Importancia del diagnóstico precoz en el carcinoma mucoepidermoide. Relato de caso clínico / Importance of early diagnosis in mucoepidermoid carcinoma. Case report

El carcinoma mucoepidermoide es el tumor maligno más frecuente de las glándulas salivales menores localizándose por lo general en el paladar. El objetivo del presente reporte de caso es evidenciar en la literatura científica la importancia del diagnóstico precoz de carcinomas orales, así como, el rol fundamental que cumple el odontólogo general para identificar, guiar y derivar al paciente a un especialista. Se presenta el caso clínico de un paciente de sexo masculino que acudió a la Facultad de Odontología de la Universidad Nacional de Asunción, quien fue derivado por su odontóloga tras percibir un pequeño pero perceptible cambio en la coloración normal de la mucosa y molestias ocasionales en la zona del paladar duro. Al examen intraoral se observó en el paladar duro, a la altura de los premolares en la hemiarcada izquierda, una lesión nodular ovoidea, color violáceo, de 1cm de diámetro, depresible a la palpación. Se realizó una biopsia incisional para su estudio histopatológico, reportando un carcinoma mucoepidermoide. El diagnóstico precoz de este tipo de patologías es un desafío para el odontólogo general, quien debe orientar al paciente, ante cualquier cambio de la estructura normal de la cavidad bucal, para que acuda a un especialista.

Mucoepidermoid carcinoma is the most frequent malignant tumor of the minor salivary glands, usually located in the palate. The objective of this case report is to demonstrate in the Paraguayan scientific literature the importance of early diagnosis of oral carcinomas as well as the fundamental role of the general dentist in identifying, guiding and referring the patient to the corresponding specialist. The clinical case presented is about a male patient who attended the Faculty of Dentistry of the National University of Asuncion. His dentist referred him after noticing a small but perceptible change in the normal coloration of the mucosa and occasional discomfort in the area of the hard palate. In the intraoral examination, an ovoid nodular lesion, purplish in color, 1cm in diameter, depressible on palpation, observed on the hard palate at the level of the premolars in the left hemiarch. An incisional biopsy performed for histopathological study, reporting a mucoepidermoid carcinoma. Regarding the early diagnosis of this type of pathology, the challenge for the general dentist will continues to be his continuous training in order to be able to successfully guide the patient in seeking care from the right specialist in case of any change in the oral cavity.

Mixoma odontogénico de larga data en el maxilar. Reporte de caso / Long-Standing odontogenic myxoma of the maxilla. Case Report

Introducción: el mixoma odontogénico es una neoplasia benigna, poco frecuente, de origen mesenquimal proveniente del órgano dentario, es localmente invasivo y no hace metástasis. Su localización más frecuente es a nivel de la mandíbula y poco frecuente en el maxilar. Objetivo: describir las características que presenta un mixoma odontogénico de larga data en el maxilar. Presentación del caso: paciente de sexo masculino de 23 años de edad, soltero, de profesión comerciante, acude a la Catedra de Patología Bucal de la Facultad de Odontología de la Universidad Nacional de Asunción por presentar una deformidad en la región facial del lado derecho, presente desde la infancia con crecimiento lento sin sintomatología dolorosa. Se realizó una biopsia incisional, tomando una muestra de más de 1 cm de la capsula tumoral para su estudio histopatológico; a partir de la cual se informa sobre un tumor odontogénico mesenquimal compatible con el mixoma odontogénico. Se realizó el tratamiento de una maxilectomía con márgenes de seguridad y el estudio anatomopatológico de todo el tumor extirpado confirmó el diagnóstico de Mixofibroma odontogénico de 2,5 cm de diámetro máximo. Conclusión: un diagnóstico precoz de tumores como los mixomas, que son de crecimiento lento e infiltrante, podría garantizar terapéuticas menos agresivas e invasivas como las del caso presentado, otorgando así mejor pronóstico como calidad de vida a los pacientes.

Introduction: Odontogenic myxoma is a rare benign neoplasm of mesenchymal origin originating from the dental organ, it is locally invasive and does not metastasize. Its most frequent location is at the level of the mandible and infrequently in the maxilla. Objective: To describe the characteristics of a long-standing odontogenic myxoma in the maxilla. Presentation of the case: Male patient, 23 years of age, single, businessman, came to the Department of Oral Pathology of the Faculty of Dentistry of the National University of Asuncion for presenting a deformity in the facial region on the right side, present since childhood with slow growth and no painful symptomatology. An incisional biopsy was performed, taking a sample of more than 1cm of the tumor capsule, for histopathological study; reporting a mesenchymal odontogenic tumor compatible with odontogenic myxoma. A maxillectomy treatment with safety margins performed and the anatomopathological study of the entire excised tumor confirmed the diagnosis of odontogenic myxofibroma with a maximum diameter of 2.5 cm. Conclusion: An early diagnosis of tumors such as myxomas, which are slow-growing and infiltrative, could guarantee less aggressive and invasive therapies such as those in the case presented, thus providing patients with a better prognosis and quality of life.

Impact of different evaluation methods for diagnostic tasks in panoramic radiography / Impacto de diferentes métodos de evaluación durante el diagnóstico en la radiografía panorámica

Abstract The aim of this study was to evaluate the observers diagnostic performance in panoramic radiography using monitor, tablet, X-ray image view box, and against window daylight as a visualization method in different diagnostic tasks. Thirty panoramic radiography were assessed by three calibrated observers for each visualization method, in standardized light conditions, concerning dental caries, widened periodontal ligament space, and periapical bone defects from the four first molars; mucosal thickening and retention cysts in maxillary sinus; and stylo-hyoid ligament calcification and atheroma. A five-point confidence scale was used. The standard-reference was performed by two experienced observers. Diagnostic values using window light were significantly lower for caries and periapical bone defect and retention cyst, stylo-hyoid ligament calcification detection (p<0.05). For atheroma detection, X-ray image view box, tablet, and widow light had lower accuracy than the evaluation on the monitor (p<0.05). Observers diagnostic performances are worsened using window light as an evaluation method for panoramic radiography for dental, sinus, and calcification disorders, while the monitor was the most reliable method.

Resumen El objetivo de este estudio fue evaluar el desempeño diagnóstico de los observadores en la radiografía panorámica utilizando monitor, tablet, caja de visualización de imágenes de rayos X y contra la luz del día de la ventana como método de visualización en diferentes tareas de diagnóstico. Treinta radiografías panorámicas fueron evaluadas por tres observadores calibrados para cada método de visualización, en condiciones de luz estandarizadas, con respecto a caries dental, espacio del ligamento periodontal ensanchado y defectos óseos periapicales de los cuatro primeros molares; engrosamiento de la mucosa y quistes de retención en el seno maxilar; y calcificación y ateroma del ligamento estilohioideo. Se utilizó una escala de confianza de cinco puntos. La referencia estándar fue realizada por dos observadores experimentados. Los valores diagnósticos con luz de ventana fueron significativamente menores para caries y defecto óseo periapical y quiste de retención, detección de calcificación del ligamento estilohioideo (p <0.05). Para la detección de ateroma, la caja de visualización de imágenes de rayos X, el tablet y la luz de viuda tuvieron una precisión menor que la evaluación en el monitor (p <0.05). El rendimiento diagnóstico del observador empeora al utilizar la luz de la ventana como método de evaluación de la radiografía panorámica para los trastornos dentales, de los senos nasales y de la calcificación, mientras que el monitor fue el método más fiable.

Lingual amyloidosis associated to multiple myeloma: case report / Amiloidose lingual associada a mieloma múltiplo: relato de caso

ABSTRACT Oral amyloidosis is a disease characterized by extracellular and irreversible deposition of amorphous and fibrillar proteins in the oral cavity, being strongly associated with Multiple Myeloma. The objective of this study is to report a case of a 62-year-old woman diagnosed with Multiple Myeloma who, approximately 2 years after starting treatment for the underlying disease, presented a lesion on the lateral border of the tongue with exophytic growth, pinkish color, vascularized, painless, measuring 3cm in its largest diameter. After histopathological analysis through incisional biopsy, a final diagnosis of amyloidosis was obtained. As a local treatment, we opted for complete excision of the lesion. The patient evolved to death due to Multiple Myeloma influenced by the diagnosis of systemic amyloidosis. Oral amyloidosis is usually associated with the systemic presentation of the disease, making it necessary to conduct a thorough investigation of other organs. Its diagnosis is important since the prognosis is directly related and can negatively influence survival rates and treatment of the underlying disease.

RESUMO A amiloidose oral é uma doença caracterizada pela deposição extracelular e irreversível de proteínas amorfas e fibrilares na cavidade bucal, sendo fortemente associada com Mieloma Múltiplo. O objetivo deste trabalho é relatar o caso de uma mulher com 62 anos de idade diagnosticada com Mieloma Múltiplo que, aproximadamente 2 anos após o início do tratamento para a doença de base, apresentou lesão em borda lateral de língua com crescimento exofítico, de coloração rósea, vascularizada, indolor, medindo 3 cm em seu maior diâmetro. Após análise histopatológica através de biópsia incisional, obteve-se diagnóstico final de amiloidose. Como tratamento local, optou-se pela exérese completa da lesão. A paciente evoluiu para óbito por consequência do Mieloma Múltiplo com complicações associadas à amiloidose sistêmica. A amiloidose oral geralmente está associada com a apresentação sistêmica da doença, tornando necessária uma investigação aprofundada nos demais órgãos. Seu diagnóstico é importante uma vez que pode influenciar diretamente no prognóstico e, consequentemente, negativamente nas taxas de sobrevida e no tratamento da doença de base.

Epidermal cyst: a rare case report in a 5-month-old child / Cisto epidérmico: relato de caso raro em criança de 5 meses

ABSTRACT The epidermal cyst is a rare, benign lesion, usually asymptomatic and slowly enlarging, more frequently located in the submandibular region. Its etiology is believed to be associated with the epithelial residual tissues retained in the midline during the closure of the first and second brachial arches, in the third and fourth weeks of intra-uterine life. Its clinical characteristics are of a rubbery consistency to palpation, well defined borders, with the absence of skin appendages within their squamous epithelium lined walls. The final diagnosis is confirmed through histopathological examination with stratified squamous epithelium findings in the cystic fluid lumen or keratin. The treatment is usually surgical and without recurrence and the final diagnosis is confirmed through histopathological examination. This paper aims to present a case report of a congenital epidermal cyst in a 5-month-old female patient located in the mouth floor near the sublingual gland duct. The case was treated with excisional biopsy and after follow-up, there was no recurrence.

RESUMO O cisto epidérmico é um cisto de desenvolvimento, benigno, raro, localizado com maior frequência na região submandibular, geralmente assintomático e de evolução lenta. Acredita-se que a sua etiologia esteja associada aos restos epiteliais retidos na linha média durante o fechamento do primeiro e segundo arcos braquiais, na terceira ou quarta semana de vida intrauterina. Suas características clínicas são de uma consistência borrachóide à palpação, bordas delimitadas e sem apêndices de pele no seu interior. O diagnóstico é confirmado através do exame histopatológico com achados de epitélio escamoso estratificado e no lúmen fluído cístico ou queratina. O tratamento é geralmente cirúrgico e sem recidivas. Este trabalho relata um caso de cisto epidérmico congênito de uma paciente pediátrica, do sexo feminino, de cinco meses de idade e localizado no assoalho de boca próximo ao ducto da glândula sublingual. O caso foi tratado com a enucleação cirúrgica e em seis meses de acompanhamento não apresentou recidiva.

Destes casos, 197 (77%) cistos odontogênicos e 58 (23%) tumores odontogênicos foram coletados, sendo que somente um caso (0,39%) possuiu o diagnóstico de neoplasia odonto-gênica maligna. Os diagnósticos mais prevalentes foram cisto radicular (32,5%) e cisto dentígero (31,76%), seguidos de ceratocisto odontogênico (10,98%), odontoma (10%) e ameloblastoma (10%). A maioria dos casos acometeu mandíbula (53,7%), com uma discreta predileção pelo sexo feminino (51%). A média de idade foi de 34±20,53 anos. Discussão: os dados apresentados corroboram com a literatura no que se refere à raridade do diagnóstico de tumores odontogênicos. Conclusão: o presente estudo demonstrou as principais características clínico-pato-lógicas de LOs diagnosticadas em um hospital no sul do Brasil, contribuindo para um maior conhecimento do perfil destas lesões.

Introduction: odontogenic lesions (OLs) represent a heterogeneous group of oral and maxillofacial patho-logies presenting distinct characteristics. The present study aimed to identify the clinical and pathological characteristics of OLs diagnosed in a southern Brazilian hospital. Materials and methods: a retrospective study was performed to evaluate cases with histopathological diagnosis of OLs identified in the period between 2007 and 2017. The patient's medical records were evaluated in order to obtain the clinical and pathological charac-teristics and the histopathological diagnosis from each case. Results: a total of 255 cases of OLs were identified. From these, 197 (77%) odontogenic cysts and 58 (23%) odontogenic tumors were surveyed, with only one case (0,39%) of a malignant odontogenic neoplasm. The most prevalent diagnosis were radicular cyst (32.5%) and den-tigerous cyst (31.76%), followed by odontogenic keratocyst (10.98%), odontoma (10%) and ameloblastoma (10%). The majority of the cases affected the mandible (53.7%) with a slight preference by female individuals (51%). The mean age was 34±20.53 years old. Discussion: the presented data are in accordance with the literature regarding the rarity of the diagnosis of odontogenic tumors.Conclusion: the present study demonstrated the main clinical and pathological characteristics of OLs diagnosed in a southern Brazilian hospital, contrib-uting to a better understanding of these injuries profiles.

Influência de diferentes materiais obturadores endodônticos em imagens de TCFC: uma avaliação in vitro / Influence of different root canal obturation materials in CBCT imaging: an in vitro evaluation

Objetivo: O presente estudo avaliou a influência de materiais obturadores endodônticos na produção de artefato de imagens de tomografia computadorizada de feixe cônico (TCFC), por meio da análise de densidade de imagem em incisivos centrais e dentes pré-molares unirradiculares. Métodos: Os dentes foram submetidos a instrumentação endodôntica e divididos em cinco grupos: um grupo controle (sem preenchimento endodôntico) e quatro grupos teste, cada um preenchido por um material obturador endodôntico diferente (PulpCanal Sealer, AHPlus, Sealer26 e BCSealer). Após a aquisição da TCFC, as imagens foram avaliadas para determinar variações de tons de cinza nos três terços da raiz (análise objetiva). A segunda análise (subjetiva) comparou o grupo controle com dois dos grupos teste, em um processo randomizado. Resultados: Na análise objetiva, o Sealer26 e o BCSealer mostraram diferença estatística para valores mínimos, em comparação com outros materiais obturadores endodônticos, para dentes anteriores e posteriores. Para valores máximos, apenas o grupo controle diferiu estatisticamente dos grupos teste. Ao comparar os valores dos pré-molares e dos incisivos centrais em tons cinza pelo teste de Kruskal-Wallis, foi encontrada diferença estatisticamente significativa para os valores mínimos. Na análise subjetiva, para dentes anteriores e posteriores, o PulpCanal Sealer foi o material mais frequentemente apontado pelos observadores como aquele que produziu mais interferência de artefato. Conclusões: Os materiais obturadores endodônticos nos dentes posteriores apresentaram comportamento semelhante; somente o PulpCanal Sealer no terço apical apresentou diferenças estatísticas em relação aos demais grupos. Para os dentes anteriores, o BCSealer apresentou valores mínimos maiores em relação aos outros materiais obturadores endodônticos, o que poderia representar maior interferência do artefato (AU).

Objective: This study evaluated the influence of canal obturation materials in the production of cone beam computed tomography (CBCT) images artifact, by means of image density analysis and comparison between four materials in central incisors and monoradicular premolar teeth. Materials and Methods: The teeth were submitted to endodontic instrumentation and divided into 5 groups: one control group (no endodontic filling) and four test groups each one filled by a different endodontic sealer (PulpCanal Sealer, AHPlus, Sealer26 and BCSealer). After CBCT scanning, the images were assessed to determine grayscale variations in three root thirds (objective analysis). The second (subjective) analysis compared the control group with two of the test groups in a randomized process. Results: In the objective analysis, Sealer26 and BCSealer showed statistical difference for minimum values, in comparison with another sealers, for both anterior and posterior teeth. For maximum values, only control group differed statistically from test groups. When comparing premolars and central incisors grayscale values by ANOVA analysis, a statistically significant difference was found mainly for minimum values. At the subjective analysis, for both anterior and posterior teeth, PulpCanal Sealer was the filling most frequently appointed by the observers as the one that produced more artifact interference. Conclusion: Endodontic fillings at posterior teeth performed similar behavior. Only PulpCanal Sealer on apical third presented higher maximum values in relation to others groups, which could represent more white brands. For anterior teeth, BC Sealer performed higher minimum values in relation to other endodontic fillings, which could represent more dark bands (AU).

Use of wide-field optical fluorescence for visualization of oral biofilm in a patient with peri-implant mucositis: a new approach / Uso da fluorescência óptica de campo amplo para visualização de biofilme oral em paciente com mucosite peri-implantar: uma nova abordagem

ABSTRACT Peri-implant diseases, caused by bacteria from biofilm related to dental implants, are one of the main causes of late loss of implants. In this sense, peri-implant diseases are divided into peri-implant mucositis, when it affects only the soft tissues, and peri-implantitis, when there is a bone involvement, which can lead to the failure of dental implant therapy. Thus, biofilm removal is essential for peri-implant health, allowing long-term success in implant therapy. To improve the visualization of oral biofilm, which is usually transparent or colorless, disclosing agents have been routinely used. However, disclosing agents have allergenic potential and can cause staining extrinsically in restorative and prosthetic materials, leading to aesthetic impairment. Thus, the use of fluorescence has been studied as an alternative for visualization of oral biofilm. Therefore, this report describes the use of wide-field optical fluorescence for visualization of oral biofilm associated with implants and teeth, in a routine appointment and follow-up of a partially edentulous patient with peri-implant mucositis. In addition, this report showed wide-field optical fluorescence can be used in a clinical routine of care of patients with dental implants. In this sense, wide-field optical fluorescence allowed easy and immediate visualization of the mature oral biofilm for its adequate removal, evaluation of the quality of restoration to sealing of screw access-hole of implant and identification of cariogenic lesions, without risk of allergic reactions or staining of prostheses and restorations.

RESUMO Doenças peri-implantares, causadas por bactérias de biofilme relacionadas a implantes dentários, são uma das principais causas de perda tardia de implantes. Nesse sentido, as doenças peri-implantares são divididas em mucosite peri-implantar, quando afeta apenas tecidos moles, e peri-implantite, quando há comprometimento ósseo, o que pode levar ao fracasso da terapia com implantes dentários. Assim, a remoção do biofilme é essencial para a saúde peri-implantar, permitindo sucesso a longo prazo na terapia com implantes. A fim de melhorar a visualização do biofilme oral, que geralmente é transparente ou incolor, agentes reveladores têm sido rotineiramente utilizados. No entanto, esses agentes têm potencial alergênico e podem causar manchas extrinsecamente em materiais restauradores e protéticos, levando a prejuízo estético. Assim, o uso da fluorescência tem sido estudado como alternativa para visualização do biofilme oral. Este relato descreve o uso da fluorescência óptica de campo amplo para visualização do biofilme oral associado a implantes e dentes em uma consulta de acompanhamento de rotina de uma paciente parcialmente edêntula com mucosite peri-implantar. Além disso, este relato evidenciou que a fluorescência óptica de campo amplo pode ser utilizada dentro da rotina clínica de atendimento de pacientes com implantes dentários. Nesse sentido, a fluorescência óptica de campo amplo permitiu a visualização fácil e imediata do biofilme oral maduro para sua remoção adequada, a avaliação da qualidade da restauração do selamento do orifício de acesso do parafuso do implante e a identificação de lesões cariogênicas, sem risco de reações alérgicas ou manchamento de próteses e restaurações.

ABSTRACT Introduction: Dental surgeons are confronted every day with several cases that require accuracy in the initial diagnosis and attention to the treatment that will be proposed. One of these is amelogenesis imperfecta, a rare hereditary tooth alteration. The main features of amelogenesis imperfecta are hypomineralization or hypoplasia of the enamel matrix resulting in discoloration, sensitivity and fragility of this tissue. Of the existing clinical subtypes, the hypoplastic variant is the most prevalent. Objective: Report and correlate two cases of hypoplastic amelogenesis imperfecta in members of the same family. Case presentation: The diagnosis was based on clinical and radiographic examination, as well as analysis of the correlation between the clinical findings obtained from each patient and other relatives. The treatment plan proposed was therefore multidisciplinary and appropriately consistent with the condition. Conclusions: It is important for dental surgeons to study and be aware of these rare changes to be able to establish an accurate diagnosis. On the other hand, clinical management should be broadened through individualized and/or family planning, paying attention not only to esthetic and functional aspects, but psychological and social as well(AU)
