospital with a lesion on anterior maxillary gingiva, with 3-months evolution period. The patient had complete permanent dentition and good oral hygiene. The gingival hyperplasia involved the gums of teeth 11 and 12, and was solitary, asymptomatic, red, flaccid and bleeding on palpation. No palpable lymph nodes were found. An incisional biopsy was performed, with anatomopathological result of "squamous mucosa with pseudoepitheliomatous hyperplasia and lymphoplasmocytic infiltrate with neutrophils". The lesion was fully excised and the anatomopathological report confirmed the biopsy showing no malignancy in the sample and negative for the investigation of fungus. Biofilm control, mouth rinses with hydrogen peroxide, Chlorhexidine Digluconate 0.12% and Amoxicilin 500mg+Potassium Clavulanate 125mg have not demonstrated efficacy, and the patient kept showing recurrence of the lesion in short time even after the complete excision. Against this situation, the patient was referred to an infectologist, by the suspicion of a resistant microorganism. He started antibacterial therapy with Sulfamethoxazole 800mg+Trimethoprim 160mg that showed good results after 3 months. Currently, the patient remains in follow-up without signs of recurrence. LJSGH is a clinicopathological benign entity that appears in young patients as a soft, bleeding and reddish mass, mainly in the buccal gingiva of the upper anterior maxilla and lonely in most cases. The management of this condition is very difficult because of the few cases described in literature, and establishing the correct diagnosis is essential to ensure that the appropriate treatment is followed.

RESUMO

The localized juvenile spongiotic gingival hyperplasia (LJSGH) mainly affects the maxillary vestibular attached gingiva of juvenile patients, without sex predilection. Similar lesions involving extragingival sites have not been reported to date. Here, we report 2 cases of extragingival soft tissue lesions with similar clinicopathological features to those reported in LJSGH and 12 cases of intraoral reactive soft tissue lesions microscopically showing LJSGH-like focal areas. The 2 cases were adult patients, affecting the maxillary alveolar ridge (55-year-old female) and hard palate (78-year-old male), which were diagnosed as "spongiotic hyperplasia of the oral mucosa." The 12 intraoral reactive soft tissue lesions (6 men and 6 women; mean age, 49.5 years) were diagnosed as inflammatory fibrous hyperplasia (n = 6), peripheral ossifying fibroma (n = 3), and pyogenic granuloma (n = 3), each of them presenting LJSGH-like focal areas. By immunohistochemistry, the spongiotic hyperplasia areas showed positivity for CK19, CK14, CK34ßE12, and CAM5.2 (weak/focal), while CK4 was negative. Considering the anatomical locations (extragingival) of these 2 cases, the term "spongiotic hyperplasia of the oral mucosa" is suggested. Moreover, LJSGH-like focal areas can be detected when microscopically assessing common intraoral reactive soft tissue lesions.

RESUMO

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.

RESUMO

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)

RESUMO

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.

RESUMO

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)

RESUMO

Dentures with dental plaque predispose recurrent hyperplasia on the palatal mucosa. Surgical procedures for the treatment of inflammatory papillary hyperplasia involve postsurgical discomfort and morbidity. This repot describes clinical and histologic aspects of a patient with severe akantolitic inflammatory papillary hyperplasia. The palatal mucosa was treated with a surgical bur with a low-speed handpiece. A new removable denture was performed and adapted. A follow-up of 4 years showed staility of health at palatal mucosa. Patient referred low discomfort and morbidity when using bur technique. Control of removable denture was critical for long-term healing and soft tissue stability.

Las prótesis dentales con placa bacteriana predisponen a la hiperplasia recurrente en la mucosa palatina. Los procedimientos quirúrgicos para el tratamiento de la hiperplasia papilar inflamatoria implican molestias y morbilidad posquirúrgicas. Este reporte describe los aspectos clínicos e histológicos de un paciente con hiperplasia papilar inflamatoria acantolítica severa. La mucosa palatina fue tratada con una fresa quirúrgica con una pieza de mano de baja velocidad. Se realizó y adaptó una nueva prótesis parcial removible. Después de un seguimiento de 4 años, se encontró estabilidad de la salud de la mucosa palatina. El paciente se refirió a la baja incomodidad y morbilidad al usar la técnica de la fresa. El control de la prótesis parcial removible fue crítico para la cicatrización a largo plazo y la estabilidad de los tejidos blandos, evitando la recidiva de la hiperplasia papilar inflamatoria.

RESUMO

African pygmy hedgehogs (Atelerix albiventris) frequently develop oral neoplasms, and most of these neoplasms are malignant. We characterized oral masses detected in hedgehogs at clinical examination. During a 1-y period, we diagnosed oral cavity masses in 27 privately owned hedgehogs; 16 were female and 11 were male, with ages of 2-7 y (mean: 4.3 y). Eight masses were non-neoplastic and were diagnosed as gingival hyperplasia (GH). Nineteen masses were neoplastic, of which 17 were squamous cell carcinomas (SCCs) and 2 were mesenchymal tumors (1 spindle cell tumor of probable neural origin, and 1 hemangiosarcoma). The GHs were noninvasive, exophytic, and did not recur after surgical excision. The SCCs were highly invasive tumors that induced facial deformation and were located in the caudal portion of the oral cavity, with 12 of them arising from the right-caudal maxilla. Thus, clinical signs, growth pattern, and anatomic location can be used to suspect a diagnosis of SCC among the other possible diagnoses, such as GH, in this location. However, histopathology is necessary for confirmation. Also, hemangiosarcoma should be considered among the differential diagnoses.

RESUMO

ABSTRACT Peripheral ossifying fibroma (POF) is a benign lesion, nodular, firm on palpation; the base is sessile or pedunculated; similar in color to the mucosa and epithelium; it may be preserved or ulcerated. It is prevalent in female and exclusively affects the gingiva. It is usually associated with irritating factors such as caries, dental plaque, among others. The objective of the present study is to report the case of a 27-years-old female patient, presenting a lesion in the mandible, complaining of an increased volume. Surgical excision was the treatment of choice. The patient is 24 months postoperatively with no signs of relapse.

RESUMEN El fibroma osificante periférico es una lesión benigna, nodular, firme a la palpación, de base sésil o pediculada, de color similar a la mucosa y al epitelio; puede estar intacto o ulcerado. Se observa más en mujeres y acomete solamente la encía. La lesión se asocia a factores irritantes, como caries, cálculo dental, entre otros. El objetivo del presente estudio es reportar el caso de una paciente de 27 años de edad, que ha presentado lesión en la mandíbula, quejando-se de aumento de volumen. La escisión quirúrgica ha sido el tratamiento de elección. La paciente encuentra se con 24 meses de postoperatorio, sin señales de recidva.

RESUMO O fibroma ossificante periférico (FOP) é uma lesão benigna, nodular, firme à palpação, de base séssil ou pediculada, com coloração semelhante à mucosa e ao epitélio; pode estar íntegro ou ulcerado. Prevalece no gênero feminino e acomete exclusivamente a gengiva. Associa-se a fatores irritantes, como cárie, cálculo dentário, entre outros. O objetivo do presente estudo é relatar o caso de uma paciente de 27 anos de idade, que apresentou lesão em mandíbula, queixando-se de aumento de volume. A excisão cirúrgica foi o tratamento de escolha. A paciente encontra-se com 24 meses de pós-operatório, sem sinais de recidiva.

RESUMO

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

RESUMO

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.

RESUMO

INTRODUCTION: Hereditary gingival fibromatosis (HGF) is a rare disease characterized by gingival enlargement, normal color with benign and firm consistency. This growth may be exacerbated by use of drugs and plaque build-up. The treatment for this clinical condition is surgical excision of the enlarged gingival tissue or the extraction of all teeth. CASE REPORT: A 20-year-old Brazilian female handicapped patient with a chief complaint of exaggerated gingival enlargement who had been prescribed Carbamazepine and Gardenal was referred to our center. According to the clinical presentation and family history, the final diagnosis of gingival enlargement was HGF. Full dental treatment was performed, including basic periodontal treatment, restorations, sealants, and gingivoplasty with internal bevel. Special care was taken to ensure that there was no change in patient's anticonvulsant medication. The patient has been monitored for seven years without signs of recurrence of gingival hyperplasia due to constant professional and home control of plaque.

RESUMO

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

RESUMO

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.

RESUMO

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.

RESUMO

A Fibromatose Gengival (FG) é descrita como uma condição bucal rara, clinicamente manifestada por um crescimento lento, progressivo, difuso e benigno dos tecidos gengivais. Essa condição pode se manifestar de forma isolada, em associação a outras doenças sistêmicas ou como componente de síndromes. A FG pode ter uma etiologia identificável ou ser idiopática. Em função da severidade de cada caso, pode acarretar transtornos funcionais e estéticos significativos, sobretudo, relacionado à dificuldade de higienização, fala e deglutição, devido à formação de grandes massas teciduais na gengiva. O presente trabalho propõe a revisão dos aspectos clínicos, diagnósticos e terapêuticos da Fibromatose Gengival e relata um caso severo desta doença que foi tratada cirurgicamente... (AU)

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)

RESUMO

O presente trabalho tem o objetivo de relatar o caso de uma paciente diagnosticada com sorriso gengival, a qual foi tratada com aplicação de toxina botulínica tipo A. Paciente do gênero feminino, 23 anos, procurou atendimento odontológico relatando insatisfação com a quantidade de gengiva exposta durante o sorriso. O diagnóstico foi de sorriso gengival com origem no excesso de crescimento vertical da maxila. O tratamento com cirurgia ortognática, indicado quando há desarmonia do sorriso devido a um problema ósseo, foi prontamente rejeitado pela paciente. Assim, sugeriu-se a aplicação da toxina botulínica tipo A com o objetivo de relaxar os músculos elevadores do lábio superior e da asa do nariz e os elevadores do lábio superior (músculos ELSAN), diminuindo a faixa de gengiva exposta ao sorrir. No terceiro dia após a aplicação, os primeiros sinais clínicos do efeito do medicamento foram percebidos pela paciente, a qual relatou efeito máximo após 14 dias. A mesma relatou extrema satisfação com o tratamento, considerando o procedimento indolor e sem efeitos adversos. Consultas de retorno foram realizadas com 15, 90, 120 e 150 dias. Aos 120 dias, o efeito do tratamento ainda estava presente. No último retorno, constatou-se o fim da ação do medicamento e retorno à situação inicial. Desta maneira, a toxina botulínica tipo A mostrou-se como uma alternativa de tratamento eficaz, simples e minimamente invasiva para o sorriso gengival de origem óssea (excesso de crescimento vertical da maxila) (AU).

This study aims to report the case of a patient diagnosed with gummy smile, who was treated with botulinum toxin type A. A female patient, 23 years old, sought dental care reporting dissatisfaction with the amount of gum exposed during smile. The diagnosis was gummy smile with origin in excess of vertical maxillary growth. The orthognathic surgery treatment indicated, when there is smile disharmony due to a bone problem, was promptly rejected by the patient. Thus, it was suggested the application of botulinum toxin type A in order to relax the upper lip levator muscles and the bridge of the nose and upper lip lifts (ELSAN muscles), reducing the gum strip exposed to smile. On the third day after application, the first clinical signs of drug effect was noticed by the patient, who reported maximum effect after 14 days. The patient reported extreme satisfaction with treatment, considering the painless and without side effects procedure. Return visits were conducted with 15, 90, 120, and 150 days. After 120 days, the treatment effect was still present. In the final examination, there was the end of the action of the drug and return to starting position. It was concluded that the botulinum toxin type A has proved to be an alternative effective, simple and minimally invasive treatment for gummy smile of bone origin (excessive vertical maxillary growth) (AU).

RESUMO

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.
