Lemierre's syndrome is characterized by thrombophlebitis in the internal jugular vein after an infection in the area of the head or neck, mostly in the form of pharyngitis and/or tonsillitis. It may also result from less common conditions, such as odontogenic infections, but this condition has not often been reported in the dental literature. The syndrome's main etiological agent is Fusobacterium necrophorum, and it most commonly occurs in young adults. This study reports the clinical case of a 34-year-old female patient of poor socioeconomic status with a history of pericoronitis, who reported having a chest pain that radiated to the upper limbs, along with dyspnea. The computed tomography of her neck provided evidence of an acute thrombus in the right internal jugular vein. The treatment comprised antibiotic and anticoagulant therapy in addition to the extraction of her third molar and some residual roots. This report highlights the perils of systemic complications through dental infection, including the risk of death.

Objective To verify the prevalence of dental anomalies in terms of number, position and shape, and the presence of bone alterations, through analysis of panoramic radiographs. Methods This study evaluated dental anomalies and bone alterations in children aged 6 to 12 years-old, detected on panoramic radiographies recorded in the radiographic database of the Federal University of Espírito Santo between 2012 and 2016. Clinical and demographic information were registered. Dental records were retrieved to obtain the medical history involving syndromes or other diseases that may interfere with the anomalies and alterations. Chi-square and exact Fischer’s statistical tests were performed. Results There were alterations in 83 out of 301 panoramic radiographs analyzed. There were 169 anomalies or alterations (mean of 2,04±1,38 anomalies/patient), involving 201 teeth. The most prevalent anomaly was tooth impaction (26.63%), which affected the canines more frequently, followed by hypodontia (24.26%), more often found in the second premolar, and both affected mostly females. Hyperdontia and radiolucent lesions showed the same prevalence (18.93%), the most affected teeth were those of the anterosuperior region and the first mandibular molars, respectively. The least prevalent anomalies were dilaceration (7.69%), taurodontism (2.37%) and radiopaque lesions (1.18%). Bone alterations were significantly more found in mandible and in the posterior region, which confirms the prevalence in the lower molars. Conclusion Although there was no statistically significant difference regarding sex, there was a high prevalence of anomalies and alterations in our study population, which indicates the importance of its diagnosis by means of a panoramic x-ray examination.

Violence against children does not occur only in developing countries and happens so frequently that it is sometimes trivialized. Children and adolescents are easy targets for acts of violence because they are frail and dependent. The aim of this study was to verify the knowledge of dental students, by means of questionnaires, regarding maltreatment in childhood and adolescence. Application of a questionnaire to dental students enrolled in the Dentistry course of the University of Planalto Catarinense and Federal University of Espirito Santo, with an approach to the concept and characteristics of maltreatment, conduct when faced with this, knowledge about the Child and Adolescent Statute (CAS), and the dentist's responsibility about notification of maltreatment. The data were analyzed by means of descriptive statistics in absolute frequencies and percentages. In the research, 363 students participated. Of these 265 (73%) were of the female gender, and the mean age was 21.38 years (± 3.01). During the undergraduate period, 34,9% of the students affirmed they had not received any information about maltreatment in childhood and adolescence, and despite this, the majority (86,8%) felt they were capable of diagnosing cases of maltreatment. The students mentioned alterations in soft tissues (65,3%), dental traumas (48,5%), as characteristics related to maltreatment. Regarding making a complaint/pressing charges, only 30,3% mentioned the Guardian Council and 35,3% knew the meaning of "CAS". It was observed that students from the two Institutions could identify signs of maltreatment, but they needed more information about the notification of these events.

A elaboração do diagnóstico correto e tratamento adequado é um dos maiores desafios que o cirurgião-dentista enfrenta na prática clínica. As radiografias são exames complementares neste processo, fornecendo informações importantes, e a radiografia panorâmica se destaca pela grande área examinada e pequena dose de radiação. O princípio da Justificação na Portaria SVS/MS nº 453/98 afirma que os exames devem apresentar um motivo para exposição do paciente à radiação X. Objetivou-se analisar as prescrições de exames radiográficos por acadêmicos de Odontologia, encaminhadas ao Setor de Radiologia Odontológica da Universidade Federal do Espírito Santo (UFES) quanto às informações fornecidas e à justificação da exposição. Tratou-se de um estudo observacional transversal baseado em dados secundários. Foram utilizadas todas as solicitações de exames recebidos e executados no setor de Radiologia da UFES, no período de janeiro de 2013 a dezembro de 2015. Foram analisadas 1251 solicitações de exames radiográficos sendo que 1174 eram referentes a exames panorâmicos. Constatou-se que a maior parte dos pacientes era do gênero feminino, 48,5% das solicitações não foram datadas, apenas 15,8% possuíam registro da suspeita clínica, sendo que dessas 58,68% traziam como justificativa “para fins de diagnóstico”. Também foi observado que 92,1% estavam assinadas, 91,9% foram carimbadas, 53,2% das solicitações eram manuscritas e a disciplina que mais solicitou foi a Estomatologia. Em conclusão, ficou clara a necessidade de serem reforçados os conteúdos sobre a forma correta de se prescrever um exame complementar no curso de graduação.

Durante a graduação em Odontologia o aluno enfrenta situações que podem causar danos à própria saúde, visto que estão expostos a diversos riscos ocupacionais com material biológico. Com o intuito de contribuir com dados que auxiliem na formação acadêmica, propõe-se verificar a ocorrência, as características dos acidentes com material biológico, o conhecimento e a aplicação de ações preventivas e condutas pós-exposição. Trata-se de uma pesquisa observacional, transversal e descritiva utilizando um questionário de autopreenchimento aplicado a 195 estudantes do curso de Odontologia que tenham contato com procedimentos clínicos. Dos entrevistados, 23,6% sofreram acidentes ocupacionais, com predomínio do sexo feminino (78,3%), frequentemente acometendo as mãos (66,7%), e a maioria causados por sonda exploradora (30,1%). Observou-se que 34,9% sofreram acidentes percutâneos, somente 18,7% procurou auxílio médico e 6,3% relataram não usar equipamentos de proteção individual (EPI) no momento do acidente. Lavar o local afetado com água e sabão (54,7%) foi a principal conduta pós-exposição. A ocorrência de acidentes frente ao contato com material contaminado desperta atenção devido ao uso incompleto ou não uso de EPI, além da pouca procura por atendimento médico após os acidentes. Os acadêmicos relataram ter conhecimento da legislação relacionada à saúde do trabalhador e de como proceder em caso de acidentes ocupacionais. É necessário o desenvolvimento de estratégias de ensino que incluam uma supervisão mais eficaz, medidas que motivem a atenção para redução dos acidentes ocupacionais e o aumento da notificação de casos, de maneira contínua

Adenoid cystic carcinoma (ACC) is a malignant epithelial tumor of the salivary glands that commonly affects the minor salivary glands, and the palate is the most recurrent site. Treatment is challenging because this tumor tends to recur with distant metastases and poor prognosis. A 50-year-old woman complained of numbness in the upper left hemimaxilla, extended to the labial region, nose wing, and nasolabial sulcus, with clinical intra-oral alterations similar to an endodontic fistula tooth 25 palatal mucosa and discrete periapical rarefaction on radiologic evaluation. Endodontic treatment was provided with laser therapy administered for persistent numbness. After 3 months a palate volume increase and small ulcerated region were noted encompassing the region of teeth 24 to 27. The panoramic and tomographic examination was performed showing extensive bone destruction, and the patient underwent a biopsy followed by microscopic and immunohistochemistry evaluation and diagnosis as ACC. The patient was forwarded to a head and neck surgeon.

We aimed to identify and quantify the errors that dental students of UFES mostly commit when taking periapical radiographs. A total of 352 periapical radiographs was evaluated in this cross-sectional study. The radiographs were collected in the records of patients attended in the University in the last five years. Type of error and academic semester of the course were considered and data were submitted to the Chi-squared test at a significance level of 5%. The results demonstrated a high frequency of errors (84.37%) where the students in the 9th academic semester showed the highest frequency (92.30%) while those in the 8th academic semester had the lowest (70.00%) (p < 0.05). Improper storage (15.60%) was the most frequent error in the sample and it has not been quantified for academic environment in the literature to the best of our science. The other two most frequent errors were: inadequate positioning of the film (14.60%) and low radiographic density (10.60%). We concluded that most of the periapical radiographs taken by the dental students of UFES have errors. Attention should be given to the storage of film-based periapical radiographs in universities.

Objective: To radiographically evaluate the alveolar bone level after periodontal full mouth disinfection (FMD) treatment in women during chemotherapy (CHE) and hormone therapy with Tamoxifen (TAM). Material and Methods: This is an uncontrolled clinical trial with a convenience sample of women in antineoplastic treatment (CHE and TAM) and non-surgical periodontal FMD treatment. The Radiographic examination consisted of four bitewing radiographs and six periapical radiographs of the upper and lower anterior teeth, acquired according to the parallelling standard technique at three times: before (T0), 3 (T3) and 6 (T6) months after periodontal treatment. The alveolar crest level in the interproximal area of each tooth was measured by two calibrated observer using magnifying glass and digital caliper. Statistical analysis was performed for evaluation of the three times in each experimental group using the Friedman test (p 0.05). Conclusion: Patients undergoing chemotherapy and hormone therapy with Tamoxifen showed better alveolar bone levels after six months of periodontal FMD treatment. The current antineoplasic therapy did not influence the results obtained with periodontal treatment.

This study reported a clinical case about the use of salmon calcitonin in treatment of cherubism. A 12-year-old male melanoderm patient had bilateral expansion of the mandible and maxilla firm by palpation. The sclera below the iris showed the "look to the sky" classic description. The intrabuccal examination showed diastema, crowding, dental absences, and mobility of the lower central incisors. The radiologic examination showed multilocular radiolucent lesions in the maxillary tuberosities, paranasal region, and entire mandible, except the condyle. The treatment consisted of the daily administration of salmon calcitonin 200 UI nasal spray. Biochemical markers of calcium, phosphorus, and parathyroid remain within the reference values, while alkaline phosphatase has been elevated throughout the treatment. After 30 months of therapy, stabilization of the active bone lesion was observed without remission. The child is under periodic clinical and radiographic follow-up to evaluate the long-term therapy.

Purpose To determine whether calcified carotid atherosclerotic plaques (CCAPs) and mineralized laryngeal cartilages (MLCs) were more frequently detected on digital or film-based panoramic radiographs. The clinical relevance of this question is that some radiopacities seen on digital radiographs may correspond to medium-density tissues that are not necessarily mineralized. Materials and Methods Data were collected from panoramic radiographs and the respective reports issued by 2 private oral radiology centers. A total of 388 radiographs and reports were divided into film-based (group A) and digital (group D) radiographs. The frequencies of CCAPs and MLCs were analyzed using the Fisher exact test, and odds ratios were also calculated (α=1%). Results The mean age of patients whose reports and radiographs showed CCAPs and/or MLCs ranged from 50.1 to 54.1 years. There was a predominance of females. A higher frequency of CCAPs and MLCs was observed in group D than in group A at both centers (P

Este estudo teve como finalidades realizar uma análise comparativa entre duas técnicas radiográficas transcranianas com o auxílio do cefalostato ACCURAD-200, nas posições padrão e corrigida, e desenvolver um gabarito que auxilie o profissional a medir os espaços articulares anterior e posterior, fornecendo informações sobre o posicionamento condilar. Foram radiografados 59 pacientes, numa faixa etária entre 18 e 35 anos, que voluntariamente se propuseram a participar deste estudo. A correção da incidência do feixe central de radiação foi obtida com a radiografia ínfero-superior. Sobre as radiografias transcranianas, foram realizados os traçados com o auxílio dos gabaritos e feitas as medidas lineares dos espaços articulares, usando-se para tal um paquímetro digital. Nossos resultados demonstraram que, para ambas as técnicas empregadas, o espaço articular posterior apresentou-se menor que o anterior e que o método desenvolvido permite a avaliação do posicionamento condilarThe purpose of this study was to carry out a comparative analysis of two transcranial radiographic techniques with use of an ACCURAD-200 head holder in standard and corrected positions, and to produce a template to assist professionals in measuring anterior and posterior joint spaces to provide information on condyle positioning. Transcranial radiographs were taken of fifty-nine patients in the 18 to 35 age bracket who volunteered to take part in this study. The incidence of the central beam of radiation was corrected with an inferosuperior radiograph. Tracings were made on the transcranial radiographs with use of templates and the linear measures of joint spaces effected with a digital caliper rule. Results showed that for both techniques employed, the posterior joint space was smaller than the anterior, and that the method developed afforded an estimate of condylar position
