RESUMEN

Mandibular third molar (M3) removal is a routine surgical procedure that can generate a variety of complications, one of the rarest of which is mandibular fracture. The aim of this paper is to report a rare case of bilateral fracture of the jaw during the extraction of mandibular third molars. A 42-year-old woman complained of mandibular pain and malocclusion after the removal of the M3s. The physical examination revealed bone crepitation mandibular bilaterally. Computed tomography confirmed bilateral fracture of the jaw. The patient was submitted to the reduction and fixation of the fractures under general anesthesia, followed by the improvement in the postoperative period. Bilateral mandibular fracture resulting from M3 extractions is a rare occurrence that may be caused by a lack of surgical skill and a flawed diagnosis. The proper, immediate correction could lead to the interruption of the procedure at the time of the first fracture, thereby avoiding the contralateral fracture. Key words:Molar surgery, mandibular fracture, complication.

RESUMEN

Introdução: A osteotomia Le Fort I possibilita a correção de deformidades dentofaciais que envolvem o terço médio da face. Para sua fixação, convencionou-se o emprego de quatro mini-placas nos pilares zigomático-maxilar e nasomaxilar. Propôs-se então, a dispensa da fixação do segmento posterior, surgindo questionamentos relacionados à capacidade biomecânica do sistema. Objetivos: Comparar o estresse biomecânico gerado em três meios distintos de fixação da osteotomia Le Fort I frente ao movimento de avanço sagital linear maxilar de 7mm. Metodologia: Trata-se de uma pesquisa experimental laboratorial, utilizando-se da análise de elementos finitos como ferramenta analítica, a fim de constatar qual das técnicas sofrerá maior estresse biomecânico. Resultados: Constatou-se que o estresse biomecânico gerado é maior quando aplicado em 4 pontos do que quando aplicado em apenas 2 pontos. Conclusão: Os resultados obtidos fornecem informações aos cirurgiões sobre a real necessidade do uso de fixação adicional de acordo com o método de fixação planejado. No entanto, deve ser interpretado de forma cautelosa, considerando-se as limitações deste estudo. Sendo assim, uma análise incipiente, que tem como intuito o fornecimento de evidência científica de grande significância.

Introduction: The Le Fort I osteotomy allows the correction of dentofacial deformities involving the middle third of the face. For its fixation, it was agreed to use four mini plates on the zygomaticomaxillary and nasomaxillary pillars. It was then proposed to dispense with the fixation of the posterior segment, raising questions related to the biomechanical capacity of the system. Objectives: To compare the biomechanical stress generated in three different means of fixation of the Le Fort I osteotomy against a 7mm maxillary linear sagittal advancement movement. Methodology: This is an experimental laboratory research, using finite element analysis as an analytical tool, in order to verify which of the techniques will suffer greater biomechanical stress. Results: It was found that the biomechanical stress generated is greater when applied to 4 points than when applied to only 2 points. Conclusion: The results obtained provide information to surgeons about the real need to use additional fixation according to the planned fixation method. However, it should be interpreted with caution, considering the limitations of this study. Therefore, an incipient analysis, which aims to provide scientific evidence of great significance.

RESUMEN

OBJECTIVE: The objective of this systematic review with meta-analysis was to critically evaluate the available data on sensitivity and specificity of IHC compared with molecular tests in the detection of BRAF V600E mutation in ameloblastomas. MATERIALS AND METHODS: This systematic review was performed based on the PRISMA statement and registered in Prospero (CRD42021259117). PubMed, Web of Science, Scopus, and Cochrane Library databases were searched for observational studies to answer the question "What is the diagnostic accuracy of immunohistochemistry compared with molecular tests for the diagnosis of BRAF V600E mutation in ameloblastomas?". Methodological quality and risk of bias assessment of the selected studies were based on the QUADAS-2. Meta-analysis based on hierarchical SROC curve model and summary measures for sensitivity and specificity were computed. RESULTS: A total of 226 records were found, but only 05 articles met the inclusion criteria, with 277 FFPE specimens of ameloblastoma included in the quantitative analysis. The sensitivity of the IHC compared to molecular tests ranged from 0.71 to 1.00, while all of the included studies showed perfect specificity (1.00). Pooled measures for sensitivity and specificity were 0.95 [95% CI 0.89, 1.00] and 1.00 [95% CI 0.95, 1.00], respectively. The diagnostic odds ratio was 4.05, and the AUC for SROC curve was calculated as 0.979. CONCLUSIONS: BRAF V600E-specific IHC using VE1 antibody showed extremely high sensitivity and specificity when compared with molecular tests in the detection of the mutation in ameloblastomas.

RESUMEN

Background: Oral Potentially Malignant Disorders (OPMDs) are defined as lesions with a greater likelihood ofprogressing to cancer. Population-based studies that evaluate the prevalence of OPMDs are scarce in Brazil. Theaim of the present study was to determine the prevalence of OPMDs and associated risk factors in a semi-urbanBrazilian population.Material and Methods: This is a cross-sectional study, whose universe included individuals aged 40 years or olderresiding in a medium-sized city of northeastern Brazil. Data collection was divided into two steps: interview andoral examination. The outcome variable was the presence of OPMDs. The predictor variables were sociodemo-graphic characteristics and risk habits. The bivariate analysis was performed through chi-square test. The crudeprevalence ratios (PR) and its respective 95% confidence intervals (CI) were calculated. Poisson regression analy-sis with robust variance was used to calculate adjusted PRs and 95% CI.Results: Three hundred fourteen individuals were included in the study. When asked about risk habits, 58.9%reported being current smokers or ex-smokers and 62.2% reported being current drinkers or ex-drinkers. Theprevalence of OPMDs was 7.6% and was significantly higher among individuals with black skin color (p < 0.001),alcohol users (p = 0.017), and individuals with both tobacco and alcohol habits (p = 0.012).Conclusions: Therefore, the population in the present study had a high frequency of risk habits associated withPMDs of the oral cavity.(AU)

RESUMEN

Introdução: Os sialólitos são lesões mineralizadas nas glândulas salivares que causam obstrução total ou parcial do ducto, acometendo comumente a glândula submandibular. Sua abordagem varia de pouco invasiva à cirúrgicas, a depender do número, localização e dimensões dos cálculos. Objetivo: Esse estudo teve como objetivo relatar um caso clínico raro de sialólito no ducto da glândula parótida tratado através da remoção cirúrgica. Relato De Caso: Paciente compareceu ao ambulatório com história de dor e edema em face com 2 meses de evolução, referindo piora da sintomatologia após alimentação. Ao exame físico apresentou edema endurecido em região pré-auricular esquerda e ausência de drenagem no ducto da parótida ipsilateral. Foi realizado uma radiografia de tecidos moles com filme periapical, que revelou imagem radiopaca circunscrita sugestiva de um sialólito no ducto da glândula parótida esquerda. Assim, foi realizada excisão cirúrgica do cálculo seguida do reestabelecimento da patência ductal através da instalação de cateter venoso. Paciente evoluiu bem e segue em acompanhamento sem recidiva dos sinais e sintomas. Considerações Finais: O presente estudo revela que o diagnóstico precoce da sialolitíase e a escolha do plano de tratamento adequado estão associados a um bom prognóstico, e o reestabelecimento da patência ductal, quando danificado, é imprescindível para o sucesso do tratamento(AU)

Introduction: Sialoliths are mineralized lesions in the salivary glands that cause total or partial obstruction of the duct, commonly affecting the submandibular gland. It ranges from less invasive to surgical approach, depending on the number, location and dimension of the calculi. Objective: This study aimed to report a rare clinical case of a sialolith in the parotid gland's duct treated by surgical removal. Case Report: The patient attended the outpatient clinic with a history of pain and edema in the face with 2 months of evolution, reporting worsening symptoms after feeding. On physical examination, he had hardened edema in the left preauricular region and no drainage in the ipsilateral parotid duct. Soft tissue radiography with a periapical film was performed, which revealed a circumscribed radiopaque image suggestive of a sialolith in the left parotid gland's duct. Thus, the calculus's surgical excision was performed, followed by the reestablishment of the ductal patency through the installation of a venous catheter. The patient evolved well and is being followed up without recurrence of signs and symptoms. Final Considerations: The present study reveals that the early diagnosis of sialolithiasis and the choice of the appropriate treatment plan are associated with a good prognosis, and the reestablishment of ductal patency, when damaged, is essential for the success of the treatment(AU)

RESUMEN

OBJECTIVE: SARS-CoV-2 has high human-human transmission rate. The aerosols and saliva droplets are the main contamination source. Thus, it is crucial to point out that dental practitioners become a high-risk group of contagion by SARS-CoV-2. Based on this, protocols have been recommended to avoid cross-contamination during dental care; however, appropriate evidence has not yet been established. Our study sought to make a screening, by in silico analysis, of the potential of mouth rinses used in dental practices to prevent the dental workers' contamination by SARS-CoV-2. METHODOLOGY: Multiple sequence comparisons and construction of the phylogenetic tree were conducted using the FASTA code. Therefore, molecular docking investigation between SARS-CoV-2 proteins (Main Protease, Spike Glycoprotein, Non-structure Protein, and Papain-like Protease) and molecules used in dental practices (chlorhexidine digluconate, hydrogen peroxide, cetylpyridinium chloride, povidone-iodine, gallic acid, ß-cyclodextrin, catechin, and quercetin) was performed using AutoDock Vina. Moreover, 2D interactions of the complex protein-ligand structure were analyzed by Ligplot+. RESULTS: The obtained results showed a remarkable affinity between SARS-CoV-2 proteins and all tested compounds. The chlorhexidine digluconate, catechin, and quercetin presented a higher affinity with SARS-CoV-2. CONCLUSIONS: The overall results allowed us to suggest that chlorhexidine is the most suitable active compound in reducing the SARS-CoV-2 salivary load due to its better binding energy. However, in vivo studies should be conducted to confirm their clinical use.

RESUMEN

The purpose of this systematic review was to summarize the available data on TMJ chondrosarcomas and to perform a survival analysis of cases reported to date. This review was conducted in accordance with the PRISMA. Two authors performed an electronic search of case reports of TMJ chondrosarcoma published until August 02, 2020. Forty-seven studies reporting 53 cases were included. Chondrosarcomas of the TMJ were more prevalent in women, with a male:female ratio of 1:1.4. Survival curves were significantly associated with histological diagnosis (p = 0.004), reconstructive surgery (p = 0.024), recurrence (p < 0.001), and distant metastasis (p = 0.001). Only distant metastasis was independently associated with survival (p = 0.017). TMJ chondrosarcomas presented with low recurrence and higher survival rates than other chondrosarcomas. Synovial subtype, absence of reconstructive surgery, and presence of local recurrence or distant metastasis were associated with poorer prognosis.

RESUMEN

Background: The preemptive use of anti-inflammatory drugs, such as corticosteroids and NSAIDs, has the po-tential to reduce pain, swelling and trismus following oral surgery. The aim of this study was to compare theefficacy of dexamethasone and ketorolac tromethamine in reducing pain, swelling and trismus after mandibularthird molar removal.Material and Methods: The researches implemented a triple-blind, randomized clinical trial. The study was con-ducted with ASA I individuals aging between 18 and 35 years, which were randomized and submitted to twointerventions, one with 8mg dexamethasone and the other with 20mg ketorolac tromethamine given 1h before theprocedure. The primary predictor variable was the use of dexamethasone or ketorolac. The primary outcome vari-able was the postoperative pain level, measured with a Visual Analogue Scale. The secondary outcome variableswere the amount of rescue analgesic consumed, swelling and trismus. Repeated-measures ANOVA and t-test forpaired samples were used to compare the means. Significance was set at p < 0.05.Results: Fifty individuals were randomized and allocated to intervention, and the sample was composed of 40subjects who completed the study (27 female and 13 male). Dexamethasone, when compared to ketorolac trometh-amine, showed a significantly higher reduction in pain level at 8h, 16h, 24h, 32h, 40h and 72h, in swelling and tris-mus at 24h, 48h, 72h and 7 days and in total number of rescue analgesics taken up to 72h postoperative (p < 0.05). Conclusions: The clinical performance of dexamethasone in controlling pain, swelling and trismus after mandibularthird molar removal was superior to ketorolac tromethamine’s.(AU)

RESUMEN

Resumo Objetivo Estimar a prevalência do deficit cognitivo e verificar associações com variáveis sociodemográficas e de saúde em idosos de Unidades Básicas de Saúde (UBSs) de uma cidade no interior do nordeste brasileiro. Método Estudo transversal de prevalência e associação a respeito da população idosa. Os instrumentos utilizados para coleta dos dados foram Miniexame do Estado Mental (função cognitiva), Escala de Depressão Geriátrica Abreviada (sintomas depressivos), Escala de Lawton (capacidade funcional), Miniavaliação Nutricional (estado nutricional) e teste Timed Get Up and Go (risco de quedas). A associação bivariada entre o deficit cognitivo e as variáveis independentes foi avaliada pelo teste qui-quadrado. A análise multivariada foi feita usando um modelo de regressão logística com as razões de prevalência (RP) e intervalo de confiança de 95% (IC95%). Resultados Foram avaliados 818 idosos. A prevalência de deficit cognitivo foi de 65,9% (IC95%=62,50 - 69,10). Ao compor o modelo de análise multivariada, verificou-se maior ocorrência de deficit cognitivo em indivíduos mais velhos (RP=1,48; IC95%=1,07-2,05), funcionalmente dependentes (RP=3,27; IC95%=2,01-5,10), analfabetos (RP=1,66; IC95%=1,15-2,40) e com risco de desnutrição ou desnutridos (RP=2,09; IC95%=1,47-2,96). Conclusão O presente trabalho evidenciou alta prevalência de deficit cognitivo e que foi associada à idade, escolaridade, capacidade funcional e estado nutricional. É possível questionar se isso se deve à grande quantidade de pessoas com comprometimento cognitivo leve sem demência com remissão posterior dos sintomas, ou pela ocorrência de demência de início precoce.

Abstract Objective To estimate the prevalence of cognitive deficit and verify associations with sociodemographic and individual health variables in senior patients from units in the primary health system. Method Prevalence and association study about the elderly population. The instruments used were the Mini-Mental State Examination (cognitive function), Shorten Geriatric Depression Scale (depression symptoms), Lawton Scale (functional capacity), Mini-Nutritional Assessment (nutritional state), and Timed Up and Go Test (fall risk). The association between cognitive deficit and independent variables was verified by the Chi-square test. Multivariate analysis was performed using a logistic regression model with the prevalence ratio (PR) and 95% confidence interval (95%CI). Results The data were collected from 818 old-aged patients. The cognitive deficit had a prevalence of 65.9% (95%CI= 62.50-69.10). In the multivariate analysis model, it was verified a larger occurrence of cognitive deficit individuals, with risks of malnutrition (PR=2.09; CI95%=1.47-2.96), illiteracy (PR=1.66; 95%CI=1.15-2.40), dependents (PR=3.27; 95%CI=2.01-5.10), and with more than 70 years old (PR=1.48; 95%CI=1.07-2.05). Conclusion The present study showed a high prevalence of cognitive deficit and was associated with age, education, functional capacity, and nutritional status. It is possible to question if it is caused by the big amount of people with mild cognitive impairment without dementia with posterior remission of the symptoms, or by the occurrence of early start dementia.

RESUMEN

Introdução: Tendo em vista a importância do campo da patologia oral e maxilofacial, faz-se necessário compreender o impacto da mais recente Classificação dos Tumores de Cabeça e Pescoço da OMS na frequência e distribuição dos cistos e tumores odontogênicos. Este estudo teve como objetivo estabelecer a frequência de lesões odontogênicas ao longo de 12 anos, em um serviço de referência em Patologia Oral, no Nordeste brasileiro. Metodologia: Os casos diagnosticados como cisto (OC) ou tumor (OT) odontogênico de 1999 a 2010 foram revisados e reclassificados de acordo com a atual Classificação da OMS de Tumores de Cabeça e Pescoço. Foram analisados dados referentes ao diagnóstico histopatológico, à localização da lesão, à idade, ao sexo e à etnia. A análise dos dados bivariados foi realizada, calculando-se as razões de prevalência, o teste do qui-quadrado e o teste exato de Fisher. Resultados: Entre 3.034 espécimes, 409 foram OC e 199 foram OT. Os Oc mais frequentes foram o cisto radicular (n = 129) e ceratocisto odontogênico (n = 99).

RESUMEN

Uma das principais causas de insucesso das reabilitações implanto suportada está relacionada à inflamação dos tecidos de sustentação peri-implantar a longo prazo. Mucosites podem ser definidas como alterações inflamatórias reversíveis dos tecidos moles periimplantares que não sofreram perda óssea. O conceito de mucosite alude a uma reação inflamatória de caráter reversível, sem perda óssea, equivalente à gengivite do periodonto. É caracterizada, principalmente, pela dor, sangramento gengival, eritema e ulcerações. A prevalência de complicações após a restauração oral com próteses implantosuportadas é alta. No entanto, existem poucos trabalhos na literatura sobre esse tipo de complicações, o que torna difícil comparar os resultados e avaliar se a presença de problemas protéticos é frequente ou não. Este trabalho tem como objetivo realizar o relato de caso de mucosite peri-implantar e discutir os principais métodos de tratamento e prevenção desse processo patológico... (AU)

The principal complication causes of failure of implant supported restorations is related to inflammation of the peri-implant tissues support the long term. Mucositis can be defined as reversible inflammatory changes in the peri-implant soft tissues that has not undergone bone loss. The concept of mucositis refers to an inflammatory reaction reversible character without bone loss, equivalent to periodontal gum disease. It is characterized by pain, gingival bleeding, erythema and ulceration. The prevalence of complications after oral restoration with implants supported dentures hybrids is high. However, there are few studies on this type of complications, which makes it difficult to compare results and assess whether the presence of prosthetic problems is frequent or not. This work aims to realize the case of peri-implant mucositis and discuss the main methods of treatment and prevention of this disease process... (AU)

RESUMEN

Os cistos inflamatórios periapicais representam uma considerável parcela na distribuição epidemiológica daqueles categorizados como odontogênicos. Estudos mostram que no mundo inteiro cerca de 84% dos cistos que acometem a região maxilo facial são inflamatórios pariapicais. Seu diagnóstico é realizado pela associação entre o exame clínico, imaginológico e histopatológico. a terapêutica dessas lesões compreende desde o tratamento endodôntico dos dentes envolvidos até a sua enucleação cirúrgica. Fatores, como o estado geral do paciente, tamanho, forma e localização da lesão, são relevantes na tomada de decisões em casos como esses. Este trabalho tem como propósito relatar um caso clínico de um extenso cisto inflamatório periapical na maxila e discutir os fatores que levaram a uma abordagem multidisciplinar.

Inflammatory periapical cysts represent a considerable share in the epidemiological distribution of those categorized as odontogenic. Studies show that about 84% of cysts affecting the maxillofacial region in the world, are inflammatory pariapicais. Its diagnosis is made by the association between clinical examination, imaging and histopathology.
