Oral lesions after infection by SARS CoV 2: two case reports / Lesiones bucales posteriores a infección por SARS CoV 2 presentación de dos casos

Introduction: The SARS CoV 2 infection has resulted in several health, economic, and social crises in all areas. The disease shows a substantial biological diversity in humans causing a series of sequels in the trans- or post-infection period in the entire organism. Case Report: The manifestations that occur in the oral cavity and pharynx have not been evaluated. In this study, two clinical cases are reported. The first patient, a 67-year-old male, presents erosive lesions on the dorsal surface of his tongue after SARS CoV 2 infection. Results: Therapy consisting of reinforcing oral cleaning, use of antifungal solutions, mouthwashes containing superoxidation solution and B complex was given to the patient. The reported lesions improved satisfactorily. The second case, a 47-year-old male patient, presented vesiculobullous lesions on the lingual and labial mucosa accompanied by severe painful symptoms after SARS CoV 2 infection. An incisional biopsy was performed. The histopathological result was compatible with pemphigus vulgaris, and the treatment protocol was started with 0.1% topical mometasone and 2g miconazole gel, observing adequate involution of the lesions after 20 days. Conclusions: The aim of this study is to report on the lesions affecting the oral cavity and pharynx in post-COVID patients with the aim of carrying out a thorough intraoral examination, establishing a clinical or histopathological diagnosis to implement a specific treatment plan in each case to improve the health and quality of life of the patients. Keywords: SARS-CoV-2; Oral manifestations; Oral ulcer; Pemphigus; Mouth; Mucous membrane.

Tratamento de trauma por mordedura autoinflingida com laserterapia e bandagem elástica: relato de caso / Bite trauma treatment with laser therapy and elastic bandage: case report

Introdução: trauma de mordedura ou úlcera traumática é uma lesão aguda da mucosa oral que tem como etiologia um trauma mecânico ou irritação no tecido mole afetado. Objetivo: relatar um tratamento multidisciplinar de trauma por mordedura autoinflingida em lábio inferior. Relato do caso: paciente com 17 anos de idade, sexo masculino, paraplégico, ficou acamado devido às limitações neuromotoras e, de forma involuntária e reflexa, realizava a mordedura dos lábios. Essa movimentação traumatizava a região do lábio inferior causando a úlcera traumática, que não cicatrizava. Inicialmente foi instalado um protetor bucal de etil vinil acetato, mas o paciente não se adaptou. Então, foi realizado três sessões de laserterapia (fotobiomodulação), semanalmente e de forma pontual, ao longo da úlcera traumática, nas radiações vermelha e infravermelha (660nm; 808nm; 100mW; 2J/cm2 ­ Laser DUO MMO), aliado às bandagens elásticas (o método Therapy Taping®) para evitar a invaginação para cavidade bucal, afastando o lábio inferior dos dentes a fim de evitar o trauma da mucosa oral. Conclusão: a apresentação desse relato demonstrou algumas possibilidades de tratamento de uma lesão traumática, sendo o seu manejo ainda um grande desafio clínico na Odontologia e em especial para pacientes com deficiências motoras e ou cognitivas.

Introduction: bite trauma or traumatic ulcer is an acute injury of the oral mucosa whose etiology is mechanical trauma or irritation of the affected soft tissue. Objective: to report a multidisciplinary treatment of self-inflicted lower lip trauma. Case report: 17-year-old male patient, paraplegic, was bedridden due to neuromotor limitations and, involuntary and reflexive, bit the lips. This movement traumatized the region of the lower lip causing the traumatic ulcer, which did not heal. Initially, an ethyl vinyl acetate mouthguard was installed, but the patient did not adapt. Then, three sessions of laser therapy (photobiomodulation) was performed weekly and point, along the traumatic ulcer, in red and infrared radiation (660nm; 808nm; 100mW; 2J/cm2 ­ Laser DUO MMO), combined with elastic bandages (the Therapy Taping® method) to prevent invagination into the oral cavity, to move the lower lip away from his teeth in order to avoid trauma to the oral mucosa. Conclusion: the presentation of this report demonstrated some possibilities for the treatment of a traumatic injury, and its management is still a major clinical challenge in Dentistry, especially for patients with motor and/or cognitive impairments.

Traumatic ulcerative granuloma with stromal eosinophilia, an unusual clinical manifestation in the oral mucosa: case report / Granuloma ulcerativo traumático con eosinofilia estromal, una manifestación clínica inusual en la mucosa oral: reporte de un caso

Introduction: Traumatic ulcerative granuloma with stromal eosinophilia is an uncommon condition of the oral mucosa with a chronic course, usually affecting the tongue. Case Report: Clinically it presents as a chronic ulcer, with raised and indurated borders, rarely presented as a tumor. Histologically it shows a diffuse mixed inflammatory infiltrate, rich in eosinophils. The etiology of this lesion is still unclear; however, chronic irritation from traumatic agents is considered a major initiating factor. In some cases, the presence of CD30+ mononuclear cells within the lesions suggest the possibility of a CD30+ lymphoproliferative disorder. This article presents a case of a traumatic ulcerative granuloma with stromal eosinophilia manifested in a 56-year-old female with a solitary ulcerated tumor inside the right cheek. Conclusion: It was diagnosed based on clinical data and histopathological features. In a brief literature review, the entity has been characterized, analyzing its etiology and nature.

Introducción: El granuloma ulcerativo traumático con eosinofilia estromal es una afección infrecuente de la mucosa oral de curso crónico, que suele afectar a la lengua. Case Report: Clínicamente se presenta como una úlcera crónica, con bordes elevados e indurados, rara vez se presenta como un tumor. Histológicamente muestra un infiltrado inflamatorio mixto difuso, rico en eosinófilos. La etiología de esta lesión aún no está clara; sin embargo, la irritación crónica por agentes traumáticos se considera un factor de iniciación importante. En algunos casos, la presencia de células mononucleares CD30 + dentro de las lesiones sugiere la posibilidad de un trastorno linfoproliferativo CD30+. En este artículo se presenta el caso de un granuloma ulcerativo traumático con eosinofilia estromal que se manifiesta en una mujer de 56 años con un tumor ulcerado solitario en el interior de la mejilla derecha. Conclusión: Se diagnosticó con base en datos clínicos y características histopatológicas. En una breve revisión de la literatura se ha caracterizado la entidad, analizando su etiología y naturaleza.

Presentación faríngea de la sífilis secundaria: a propósito de un caso / Pharyngeal presentation of secondary syphilis: a case report

RESUMEN La sífilis es una infección de transmisión sexual causada por la bacteria Treponema pallidum. En los últimos años ha habido un aumento en la incidencia de esta enfermedad debido a la creciente infección por el virus de la inmunodeficiencia humana (VIH) e inmunodepresión. Conocida como "la gran imitadora" son muchos los signos y síntomas que puede simular, siendo la presentación orofaríngea infrecuente. Presentamos el caso de un varón de 31 años de edad que acude a nuestro servicio por clínica de otitis media serosa bilateral. En la exploración física se objetiva una masa en cavum y una ulceración en pared faríngea posterior que se biopsia en consultas externas siendo el resultado un intenso infiltrado inflamatorio crónico de probable origen infeccioso, por lo que se decidió tomar una nueva biopsia bajo anestesia general. El día de la intervención, el paciente refirió la aparición de un exantema eritematoso generalizado, pero de predominio palmo-plantar. Interrogado sobre sus antecedentes, el paciente reconoció conductas sexuales de riesgo y ser portador VIH, por lo que se orientó el diagnóstico hacia una probable sífilis secundaria que se confirmó posteriormente mediante serología. Las lesiones de orofaringe, la masa del cavum y el exantema remitieron con tratamiento antibiótico y corticoideo pautado. Cuando las manifestaciones de cabeza y cuello constituyen la presentación inicial de la sífilis, su diagnóstico se retrasa con frecuencia debido al desconocimiento por parte del médico de primaria, e incluso del otorrinolaringólogo, de las formas típicas de presentación en esta localización. Su diagnóstico precoz es fundamental para prevenir la extensión de la enfermedad.

ABSTRACT Syphilis is a sexually transmitted infection caused by the bacteria Treponema pallidum. Over the last years there has been an increase of the incidence of this disease due to the growing infection by the human inmunodeficiency virus (HIV) and the inmunosupression. Known as "the great imitator", there are many signs and symptoms that can simulate, being the oropharyngeal presentation infrequent. We present the case of a 31-year-old man who came to our service for bilateral otitis media. Physical examination revealed a mass in the cavum and ulceration in the posterior pharyngeal wall that was biopsied in the outpatient clinic. The result was an intense chronic inflammatory infiltrate of probable infectious origin, so it was decided to take a new biopsy under general anesthesia. On the day of the intervention, the patient reported the appearance of a generalized erythematous rash, but predominantly on the bottoms of the feet and on the palms of the hands. Questioned about his background, the patient recognized risky sexual behavior and being an HIV carrier, so the diagnosis was oriented towards a probable secondary syphilis that was subsequently confirmed by serology. The ulcerations of the oropharynx, the mass of the cavum and the rash subsided with antibiotic treatment and corticoid regimen. When the manifestations of the head and neck are the initial presentation of syphilis, its diagnosis is often delayed due to the lack of knowledge of the physicians of the typical presentation forms in this location. Early diagnosis is essential to prevent the spread of the disease and its complications.

The link between ankylosing spondylitis and oral health conditions: two nested case-control studies using data of the UK Biobank

Abstract Ankylosing Spondylitis (AS) is an inflammatory rheumatic disease that affects the axial skeleton and the sacroiliac joints. Recent studies investigated the link between AS and oral diseases, particularly periodontitis. Others suggested that periodontitis may have a role in the pathogenesis of rheumatic diseases. Objective: The aim of this study is to investigate the association between AS and oral conditions. Material and Methods: This research was conducted using the UK Biobank Resource under Application Number 26307. The UK Biobank recruited around 500000 participants throughout Great Britain. Clinical records were available for 2734 participants. Two case-control studies were conducted based on whether AS was self-reported or clinically diagnosed. Oral conditions were identified using self-reported reports of oral ulcers, painful gums, bleeding gums, loose teeth, toothache, and dentures. The association between AS and oral conditions was assessed using logistic regression adjusted for age, gender, educational level, smoking status, alcohol consumption, and body mass index. Results: A total of 1307 cases and 491503 control participants were eligible for the self-reported AS study. The mean age was 58 years for the cases [7.5 standard deviation (SD)] and 57 years for the control groups (8.1 SD). Also, 37.1% of the cases and 54.2% of the control participants were females. Among the oral conditions, only oral ulcers were strongly associated with AS [1.57 adjusted odds ratio (OR); 95% confidence interval (CI) 1.31 to 1.88]. For the study of clinically diagnosed AS, 153 cases and 490351 control participants were identified. The mean age for both cases and control groups was 57 years; 7.6 SD for the cases and 8.1 for the control group. Females corresponded to 26.1% of the cases, and 54.2% of the control participants. Clinically diagnosed AS was associated with self-reported oral ulcers (2.17 adjusted OR; 95% CI 1.33 to 3.53). Conclusion: Self-reported and clinically diagnosed AS populations have increased risk of reporting oral ulcers. Further investigations are required to assess the link between a specific type of oral condition and AS.

Therapeutic effect of Aloe vera and silver nanoparticles on acid-induced oral ulcer in gamma-irradiated mice

Abstract Radiation combined injury, a life-threatening condition, has higher mortality than simple radiation injury. The aim of the present study was to analyze the efficiency of Aloe vera and silver nanoparticles in improving the healing of ulcerated oral mucosa after irradiation. Thirty male Albino mice were divided into five groups: control, radiation, Aloe vera (AV), silver nanoparticles (NS), and AV+NS. The mice were exposed to whole body 6Gy gamma-radiation. After one hour, 20% acetic acid was injected into the submucosal layer of the lower lip for ulcer induction. The animals received topical treatment with the assigned substances for 5 days. Lip specimens were subjected to hematoxylin and eosin and anti alpha-smooth muscle actin immunohistochemical staining. Results demonstrated occurance of ulcer three days post irradiation in all groups except in the AV+NS group where only epithelial detachment was developed. After seven days, data revealed persistent ulcer in radiation group, and almost normal epithelium in the AV+NS group. A significant reduction of epithelial thickness was detected in all groups at the third day as compared to control. At the seventh day, only the AV+NS group restored the epithelial thickness. Area percent of alpha-smooth muscle actin expression was significantly decreased in radiation group at the third day followed by significant increase at the seventh day. However, all treatment groups showed significant increase in alpha-smooth muscle actin at the third day, which decreased to normal level at the seventh day. Our study demonstrated the efficiency of Aloe vera and silver nanoparticles in enhancing ulcer healing after irradiation.

Manifestaciones orales de lupus eritematoso sistémico: a propósito de un caso / Oral clinical features of systemic lupus erythematosus a clinical case

El Lupus Eritematoso Sistémico (LES) es una enfermedad crónica autoinmune con múltiples manifestaciones clínicas, que pueden ir desde el decaimiento general con presencia de lesiones cutáneas, hasta un compromiso sistémico severo afectando diversos órganos. Como en otras enfermedades de este tipo, puede verse comprometida la mucosa oral presentando zonas eritematosas, erosiones y úlceras, como también lesiones blancas discoideas, manifestaciones que se observan más intensas cuanto más descompensado se halla el cuadro general. Se presenta el caso de una paciente joven con diagnóstico de LES desde hace tres años, portadora de lesiones faciales, labiales y gingivitis asociada a Biofilm bacteriano y otros factores locales contribuyentes. Es importante que los cirujano-dentistas estén atentos a las manifestaciones que el LES puede presentar en la boca, como una de sus primeras evidencias clínicas, y así contribuir a su diagnóstico oportuno, derivando al enfermo al médico especialista. De igual forma, es importante que el médico considere el tratamiento de las lesiones orales, que suelen afectar de forma importante la calidad de vida de estos enfermos.

Systemic lupus erythematosus is a chronic auto-immune disease with multiple clinical expressions varying from feeling generally run down with cutaneous lesions to severe systemic compromise affecting several organs. As with similar diseases there may be involvement of the oral mucosa, with areas of erythema, erosions and ulcers as well as white discoid lesions, all more pronounced with increasing disease severity. We present the case of a young girl diagnosed with systemic lupus erythematosus three years before who presented facial, lip and gingival lesions associated with bacterial biofilm and other contributing local factors. It is important that dental surgeons be aware of the possibility of finding systemic lupus erythematosus lesions in a patient´s mouth, it being one of the first signs of the disease, thereby helping to reach a timely diagnosis by referring the patient to a specialist. Similarly, the physician should consider treating oral lesions as these have an important effect on the patient´s quality of life.

Resolución de úlcera sublingual en paciente con parálisis cerebral: informe de un caso / Resolution of sublingual ulcer in cerebral palsy patient: case report

Male patient, 19 years old, diagnosed with severe mixed tetraparesis, predominantly spastic, secondary to severe perinatal asphyxia, West syndrome and intellectual disability, GMFCS V. october 2012 presents a 1 cm white-colored and painless ulcer on the ventral surface of the tongue, showing indurated borders, and no signs of palpable lymph nodes, compatible with Riga-Fede disease. the patient is referred to the commune hospital. August 2013 attends a dental control presenting the ulcer with similar conditions, awaiting treatment from the hospital. April 2014 he returns for a health control in the same conditions. this time a non invasive intervention is performed, covering the incisal edges of teeth 3.1 and 4.1 with composite resin. A two weeks later control shows a smaller ulceration. By June 2015 the ulcer has healed completely, and stayed healed until january 2016. the mother reports decreased tongue protrusion in frequency and intensity since January 2015. Conclusion: Sublingual traumatic ulcer can be healed by eliminating the cause of the trauma, using a non invasive technique.

En octubre de 2012 presenta úlcera en cara ventral de la lengua, de 1 cm de diámetro aproximadamente, de bordes indurados, fondo de color blanquecino e indolora, sin ganglios palpables, compatible con diagnóstico de enfermedad de Riga Fede. Se deriva en esa oportunidad al hospital de su comuna. En agosto de 2013 asiste nuevamente a control presentando la úlcera con similares condiciones, en espera de tratamiento en el hospital. En abril de 2014 vuelve a control en iguales condiciones. En esta oportunidad se realiza intervención no invasiva, recubriendo superficies incisales de dientes 3,1 y 4,1 con resina compuesta. En control a las dos semanas se observa la úlcera más pequeña. En junio de 2014 se observa ausencia de úlcera, situación que persiste hasta control de enero de 2016. La madre manifiesta que protrusión lingual ha disminuido en frecuencia e intensidad desde enero de 2015. Conclusión: La úlcera sublingual de origen traumático puede ser resuelta eliminando la causa del trauma, de forma no invasiva.

Recién nacido con úlcera de Bednar / Bednar's aphthae in newborn

La descripción de la ulcera de Bednar es escasa en la literatura actual. Se ha relacionado con el efecto traumático de la tetina del biberón y/o chupetes no ortodóncicos durante la lactancia. Presentamos a un recién nacido de 20 días de vida que acudió a Urgencias por irritabilidad y se asoció, como único hallazgo al momento de la exploración física, dos úlceras bucales. Describimos la presentación clínica, la evolución y el tratamiento. La normalidad de las pruebas complementarias, las características clínicas y la evolución condujeron al diagnóstico de úlcera de Bednar.

The description of the Bednar's ulcer is uncommon in the current literature. It has been associated with the traumatic effect of the bottle's nipple and/or no orthodontic soothers while breastfeeding. We present a newborn of 20 days of life attended at the emergency room for irritability, with the only finding on physical examination of two oral ulcers. We describe the clinical presentation, evolution and treatment. The normality of the diagnostic test, clinical characteristics and evolution lead to the diagnosis of Bednar's ulcer.

Síndrome de Behcet / Síndrome de Behcet

El síndrome de Behcet, también conocido como enfermedad de Behcet es un proceso autoinflamatorio crónico de baja frecuencia y etiología desconocida. Es una vasculitis que afecta arterias y venas de todos los calibres, provoca una alteración de la función endotelial y se expresa clínicamente con lesiones orgánicas en varios niveles. Tiene una mayor incidencia en los países localizados en la antigua ruta de la seda (mediterraneo del este, oriente medio y este de Asia). En su fisiopatogenia intervienen factores genéticos, microbianos e inmunológicos. Los síntomas varían de persona a persona y de acuerdo a las regiones geográficas, pero los más comunes son las úlceras orales y genitales, inflamaciones oculares (uveítis, retinitis e iritis), lesiones de piel y artritis. En algunos casos pueden presentarse alteraciones del sistema nervioso central, del tracto digestivo y renal. Como guía para el diagnóstico se emplean los criterios del grupo internacional de estudio de la enfermedad de Behcet. El tratamiento incluye medicamentos de uso tópico y sistémico, entre estos los más empleados son los esteroides, los inhibidores del factor de necrosis tumoral y los inmunosupresores(AU)

Behcet's syndrome, also known as Behcet's disease is a chronic autoinflammatory process of low frequency and unknown etiology. It is a vasculitis affecting arteries and veins of all sizes that causes an alteration of endothelial function and is expressed clinically by organ damage at various levels. It has a higher incidence in countries located in the ancient Silk Road (East Mediterranean, Middle East and East Asia). Its pathogenesis involves genetic, microbial and immunological factors.Symptoms vary from person to person and according to geographical regions, but the most common are oral and genital ulcers, eye inflammation (uveitis, iritis and retinitis), skin lesions and arthritis. In some cases they can present central nervous system, gastrointestinal tract and kidney. As a guide to the diagnosis criteria of International Study Group of Behcet's disease are used. Treatment includes topical and systemic drugs. The most commonly used are steroids, tumor necrosis factor inhibitors and immunosuppressants(AU)

Distribution of traumatic injuries after the installation of complete dentures in adult patients

Aim Describe the location of traumatic lesions of the oral mucosa that develop after the installation of complete dentures, as well as to quantify the number of post-operative controls that are required. A descriptive study was conducted by examining 84 patients who attended the dental center of Universidad de Los Andes, San Bernardo, during the period from July 2012 to July 2013. A sample of 120 edentulous patients was obtained. After the fabrication and installation of the complete dentures, at least 3 post-operative controls were performed and the location of oral lesions was recorded. Documentation of the association between the patient's clinical variables and the appearance of oral lesions during the first 3 controls was performed using a logistic regression. Results For maxillary dentures, 5 post-operative visits were made and 6 controls for mandible dentures. In the upper jaw the anatomical areas of higher incidence of traumatic injuries were: canine fossa (23.9%), average bridle (23.1%), and distobuccal sulcus (20.1%). In the lower jaw, the highest number of lesions were recorded on the anterior lingual flank (16.5%), anterior and posterior lingual flank (13.4%), and distobuccal sulcus (12.8%). A significant association was observed between subjects who reported consumption of cholesterol-lowering medications and the development of traumatic lesions of the oral mucosa (OR: 0.25 and 95% CI: 0.055-0.939). The installation of complete dentures does not determine that the treatment has ended. Post-operative controls are needed to assess areas of erythema and ulceration.

Objetivo Describir la ubicación y frecuencia de las lesiones traumáticas de la mucosa oral que se generan después de la instalación de las prótesis dentales completas, y cuantificar el número de controles postoperatorios necesarios. Se realizó un estudio descriptivo, examinando a 84 pacientes que asistieron al centro dental de la Universidad de Los Andes, durante el período comprendido entre de julio de 2012 y julio del de 2013. Se obtuvo una muestra de 120 pacientes edéntulos. Después de la fabricación e instalación de las dentaduras completas se realizaron por lo menos 3 controles postoperatorios y la localización de las lesiones orales fue registrada. La documentación de la asociación entre las variables clínicas de los pacientes y la aparición de lesiones orales durante los 3 primeros controles fue realizado por medio de una regresión logística. Resultados Para prótesis maxilar 5 visitas de controles postoperatorios fueron realizados y 6 para mandibulares. En el maxilar superior las zonas de mayor incidencia de lesiones traumáticas fueron: fosa canina (23,9%), flanco medio (23,1%) y distovestibular del surco (20,1%). En la mandíbula se registraron mayor frecuencia de las lesiones en el flanco lingual anterior (16,5%), anterior y posterior (13,4%) y distovestibular del surco (12,8%). Una asociación significativa se observó entre los sujetos que reportaron consumo de medicamentos reductores del colesterol y el desarrollo de las lesiones traumáticas de la mucosa oral (o: 0,25 e IC: 0,055-0,939). La instalación de las prótesis dentales completas no determina que el tratamiento haya terminado. Los controles postoperatorios son necesarios para evaluar las áreas de eritema y ulceración.

Cutaneous manifestations of systemic lupus erythematosus - an experience from Bahawal-Victoria Hospital, Bahawalpur

To document the frequency of cutaneous manifestation of systemic lupus erythematosus [SLE]. It was a case-series collected from Dermatology Department and all four Medical Units of Bahawal-Victoria Teaching Hospital of Quaid-e-Azam Medical, Bahawalpur. A total of 100 patients with diagnosis of SLE and fulfilling the inclusion criteria were included in the study. All the patients were evaluated for the cutaneous manifestations of SLE. All the information was collected in a specially designed proforma and analyzed with the help of SPSS version 10. The mean age of the patients was 25.97 +/- 4.64 years. 92% patients were female and 8% were male. Out of 100 patients, 85% patient presented with cutaneous manifestations. Photosensitivity was seen in 40 [40%] patients, discoid rash in 35 [35%], malar rash in 25 [25%], and oral ulcers in 24 [24%]. SLE is predominantly seen among female patients of young age. Photosensitivity is most common presentation, followed by discoid rash

Are recurrent denture-related sores associated with the risk of oral cancer? A case control study / Ha associacao entre as feridas bucais por protese dentaria e risco de cancer de boca? Estudo caso-controle

Objectives: This study aimed to assess the hypothesis that recurrent denture-related sores association may be associated with the risk of oral cancer. Methods: We conducted a hospital-based case-control study comprising 71 new cases of oral cancer in two hospitals in São Paulo, Brazil, and 240 controls without cancer, recruited from outpatient units of the same hospitals. All cases had histologically confirmed squamous cell carcinoma in anatomic sites of the mouth that may be specifically consi-dered at risk of sores by ill-fitting dentures. Denture-related sores were assessed by the self-report of recurrent oral sores due to the use of ill-fitting complete removable dental prosthesis. Associations were assessed by multivariate logistic regression conditioned on socio-demographic and behavioral characteristics. Results: The association between ill-fitting dentures and oral cancer was statistically significant in the multivariate model: odds ratio 3.98; 95% confidence interval 1.06 - 14.96. The specific assessment of association between tumors in the lower jaw and sores by mandibular dentures confirmed this result: odds ratio 6.39; 95% confidence interval 1.49 - 29.52. Conclusion: The potential contribution of denture-related sores to oral carcinogenesis still fuels controversies. This study reinfor-ces the hypothesis that recurrent denture-related sores may be associated with the risk of oral cancer. Results reported here also suggest that an appropriate application and monitoring of dental prosthesis represent a non-negligible scope for cancer prevention. .

Objetivo: O presente estudo avaliou a associação entre as feridas recorrentes por prótese dentária mal adaptada e o risco de câncer bucal. Metodologia: Foi realizado estudo caso-controle de base hospitalar que incluiu 71 pacientes com câncer bucal atendidos em dois hospitais da cidade de São Paulo, Brasil. O grupo controle foi composto por 240 pacientes sem câncer, atendidos em ambulatórios diversos dos mesmos hospitais. Todos os casos receberam diagnóstico histológico de carcinoma epidermoide em localizações anatômicas da boca sujeitas a feridas pelo uso de prótese mal adaptada. As feridas decorrentes do uso de prótese mal adaptada foram avaliadas por meio do autorrelato dos pacientes. A análise utilizou modelos de regressão logística não condicional multivariada. Resultados: A associação entre feridas por prótese mal-adaptada e câncer de boca mostrou-se estatisticamente significante no modelo multivariado: OR 3.98; IC95% 1.06 - 14.96. A avaliação específica dos tumores da mucosa inferior confirmou esse resultado (OR 6.39; IC95% 1.49 - 29.52). Conclusão: A contribuição do uso de próteses mal-adaptadas para a carcinogênese bucal ainda é controversa. O presente estudo confirma a hipótese de que as feridas recorrentes pelo uso de próteses mal-adaptadas podem estar associadas ao risco de câncer bucal. Os resultados encontrados sugerem que a avaliação profissional regular das próteses dentárias pode ser importante para a prevenção do câncer. .

Exposición espontánea de un torus palatino de la línea media / Spontaneous exposition of a midline palatal torus

Introducción. El torus , o rodete, palatino es una alteración ósea benigna que puede generar molestias en la fonación y en la deglución. Cuando su crecimiento o exposición persistente producen síntomas molestos, debe ser resecado quirúrgicamente. Presentación del caso. Se trata de una paciente de 82 años de edad, que consultó por una lesión ulcerativa de un año de evolución, que producía dolor, halitosis y molestia a la deglución. En el examen físico de la cavidad oral, se observó una prominencia de consistencia dura en la línea media, con perforación y ulceración de la mucosa palatina en su porción lateral posterior izquierda. Se consideraron los diagnósticos de torus palatino, osteoma, granuloma piógeno y neoplasia de tejidos blandos. Se decidió resecarla quirúrgicamente y hacer el estudio histopatológico. La evolución clínica fue satisfactoria, con resolución completa un mes después de la cirugía. En el estudio de histopatología se observó hiperostosis ósea con inflamación crónica de los tejidos blandos e hiperplasia simple de la mucosa, que corresponden a un torus palatino. Discusión. Se reporta un inusual caso de exposición espontánea de un torus palatino que ocupaba casi toda la bóveda palatina, se describe su resección quirúrgica y se informan los hallazgos de histopatología. En la revisión bibliográfica realizada, no se encontró un reporte previo de exposición espontánea de torus palatino.

Introduction: Palatal torus, or torus palatinus, is a benign bone alteration that may cause some discomfort during phonation or swallowing. When its growth or persistent exposition produces unpleasant symptoms, it must be surgically removed. Case presentation: We treated an 82-year-old female patient who consulted for a painful ulcerous lesion she had had for a year and which produced halitosis and discomfort when swallowing. During the oral cavity physical exam we observed a hard protuberance on the midline. It showed a perforation and ulceration of the lateral posterior palatal mucosa on the left side. We considered the following diagnosis: palatal torus, osteoma, pyogenic granuloma, or a soft-tissue neoplasia. We decided to surgically remove it and to perform a histopathological examination. Clinical evolution was satisfactory with complete resolution one month after surgery. The histopathological examination showed hyperostosis along with chronic inflammation of the soft tissues and a simple hyperplasia of the mucosa, which in turn indicated a palatal torus. Discussion: We report an unusual case of spontaneous exposition of a palatal torus which took up almost all of the hard palate area. Its resection is described and we inform the histopathological findings. In the literature review, we did not find a previous report of a spontaneous exposition of a palatal torus.

Disguised ulcer of lip and buccal mucosa – rare clinicalmanifestation as tuberculosis: a case report / Úlcera de mucosa labial e bucal – uma rara manifestação clínica detuberculose: relato de caso clínico

Introduction: Oral tuberculosis is a chronic granulomatous disease caused by Mycobacterium tuberculosis. According to the World Health Organization (WHO), nearly 2 billion people are infected with tuberculosis. Objective: To report a rare case of oral tuberculosis with ulcers at two different sites. Materials and methods: In order to emphasize the need to consider tuberculosis in the differential diagnosis of non-healing ulcers of oral cavity and the role of oral physician in preventing the spread of such lesions, this article presents a case of oral ulcers at two different sites, diagnosed as tuberculosis ulcer. Results: Oral cavity, which is considered to be a mirror of systemic health, rarely manifests tuberculosis. With increasing number of tuberculosis cases and unusual form of the disease in the oral cavity, the cases are likely to be misdiagnosed. Conclusion: An oral clinician should have a thorough knowledge of tuberculosis and its oral manifestations.

Introdução: A tuberculose oral é uma doença granulomatosa crônica causada pelo Mycobacterium tuberculosis. Segundo a Organização Mundial da Saúde (OMS), cerca de 2 bilhões de pessoas estão infectadas com tuberculose. Objetivo: Relatar um caso raro de tuberculose oral com úlceras em dois locais diferentes. Materiais e métodos: Para realçar a necessidade de considerar a tuberculose sob o diagnóstico diferencial das úlceras não curadas da cavidade oral e o papel do dentista na prevenção da propagação de tais lesões, este artigo apresenta um caso de úlceras orais em dois locais diferentes, diagnosticados como úlcera de tuberculose. Resultados: A cavidade oral, considerada como um espelho da saúde sistêmica, raramente manifesta a tuberculose. Com um número cada vez maior de casos de tuberculose e a forma não usual da doença na cavidade oral, os casos são frequentemente diagnosticados erroneamente. Conclusão: O dentista clínico geral deve ter um conhecimento profundo da tuberculose e de suas manifestações orais.

Ulceras dolorosas en la cavidad oral como expresión de leucemia cutis / painful sores in the oral cavity as an expression of leukemia cutis

Objetivo: presentar el caso de una paciente con leucemia cutis en cavidad bucal, con úlceras dolorosas a partir de las cuales se le diagnosticó leucemia mieloide aguda (LMA). Caso clínico: mujer de 30 años de edad con úlceras bucales dolorosas de cinco meses de evolución, acompañadas por fiebre y pérdida de peso. Tras un estudio histopatológico se diagnostica la infiltración de células leucémicas (Leucemia cutis). Conclusión: la leucemia cutis (LC) es la infiltración de células leucémicas en la piel y/o las mucosas. Por lo general surge en un estadio avanzado de una leucemia previamente diagnosticada. Sin embargo, también puede ser un signo de recidiva tumoral, o incluso la primera manifestación de una leucemia hasta ese entonces desconocida. Si bien las manifestaciones clínicas de la LC son proteiformes, la mucosa bucal es una localización frecuente de este tipo de lesiones.
