Granuloma gravidarum (GG) is an inflammatory lesion, which develops in the oral mucosa of pregnant women in response to chronic low-grade irritants, under the influence of hormonal factors.Objective:To characterize GG clinically by means of a retrospective study of the cases of the Oral Medicine Division, São Lucas Hospital, Brazil.Material and Methods:Cases of GG diagnosed between 1980 and 2012 were analyzed. Data were obtained referring to the age of the patients, lesion location, clinical features, as well as the presence of local irritants. The gestation period in which the lesion developed was also investigated. Results:Forty-one cases of GG were found. The lesions developed predominantly in the third trimester of pregnancy (51.22%) and the mean age of the patients was 28 years. Most GG was found in the gingiva (73.17%), was reddish color and had a mean diameter of 1.5 cm. Local irritants were involved in 75.6% of the cases.Conclusions:The hormonal conditions of pregnancy can have an impact on the oral cavity, predisposing the patient to inflammatory lesions such as GG.

The evaluation of pre-clinical technical achievement in fixed prosthodontics cannot be objective when using visual examination of dental preparations. This is, however, still the main method used in dental schools. The present study introduces a new method, based on a mathematical formula, to reduce the problem. The idea emerged when using the Kavo PrepAssistant system (software version 1.05). This system is a 3D-scanner with software that can quantify geometrical differences between an instructor and student dental preparation in model teeth. Therefore, a mathematical formula was created, integrating selected clinically relevant geometric characteristics of dental preparations measured by the system. In this new formula, 70% of the evaluation parameters were computer analysed, whilst 30% were visually evaluated. This new method was compared with the traditional visual evaluation system during a pre-clinical practical examination, with the participation of 25 students. Using both methods to evaluate the 25 preparations, results showed similar grading for both methods (K-S test = 0.16; P < 0.05). Although this method does not provide overall clinical evaluation of student performance these results suggest that it can be helpful accessing technical achievement. In this method, the student has the guarantee that 70% of his/her grade results from an objective computer evaluation, with the possibility to visualise the mistakes with the software. It also reduces problems related to the calibration between different examiners. The Kavo PrepAssistant is a powerful tool in pre-clinical teaching, but has some drawbacks. It has to be developed towards the actual needs of pre-clinical departments, in order to achieve its full potential, as described in this study.

A new disease called coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus-2 (SARS-COV-2) virus, was discovered in the city of Wuhan in China in December 2019, and has reached, quickly and progressively, several countries on different continents. Even before the World Health Organization recognized the COVID-19 epidemic as a pandemic, the Brazilian Ministry of Health had already declared COVID-19 a national public health emergency due to the confirmation of cases in Brazil. In this scenario, the educational sector was one of the first to suffer the effects of the pandemic soon after the announcement of social distancing as a way to prevent the collapse of the Unified Health System. The aim of this paper is to report how Brazilians dental schools are leading with the new coronavirus pandemic.

Objective. The aim of this study was to evaluate stress, anxiety, and salivary alpha-amylase (SAA) activity in patients with recurrent aphthous stomatitis (RAS). The impact of this disease on the life quality was also evaluated. Design. Twenty-two patients with RAS and controls, matched by sex and age, were selected. Stress and anxiety were assessed using Lipp's Inventory of Stress Symptoms and Beck Anxiety Inventory. Life quality was assessed through the World Health Organization Quality of Life-bref (WHOQOL-BREF) and the Oral Health Impact Profile-14 (OHIP-14). Saliva samples were collected in the morning and afternoon and the SAA activity was analyzed by enzymatic kinetic method. Results. No significant difference was observed between the groups regarding the SAA activity (p = 0.306). Patients with RAS had higher scores of anxiety (p = 0.016). The scores of WHOQOL-BREF were significantly lower in patients with RAS. The values obtained through OHIP-14 were significantly higher in these patients (p = 0.002). Conclusion. RAS negatively affects the life quality. Patients with the disease have higher levels of anxiety, suggesting its association with the etiopathogenesis of RAS.

Objetivo: Relatar um caso clínico de lesões cutâneas e intraorais na paracoccidioidomicose generalizada. Descrição do caso: Paciente do sexo masculino, 44 anos, apresentando perda de peso havia 4 meses, tosse e febre frequente, com hipótese diagnóstica de tuberculose, procurou atendimento odontológico por conta de lesão bucal ulcerada assintomática de aspecto granulomatoso. O paciente apresentava marcha lenta, sinais de debilidade orgânica e fraqueza, além de uma lesão descamativa em sobrancelha esquerda. Após avaliação de exames de imagem, sorológicos e hematológicos, optou-se pela realização da biópsia incisional da lesão a nível ambulatorial. O laudo histopatológico das colorações em H/E e a Histoquímica em Grocott tiveram diagnóstico conclusivo para paracoccidioidomicose. Devido à debilidade do paciente, o mesmo foi encaminhado para tratamento a nível hospitalar no Departamento de Medicina Tropical do Hospital Professor Edgar Santos da Universidade Federal da Bahia. Atualmente encontra-se sem lesões, porém ainda continua em tratamento. Conclusão: A paracoccidioidomicose é uma micose sistêmica grave, que representa um sério problema em países da America Latina, principalmente o Brasil. É necessário que os profissionais estejam atentos as características clínicas da doença para um correto diagnóstico e encaminhamento para instituição do tratamento adequado. A participação do Cirurgião-Dentista e do Estomatologista é de suma importância para estabelecimento do diagnóstico diferencial desta lesão e encaminhamento para o centro médico especializado, sempre mantendo contato com os profissionais envolvidos no tratamento.

Pycnodysostosis is a rare genetic disease that is characterized by osteosclerosis, short stature, and bone fragility. There are not cases of gnathic bones lesions reported on the international literature. This study aims to describe a clinical case of a 10-year-old girl with pycnodysostosis syndrome and an uncommon association with 4 distinct lesions (dentigerous cyst, central giant cell lesions, and 2 fibro-osseous lesions).

IntroduçãoO termo "miíase" é derivado do grego myio (mosca) e ase (doença) e é usado para definir a invasão dos tecidos vivos humanos e de outros mamíferos por ovos ou larvas de moscas da ordem díptera, sendo mais frequentemente observada em países tropicais 1 . As larvas de Cochliomyia hominivorax e Dermatobia são os agentes causais mais comuns das miíases humanas na América. A ocorrência de miíase bucal é rara e há poucos relatos de casos clínicos na literatura descrevendo essa condição 2,3 .As miíases são classificadas de acordo com os aspectos biológicos e evolutivos. Dividem-se em dois grandes grupos: biontófagas e necrobiontófogas. As biontófagas ou parasitárias, são caracterizadas como invasores primários, tem a capacidade de invadir tecidos sadios e feridas recentes. Já, as necrobiontógafas ou facultativas, nutrem-se de tecidos orgânicos em decomposição ou podem atingir eventualmente tecidos necrosados em um hospedeiro vivo 1,4 .As manifestações clínicas não são específicas e variam de acordo com a região acometida 5 . A ocorrência de miíase em cavidade bucal é rara e, nesses casos, a localização mais frequente é a região anterior de maxila. O aspecto pode variar de pequenas Objetivo: este trabalho tem como objetivo relatar um caso clínico de miíase, acometendo cavidade bucal de paciente portadora de síndrome de Wilson e discutir as principais medidas para a prevenção e o tratamento da miíase. Relato de caso: paciente do gênero feminino, 30 anos de idade, portadora da doença de Wilson, dependente para as atividades da vida diária, apresentando ausência de selamento labial e cuidado de higiene oral inadequado. O diagnóstico de miíase foi estabelecido clinicamente quando observou-se sangramento na boca, presença de larvas e ausência da mucosa do palato. Foi solicitada a internação no centro cirúrgico para debridamento do tecido e remoção das larvas. Durante procedimento ficou constatado presença de colônia de larvas também no interior da língua. Considerações finais: a ocorrência de miíase em cavidade bucal é rara. Alguns fatores são predisponentes, dentre esses: a senilidade, as doenças e debilidades neurológicas, a halitose. O principal tratamento constitui-se de remoção mecânica e prescrição medicamentosa antibacteriana e antiparasitária. A paciente do caso em análise foi tratada em centro cirúrgico, com remoção mecânica das larvas, e os responsáveis por ela foram orientados para uma higiene oral adequada para evitar a reinfestação.Palavras-chave: Miíase. Cavidade oral. Língua. Palato. Doença de Wilson.
