RESUMO
BACKGROUND: Analyze the clinical, demographic, histopathological, and immunohistochemical features of oral lymphoepithelial cyst (OLEC). METHODS: Samples were retrospectively retrieved from five oral pathology services. Clinical and demographic data were collected from patient charts. Histopathological and immunohistochemical (CD3 and CD20) features were evaluated. Data analysis involved descriptive statistics and bivariate analyses (P ≤ .05). RESULTS: Seventy-seven cases were found among a total of 146 150 specimens (0.05%). OLEC was predominantly diagnosed in females (70.1%). Mean patient age was 46.51 years. The lesions arose mainly on the lateral border of the tongue (40.3%), measured up to 1 cm (61.0%), and were asymptomatic (64.9%). Twenty-four lesions (31.2%) were white. Forty-one cases (53.2%) presented lymphocytic inflammatory infiltrate with no specific arrangement. The cystic lining was composed of a non-keratinized stratified epithelium (59.7%) presenting hyperplasia (39.0%). Connection with the surface, epithelium was found in 23 cases (29.9%) and 31 (40.3%) cases had two or more cystic cavities. The lumen content was predominantly desquamated cells (48.1%). Subgemmal neurogenous plaque was found in 11/42 (26.2%) cases involving the tongue. CD20+ cells predominated in 36/63 cases (57.2%), and lymphocytic inflammatory infiltrate was not always continuous around the cystic cavity (52.4%). CONCLUSION: Lymphoepithelial cyst is an uncommon lesion of the oral cavity. The present study offers the largest sample of OLEC for which clinical, demographic, histopathological, and immunohistochemical features were evaluated. The clinical and demographic findings were similar to those described in previous reports, but the microscopic analyses revealed interesting aspects of the cystic epithelium and the lymphocytic inflammatory infiltrate in OLEC.

Oral mucositis is a common acute complication of a head and neck squamous cell carcinoma treatment. Multiple scales can be used to diagnose and grade this lesion, but they all have some limitation regarding this group of patients. Most of these issues are associated with the hardness to differentiate signs and symptoms from oral mucositis vs. the inherent neoplasm. This study highlights the importance of a specifically developed scale for patients with head and neck squamous cell carcinoma.

The aim of this study was to investigate the epidemiological and clinical characteristics of chronic inflammatory periapical diseases in different regions of Brazil and to compare with data from the literature. A multicenter study was carried out in four Brazilian referral centers in oral diagnosis. Histopathological records were reviewed, and all cases diagnosed microscopically as periapical granuloma, radicular cyst, and periapical abscess were included. Demographic and clinical data were collected. Descriptive statistics and Pearson's chi-square test were performed. A total of 10,381 cases of chronic inflammatory periapical diseases were found (13.8% of 74,931 archived specimens) over a period of 65 years. Radicular cysts were the most common lesion (59.9%). Women (56.1%) with a mean age of 37.01 years old (range 13 to 100 ± 14.42) and people of white skin color (59.2%) were the most affected individuals by chronic inflammatory periapical diseases. The lesions were generally asymptomatic (28.1%), located in the maxilla (60.1%), and posterior region (49.8%). The radicular cysts were larger when compared to periapical granulomas (p < 0.001). The disagreement between the clinical and histopathological diagnoses was higher when the final diagnosis was a periapical granuloma (p < 0.001). Chronic inflammatory periapical diseases continue to be common lesions affecting mainly adults. This should be a consequence of the burden of untreated caries in permanent teeth. Women are more affected and radicular cyst was the most common lesion.

BACKGROUND: To evaluate the frequency and analyze demographic and clinical characteristics of individuals with a histopathological diagnosis of oral lymphatic malformations (OLMs). METHODS: A multicenter study was performed, collecting biopsy record data from a consortium of Brazilian Oral and Maxillofacial Pathology Centers. A review was also conducted to compare this data with cases already available in the literature. RESULTS: This study retrieved 208 cases of OLM in the multicenter study and 1035 cases in the literature review. In both, OLMs affected male and female individuals equally, with the most affected site being the tongue. Individuals ≥60 years of age were uncommonly affected. Symptomatic and larger lesions were more commonly reported in the literature review. CONCLUSIONS: This study comprises the largest sample of OLMs to date. OLMs are rare conditions, without sex predilection. The elderly proved to be less frequently affected, and the tongue is the most commonly affected site.

INTRODUCTION: The purpose of this study was to analyze the features of lesions obtained from biopsies at the periapical area of teeth with a radiographic or clinical initial diagnosis of apical periodontitis. METHODS: A retrospective study was conducted on biopsies obtained from 1953-2018 at 3 Brazilian oral and maxillofacial pathology centers. Cases of endodontic and nonendodontic periapical lesions (NPLs) with a clinical diagnosis of endodontic pathoses were retrieved. Data regarding patient age, sex, and anatomic location were obtained from patients' records. The frequency and percentage of cases with clinical diagnoses of a periapical cyst, periapical granuloma, or dentoalveolar abscess were recorded, and the final histopathologic diagnosis was documented. RESULTS: Among 66,179 oral biopsies, 7246 (10.94%) were clinically diagnosed as periapical disease, 306 (4.22%) of which were histopathologically diagnosed as NPLs. The most frequent NPLs were odontogenic keratocysts (n = 107, 34.96%) followed by dentigerous cysts (n = 48, 15.68%). The mean age at diagnosis was 39.68 years with a range of 6-80 years. A total of 159 (51.96%) cases occurred in females and 147 (48.03%) in males (female to male ratio = 1.08:1). Most lesions (137, 44.77%) were located in the posterior mandible. CONCLUSIONS: A wide variety of histopathologic diagnoses, including benign odontogenic and nonodontogenic cystic and tumorous lesions, infectious diseases, and malignant neoplasms, was reported in the present survey. The features presented in this study were consistent with previous findings reported in the literature.

Purpose: The purpose of this systematic review was to summarize the clinical and radiographic results of pulp revascularization procedures employing a triple antibiotic paste in teeth with incomplete root formation. Methods: Electronic searches were conducted in February 2017 using PubMed, Medline, Web of Science, Scopus, The Cochrane Library, ProQuest, Lilacs and The Brazilian Library of Dentistry, UK National Institute for Health and Care Excellence, U.S. National Institutes of Health, Clinical Trials, and Google. The search was updated in March 2019. Clinical trials in English, Portuguese, and Spanish, without any restrictions regarding the year of publication, were included. The quality of the studies was analyzed using the Cochrane Collaboration tool. Results: The search retrieved 1,768 references, and eight studies were included for a qualitative analysis. In these eight studies, the risk of bias across the Cochrane tool's domains varied from low to unclear. The included studies demonstrated that the clinical and radiographic success of pulp revascularization using calcium hydroxide or triple antibiotic paste appears to resolve symptoms and periapical healing. Conclusions: Triple antibiotic paste is effective in the pulp revascularization therapy of teeth with incomplete root formation. Absence of symptoms and the achievement of periapical integrity have been observed. (Pediatr Dent 2019;41(5):341-53).

Cytokines and chemokines have a fundamental role in the maintenance of inflammation and bone response, which culminate in the development of chronic periapical lesions. Regulatory (Treg) and Th17 cytokines play a key role in regulating the immune response involved in this process. The aim of this study was to investigate the role of Treg and Th17 cells in chronic inflammatory periapical disease, by comparing the expression of the immunoregulatory mediators TGF-ß, IL-10, CCL4, and the proinflammatory IL-17 and CCL20 in the periapical tissue of teeth with pulp necrosis, with and without associated chronic lesions. Eighty-six periapical tissue samples were obtained from human teeth. The samples were divided into three groups: pulp necrosis with a periapical lesion (n=26); pulp necrosis without a periapical lesion (n=30), and control (n=30). All samples were submitted to histopathological analysis and cytokine and chemokine measurement through ELISA. Statistical analyses were done with Kruskal-Wallis and Mann-Whitney tests and Spearman correlation. The group with pulp necrosis and a periapical lesion showed a higher expression of CCL4 and TGF-ß in comparison with pulp necrosis without a lesion. CCL20 was higher in the group with a periapical lesion when compared to the control. In all groups there was a weak positive correlation between IL-17/CCL20, IL-10/CCL4, and IL-17/TGF-ß. Both types of cytokines, pro-inflammatory and immunoregulatory, occur simultaneously in periapical tissue. However, a rise in immunosuppressive cytokines and chemokines (CCL4 and TGF-ß) in periapical lesions suggests a role of these cytokines in stable periapical disease.

Resumo Introdução Dados de autopercepção da saúde bucal são importantes para a avaliação do paciente de forma integral. Objetivo Investigar a relação entre as percepções dos pais/cuidadores quanto à necessidade de tratamento ortodôntico em escolares de 12 anos de escolas públicas de Juiz de Fora e os fatores associados, incluindo acesso aos serviços de saúde bucal. Método Foi realizado um estudo transversal (n = 311), no qual os pais/cuidadores responderam sobre a necessidade de tratamento ortodôntico dos escolares, nível socioeconômico, grau de instrução do chefe da família e acesso aos serviços de saúde bucal. Para avaliar a necessidade normativa de tratamento ortodôntico dos escolares, foi utilizado o índice de estética dental e foi direcionada a eles uma pergunta sobre sua percepção em relação à necessidade de tratamento. Nas análises estatísticas, foram realizados o teste qui-quadrado de Pearson, o teste exato de Fisher ou qui-quadrado de tendência linear e a regressão logística, com nível de significância p < 0,05. Resultados A necessidade normativa de tratamento ortodôntico (p = 0,001) e a autopercepção da necessidade de tratamento ortodôntico pelo escolar (p < 0,001) foram associadas estatisticamente à percepção da necessidade de tratamento ortodôntico pelos pais/cuidadores. Conclusão A percepção da necessidade de tratamento ortodôntico, tanto pelos pais/cuidadores quanto pelos escolares, foi expressivamente maior que a necessidade normativa de tratamento ortodôntico.
Abstract Background self-perception data on oral health are important for comprehensive patient's assessment. Objective to investigate the relationship between parents/caregivers' perceptons on the need of orthodontic treatment in 12-year-old schoolchildren of public schools of Juiz de for a, and associated factors, including access to oral health services. Method cross-sectional study (n=311). Parents/caregivers answered questions about their perceptions on the need of orthodontic treatment in schoolchildren, socioeconomic level, head of familiy's education level, and access to oral health services. Schoolchildren's normative orthodontic treatment need was assessed tbased on the Dental Aesthetic Index. Schoolchildren also provided their perceptions on the need of orthodontic treatment. Pearson Chi-square, Fisher Exact test or Linear by Linear Association were used for statistical analysis, in addition to logistic regression with significance level p<0.05. Results normative orthodontic treatment need (p=0.001) and the schoolchildren's perception on their orthodontic treatment need (p<0.001) were statistically associated with parents/caregivers perceptions regarding orthodontic treatment need. Conclusion Parents/caregivers and children's perceptions on the need of orthodontic treatment were significantly greater than children's normative orthodontic treatment need.

AIMS: Transcatheter aortic valve implantation has emerged as an alternative to conventional aortic valve replacement in high-risk patients. Diverse prostheses are currently under investigation. The aim of this study was the clinical, safety and efficacy assessment of Braile Inovare Transcatheter Aortic Prosthesis usage. METHODS AND RESULTS: Ninety high-risk or inoperable patients underwent transcatheter aortic valve implantation. The mean logistic EuroSCORE was 39.3%. All patients presented calcified aortic stenosis. The procedures were performed under fluoroscopic and echocardiographic guidance. Prostheses were implanted through the transapical approach under rapid ventricular pacing. Echocardiographic and angiographic controls were included. Implantation was feasible in 87 cases. There was only one case of operative mortality, and 30-day mortality was 13.3%. The median transvalvular aortic gradient was reduced from 44.8±15.3 to 14.1±8.0 mmHg. Left ventricular function improved in the first seven postoperative days. Paravalvular aortic regurgitation was present in 29.7% of cases, mostly trace. One case presented a major vascular complication, and there were two cases of permanent pacemaker implantation. Two cases of major stroke occurred. CONCLUSIONS: Transcatheter aortic valve replacement using the Braile Inovare prosthesis is able to provide encouraging results with significant functional and structural cardiac improvement. It is mandatory to continue follow-up to measure the benefits of this device as well as to improve selection criteria of patients.

OBJECTIVE: Aortic valve replacement for bioprosthesis dysfunction is a procedure involving considerable risk. In some cases, mortality is high and may contraindicate the procedure. Minimally invasive transcatheter aortic "valve-in-valve" implant appears to be an alternative, reducing morbidity and mortality. The objective is to evaluate aortic valve-in-valve procedure using Braile Inovare prosthesis. METHODS: The Braile Inovare prosthesis, transcatheter, expandable balloon, was used in 14 cases. Average EuroSCORE was 42.9%. All patients had double aortic bioprosthesis dysfunction. Procedures were performed in a surgical hybrid environment under echocardiographic and fluoroscopic guidance. Using left minithoracotomy prostheses were implanted through the ventricular apex under high-frequency ventricular pacing. Serial clinical and echocardiographic controls were performed. Follow-up ranged 1-30 months. RESULTS: Correct prosthetic deployment was obtained in all cases. There was no conversion. There was no operative mortality. The 30-day mortality was 14.3% (two cases). Ejection fraction increased significantly after the 7th postoperative day. Aortic gradient significantly reduced. The residual aortic regurgitation was not present. There were no vascular complications or complete atrioventricular block. CONCLUSION: The transcatheter "valve-in-valve" procedure for bioprosthesis dysfunction is safe with low morbidity. This possibility may change prosthesis choice during the first aortic valve replacement, favoring bioprostheses.

Introdução: as periapicopatias inflamatórias de origem endodôntica são as doenças mais frequentes dos ossos maxilares e ocorrem principalmente como consequência da disseminação da infecção endodôntica. Apesar de vários estudos, não existem dados recentes sobre as características epidemiológicas e clínicas dessas lesões envolvendo uma amostra tão grande da população. Objetivo: Investigar as características epidemiológicas e clínicas das periapicopatias inflamatórias de origem endodôntica, incluindo o granuloma periapical, o cisto radicular e o abscesso periapical. Metodologia: foi realizado um estudo retrospectivo e multicêntrico em quatro instituições com centros de referência em diagnóstico oral no Brasil. Todos os registros histopatológicos foram revisados e foram incluídos todos os casos diagnosticados microscopicamente como granuloma periapical, cisto radicular e abscesso periapical. Foram coletados os seguintes dados demográficos e clínicos: sexo, idade e cor da pele dos pacientes, sintomas, duração, tamanho e localização das lesões e concordância entre o diagnóstico clínico e histopatológico. Análises estatísticas descritivas e bivariadas, utilizando o teste Qui-quadrado de Pearson, foram realizadas. Em casos de variáveis com mais de duas categorias, utilizou-se o teste Z para comparação das proporções de colunas e a correção de Bonferroni. Valores de p < 0,05 foram considerados estatisticamente significativos. Resultados: foram encontrados 10.381 casos de lesões periapicais entre 74.931 espécimes arquivados (13,8%) em 65 anos. Os cistos radiculares foram as lesões mais comuns (59,9%). As lesões periapicais acometeram principalmente mulheres (56,1%), com média de idade de 37,01 anos (13 a 100 ± 14,42 anos) e cor de pele branca (59,2%). As lesões eram geralmente assintomáticas (28,1%), persistindo por mais de um ano (13,3%), com tamanho de até 10 mm (25,2%) e localizadas na maxila (60,1%) e região posterior (49,8%). Os cistos radiculares foram maiores (p < 0,001), com maior ocorrência de sintomatologia (p < 0,027) e maior frequência na região posterior (p < 0,001) em relação aos granulomas periapicais. A possibilidade de discordância entre o diagnóstico clínico e histopatológico foi maior nos granulomas periapicais (p < 0,001). Conclusões: as periapicopatias inflamatórias de origem endodôntica foram comuns em serviços de Patologia Bucomaxilofacial, acometendo principalmente adultos. Isso deve ser uma consequência da carga de cáries não tratadas em dentes permanentes. As mulheres são mais afetadas e o cisto radicular é a lesão mais comum.
Introduction: Inflammatory periapical lesions are the most frequent diseases of maxillary bones and occur mainly as a consequence of the dissemination of endodontic infection. Despite several studies, there are no recent data on the epidemiological and clinical characteristics of these lesions involving such a large sample. Objective: To investigate the epidemiological and clinical characteristics of periapical lesions, including periapical granuloma, radicular cyst and periapical abscess. Methodology: A multicenter retrospective study was realized in four institutional reference centers in oral diagnosis in Brazil. Histopathological records were reviewed and included all cases diagnosed microscopically as periapical granuloma, radicular cyst and periapical abscess. Data on patient sex, age, skin color, symptoms, lesion duration, lesion size, lesion location and concordance between clinical and histopathological diagnosis were collected. Descriptive statistics and bivariate analyses using Pearson's Chi-square test were done. A z-test, to compare the column proportions, and Bonferroni correction were used, in the case of variables with more than two categories. P values < 0.05 were considered statistically significant. Results: Were found 10,381 cases of periapical lesions among 74,931 archived specimens (13.8%) in 65 years. Radicular cysts were the most common lesions (59.9%). Periapical lesions affected mainly women (56.1%), with a mean age of 37,01 years (range 13 to 100 ± 14,42) and white-skinned (59.2%). The lesions were generally asymptomatic (28.1%), persisting for more than one year (13.3%), size up to 10 mm (25.2%) and located in the maxilla (60.1%) and posterior region (49.8%). The radicular cysts were larger (p < 0.001), with a higher occurrence of symptomatology (p < 0.027) and higher frequency in the posterior region (p < 0.001) compared to periapical granulomas. The possibility of disagreement between clinical and histopathological diagnosis was higher in periapical granulomas (p < 0.001) than radicular cyst. Conclusions: Endodontic periapical lesions were common in the Bucomaxillofacial Pathology services affecting mainly adults. This should be a consequence of the burden of untreated caries in permanent teeth. Women are more affected and radicular cyst is the most common lesion.

INTRODUÇÃO: A reoperação para substituição de biopróteses aórticas com disfunção é procedimento que envolve considerável risco. Em alguns casos, a mortalidade é elevada e pode contraindicar o procedimento. O implante minimamente invasivo "valve-in-valve" transcateter de valva aórtica parece ser uma alternativa, reduzindo morbimortalidade. O objetivo deste estudo foi avaliar esses implantes utilizando a prótese Braile Inovare. MÉTODOS: A prótese Braile Inovare, transcateter, balão expansível foi utilizada em 14 casos. Euroscore médio foi de 42,9%. Todos os pacientes eram portadores de dupla disfunção de bioprótese aórtica. Os procedimentos foram realizados em ambiente cirúrgico híbrido, sob controle ecocardiográfico e fluoroscópico. Por meio de minitoracotomia esquerda, as próteses foram implantadas através do ápice ventricular, sob estimulação ventricular de alta frequência. Foram realizados controles clínicos e ecocardiográficos seriados. O seguimento variou de 1 a 30 meses. RESULTADOS: A correta liberação protética foi possível em todos os casos. Não ocorreu conversão. Não houve mortalidade operatória. A mortalidade em 30 dias foi de 14,3% (dois casos). A fração de ejeção apresentou aumento significativo após o 7º pós-operatório e o gradiente aórtico apresentou redução significativa. A insuficiência aórtica residual não esteve presente. Não ocorreu complicação vascular periférica ou bloqueio atrioventricular total. CONCLUSÕES: O implante "valve-in-valve" de valva aórtica transcateter em biopróteses com disfunção é um procedimento seguro e com morbimortalidade baixa. Essa possibilidade poderá alterar a indicação de seleção de prótese no procedimento inicial, favorecendo próteses biológicas.
