RESUMO

This case report highlights the delay in the diagnosis of oral squamous cell carcinoma (OSCC) and the inappropriate use of low-level laser therapy (LLLT) in dentistry. OSCC is a malignant neoplasm that affects the oral cavity and can have severe consequences if not diagnosed and treated appropriately and promptly. The patient presented with a persistent oral lesion that was initially diagnosed as a traumatic injury and treated with LLLT, which led to a delay in the correct diagnosis of OSCC. The case emphasizes the importance of early detection and proper management of oral lesions to prevent the progression of malignant conditions. It also emphasizes the need for professional knowledge regarding the applicability of LLLT in dental practice. Dental professionals should be vigilant in recognizing suspicious oral lesions and promptly refer patients for further evaluation and appropriate treatment to ensure optimal outcomes.

Este informe de un caso destaca el retraso en el diagnóstico del carcinoma espinocelular oral (CEC) y el uso inapropiado de la terapia con láser de baja potencia (LBP) en odontología. El CEC es una neoplasia maligna que afecta la cavidad oral y puede tener graves consecuencias si no se diagnostica y trata de manera adecuada y oportuna. La paciente presentó una lesión oral persistente que inicialmente se diagnosticó como lesión traumática y se trató con LBP, lo que llevó a un retraso en el diagnóstico correcto del CEC. El caso enfatiza la importancia de la detección temprana y el manejo adecuado de las lesiones orales para prevenir la progresión de condiciones malignas. También resalta los riesgos asociados con el uso inapropiado de la LBP en la práctica odontológica. Los profesionales de la odontología deben estar atentos a las lesiones orales sospechosas y remitir a los pacientes de manera oportuna para una evaluación adicional y un tratamiento adecuado, con el fin de garantizar mejores resultados.

RESUMO

We report a case of difficult-to-control mycosis fungoides (MF), where the role of the dental surgeon was crucial for the control and prognosis of the disease. A 62-year-old female patient diagnosed with MF had a previous record of red patches and small raised bumps on the face, along with a cancerous growth in the cervical and vulvar region. The patient was initially treated with methotrexate and local radiotherapy without resolution. Chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone was then started (CHOP protocol). The dental team of a reference hospital was consulted to evaluate swelling in the anterior region of the palate, which had been developing for two months, reporting discomfort when eating. The role of the dentistry team was fundamental in the differential diagnosis of oral lesions with dental infections, second neoplasia, or even a new site of disease manifestation, in addition to controlling mucosal changes resulting from chemotherapy. After ruling out dental infection, the dentistry team performed a lesion biopsy to confirm the diagnosis. The histopathological and immunohistochemical analysis showed atypical lymphoid infiltration of T cells (CD3+/CD4+/CD7-/CD8-), coexpression of CD25, and presence of CD30 cells, corresponding to the finding for MF. Identifying CD30 + allowed for a new chemotherapy protocol with brentuximab vedotin (BV) combined with gemcitabine. This protocol effectively controlled MF, which previous protocols had failed to do. The diagnosis by the dental team was essential for therapeutic change and improvement of the patient's clinical condition without the need for invasive medical procedures.

RESUMO

Telediagnosis uses information and communication technologies to support diagnosis, shortening geographical distances. It helps make decisions about various oral lesions. The objective of this scoping review was to map the existing literature on digital strategies to assist in the diagnosis of oral squamous cell carcinoma. this review was structured based on the 5-stage methodology proposed by Arksey and O'Malley, the Joanna Briggs Institute Manual for Evidence Synthesis and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. The methods were registered on the Open Science Framework. The research question was: What digital strategies have been used to assist in the diagnosis of oral squamous cell carcinoma? The search was conducted on PubMed/MEDLINE, Scopus, Web of Science, Embase, and ScienceDirect. Inclusion criteria comprised studies on telediagnosis, teleconsultation or teleconsultation mediated by a professional and studies in English, without date restrictions. The search conducted in June 2023 yielded 1,798 articles, from which 16 studies were included. Telediagnosis was reported in nine studies, involving data screening through applications, clinical images from digital cameras, mobile phones or artificial intelligence. Histopathological images were reported in four studies. Both, telediagnosis and teleconsultation, were mentioned in seven studies, utilizing images and information submission services to platforms, WhatsApp or applications. One study presented teleconsultations involving slides and another study introduced teleconsultation mediated by a professional. Digital strategies telediagnosis and teleconsultations enable the histopathological diagnosis of oral cancer through clinical or histopathological images. The higher the observed diagnostic agreement, the better the performance of the strategy.

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

El conocimiento de la patología oral, y su correcto diagnóstico es fundamental en Odontología, puesto que un diagnóstico tardío, particularmente en casos de lesiones premalignas o malignas, pueden conducir a serias consecuencias para el paciente. El objetivo de este trabajo fue establecer la congruencia diagnóstica clínica - histopatológica de lesiones en cavidad oral en pacientes que asistieron a la Facultad de Odontología, Universidad de Costa Rica, y a quienes se les realizó biopsia de la lesión, durante el período 2016-2019. El estudio fue descriptivo y retrospectivo, basado en datos de reportes histopatológicos en la población mencionada, por presentar alguna lesión, de tejidos blandos o duros, en cavidad oral. La muestra estadística fue por conveniencia, no probabilística y no aleatoria. Las técnicas estadísticas utilizadas fueron descriptivas para el análisis de la información, el cual se basó en la distribución de frecuencias y cruce de variables. El procesamiento estadístico de los datos se diseñó en una base de datos creada en Excel. La muestra comprendió 160 reportes histopatológicos de los cuales se excluyeron 14. La edad promedio de los pacientes fue 42 años (rango 2 - 78 años). La proporción hombre: mujer correspondió 1:1.4, predominado el sexo femenino en 58,9 %. La congruencia del diagnóstico histopatológico con el diagnóstico clínico correspondió a 55,8 %. La congruencia de los diagnósticos demuestra el conocimiento del profesional en identificar la lesión clínicamente de forma correcta, lo que permite actuar en el momento preciso y confirmar la impresión clínica diagnóstica de una patología mediante el estudio histopatológico, el cual es el estándar oro. El problema radica en aquellos casos en que hay discrepancia diagnóstica, pues exige conocer los factores responsables de esta discrepancia, exige la búsqueda de soluciones y exige reforzar y redireccionar la formación académica del profesional y de los estudiantes para reconocer y describir estas lesiones.

Knowledge of oral pathology and its correct diagnosis is fundamental in Dentistry, since a late diagnosis, particularly in cases of premalignant or malignant lesions, can lead to serious consequences for the patient. The objective of this study was to establish the clinical- histopathological diagnostic consistency of lesions in the oral cavity in patients who attended the Faculty of Dentistry, Universidad de Costa Rica, and who underwent a biopsy of the lesion, during the period 2016-2019. The study was descriptive and retrospective, based on data from histopathological reports in the mentioned population, due to presenting some lesion, soft or hard tissue, in the oral cavity. The statistical sample was for convenience, non- probabilistic nor random. The statistical techniques used were descriptive for the analysis of the information, which was based on frequency distribution and crossing of variables. The statistical processing of the data was designed in a database created in Excel. The sample collects 160 histopathological reports, of which 14 were excluded. The average age of the patients was 42 years (range between 2 - 78 years old).The male:female ratio corresponded to 1:1.4, with a predominance of the female sex at 58.9 %.The congruence of the histopathological diagnosis with the clinical diagnosis corresponded to 55.8 %. Diagnostic consistency demonstrates knowledge of the professional in correctly identifying the lesion clinically, which allows acting at the precise moment and confirming the diagnostic clinical impression of the pathology via histopathological study which is the gold standard. The problem lies in those cases in which there is a diagnostic discrepancy, since it requires having knowledge of the underlying factors and therefore, requires searching for solutions, reinforcing and redirecting the academic training of professionals and students to recognize and describe these lesions.

RESUMO

In recent years, teledentistry has gained visibility, especially because of the COVID-19 pandemic. Concerning oral medicine, there is great expectation, particularly about its potential to promote early diagnosis of oral lesions. In southern Brazil, two initiatives have shown a positive influence on each other and have led to greater awareness of oral cancer and more access to qualified advice on diagnosing and managing oral lesions. Although the contributions of this approach are promising, there are barriers to be overcome.

RESUMO

Carcinoma cuniculatum (CC), is a rare well-differentiated, low-grade variant of squamous cell carcinoma. However, diagnosis of oral CC has remained very difficult, because many pathologists and clinicians remain un acquainted with oral CC, because there are very few reported cases of this disease in the oral cavity. To our knowledge, no more than 60 head and neck cases have been reported since Flieger and Owinski first described a case involving the mandible in 1977, because there are very few published cases of this disease in the oral cavity, the aim of this report is to provide a detailed clinical and histopathologic description of carcinoma cuniculatum of the maxila, provide a brief review of the literature, and highlight the difficulties in arriving at the correct diagnosis.

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

Objetivos: Instruir e orientar ao cirurgião dentista e demais profissionais de saúde a importância da detecção e rastreio precoce de lesões pré-malignas. Revisão de Literatura: O Líquen Plano Oral é uma condição dermatológica crônica, de origem auto-imune, relativamente comum na população, que atinge o epitélio de mucosa e pele, sendo considerada, pela Organização Mundial de Saúde (OMS), uma desordem potencialmente maligna quando associado a áreas de ulceração. A revisão de literatura foi realizada nas bases de dados PubMed e Lilacs. Buscamos investigar o potencial de malignização do Líquen Plano Oral associado a condições erosivas, analisando o processo de carcinogênese no processo inflamatório. Conclusão: Conclui-se que o objeto de estudo ainda é um assunto pouco explorado pela literatura, porém há indícios etiopatológicos que enfatizam o processo de malignização oriundo de uma lesão pré-maligna como o Líquen Plano Oral. Além disso, enfatizamos a importância do diagnóstico precoce das lesões estomatognáticas, para que assim possamos aumentar as chances de cura do paciente.(AU)

Objectives: To instruct and guide dentists and other health professionals on the importance of early detection and screening of pre-malignant lesions. Literature Review: Oral Lichen Planus is a chronic dermatological condition, of autoimmune origin, relatively common in the population, which affects the epithelium of the mucosa and skin, being considered, by the World Health Organization (WHO), a potentially fatal disorder. malignant when associated with areas of ulceration. A literature review was performed on the PubMed and Lilacs databases. We sought to investigate the potential for malignancy of Oral Lichen Planus associated with erosive conditions, analyzing the process of carcinogenesis in the inflammatory process. Conclusion: It is concluded that the object of study is still a subject little explored in the literature, but there are etiopathological accusations that emphasize the process of malignancy arising from a pre-malignant lesion such as Oral Lichen Planus. In addition, we emphasize the importance of early diagnosis of stomatognathic lesions, so that we can increase the patient's chances of cure.(AU)

RESUMO

OBJECTIVES: The objective of this systematic literature review was to provide a complete panorama of the oral manifestations of Huntington's disease (HD). MATERIALS AND METHODS: Databases were searched, and original research studies or case report manuscripts up to May 2021 were included using keywords that describe HD combined with words related to oral health; MeSH terms were used exclusively. No time or language restrictions were applied. RESULTS: Twenty-two investigations (12 original articles and 10 case reports) regarding oral manifestations of HD were included. The subjects examined in the selected research articles were dental health, coordination of oral structures, speech, dysphagia, and swallowing alterations. The case reports described dental treatment procedures, oromandibular dyskinesia, dysphagia, and speech alterations. CONCLUSIONS: The oral manifestations of HD were found to be associated with the advance of the disease in that the more severe the HD, the worse the alterations affecting the oral cavity. Dysphagia, dysarthria, masticatory problems, oral health impairment, and choreiform movements involving the tongue and other orofacial muscles were the main manifestations of HD in the oral cavity. The PROSPERO systematic review registration number of this study is CRD42021238934.
