RESUMO

Introducción: Estudios previos han reportado que pacientes infectados con el virus del COVID-19, podrían manifestar sintomatologías a nivel de la cavidad oral. Objetivo: Evaluar la frecuencia de manifestaciones orales asociadas a COVID-19 en un segmento de la población paraguaya y determinar cuáles son las más prevalentes. Metodología: Estudio descriptivo de corte transversal. Fue realizada una encuesta electrónica de enero a marzo del 2022. Los datos fueron presentados como frecuencias y porcentajes y analizados mediante la prueba de chi-cuadrado. El análisis estadístico se realizó con el software R versión 4.0.3. Resultados: La muestra estuvo compuesta por 478 personas. El 79,50 % correspondió al sexo femenino y el 45,19 % tenía entre 25 y 34 años. El 65,48 % informó haber experimentado al menos 1 síntoma o signo oral durante el curso de COVID-19. La pérdida de la sensación de sabores amargos, seguida de la alteración del sabor de los alimentos y la pérdida de la percepción dulce, fueron los síntomas más comunes. Se encontró una proporción significativamente mayor de manifestaciones orales en el rango de 18-24 años (χ²; p= 0,003). Entre las personas que desarrollaron COVID-19 de forma moderada a severa hubo mayor número de manifestaciones de síntomas orales (χ²; p= 0,044). Discusión: Se identificó una alta frecuencia de manifestaciones orales en pacientes con casos de moderados a severos de COVID-19, destacándose los trastornos del gusto como los más predominantes. Los individuos más jóvenes fueron los más afectados.

Introduction: Previous studies have reported that patients infected with the COVID-19 virus could manifest symptoms in the oral cavity. Objective: To evaluate the frequency of oral manifestations associated with COVID-19 in a segment of the Paraguayan population and determine the most prevalent ones. Methods: Descriptive cross-sectional study. An electronic survey was conducted from January to March 2022. The data were presented as frequencies and percentages and analyzed using the chi-square test. Statistical analysis was performed with R software version 4.0.3. Results: The sample consisted of 478 individuals. 79.50% were female, and 45.19% were between 25 and 34 years old. 65.48% reported having experienced at least 1 oral symptom or sign during the course of COVID-19. The loss of the sensation of bitter tastes, followed by the alteration of the taste of foods and the loss of sweetness perception, were the most common symptoms. A significantly higher proportion of oral manifestations was found in the 18-24 age range (χ²; p= 0.003). Among people who developed COVID-19 in a moderate to severe form, a greater number of oral symptom manifestations were observed (χ²; p= 0.044). Discussion: A high frequency of oral manifestations was identified in patients with moderate to severe cases of COVID-19, with taste disorders standing out as the most predominant. Younger individuals were the most affected.

RESUMO

O câncer (CA) de boca representa um problema de saúde pública a nível mundial, com altas taxas de morbimortalidade. A desvalorização das lesões iniciais pelo profissional, somada à incapacidade técnica de reconhecimento dessas lesões, a demora do atendimento, erros no diagnóstico inicial, assim como a ausência de campanhas sobre a doença e seus fatores de risco, são fatores que diminuem as chances de diagnóstico do CA de boca em seus estágios iniciais. Para realização do diagnóstico precoce das lesões potencialmente malignas ou suspeitas de malignidade, é fundamental contar com uma rede de atenção à saúde estruturada e organizada, com profissionais capacitados para identificar as lesões em estágio inicial e realizar a biópsia para fins diagnósticos e posterior análise em laboratório que possua profissional especializado em anatomia patológica. O presente estudo teve como objetivo discutir o papel e desempenho dos Centros de Especialidades Odontológicas (CEOs) em relação ao procedimento de coleta de biópsia de tecidos moles da boca no Estado do Rio de Janeiro, com finalidade diagnóstica, considerando seu papel na oferta deste procedimento. Trata-se de uma pesquisa descritiva e exploratória acerca do papel e desempenho dos CEOs com foco na oferta do exame de diagnóstico do CA de boca por estes centros, no período de 2017 a 2019. Os resultados apontam que os CEOs possuem um papel central para o diagnóstico do câncer de boca, mas aquém do que potencialmente poderia ofertar já que não houve produção de biópsias em 47 (57%) dos 82 CEOs existentes, no período analisado. Um dos limites do trabalho foi a incapacidade de avaliação dos sistemas de apoio, assim como a contribuição dos serviços de saúde das universidades para as análises desses exames devido a insuficiência de dados públicos sobre os exames anatomopatológicos específicos para o câncer de boca. Tais resultados buscam fornecer subsídios para que os gestores de saúde possam otimizar o fluxo dos usuários através da organização e do fácil acesso à rede, identificando e solucionando dificuldades enfrentadas por estes centros para a realização destes procedimentos, reduzindo atrasos na investigação diagnóstica e no tratamento desta patologia.

Mouth cancer (CA) represents a public health problem worldwide, with high morbidity and mortality rates. The devaluation of initial injuries by the professional, combined with the technical inability to recognize these injuries, as well as the delay in public assistance, errors in the initial diagnosis, as well as the lack of campaigns about the disease and its risk factors, are factors that reduce the chances diagnosis of oral CA in its initial stages. To carry out early diagnosis of potentially malignant and suspected malignant lesions, it is essential to have a structured and organized health care network, with professionals trained to identify lesions at an early stage and perform biopsy for diagnostic purposes and subsequent analysis in the laboratory. that has a professional specialized in pathological anatomy. In this sense, the present study aimed to discuss the role and performance of Dental Specialty Centers (CEOs) in relation to the procedure for collecting soft tissue biopsies from the mouth in the State of Rio de Janeiro, with diagnostic purposes, considering their role in offering this procedure. The study is a descriptive and exploratory research on the role and performance of CEOs with a focus on offering diagnostic examinations for oral CA by these centers, from 2017 to 2019. The results indicate that CEOs have a central role in the diagnosis of oral cancer, but below what they could potentially offer as there was no production of biopsies in 47 CEOs (57%) of the 82 existing CEOs in the period analyzed. One of the limits of the work was the inability to evaluate support systems, as well as the contribution of university health services to the analysis of these exams due to insufficient public data on specific anatomopathological exams for oral cancer. Such results seek to provide support so that health managers can optimize the flow of users through the organization and easy access to the network, identifying and resolving difficulties faced by these centers in carrying out these procedures, reducing delays in diagnostic investigation and treatment of this condition.

RESUMO

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.

RESUMO

Introdução: A radiopacidade é um requisito importante para um material odontológico, pois permite que as estruturas dentárias sejam distinguidas do material substituto, facilitando o diagnóstico radiográfico. Portanto, com o surgimento de novas formulações de materiais endodônticos, é fundamental que esta propriedade esteja em conformidade com as normas vigentes. Objetivo: Avaliar as radiopacidades dos cimentos MTA Angelus Branco, MTA Repair HP e Biodentine entre si e compará-las com as das estruturas dentais humanas, por meio de radiografia digital. Material e Métodos: Foram confeccionados cinco corpos de prova para cada cimento estudado. Cada amostra foi radiografada, pelo método digital, juntamente com uma fatia de um dente molar inferior humano hígido e uma escala de densidade de alumínio (Al). Para cada conjunto, três imagens foram obtidas e avaliadas quanto às densidades por meio da ferramenta histograma do software Image J. Em cada estrutura avaliada, foi usada uma região de interesse pré-definida e as densidades foram apresentadas utilizando-se médias, desvios-padrões e medianas. Para avaliar a normalidade dos dados e comparar a radiopacidade dos três cimentos testados, foram aplicados os testes de Shapiro-Wilk e o de Kruskal-Wallis, respectivamente. Foi utilizado o programa SPSS com nível de significância de 5% (p≤0,05). Resultados: Foi observado para o esmalte e a dentina radiopacidades equivalentes a 2 mm de Al e 1 mm respectivamente. Ambos os cimentos MTA Branco e MTA Repair HP, apresentaram radiopacidade equivalente a 3 mm de Al. O cimento Biodentine apresentou radiopacidade inferior aos demais materiais (2 mm de Al). Conclusão: As radiopacidades dos cimentos MTA Branco e MTA Repair HP foram semelhantes entre si e maiores que às da dentina e do esmalte dental. Em contrapartida, a radiopacidade do cimento Biodentine foi inferior às do MTA Branco e MTA Repair HP, e semelhante à do esmalte.

Introduction: Radiopacity is an important requirement for a dental material, as it allows tooth structures to be distinguished from the substitute material, facilitating radiographic diagnosis. Therefore, with the emergence of new formulations of endodontic materials, it is essential that this property complies with current regulations. Objective: To evaluate the radiopacities of MTA Angelus White, MTA Repair HP and Biodentine cements among themselves and compare them with those of human dental structures, using digital radiography. Material and Methods: Five specimens were made for each studied cement. Each sample was radiographed, using the digital method, along with a slice of a sound human lower molar tooth and an aluminum (Al) density scale. For each set, three images were obtained and evaluated for densities using the histogram tool of the Image J software. In each evaluated structure, a predefined region of interest was used and the densities were presented using means, standard deviations and medians. To assess data normality and compare the radiopacity of the three cements tested, the Shapiro-Wilk and Kruskal-Wallis tests were applied, respectively. The SPSS program was used with a significance level of 5% (p≤0.05). Results: Radiopacities equivalent to 2 mm of Al and 1 mm of Al, respectively, were observed for enamel and dentin. Both MTA Branco and MTA Repair HP cements presented radiopacity equivalent to 3 mm of Al. Biodentine cement presented lower radiopacity than the other materials (2 mm of Al). Conclusion: The radiopacities of MTA Branco and MTA Repair HP cements were similar to each other and greater than those of dentin and dental enamel. In contrast, the radiopacity of Biodentine cement was lower than that of White MTA and MTA Repair HP, and similar to that of enamel.

RESUMO

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.

RESUMO

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.

A todos los pacientes se les realizó teleconsulta por parte de un estomatólogo y se recopilaron los datos relevantes como edad, sexo, antecedentes de enfermedades preexistentes, tipo de lesión estomatológica presente, sitio y sintomatología, entre otros. Todos los pacientes firmaron un consentimiento informado. Resultados. De los 11 casos positivos para SARS-CoV-2, el 63,63% de los pacientes corresponden al sexo femenino (n=7) y 36,36% (n=4) sexo masculino. El 100% de los pacientes fueron diagnosticados por pruebas moleculares y serológicas; así, el 90,90% se diagnosticaron con PCR viral y 9,09% diagnosticado por prueba para antígeno. Las lesiones ulcerativas predominaron en el 54,54%; seguidas de pseudoplaca y eritema en 18,18% respectivamente. Las vesículas y costras se presentaron en el 9,09% respectivamente. El 72,72 (n=8) presentó ageusia y anosmia, y el 45,45 % (n=5) manifestaron comorbilidades como diabetes, hipertensión arterial e hipotiroidismo. Conclusiones. Esta enfermedad viral cursa con lesiones bucales y muchas veces es la primera e incluso la única manifestación que se presenta durante su curso, por eso es importante tener en cuenta e identificar estas lesiones y saber su relación con el manejo terapéutico, compromiso inmunológico o la propia enfermedad.

Objective. To identify and describe the oral lesions found in patients with SARS-CoV-2 infection. Methods. Series of cases with description of 11 patients with SARS-CoV-2 infection confirmed by nasopharyngeal swab or serological test to confirm the infection; with the presence of intraoral manifestations of different types. All patients underwent tele-consultation by a stomatologist and relevant data such as age, sex, history of pre-existing diseases, type of stomatological lesion present, site and symptomatology, among others, were collected. All patients signed an informed consent form. Results. Of the 11 positive cases for SARS-CoV-2, 63.63% (n=7) of the patients were female and 36.36% (n=4) were male. All patients (100%) were diagnosed by molecular and serological tests, 90.90% were diagnosed by viral PCR and 9.09% were diagnosed by antigen test. Ulcerative lesions predominated in 54.54%; followed by pseudoplaque and erythema in 18.18% of patients, respectively. Vesicles and crusts were present in 9.09% respectively. Ageusia and anosmia were present in 72.72 (n=8), and 45.45% (n=5) of patients showed comorbidities such as diabetes, arterial hypertension and hypothyroidism. Conclusions. This viral disease presents with oral lesions and it is usually the first and even the only manifestation during its course. That is why it is important to take into account and identify these lesions, and know their relationship with the therapeutic management, immunological compromise or the disease itself.
