Angina bolhosa hemorrágica: uma revisão de literatura / Hemorrhagic angina bullosa: a review of the literature

Introdução: A angina bolhosa hemorrágica (ABH) é uma condição rara caracterizada pelo surgimento súbito de bolhas de sangue nas mucosas orais e orofaringe. Objetivo: Este trabalho tem como propósito fornecer uma análise abrangente das características clínicas, etiológicas e histopatológicas da angina bolhosa hemorrágica, além de abordar métodos de diagnóstico e opções de tratamento. Materiais e métodos: Foi realizada uma busca por artigos científicos publicados de 2010 a 2023, nas bases de dados Scientific Electronic Library Online (SciELO), US National Library of Medicine (PubMed) e ScienceDirect. Foram coletados artigos em inglês e português utilizando as palavras-chave "angina bolhosa hemorrágica", "estomatite bolhosa hemorrágica benigna", "hemorrhagic bullous angina" e "benign hemorrhagic bullous stomatitis". Conclusão: A ABH é escassamente documentada na literatura, com muitos dados ausentes ou subnotificados. Embora seja uma condição benigna com rápida evolução espontânea, o procedimento diagnóstico deve ser rigoroso para descartar outras possíveis lesões.

Introduction: Bullous hemorrhagic angina (ABH) is a rare condition characterized by the sudden appearance of blood blisters on the oral mucosa and oropharynx. Objective: This work aims to provide a comprehensive analysis of the clinical, etiological and histopathological characteristics of hemorrhagic bullous angina, in addition to addressing diagnostic methods and treatment options. Materials and methods: A search was carried out for scientific articles published between 2010 and 2023, in the Scientific Electronic Library Online (SciELO), US National Library of Medicine (PubMed) and ScienceDirect databases. Articles were found in English and Portuguese using the keywords "hemorrhagic bullous angina", "benign herrhagic bullous stomatitis", "hemorrhagic bullous angina" and "benign herrhagic bullous stomatitis". Conclusion: ABH is scarcely documented in the literature, with many data missing or underreported. Although it is a benign condition with rapid spontaneous evolution, the diagnostic procedure must be rigorous to rule out other possible lesions.

The effect of biopolymer gel derived from sugarcane on healing of traumatic oral ulcers: an experimental study

Purpose: The extracellular polysaccharide (EPS) is produced by the bacterium Zoogloea sp. and plays a positive role in tissue repair. The purpose of this study was to clinically and histologically compare the effects of EPS in the healing of traumatic oral ulcers in rats with the effects of triamcinolone. Methods: Ulcers were induced in the oral mucous of 45 male Wistar rats, divided into three groups: control group, treated with triamcinolone, and treated with biopolymer gel. In the clinical evaluation, we considered the weight variation of the animals and the size of the lesion area, at baseline and on treatment days 1, 3 and 7. The histological parameters evaluated were the type and intensity of the inflammatory infiltration, the presence of necrosis and foreign body granuloma and the degree of re-epithelialization of the lesion. Results: The reduction of the lesion area was greater in the animals treated with EPS, with no difference in the intensity of the inflammatory infiltration between the groups on days 3 and 7 of treatment. Conclusions: The results suggest that topical application of EPS in traumatic oral ulcers of rats promotes faster repair than triamcinolone ointment, without increasing the intensity of inflammatory infiltration under the lesion.

Plant extracts used in Brazil for treatment of oral ulcers and mucositis: systematic review / Extratos vegetais utilizados no Brasil para tratamento de úlceras orais e mucosite: revisão sistemática

Objective: To identify and analyze plant extracts used in Brazil for the treatment of oral ulcers and oral mucositis. Material and Methods: A systematic review was registered in PROSPERO (CRD 42018102184) and performed following the PRISMA protocol. The databases searched were PubMed, Web of Science, Scopus, Lilacs, Scielo, the Brazilian Dentistry Library. Manual searches were also performed. Results: Initially, 440 studies were found, of which 392 were excluded after reading the titles and abstracts. A total of 29 articles were read in full and 11 studies were excluded, resulting in 18 articles included in the systematic review. Nine plant species were identified in five clinical trials and 13 in vivo studies, with Chamomila recutita being the most used (33.3% of the studies). Chamomila recutita showed more promising results for analgesic, anti-inflammatory, and healing properties. Calotropis procera latex significantly decreased (p<0.05) inflammatory mediators, such as TNF-α and IL-1ß in oral mucositis induced in rats. Eupatorium laevigatum showed anti-inflammatory activity and analgesic action on oral ulcers. Carapa guianensis Aubl. reduced the severity and painful symptoms of oral mucositis and exhibited better results compared to the use of low power laser. Curcuma longa L accelerated re-epithelialization and resolution of inflammatory processes. Spondias mombin reduced oxidative stress and inflammation caused by oral mucositis and helped on healing it. Extracts of Aloe barbadensis Miller or Aloe vera showed anti-inflammatory action but did not help in the healing process of oral ulcers. Copaifera reticulata Ducke oil did not induce improvement in the healing process, nor did it show an anti-inflammatory effect. Malva sylvestrisdid not show an anti-inflammatory action on oral lesions in humans or rats. The assessment of methodological heterogeneity showed the impossibility of performing a meta-analysis. Risk of bias varied from low to high. Conclusion: The plant species most used and with the best results for the treatment of oral ulcerations and oral mucositis was Chamomilla recutita. Spondias mombin L., Curcuma longa L., Carapa guianensis Aubl and Calotropis procera showed good results in the treatment of oral mucositis, while Eupatorium laevigatum was efficient in the treatment of ulcers of traumatic origin. Malva sylvestris, Copaifera reticulata Ducke, and Aloe barbadensis Miller did not exhibit significant results (AU)

Material e Métodos: Uma revisão sistemática foi registrada no PROSPERO (CRD 42018102184) e realizada seguindo o protocolo PRISMA. As bases de dados pesquisadas foram PubMed, Web of Science, Scopus, Lilacs, Scielo, Biblioteca Brasileira de Odontologia. Buscas manuais também foram realizadas. Resultados: Inicialmente, foram encontrados 440 estudos, dos quais 392 foram excluídos após a leitura dos títulos e resumos. Um total de 29 artigos oram lidos na íntegra e 11 estudos foram excluídos, resultando em 18 artigos incluídos na revisão sistemática. Nove espécies vegetais foram identificadas em cinco ensaios clínicos e 13 estudos in vivo, sendo a Chamomila recutita a mais utilizada (33,3% dos estudos). A Chamomila recutita apresentou resultados mais promissores quanto às propriedades analgésicas, anti-inflamatórias e cicatrizantes. O látex de Calotropis procera diminuiu significativamente (p<0,05) os mediadores inflamatórios, como TNF-α e IL-1ß, na mucosite oral induzida em ratos. Eupatorium laevigatumapresentou atividade anti-inflamatória e ação analgésica em úlceras orais. Carapa guianensis Aubl. reduziu a gravidade e os sintomas dolorosos da mucosite oral e apresentou melhores resultados em comparação com o uso do laser de baixa potência. Curcuma longa L. acelerou a reepitelização e resolução de processos inflamatórios. Spondias mombinreduziu o estresse oxidativo e a inflamação causadas pela mucosite oral e ajudou na sua cicatrização. Extratos de Aloe barbadensis Miller ou Aloe vera apresentaram ação anti-inflamatória, mas não auxiliaram no processo de cicatrização de úlceras orais. O óleo de Copaifera reticulata Ducke não induziu melhora no processo cicatricial, nem apresentou efeito anti-inflamatório. Malva sylvestris não apresentou ação anti-inflamatória em lesões orais em humanos ou ratos. A avaliação da heterogeneidade metodológica mostrou a impossibilidade de realizar uma meta-análise. O risco de viés variou de baixo a alto. Conclusão: A espécie vegetal mais utilizada e com melhores resultados para o tratamento de ulcerações orais e mucosite oral foi a Chamomilla recutita. Spondias mombin L., Curcuma longa L., Carapa guianensis Aubl e Calotropis procera apresentaram bons resultados no tratamento da mucosite oral, enquanto Eupatorium laevigatum foi eficiente no tratamento de úlceras de origem traumática. Malva sylvestris, Copaifera reticulata Duckee Aloe barbadensis Miller não apresentaram resultados significativos(AU)

Carcinoma oral de células escamosas en el paladar: reporte de un caso / Oral squamous cell carcinoma of the palate: a case report

El cáncer oral representa un grave problema de salud a nivel mundial debido a su importante morbilidad y mortalidad. Ocupa la sexta causa de muerte por cáncer y tienen una supervivencia mundial a cinco años cercana a 50%, en gran parte debido a la falta de su reconocimiento en estadios iniciales por parte de los pacientes y de los mismos profesionales de la salud, lo que ocasiona un grave retraso en su diagnóstico y tratamiento. Se presenta el caso de una mujer de 64 años de edad con úlceras de larga evolución en la cavidad oral y quien acude a múltiples profesionales de salud sin ser diagnosticada en las fases iniciales de la enfermedad; acude a la Universidad Autónoma de Tlaxcala en donde se diagnostica carcinoma oral de células escamosas en el maxilar. En el presente artículo se hace énfasis en el reconocimiento de signos clínicos y factores precipitantes que puedan generar sospecha de un crecimiento maligno y así concientizar a los profesionales de la salud para promover la prevención (AU)

Oral cancer represents a serious health problem worldwide due to its significant morbidity and mortality, it is the sixth leading cause of cancer death and has a global 5-year survival rate of 50%, largely due to the lack of recognition in early stages by patients and health professionals themselves, which causes a serious delay in diagnosis and treatment. We present the case of a 64-year-old woman with long-standing ulcers in the oral cavity who went to multiple health professionals without being diagnosed in the initial stages of the disease. She went to the Autonomous University of Tlaxcala where oral squamous cell carcinoma (OSCC) in the maxilla was diagnosed. This article emphasizes the recognition of clinical signs and precipitating factors that may generate suspicion of malignant growth and thus raise awareness among health professionals to promote prevention (AU)

Aplicação da fotobiomodulação laser em úlceras traumáticas na cavidade oral: revisão integrativa da literatura / Laser photobiomodulation application in traumatic ulcers in the oral cavity: integrative literature review

As úlceras traumáticas representam uma condição benigna e recorrente que acomete a cavidade oral, com variação de tamanho e dimensão. Existem inúmeras terapias que podem ser empregadas com o objetivo de promover analgesia e(ou) reparo tecidual. A fotobiomodulação laser (FBML) tem adquirido espaço no manejo dessas lesões, por se tratar de um dispositivo minimamente invasivo e bem tolerado pelo organismo, além de atuar na bioestimulação, o que confere efeito analgésico, anti-inflamatório e cicatricial. Dessa maneira, o estudo tem como objetivo avaliar a aplicação terapêutica da FBML em úlceras traumáticas na cavidade oral. Tratou-se de uma revisão integrativa da literatura, com base na pesquisa de artigos científicos dos últimos nove anos, realizada nas plataformas LILACS, BVS, SciELO, PubMed, e Google Acadêmico, utilizando o cruzamento de Descritores em Ciências da Saúde (DeCS) e empregando o uso dos operador booleano "AND". De forma adicional, a busca livre foi realizada com vistas à complementação da fundamentação teórica. Um total de sete artigos foram incluídos na presente revisão integrativa, o que incluiu estudos em humanos e em modelo animal. Todos os estudos incluídos apresentaram resultados positivos com a utilização da FBML, que demonstrou efeito benéfico através de uma ou duas sessões, com indução do processo de cicatrização, melhora da sintomatologia dolorosa e da inflamação. A FBML foi capaz de melhorar o quadro clínico e histológico das úlceras traumáticas em cavidade oral, através da modulação da percepção da dor e da inflamação, aceleração da cicatrização e consequente regressão das lesões.

Traumatic ulcers represent a benign and recurrent condition that affects the oral cavity, varying in size and dimension. There are numerous therapies that can be used to promote analgesia and/or tissue repair. Laser photobiomodulation (FBML) has gained space in the management of these lesions, as it is a minimally invasive device that is well tolerated by the body, in addition to acting in biostimulation, which confers analgesic, anti-inflammatory and healing effects. Thus, the study aims to evaluate the therapeutic application of FBML in traumatic ulcers in the oral cavity. This was an integrative literature review, based on the research of scientific articles from the last nine years, carried out on the LILACS, BVS, SciELO, PubMed, and Google Scholar platforms, using the intersection of Health Sciences Descriptors (DeCS) and employing the use of the Boolean operator "AND". Additionally, the free search was carried out with a view to complementing the theoretical foundation. A total of seven articles were included in this integrative review, which included studies in humans and in an animal model. All included studies showed positive results with the use of FBML, which demonstrated a beneficial effect through one or two sessions, inducing the healing process, improving pain symptoms and inflammation. FBML was able to improve the clinical and histological picture of traumatic ulcers in the oral cavity, by modulating the perception of pain and inflammation, accelerating healing and consequent regression of the lesions.

Distribution and Drug Resistance of Pathogens in Oral Mucositis Associated with Chemotherapy in Patients with Malignant Hematopathy / 中国实验血液学杂志

OBJECTIVE@#To analyze the distribution and drug resistance of pathogens in oral mucositis associated with chemotherapy in hospitalized patients with malignant hematopathy, so as to provide scientific evidences for rational selection of antibiotics and infection prevention and control.@*METHODS@#From July 2020 to June 2022, 167 patients with malignant hematopathy were treated with chemical drugs in the Department of Hematology, Hainan Hospital, and secretions from oral mucosal infected wounds were collected. VITEK2 COMPECT automatic microbial identification system (BioMerieux, France) and bacterial susceptibility card (BioMerieux) were used for bacterial identification and drug susceptibility tests.@*RESULTS@#A total of 352 strains of pathogens were isolated from 167 patients, among which 220 strains of Gram-positive bacteria, 118 strains of Gram-negative bacteria and 14 strains of fungi, accounted for 62.50%, 33.52% and 3.98%, respectively. The Gram-positive bacteria was mainly Staphylococcus and Streptococcus, while Gram-negative bacteria was mainly Klebsiella and Proteus. The resistance of main Gram-positive bacteria to vancomycin, ciprofloxacin and gentamicin was low, and the resistance to penicillin, cefuroxime, ampicillin, cefotaxime, erythromycin and levofloxacin was high. The main Gram-negative bacteria had low resistance to gentamicin, imipenem and penicillin, but high resistance to levofloxacin, cefotaxime, cefuroxime, ampicillin and vancomycin. The clinical data of oral mucositis patients with oral ulcer (severe) and without oral ulcer (mild) were compared, and it was found that there were statistically significant differences in poor oral hygiene, diabetes, sleep duration less than 8 hours per night between two groups (P<0.05).@*CONCLUSION@#Gram-positive bacteria is the main pathogen of oral mucositis in patients with malignant hematopathy after chemotherapy. It is sensitive to glycopeptide antibiotics and aminoglycosides antibiotics. Poor oral hygiene, diabetes and sleep duration less than 8 hours per night are risk factors for oral mucositis with oral ulcer (severe).

Effects of honey-lemon spray on recurrent aphthous stomatitis comparing to Triamcinolone ointment: a randomized controlled clinical trial

Recurrent aphthous stomatitis (RAS) is recurrent and painful diseases of the oral mucosa that can be very painful and annoying despite their small size. There is no definitive cure for this disease and the usual treatments are mainly based on pain control. The aim of this study was to investigate the effect of honey-lemon spray (mucotin) in the treatment of recurrent aphthous stomatitis. Methods: This study is a randomized controlled clinical trial conducted in 2020 at Zahedan University of Medical Sciences on 46 RAS patients. The participants were randomly assigned to the intervention (mucotin) or control groups (Triamcinolone ointment) equally (23 patients in each group). Patients were evaluated for the severity of pain and ulcer size. Evaluations were performed on days 0, 2, 7 of the treatment using VAS. Data were analyzed using ANOVA statistical test. Results: The inner aspect of the lower lip was the most common site of RAS in the participants (48.8%) and the lowest site went for hard palate (2.4%). Four items including pain, burning sensation, necrosis area, and erythematous area were evaluated in both groups. There was no significant difference in all parameters before the treatment period (day 0). The mean pain score, burning sensation, necrosis, erythematous areas were not different in days 0, 2 and 7 between groups respectively (p=0.849, p=0.105, p=0.917, p=0.442). Conclusion: Honey-lemon spray (Mucotin) and topical corticosteroid have similar effects in RAS treating, So Mucotin can be used as the first line of treatment for RAS lesions. This herbal medicine has no side effects

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.

Directrices para el diagnóstico y tratamiento de Molares Retenidos / Guidelines for diagnosis and treatment of impacted molars

Los terceros molares son piezas dentarias correspondientes a la dentición permanente y se encuentran por detrás de los segundos molares. Erupcionan entre los 18 y 27 años aproximadamente, tienen variedad de formas, anomalías y disposición diversa. Normalmente se encuentran total o parcialmente retenidos en el hueso maxilar. La retención es muy frecuente y afecta aproximadamente al 75% de la población. La causa principal es por la falta de espacio dentro de la boca. La patología derivada de la retención de un tercer molar puede generar diferentes alteraciones: abscesos, sinusitis, reabsorción de las raíces de los dientes adyacentes, caries del molar retenido y/o del segundo molar, úlceras en la mucosa contigua, podrían generar quistes, ameloblastomas y ulceraciones leucoqueratósicas que pueden degenerar en carcinomas, alteraciones nerviosas o vasomotoras: dolores faciales, trismus, y parálisis facial ipsilateral. Las extracciones profilácticas de terceros molares asintomáticos están justificadas cuando los terceros molares se encuentran bajo prótesis removible que puede estimular su erupción, molares semierupcionados que pueden generar pericoronitis, caries o problemas periodontales; pacientes que van a ser sometidos a radioterapia; cuando el diente incluido interfiera en una cirugía ortognática. Si el molar retenido presenta sintomatología por parte del paciente está aconsejada su extracción quirúrgica.

The third molars are dental pieces corresponding to the permanent dentition and are located behind the second molars. They erupt between the ages of 18 and 27 approximately, have a variety of shapes, anomalies, and diverse dispositions. They are normally fully or partially retained in the maxillary bone. Retention is very frequent and affects approximately 75% of the population. The main cause is due to the lack of space inside the mouth. The pathology derived from the retention of a third molar can generate different alterations: abscesses, sinusitis, resorption of the roots of adjacent teeth, caries of the retained molar and/or second molar, ulcers in the contiguous mucosa, could generate cysts, ameloblastomas and leukokeratotic ulcerations that can degenerate into carcinomas, nervous or vasomotor disorders: facial pain, trismus, and ipsilateral facial paralysis. Prophylactic extractions of asymptomatic third molars are justified when the third molars are under removable prosthesis that can stimulate their eruption, semi-erupted molars that can generate pericoronitis, caries or periodontal problems; patients who are going to undergo radiotherapy; when the included tooth interferes with orthognathic surgery. If the retained molar presents symptoms on the part of the patient, its surgical extraction is recommended.

Manifestaciones orales de la viruela símica y recomendaciones para su prevención en la práctica odontológica / Oral manifestations of monkeypox and recommendations for its prevention in dental practice

El brote reciente de viruela símica ha despertado el interés de la comunidad internacional por su creciente número de contagiados en países no endémicos. Entre sus síntomas se encuentran la fiebre, dolor de cabeza, fatiga, dolor muscular, exantema y linfadenoma. La cavidad bucal es el lugar en el que suelen aparecer los primeros signos de la enfermedad. Por tanto, el objetivo de este trabajo fue establecer las principales manifestaciones orales de la viruela del mono y enumerar algunas recomendaciones de prevención. Para ello, se hizo una revisión bibliográfica entre 2012 y 2022 en la base de datos PubMed, usando las palabras clave, en inglés, monkeypox, oral manifestation y transmission. Se garantizó que, de los 14 documentos seleccionados, al menos el 80%, fueran publicaron en 2022. Las manifestaciones orales más frecuentes fueron: úlcera eritematosa, vesículas-ulcerosas y las asociadas a linfadenopatía (disfagia, odinofagia y faringitis). Entre las recomendaciones se encuentran: uso de mascarilla N95 y visores faciales, lavado constante de manos y espacios y atención de contagiados solo por eventos agudos (urgencias). Aunque no se ha confirmado, es posible que el Tecovirimat sea de ayuda en pacientes con sintomatología grave. Se concluye que es necesario que los odontólogos sepan distinguir los signos orales de la enfermedad para que contribuyan a cortar la cadena de contagio y deriven prontamente a los sospechosos para que se hagan las pruebas diagnósticas y las terapias medicamentosas de manera oportuna(AU)

The recent outbreak of monkeypox has aroused the interest of the international community due to its growing number of infections in non-endemic countries. Its symptoms include fever, headache, fatigue, muscle pain, rash, and lymphadenoma. The oral cavity is the place where the first signs of the disease usually appear. Therefore, the objective of this work was to establish the main oral manifestations of monkeypox and list some prevention recommendations. For this, a bibliographic review was carried out between 2012 and 2022 in the PubMed database, using the keywords, in English, monkeypox, oral manifestation and transmission. It was guaranteed that, of the 14 selected documents, at least 80% would be published in 2022. The most frequent oral manifestations were: erythematous ulcer, ulcer-vesicles and those associated with lymphadenopathy (dysphagia, odynophagia and pharyngitis). Among the recommendations are: use of N95 mask and face visors, constant washing of hands and spaces, and attention to those infected only due to acute events (emergencies). Although it has not been confirmed, it is possible that Tecovirimat is helpful in patients with severe symptoms. It is concluded that it is necessary for dentists to know how to distinguish the oral signs of the disease so that they contribute to breaking the chain of contagion and promptly refer suspects to diagnostic tests and drug therapies in a timely manner(AU)

Effect of Dentoxol® in the treatment of recurrent mild aphthous ulcers. A prospective observational pilot study

ABSTRACT: Background: Recurrent aphthous stomatitis (RAS) is the most common oral ulceration. Its prevalence in the general population varies between 5% and 60%, and during the acute period, it causes pain and interferes with basic activities, such as eating, swallowing and talking. Dentoxol® is a medical mouthrinse that cleans, moisturizes and lubricates the mouth, mechanically stimulating local epithelial regeneration. The aim of this study was to evaluate the efficacy of Dentoxol® in improving the general state of patient with minor RAS using two different treatment schemes. Material and methods: Thirty-nine patients with RAS were recruited in a prospective observational pilot study. Two dosing regimens, 5 ml of Dentoxol® twice daily and 5 ml of Dentoxol® three times daily were evaluated. Results: Efficacy to improve the general state was significant superior in "Three time daily" group compared with "twice daily" at 72 h (66% vs 33% respectively). No pain was reported in approximately 90% of cases at 96 h of use in both group without significant differences between the groups in any evaluation time-point. Conclusion: Despite the limitations of these preliminary data, Dentoxol® shows promising beneficial properties for the management of minor RAS.

Difficult and complicated oral ulceration: an expert consensus guideline for diagnosis / 国际口腔科学杂志·英文版

The complexity of oral ulcerations poses considerable diagnostic and therapeutic challenges to oral specialists. The expert consensus was conducted to summarize the diagnostic work-up for difficult and complicated oral ulcers, based on factors such as detailed clinical medical history inquiry, histopathological examination, and ulceration-related systemic diseases screening. Not only it can provide a standardized procedure of oral ulceration, but also it can improve the diagnostic efficiency, in order to avoid misdiagnosis and missed diagnosis.

Facial Palsy with Tongue Ulcer: A Rare Initial Presentation of Granulomatosis with Polyangiitis

ABSTRACT@#Granulomatosis with polyangiitis (GPA) is a rare multisystem disease. Although GPA is rare, it commonly presents in a localised stage where its manifestation involves the upper or lower respiratory tract before progressing to a generalised stage. Therefore, most patients with GPA will visit an oral surgeon or an otolaryngologist to seek treatment. However, the diagnosis of GPA is often delayed as GPA is not frequently considered as a differential diagnosis in common oral and facial diseases. The lack of gold standard investigation for the diagnosis of GPA makes management of this case, a diagnostic conundrum. We herein report a patient who was diagnosed with bilateral acute otitis media and left mastoiditis complicated with facial nerve palsy, and later developed tongue ulceration one month after his initial presentation. The ear, facial and oral symptoms represent a diagnostic red herring to a full-blown generalised stage of GPA.

Aplicação do laser de baixa intensidade no tratamento do eritema multiforme: relato de caso / Low intensity laser application in the treatment of erythema multiforme: case report

Objetivo: Este trabalho tem como objetivo relatar um caso de Eritema Multiforme (EM) menor desencadeado por amoxicilina oral, tratado a partir de aplicação de laser de baixa intensidade na região afetada pela doença. Relato de caso: Paciente de 12 anos, atendido no Hospital Metropolitano Odilon Behrens (HMOB), apresentando úlceras em mucosa jugal, lábios e língua, disfagia, dislalia e febre, recebeu diagnóstico clínico de EM e tratamento com aplicação de laser vermelho de baixa intensidade, emitindo em 660nm, com potência de 100mW, sendo aplicado uma dose de 33 J/cm², em pontos com distância aproximada de 1 cm entre eles. Houve resolução das lesões em 7 dias após instituição do tratamento. Conclusão: O presente trabalho mostrou que a Terapia de Fotobiomodulação (TF) com laser de baixa intensidade associado à substituição do medicamento detectado como causa foram fundamentais para a resolução do EM, evidenciando as propriedades bioestimulantes do laser nas lesões ulceradas de mucosa bucal.

Aim: This paper aims to report a case of minor Erythema Multiforme (EM) triggered by oral amoxicillin, treated with low-level laser applications in the region affected by the disease. Case report: A 12-year-old patient, treated at the Metropolitan Hospital Odilon Behrens, presenting ulcers in the buccal mucosa, lips, tongue, dysphagia, dyslalia, and fever, received a clinical diagnosis of EM and treatment with low-intensity red laser applications, emitted at 660 nm, with a power of 100 mW, with a dose of 33 J/cm² being applied, in points with an approximate distance of 1 cm between them. The lesions resolved within 7 days after treatment were instituted. Conclusion: This present paper shows a successful therapeutic, non-pharmacological alternative for the management of EM, showing the bio stimulating properties of laser in ulcerated lesions of the oral mucosa.

Oral ulcers and sarcoid-like reaction in lymph nodes after cemiplimab therapy for locally advanced cutaneous squamous cell carcinoma: a case report

ABSTRACT Cemiplimab is a novel programmed death-1 inhibitor recently approved for advanced cutaneous squamous cell carcinoma. Immune-related adverse events derived from cemiplimab are similar to other anti-PD-1 drugs, including gastrointestinal and cutaneous toxicities. Oral immune-related adverse events were not reported with cemiplimab in previous studies; thus this case report warns of the fact that the oral cavity may be a site of immune-related adverse events during programmed death-1 block therapy and that this can lead to significant limitations when not properly treated. The present report describes the case of a patient with locally advanced cutaneous squamous cell carcinoma metastatic to cervical lymph nodes who developed dysphagia due to large and painful oral ulcers after a single dose of cemiplimab. The patient also exhibited a sarcoid-like reaction in mediastinal lymph nodes. No immune-related adverse events were found in any other organs. The oral lesions showed significant improvement after topical and short-course systemic corticosteroids, and low-level laser therapy was also performed in the oral lesions. The patient achieved a near-complete response and treatment was discontinued. This article discusses in detail the clinical outcomes and oral toxicity management of cemiplimab therapy for cutaneous squamous cell carcinoma.

Oral Alterations in a COVID-19 Patient: case Report and Update of Main Findings / Alteraciones Orales en un Paciente con COVID-19: reporte de un Caso y Actualización de los Principales Hallazgos

COVID-19 was characterized as a pandemic due to the worldwide dissemination and the severity with which the disease attacks the human organism. Some oral lesions have been observed in COVID-19 patients. However, there is still no concrete evidence of the real influence of SARS-CoV-2 on the human body, especially in the oral region. In this context, the present report discusses a case of a COVID-19 patient with oral alterations. The male patient presented ulcerative lesions of painful symptomatology and petechiae in the oral mucosa. This study also performed a literature review of the main oral alterations reported in the literature. Although more studies with a larger number of cases should be performe d, the present clinical case may have manifested signs of this pathology in the oral cavity since the epithelial cells of the oral mucosa have ACE2 receptors.

El COVID-19 se caracterizó como una pandemia debido a la diseminación mundial y la gravedad con la que la enfermedad ataca al organismo humano. Se han observado algunas lesiones orales en pacientes con COVID-19. Sin embargo, todavía no hay evidencia concreta de la influencia del SARS-CoV-2 en el cuerpo humano, especialmente en la cavidad oral. En este contexto, el presente reporte analiza un caso de un paciente con COVID-19 con alteraciones orales. El paciente de sexo masculino presentó lesiones ulcerativas de sintomatología dolorosa y petequias en la mucosa oral. Este estudio también realizó una revisión de la literatura de las principales alteraciones orales reportadas en la literatura. Si bien se deben realizar más estudios con un mayor número de pacientes, el presente reporte de caso puede haber manifestado signos de esta patología en la cavidad oral ya que las células epiteliales de la mucosa oral tienen receptores ACE2.
